3 brushless motors on one channel ?
Hi JB, "probably could use just one battery on a power distribution board, that's all they do with drones which commonly have 3-8 motors/ESC" Yeees, you probably could, as long as you're not looking for exorbitant current, like some of the …

3 brushless motors on one channel ?
Hi CB, The absolute easiest way to do this, unless you like experimenting with electrics and wiring, has to be to use the P40E motor and rudder mixer board for up to 3 motors from Action Electronics. https://www.componentshop.co.uk/p40e-mar …

Brushless motor couling
Hi Steve, The inserts of the spiral coupling are not threaded. They are secured with grub screws. That's why I milled depressions in the shaft to prevent any slippage. See my 2nd pic below with the shaft and coupling on the mini milling mac …

Homebrew universal brushless motor programming card
This project came about as I often wondered what the output from a programming card was - could not be any different to the output of a radio receiver which can be used to achieve the same results. The other aspect is that they always seem …

BRAVE BORDERER - BRUSHLESS SUMMARY
The only thing you might have to watch out for is back feed from the pump out the aux tube (when moving) if you don't set up the y joints (must be y not T ) to create a venturi effect from the pump side. Doesn't matter standing still but at …

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! …
