Adding a Reverse to Forwards Only ESC?

Thanks JB, that is very encouraging. …and a neat little video to show it in action too. Plenty of room in just about any of my Classic Model Power Boats to fit it too, so I will start looking for a source of supply for a similar 10A 240V switch. Bob.

Adding a Reverse to Forwards Only ESC?

When I started back making and restoring Classic Model Power Boats after several years of being away from the hobby, I had to make the change from using the ic motors that I loved and understood to those soulless (but very efficient) electric motors. Old habits die hard, and so water-cooling everything, and only needing to run in a forwards direction (we never have reverse on our glow plug motors) came with me. The result is that almost all of my electric speed controllers (ESC) are forwards only and water-cooled. Most of my speed controllers are made by SeaKing or are clones or rebranded Sea King ESC’s. They work really well and have all been 100% reliable (so far!). What I would like to know is, can I add a reverse function and still keep all of my Sea King ESC’s? Is there a basic switching function that can be added simply that will allow me to operate the same ESC to drive the motor backwards - at the flick of a switch? I have a lot of these Sea King ESC, but the electric motors in all of my boats can go backwards as well as forwards, so I would like to add this function to my Classic Model Power Boats - preferably without having to dump all of my Sea King speedos and change them for a different type that comes with the forwards and reverse function in-built. Any help, advice of ideas regarding this would be greatly appreciated . Bob.

SEMI SCALE FOAM AND GLASS MODEL OF MY 15FT 1953 SCHOCK US DESIGN DAY SAILER. CREW ADDED

Thought I'd add something to lend a bit of realism to the boat, (all boats need a crew) 'Bob' was disemboweled and had part of an aileron horn inserted in his nether region. A servo tray was made under the seat, and a cord from the servo arm runs back, round a 'pulley' and connects to the aforementioned insertion. His right arm was amputated and joints converted to macrame string for extra flexibility. His rear is screwed to the seat between the slats (seat slats) ☹️. Seats are located with tabs so they can be removed easily. 'Bob' and his seat comes out as a unit. Seems to work ok, but he's complaining about the lumps on his head😠 A vid of the first test. Also made a quick new cheap stand for the boat. JB https://www.youtube.com/watch?v=KOn-fkVffuw https://www.youtube.com/watch?v=cLSVecCPh5c

SEMI SCALE FOAM AND GLASS MODEL OF MY 15FT 1953 SCHOCK US DESIGN DAY SAILER.

After the success with the A class catamaran, (glass on foam) I was looking for something new to build using the same method. I've been wanting to do another model of one of my full sized boats, so thought the day sailer would be a good subject. Model is 1m long. Made a sandwich of 4 x 25mm foam sheets on the 5mm ply deck cutout, glued with foam safe contact spray. The area around the cockpit was only glued round the edges, as 2 sheet thicknesses had to be removed later. The big foam sandwich was shaped by eye with a Surform file when dry, using the laminate lines for reference. The full sized boat had been measured previously, and everything scaled 20%, and lines drawn on the foam as a guide also. Once I was happy with the shape (checked side to side with cardboard templates) I glassed the hull with epoxy resin and 5 oz cloth. I rolled on a thick layer of resin before the cloth, to help with filling the pores of the foam. Hull had 2 further coats of resin, sanded between coats, then another 2 with fairing powder mixed rolled on, the 2 more thick fairing mixes squeegeed on, (imperfections filled as well). Each coat was sanded back to eventually hide the weave and leave a smooth surface. LOTS of sanding !-orbital sander, finishing sander, block sanding etc and some Surforming of any high spots in the resin. Next job (yesterday and today) was clamping the hull to the bench for cutting out the cockpit, (clamps go under blocks with cutouts screwed to the bench with a cross bar for the deck, and hull on foam blocks) Cockpit was cut out using a jigsaw with a short medium blade, and finished to the lines by drum sanding and blocking. The deck and 1st lamination came away as one piece, and the second lamination was cut down to with an extended snapoff knife set to the depth, and then picked out easily in large pieces due to no glue in that area. Cockpit is now 50mm deep, with a nice flat bottom, ready to either epoxy thin ply round or glass it then lay ply. The deck will be glassed eventually as well. Centerboard case top will be routed out to drop a complete case unit through, (as I did with the cat) Transom is also 5mm ply, epoxied on before glassing, (which links its' edges to the hull, otherwise it would only be a foam strength joint) Next I'll have to knife some epoxy between the laminations on the centerboard case, as they obviously had no glue previously. the whole case will be ply sheeted and braced. I'll leave painting till last, as the hull will have a lot more done to it yet ) rub rail, coamings etc) This is where it's up to at the moment,- more to follow. See pics of the full size boat, and some of the detail I hope to add to the model. Boat was built in the 80s, took me a year to restore it, (including removing a full width outboard well.) JB

Adding a Reverse to Forwards Only ESC?

Hi Bob. I've already tested this with a brushless ESC, and used the same idea for reversing one of the brushed motors in my MTB about 20yrs ago, (posted in the how to section about a year ago) You can use a 4 way toggle switch with a hole drilled in the toggle for a rod to a servo. You have a silicone tube buffer each side of the toggle on the rod, with adjustable stops behind them. You wire 2 of the 3 leads on a brushless ESC to the switch so it reverses any 2 leads. The 3rd lead bypasses the switch. ( you have to make up a few leads) The switch I used was 10A 240V and it works fine with most small to medium sized motors. You can probably run up to 1000W safely through the switch. The motor in the video is rated at 470W and nothing gets remotely warm, flat out unloaded. The important thing is not to reverse it without stopping,- motor needs to stop before switching. Fwd and Rev is 100% positive (unlike some of the cheaper ESCs with reverse.)

Re: Aerokits Sea Commander. Strange Handling ?

Hi Harry, We used to off-set the water scoop pick-up tube to the right of the prop shaft back in the days of fast ic powered model boats to counteract the torque, but I have never off-set the prop shaft. Some of my fast flexi-drive-shaft equipped flatties have an off-set rudder with the water pick-up included in the rudder blade. I also like speedway and supported the Bristol Bulldog’s, Exeter Falcons, Poole Pirates and Swindon Robins when I lived in various places in the West Country, but since moving up north our local team is Bellevue in Manchester (also the home of the National Speedway Stadium). My all time favourite rider was Ivan Maugher and our best local team captain was Phil Crump. Bob.

As Bob mentioned in another thread this model could form a good basis for a recovery boat with its blunt bow that should be quite easy to modify to form a claw of some sort and like him I'd like to have something like that in my fleet. It should also be quite easy to make the claw quickly removeable to use the model as originally intended. I don't have a lot of time at the moment but I have made a start on the drawings and they shouldn't take too long to complete. Whilst it's just the bulkheads and certain other parts that are required I always draw the plan and side elevation as well (which is where I've started) so that when printed off there is uniformity between all the parts and of course it can easily be resized as one would like and it may be a good idea to increase it in length a bit from 23" if it is used for recovery? I'll draw it as standard initially if someone wants to build it like that and then modify it for recovery and anything else that springs to mind. I'm already thinking of making the cabin and rear hatch as one piece but otherwise not straying too far away from the original design which would spoil the simplicity. Feel free to make any comments and observations and suggested changes as we go along. Chris

Re: Aerokits Sea Commander. Strange Handling ?

Regarding the cheeky comment from ChrisF suggesting that the cause of my strange handling problem was my “throttle hand”. …..I admit to driving all my classic power boats quite quickly at times (fast) as I like to see them make “white water”. However, I drive all of my Classic Model Power Boats “with enthusiasm” and enjoy seeing them perform well and in a scale like way (OK maybe slighter faster at times 🤓). As I have a variety of different Classic Model Power Boats to drive (along with some quite fast flatties etc) I appreciate that they do not all perform in the same way and drive them accordingly. However, the ONLY Classic Model Power Boat that I have driven since the 1960’s when I first started driving (and racing) them that has displayed this strange nose diving quirk has been my Sea Commander! This is not all bad news as now I have gotten used to it (and even know how to “encourage” it to perform in this way), I sometimes deliberately drive it into this situation as it looks so spectacular with the decks awash and partly submerged forcing the “wave breaker” to display its effectiveness (it does work!). Having admitted to the above, and seen other Sea Commanders behaving in exactly the same way (depending on speed and water conditions), I am not really worried about it at all……but I would still like to understand why this particular design handles so uniquely differently from any other Classic Model Power Boat that I have ever driven or experienced over the last 60 years or so of “enthusiastic” driving with the same “throttle hand”. 😎

Adding a Reverse to Forwards Only ESC?

I will give that idea some consideration RubaDub as it could save me taking a perfectly good working ESC out of a boat and replacing it with an untried and untested (as of yet) water-cooled SHARK ESC that has forwards and reverse built in. A couple of weeks ago one of my local friendly holiday camp neighbours started coming to the Southport Model Boat club with me and showed some interest in getting started with Classic Model Power Boats and over a couple of pints of our latest (strong) home brewed beer he revealed that he is an avid electronics components buyer. He also had various discount codes that he could apply to his purchases from a well known Chinese supplier. This quickly deteriorated into a competition to find the cheapest SHARK 100A ESC and I found one for £19 including delivery ! Surprisingly it has arrived safely in the post (!) so I now have one to test and my new future model boating companion also bought one (for slightly more!). Bob.

Hi EdW, Have you been able to buy lengths of silver steel over 12” long? I have quite a few boxes of 10” and 12” silver steel from my model engineering days, but longer lengths were not usually stocked by my local steel supplier. Are you going to turn your own flanged bearings from Phosphor Bronze or Brass? Lastly, do you mind letting me know how you anneal your silver steel to make it soft enough to cut a screw thread in it using High Speed steel dies? I just used to heat my silver steel until it was glowing red (on the end to be threaded) and then let it cool down slowly, but knowing which colour band to quench it at after cutting the thread and re-heating it again was always a bit of a guess for me. When I get home I may check the cost and availability of 8mm O/D brass tube and 5mm stainless steel or silver steel bar locally along with the same for brass or phosphor bronze to make some bearings from and see how the prices compare with buying a 5mm Maxi shaft ready made.

I will check the balance points of my Rapier and Sea Commander copy and compare them to those that Harry has noted here. I seldom measure the balance point of any of my Classic Model Power Boats, but I always aim to have this around two thirds to three quarters along the hull from the bows. Making small adjustments to this balance point can make a difference to the handling (see the thread :- Aerokits Sea Commander - Strange Handling notes). I will take a look and compare as although my Rapier has outstandingly good performance in rough water conditions - my Sea Commander most certainly doe not enjoy the same degree of performance these water conditions.

Hi RodC, A postal service is something that everyone wants/needs but would prefer not to pay for. In the UK less and less people are posting letters. Part of the reason for this is because fewer people can actually be bothered to write with a pen/pencil (keyboards are preferred) but the cost of posting a letter has made it less attractive. In comparison, the cost of posting a small package looks like much better value for money and our local “postie” reports carrying fewer letters every day - but many more padded envelopes and small packages that ever before. Larger packages and boxes etc are delivered by van and not by the “postie” who still uses his legs to walk his delivery route. Some suppliers (less and less) these days add unrealistic postal delivery costs to their products to make a little extra cash, but most take advantage of the very competitive delivery service that we have in the UK that has several couriers competing against each other, and this drives the prices down - or at least keeps them competitive. Some suppliers add a standard delivery charge to everything they sell. This can work out OK if you are spending and buying a lot, but penalises those of us that just want to buy small lightweight items such as a few plastic propellers or an odd prop-shaft that anyone could take to the post office and post for less (much less sometimes). Even more interesting is that anyone can arrange and pay (by mobile phone, iPad, computer etc) for their small package to be uplifted from their home at no extra cost! Being aware of this can cause a little unhappiness when a supplier adds a fixed delivery charge to small items that anyone (that does not even have a business rate deal with any particular courier) can send for less. Against that, we do have quite a good postal delivery service here in the UK, but (traditionally) we enjoy a good moan about things from time to time, so any perceived over-charge for being sent something by mail gives us a good opportunity to enjoy a good moan about it - and to share this discontent with anyone else who can be bothered to listen 🤣 Having had a bit of a moan, few of us will make the effort to escalate this to the next level and actually complain to the sender about adding unjustified costs to those small but essential little items we need …….but it doesn’t stop us either being fully aware of it - or being little “miffed” about it. From what you say, maybe you could have even more of a (justified) moan about your postal service in Canada? Bob.

Adding a Reverse to Forwards Only ESC?

Zooma.. I had a different issue, but needing the same solution.. (I have an ESC WITH a reverse function that I disabled as I don't have a reverse throttle stick position on my Transmitter!!) The attached photos show my solution. A 12v single throw, double pole relay, wired to reverse the polarity on the motor by flicking a switch on my transmitter. I now just view the throttle lever as an RPM device and the switch as the Forward/Reverse, kinda like a real cruiser! BTW, this relay is a 30amp device.. (much more than the stall current on my 800 motor!) This setup would also allow you to swap/reverse 2 of the 3 supply wires to your Brushless motor.. You might want to try a Watt meter on your setup to see what the actual peak current your motor draws.. A 150amp ESC on full load would blow the brains out of ANY mechanical switching device, in which case you SHOULD consider a Forward/Reverse Brushless ESC, providing your Transmitter will support this function on the throttle stick!!

As I've standardised on a number of components, a couple of years ago I stocked up as I thought there was a possibility that supplies might be disrupted from China at sometime. I bought enough motors and ESCs for all my existing builds that I hadn't already bought them for and estimated future builds (not that many planned after my Faireys) plus a few spares. This was also partly prompted by being caught out and not being able to get my favourite alloy motor mount when the company ceased training. I also stocked up on Hitec receivers as manufacture of these stopped (tipped off by a neighbour who also uses Hitec). Fortunately managed to get enough from dealers who still had some and from Ebay. Fortunately I've got most of the prop shafts I need as I had to buy those as I went along to incorporate in the construction. Good job given the prices now as mentioned.

Adding a Reverse to Forwards Only ESC?

HobbyKing make a lot of good ESC - many of which are used in r/c car racing (I have used them for many years). There can be quite a lot of confusion about which Chinese manufacturer makes what ESC and the marketing names that they or their distributors and sellers use to market them with, and even this can change from territory to territory. As far as I am aware Hobby Wing make most of the well known ESC that could be be branded with their own name, Quickrun, SeaKing, Leopard and Turnigy - and probably others that I have not come across yet. Another important Chinese manufacturer is Surpass who also make some excellent ESC and servos too! Surpass may well also produce other servos and ESC under other brand names for all I know. It is difficult to be 100% sure about who makes what brands these days or to know if that will remain the case in future years as brand names are re-used or sold, and some have various models made under sub-contract elsewhere as well etc. Bob.

Re: Aerokits Sea Commander. Strange Handling ?

Re latest post by Chris F. When you slow down in a real boat the bow is pushed downward by the remnants of the boat’s wake. Happens when the wake, which is now faster than the hull’s speed, catches up to the stern. The flatter the hull’s deadrise is in the stern the more the bow will be forced downward. Analogous to slow running in a following sea. Same thing happens with model boats.

I forgot to mention it at the time, but since it is still bothering me, the cost for sending the spare plastic propellers to me that I bought locally recently was £6.50.

Re: LesRo Sportsman (?) Restoration

A new 12” prop shaft will be needed to be fitted fairly early into the hull rebuild, so I need to either buy one or make one. As the hull is already built the bulkheads would make it really difficult to fit a tube that already has an oiler soldered onto it, so I will fit a plain shaft without an oiler. Most of my prop shafts have a 5mm inner shaft and have run for years (some have run for hundreds of hours) without an oiler fitted so this is not likely to be a problem on this boat - and various clamp-on oilers can be retro-fitted easily enough if I should ever feel the need to have one in the future.
