Hot motor, hot ESC.

Something doesn't add up here. We tached it at 2204 @ 90% flat, no gov. But according to mr mels calc this is the result

Doesn't Mr Mels calculator only work for Kontronik ESC's, the OP's heli has a Castle in it. From memory you have to run a lot higher throttle % on Castle, or go up a pinion compared to Kontronik setups.

my first crash thread and its hijacked

Thread title says "Hot motor, hot esc"....???

It's been pretty good so far on my Yge equipped helis, and on external gov too.

I'm 100% sure its the motor kv too high. I had the same motor last year on the older straight cut gears which was fine, as soon as I went to the helical my yge kept shutting down with overtemp warnings. Changed to the lower kv ultimate and all was well.

Ventilation looks like a culprit too. Looking at the canopy it wraps pretty tight round the frame and there is no cut outs!? Airflow under that canopy will be minimal that wont help things.

I do with zero issues i might add. Running 2100 max for 4.30 mins and flying hard. Esc is mounted on the side for extra cooling though which might be what makes it work. But got the right pinion sorted and its a great set up.

That is not on a 7HV though. Gearing might be different on that to any of my helis

which gov function setting are you using? Reason I ask is I changed from SET RPM to GOV HIGH tonight and that has stopped my esc from cutting?

Interesting. I use the Vbar gov. Which i found to be much better than the Castle. Not sure of the specifics of the settings as my techy mate does my set ups

ok no worries,although it seems to have solved the problem, it doesn't hold the headspeed as well in this mode so if I cant sort that I have a phase sensor so might give the v bar gov a try

I would if i were you Much more accurate and generally performs better overall than the Castle. Huge improvement for the six or seven quid the sensor will cost you... if you can find one. Fast Lad stock them now though..... Just noticed you said you have one happy days Get it fitted
