Align ESC 75 amp
Just finshed my 600 and took it for a hover.
The speed controller got hot after about 3 mins of hovering.
Is this normal

I have got the tt tail with the XL motor on 11th pinion(straight gears)

My throttle curve is about 65% mid point. Batterys were nice and cool and the motor was warm.
Was thinking that it might be cooler running flat out but was flying it indoors so was only in normal mode.

Have a BIG hall to hover in, but don't want to cruise around just in case the walls grad the heli

I figure the controller should only be handling 30 amps at hover...Makes me wonder how it's going to cope at 60 + Amps

Besides that, the hover was nice and stable. Can't wait to get it out side for some flying, but the weather is looking not to good this week

The speed controller is getting hot because you are running such a low % throttle. Below around 80% the speed controller will get hotter as it has to do more switching which heats the FET's up, run over 80% and preferably near 100% and the speed controller will run cooler, strange but true!Steve -Trex 700N, Trex 600N, Raptor 550E, 450SE, Mini Titan, Logo 5003D, Beam E4
