46" Firefloat What Motor/Battery by pmdevlin Fleet Admiral!   Posted: 27 days ago
Hi John, you might now be scratching your head, and wishing you have not asked the original question! This seems to be a common issue, as the boating community is light years behind the other disciplines, rc cars, planes helis and so on, its probably due to the facts general boating doesnt really need the later generation technology, the average boater age is probably higher than the other disciplines so budgeting might be an issue, and there is less younger blood in the clubs to explain the lipo/brushless etc. We see posts with a load of numbers, specs, warnings etc, its enough to put people off. Im a big fan of brushless/lipo/ 2.4 etc, been doing it for years, its cheaper and more efficient (once you have the basics) but for the average guy, who just wants to spend an easy afternoon at the local lake gently cruising around, brushed motors, nimhs batteries, even lead acid, will do the job👍 Your 4 foot ply boat, once painted, with fittings, will be heavy, I know, I own one. Those 600 motors are not big enough, they are better suited to the smaller 3 foot boat, then, pushing them with a 6v lead acid, just cant do it. The battery will be screaming HELP!! I started 15 years back exactly the same, 600 motor, 6v battery, massive 50mm prop, I knew no better and took advise from people who didnt know what they were talking about😡, remember those gold hi tech speed controllers!! I had one, it melted, literally melted on the first use😭 Get 700 size motors, they will need to be water cooled, as mentioned by jarvo, the nominal voltage or below isnt good enough, power them at the max voltage. Brushed means you can use one apropriate esc, look out for electronize (are they still in existance?) or mtroniks, preferably use nimhs batteries over lead acid with a high mah. If after all this you want to venture into lipos and brushless motors, go to a club, spot a boat that is similar in size to yours, if you like the performance talk to the owner and gain experience and knowledge that way, it will save money, lost time and a lot of disappointment, I have been there so feel your pain. I say I would never go back to brushed motors and none lipo batteries, but I always want silly speed, not runtime, after 15 minutes Ive had enough and am bored. Rambling over! My 4 foot boat is twin brushless and uses 4 lipo 5000mah cells per motor, it will do 25mph for 15 mins, then I go home😁 Message is, you can get a "reasonable" performance from brushed motors, with the correct batteries, right props, but weight is the enemy. Looks lie you are at Biddulph, get onto Dave M a moderator on here, and arrange to go over to see the crewe and district boys on one of their sailing days, take your boat with you, they will help👍

Brushless motors by Spitfire99 Commander   Posted: 1 month ago
Thanks Dave I'm very new to this brushless world and not quite sure what a ESC or BEC is yet. Is one of them a speed controller. I think I'm being a bit thick here and do not want to cut or remove the wrong red wire. As there a few. May have to send you guys a photo

Seuthe Smoke Generator by Ballast Captain   Posted: 1 month ago
It's the rookie again !!! Can anyone please run through how to fit a Seuthe Smoke Generator please ? I want it to have it's own switch. I am going to be running my Puffer with an electric motor through a speed controller off of a 6V lead battery. Does it have to have it's own separate battery or can I run it off the system ? Help will be appreciated !!!😱

Aerokits fire boat 35" by Flack Admiral   Posted: 1 month ago
Hi Kevin, I have had a lot of success with Tornado Thumper out runner motors paired with Fusion Hawk ESC. For a really exciting performance you could use a Tornado Thumper V3 4260/06 500KV - Brushless Outrunner paired with a Fusion Hawk BL 60A HV N6~18/Li 2~6 ESC, however it would probably be a little less exciting and more appropriate given the flatness of the hull when the Crash tender is on the plane to use a Tornado Thumper V3 3542/05 1250KV - Brushless Outrunner paired with the same speed controller. Motors are available at and the speed controllers at: I appreciate they are not the cheapest of options but I have found their reliability to be second to none. Shaun

Steam sound unit (variable speed) by EricMB Commander   Posted: 2 months ago
Thanks Doug, I’d had a recommendation for these already, although their site mentions that they only work with their speed controllers... I may give them a try though. I’d really like to find one that has a sampled sound (for realism) rather than synthesised but bit found one so far! All the best to you too.. Eric

Steam sound unit (variable speed) by EricMB Commander   Posted: 2 months ago
Hi all, I may have missed a post on this subject but would like some advice on the best steam sound unit to use with my electric-powered Imara! I’d like it to be variable to connect with the speed controller, although this may be a challenge as it’s running two ESCs for the twin props.. Any help gratefully received. Rgds Eric

hi i have a wooden huntsman 46 ready for motor my last post gave me some ideas i am looking at hobbyking turnigy xk3674 1900kv part number 9393000021-0 and turnigy marine 120a bec waterproof speed controller part number 9020000033-0 what do we think steve

850 Brushless by BOATSHED Admiral   Posted: 2 months ago
Hi canabus, could you please tell me what brushless motor's you have in your, Sea Hornet,Sea Commander and Sea Queen pelese. I have all three of these as well. Somewhere down the line I will be converting those to brushless. I don't understand all the electrical data myself. I do have a Proboat Miss Geico and she is awesome on the water at full speed. I have purchased the same motor and speed controller as what is in her to put in a new MFA Spearfish that I still have on the shelf in my work shed. I look forward to your set up's.

Happy Hunter by spitfiresooty Chief Petty Officer   Posted: 3 months ago
hi -the hull only had these two motors and gearboxes in .I have greased the gearboxes cleaned the motors and soldered the wires on .The casings of the motors were rusty and have just been painted with a rust killer type paint..There is a bow thruster fitted with no motor but this locks up after about half a turn of the drive shaft -looks like I will need to replace this.I have bought 2 Chinese speed controllers with max current rating of 250amps ( waterproof type) I have used these before and seem ok but my experience is limited..The intention was to drive the motors separately on 2 channels

MFA Piranha by BOATSHED Admiral   Posted: 3 months ago
I have a MFA Piranha almost finished in my shed and a MFA Spearfish I purchased from a model shop in Cromer. That shut down not long after I purchased it. That's still in the box as new. I intend at some point to put in a brushless motor. I have one already. I got both Motor and Speed controller the same as in the ProBoat 29" Blackjack. I already have the ProBoat Miss Geico that is a maniac on the water. So I'm hoping once I do the Spearfish that will also be awesome.

Voltage step down by Novagsi0 Captain   Posted: 3 months ago
Just a thought- The component shop does do a voltage reducer rated at 6 Amps power draw, and will drop from DC (10.5-40v to 1-9v) I thought about using one of these to run a 6v volt Marx Hectoperm motor from a 12v source, to save buying a new battery. As long as your motor speed controller setup doesn't draw more than say 4~4.5 Amps. I'm my case the tug had 4 x 6Ahr 6v batteries wired in parallel giving 16Ahr and 2-1/2 hours running time @full speed. These batteries have since all died due to age. I wanted to use just 1 x 20Ahr 12v battery instead and keep the added ballast I need anyway. This 6 amp unit is on the limit in my application. P.S i'm tight with money and I acquired the battery free from an alarm battery swap.

rotating radars off mast by seafarer Chief Petty Officer   Posted: 3 months ago
Thanks Dave, you've set me off on another adventure into the unknown but I think I'm I need the Arduino UNO controller and could I control two motors off it (it doesn't matter if the speed is the same ) . If I don't need the controller ,could you explain a bit more about using the POT (presumably a potentiometer?)

Motor problem by Haverlock Fleet Admiral!   Posted: 3 months ago
I had a quick look around and discovered this hull matched 12V 750 Speed electric motor, hull matched 40mm 2 bladed prop this from However if you want performance That should give the equivalent power output to a .40 IC engine and make the hull come to life the way it was intended to. Couple that to a LIPO battery and a suitable ESC. Remember when the kit was originally made IC was the norm The Sea Commander was introduced by Aerokits at Gorleston Norfolk in the early 1950s. Designed by L J Rowell the Sea Commander is a smaller version of the Sea Queen. The length is 34 1/4 inches by 10 3/4 inches and is almost identical except there is no mast. Intended for the ED Marine Racer and Hunter power plants

Motor problem by RichardSReade Sub-Lieutenant   Posted: 3 months ago
reading my previous post I got it wrong the heavier weight is noe in the compartment behind the motor with the lighter one forward of the motor compartment, The prop is a three bladed brass one so difficult to measure the diameter when on the boat, but each blade from the center is just 30mm, the power box is an Aquapower digital speed controller model AQP128. The prop shaft spins freely Will be retiring to bed now so will check any replies tomorrow, thank you all for the help and advice

Motor problem by scout13 Chief Petty Officer   Posted: 3 months ago
how have you got the batteries connected each pack is 7*2v have you wired them so it is putting to much power to the motor also looks as though you have covered up all the air vents to the motor also try a fuse in the system it saves blowing up speed controllers hope this helps
