Brushless motors (again)
Boat was designed for 5cc = .32 = 640W = 58A Bought the watt meter. Both the motors mentioned above are back order.

Any specific reason you refer to a 'car' ESC? What size (dia.) shaft should I use? Will I need to cool that motor? Cheers Steve

Brushless motors (again)
Hi Steve I started with the Hobbyking 3639-1100 kv in my Huntsman with a 2 blade 40mm prop, 3S 5800mah Lipo and a car 60 Amp ESC. Upgraded to the 100Amp car ESC and a straight change over to the 3648-1450 motor. All from Hobbyking. Good uni …

Charlie. Have recently been through this challenge with my 37” Brave Borderer. My blog on this site may not give all the answers, but it might save you making the mistakes I did Rowen

Brushless outboard...
Hi Westquay I had the F1 outboard from Hobbyking which had a 28mm 3000kv motor. I ran it on 3S with a 45Amp ESC. Great unit, but, clean and regrease after each days running. Also they did not have spare flex drives. The flex drives do not l …

As Doug suggests, a new topic for this. The Motor is a 2845 of 2600Kv. I have no idea what the shaft diameter is so may have an adaptor to turn there. The guys what makes the rules for 152VO say 2 or 3 S, but there is a formula that takes i …

OK. I found the specs for a similar motor, a 2850-2650 2 pole in-runner. Max continuous load current is given as 31A, Max short term (60 seconds) current 40A. Therefore you will need an ESC capable of handling 50 to 60A continuously. And pu …

Hmm! A 'Pig in a Poke'? Do you at least know who made it / sells it and what the model number is?

Oh, Gawd knows, mate! Doesn't say on the advert. And no, I ain't buying a watt meter! Got enough stuff I don't know how to use. Maybe it'll say on a bit of paper when it turns up? Martin

But what are the specs Martin? Esp. stall current, max running current and current at max efficiency? That's what defines the ESC you need. Doug

BRUSHLESS ESC
Thanks Doug. Agree with your suggestions. Have already implemented the multiple fuse idea. Hope to try it soon Rowen

BRUSHLESS ESC
Hi Rowen, that's what often gets overlooked and why the Main fuse is so essential! Good luck with the set up With multiple screws put a fuse in each ESC supply then if one screw blocks and the fuse blows everything else should still work so …

BRUSHLESS ESC
Thanks for the advise. Think if my latest set burns out, will increase ratings substantially. The point about stall current is relevant, suspect that is why one of my last ones burnt out.
Forum
BRUSHLESS ESC
Also check the STALL current of your motor! If the prop gets blocked the current drawn from a LiPo can rise so much it melts the motor and ESC if it can't withstand very high current. Worst case - you have a boatfire instead of a Fireboat! …

BRUSHLESS ESC
Hi RHBaker If the ESC exceeds the motor draw that's all is required. I only use two sizes in my boats, a 45A for small boats and 100A for the larger boats. The both use the same program card !!! These are the Hobbyking car ESCs because they …

if you use a "y" lead to couple 2 ESCs ( or if you use 2 different channels) make sure you remove one of the red signal leads from the ESC that way you do not risk you receiver ( this presumes your ESC(s) have BEC)
