@stevesb Thanks for the recommendation Steve, they are one of the ESCs on my eBay watch list / Banggood wishlist.
I’m finishing a 3D printed Inspire clone that I obtained part built. For a large UAV there is surprisingly little space in either the real thing or in the clone. The clone uses the battery space for a PDB - the raising mechanism servo draws a fair current I think. So I was thinking of a 4 in 1 ESC in the same space with long power leads going inside the tubes to the motors.
The Little Bee may fit in the tubes to keep things neat but I would worry about cooling.
@notveryprettyboy I looked at the Spedix IS40 40A 4in1 ESC (3-6S) (20mm) and the specs said:
The Joshua Bardwell 30A 4 in 1 doesn’t mention size other than ideal for freestyle or racing drones
This one seems a bit of overkill but it gives me the opportunity to up rate the motors if I find performance with 4 x 4114s too sluggish. The solder pads could also be placed in the tubes close to the motors with bullet connectors directly soldered although I think it safest to keep the number of joints, whether mechanical or solder, to a minimum.
All advice gratefully received as my only experience with ESCs is the full size things that cable-tie to the arms of hexacopters/
