Aerokits Patrol Torpedo Boat by RNinMunich Fleet Admiral!   Posted: 23 hours ago
Glad to help Peter, I was a Brushless & LiPo newbie last year, guys like Canabus, Dave_M and co helped me make the quantum leap. Being a retired electronics engineer helped as well 😉 Know what you mean about 'a change now and again'! Did I mention that renovations / upgrades are often more awkward and time consuming than a new build? 🤔 I have a few other 'odds n ends' on the go for a break from the Sea Scout renovation. A Deans Marine HMS Manxman, an Alexander Engel GmbH AKULA II sub, and a Dynam PBY Catalina kit are queued up in the planning and research stages. Kit boxes are clogging up the cellar! Bits and pieces for various 1/350 Plastic Magic projects are being collected and prepared! It's all Go folks😊 Happy hunting at CMB, longish drive for me 🤔 Cheers Doug 😎

Thanks Doug. That really helps me. I have read a lot about LiPo batteries and now have a better understanding. This experienced help is perfect. I did buy the 100A car ESC as recommended by Canabus but Hobbyking did not have the suitable programmer. I have left a message so they will respond when a new supply arrives. I have looked elsewhere for the programmer but all of the stockists I found do not have any stock. Supply problem? Thanks again for all of your help. A lot of sanding down and painting awaits me for the next few weeks. I plan to drive to Cornwall Model Boats this weekend to see how it looks. I am getting that hollow feeling that I should get a new kit to run alongside this rebuild. Just for a change now and again you understand😁. We will see. Peter.😊

PS re Monitor! There are separate 'Alarm' devices (i.e. Monitor) on the market for warning you if the Lipo is approaching the critical low voltage; 3.0 - 3.2V. Look on the sites selling batteries, they usually have the Monitors as well. Some can allegedly be coupled to the feedback telemetry to warn you on the TX display, but i ain't tried that yet 😉 LiPo Safe ESCs can also be programmed to slow down or Stop when the voltage is low. This is (to me) about the only reason to buy a programming card for the ESC. Everything else; stick positions for Full Ahead, Full Astern and All Stop you can do with the TX! 😎 PPS: Before Canabus jumps on me about programming cards! 😲 There is one other reason they can be useful: If you have a Car Escape as Canabus recommends! I discovered that they are usually delivered set up to 'Brake on reverse', which means that you have to shove the gas stick backwards twice to engage reverse. Otherwise it just STOPS!! The programming card enables resetting this to 'Boat Mode' so that the motors reverse immediately you pull the stick back. If you use Marine ESCs this isn't a problem as there ain't no Brake!

Hi MB, can only say what I have which works and I ain't set the house on fire yet 😉 Not surprisingly for someone living in Munich both mine are from German companies! Robbe Power peak Uni 7 and Graupner Unimat 14. There are later versions of both around nowadays but you can still find these on Amazon / Ebay etc. Both of them have automated programmes for various Lithium types, NiMH / NiCad (not recommended these days!) and SLAs. Robbe is now defunct and their Marine stuff taken over by Graupner and marketed as RoMarin! Pics also show the Balancer Adaptor Boards, necessary to connect the balancer cable of the battery. This ensures that each cell is equally charged 😊 I also included in the pics the little battery Capacity Testers I use. They cost around a tenner and are very useful for checking the capacity before a run or charging, as well as the voltage and capacity of each cell, which gives an indication of the battery condition. I found some duff cells with the tester in a few batteries I'd only just bought 😡 When looking for / buying a charger look also for a LiPo Safe bag to charge them in. E.g. LiPo Guard. Charger may cost 50 quid upwards depending on how many charging outlets you want and how many Bells & Whistles. But I get on well with these two 😉 I like the Robbe version cos I can charge two LiPos at the same time. Also in the pics are a few of the charging cables I made up with gold 4mm bullet plugs for the charger end and Tamiya and BEC (for my Plastic magic stuff!) at the batt end. Such adaptor cables are also available 'ready made' but I just like fiddlin' 😊 Hope this helps, Cheers Doug 😎 Nearly forgot! Can't say for sure what current your motor will draw cos I don't know all the other details, but a 40" boat will need some shove! So I wouldn't go below the 5000mAH if you want a half decent run time. A 40" boat can carry a bit of weight! And batt power is more useful than pure ballast 😉 Recommend a little Wattmeter to check the max current draw - see last pic. Basic theory! A fully charged 5000mAh (or 5AH) batt can theoretically deliver 5A for one hour, or 10A for half an hour and so on! Say your set up draws 20A with the 'pedal to the metal' then a 5000mAH batt will 'theoretically' last 15 minutes. Theoretically cos other factors are in play; initial charge state, temperature, internal resistance of the cells, cable losses etc. The latter is why I only use gold connectors! The higher the batt capacity the higher the price and weight. So suggest you start with the 5000 and see how (long) it goes. Then check the weights of higher capacity batts (and the bank account / management approval😉) Bon chance mon ami!

Hi MB, don't recommend you use ANY kind of batteries in parallel, esp. LiPos, unless you have a connection / distribution board in between that will stop one battery trying to charge the other. This will happen if the two batteries do not have identical charge levels! Component shop have such a board (from Action Electronics) to do this. Also, you will probably find that, for example, 2 x 2500mAH batts will weigh more than one 5000mAH batt🤔 and be more expensive. Only advantage I can see in using two instead of one is that you can put them either side of the keel to help reduce any rolling tendency. Effect is minimal I think though. Cheers Doug 😎 PS: One per ESC and Motor as Jarvo is doing - Fine. Two in parallel feeding one ESC - not so fine! 😉

Hi Mate, there was an offer on ebay £5 each for 2200mah 3s lipo's, so i took the plunge, bought 8 of the beasts, 2x2 in my Fireboat, with twin 700BB motors, thinking of swapping to brushless but SWIMBO has ideas for the garden!!!! Mark

Aerokits Patrol Torpedo Boat by MouldBuilder Sub-Lieutenant   Posted: 2 days ago
Thanks Mark. Is there an advantage in using two 2200mAh batteries in parallel instead of one 5000mAh or is it price. Do you have any views regarding a particular charger. I have never used LiPo batteries before and I read they can be problematic if not used correctly.😊

Aerokits Patrol Torpedo Boat by jarvo Fleet Admiral!   Posted: 3 days ago
Hi MB, the motor you have would go well on 3S lipo's, as to the Ah rating, cheepish 2200mah in parallel is the way i went using a Y lead, others may say go for larger capacity !!! your choice. Mark

Aerokits Patrol Torpedo Boat by MouldBuilder Sub-Lieutenant   Posted: 3 days ago
Hello. I hope I can get a little help with battery choice. I have been reading the comments above and elsewhere on the site, and have decided to go along the LiPo route. I purchased the Turnigy 3648 1450kv brushless motor along with the Hobbyking brushless car ESC 100A w/reverse. I have done a little research on this battery but still do not know the exact battery I should be looking for. Please can you help with the following: What voltage should I be looking for. To have a reasonable useage period, can you advise on a suitable mAh rating. Please can you recommend a charger. Should I have a charge alarm. Should I have a monitor for cell voltage. Are there any other accessories I should have. Thanks in advance. Peter.😊

Hi Biggles. I am at a very similar level to you. I am seeking help from the kind members so that I can improve my skills. I built this boat in 1993, which by the way, I had no idea about until I removed one of the life rafts to find I had painted the completion date on the bottom. I am currently stripping the paint and trying to get advice on the painting method. At present I am tending to favour air brushing Revell aqua paint but I am open to other views. As for the spray rail, my boat has never gone fast enough to need them. To be clear, is this the rail around the joint between the hull and deck which my boat has. Told you I was a beginner as well. With the more powerful motor, anything that keeps water from the electrics must be good. The gun was supplied by Battlecraft in Bideford. It is in 1:24 scale. I have just purchased a 40mm Bofors for the stern. Nothing like a lot of weapons. Perhaps I should have some torpedoes one day.😁 I have just bought a 3648 1450kv motor from Hobbyking for mine. I am advised that this will sort out my slow speed problem. I have also been advised to fit Lipo batteries. I probably will once I get over the thought of a large fireball on the river or in my house during charging.😉 Would love to hear how the renovation goes. I am considering starting a build blog as it might be a good source of gaining extra knowledge. I am not sure if a restoration will be ok on the build blog so I would appreciate if a member in the know could comment on this. Work keeps getting in the way of my plans but one day!! Peter.😊

I have an Aerokits Fast Patrol Boat, what scale 20mm deck gun did you buy is it 1/24? Also I was thinking of powering mine with a Graupner 700BB Turbo motor and Nicad battery packs or Lipo batteries. My hull doesn't have spray rails, should I fit some? Sorry for all the questions but I'm returning to powered model boats after a long absence! Thank you for any help received.

Superstructure by RNinMunich Fleet Admiral!   Posted: 4 days ago
Plasticard! 😲 That's cheating 😁 but I can more than appreciate why, being in the middle of renovating a 60s built wooden boat! I also separated the bridge and deck houses on my destroyer to hide various switches and sockets👍 BTW: if you're using LiPos DON'T CHARGE THEM IN THE BOAT PLEASE!!!😡 Charge 'em in a LiPo Safe bag! Cheers Doug 😎

Vivace Patrolboat by Tica Lieutenant   Posted: 5 days ago
Started on a new "in between" model boat Vivace drawn by Glynn Guest. I'll use a Chinese jet drive as designed by GG but with a minor modification 😁 Which is a BL Turnigy 3800KV 2627 running on 2S LiPo. (as I also did on my NQD Tear Into Pro Mod.)

more progress. by Skydive130 Fleet Admiral!   Posted: 8 days ago
First job today was to reduce the rudders by 1cmx1cm which I think not only looks better but should reduce the affects that have been mentioned in comments below. Ive fitted the cockpit which I assembled yesterday. Its not the best fit into the deck, however, I shall blend it all in with some balsa strip, sand, filler, sanding sealer hopefully for a seamless finish. I have pictured the 2 x Hobbyking waterproof boat 30 amp esc. These are supposed to be water cooled, however I am not going to fit the tubing and start drilling water pickup and exit holes in the hull x 4 until I think that water cooling is going to be necessary. Once I have watt meter readings for 2S and 3S lipo, it will give me an idea what the ESC are going to be like. Of course if you guys think I need to go water cooling, please let me know! I have an Mtroniks W-tail mixer that will allow the motors to be synched to the rudders allowing the inboard motor to slow or stop when turning. Never used one before, so may need to some programming once hooked up, we shall see. Last job today was to shoot a could of coats of red oxide primer on the lower hull to see what the resin finish was like. on the whole not a bad finish at all, just a could of tiny areas that need a little sanding for a faily blemish free finish.

Devil in the detail! by RNinMunich Fleet Admiral!   Posted: 8 days ago
PS: to assist the steering you could use this dual ESC and rudder mixer combi, BUT only with brushed motors! More than adequate for a Lifeboat! Just an idea, ciao Doug 😎
