Markind glad to hear you got her up and running. The motor temps concern me though. I'm curious what was the ambient temp at the clubhouse when you flew?
I've read that 180º is the point where the motor starts to break down so be careful. The other thing is the tail motor. My tail ran at 98º with the geared tail and about 130º with DD so your tail is a bit on the hot side as well.
Brother Heliko! Yep up and running again, and I made more progress this morning!
I did two 4-minute hovers after tweakin' up the Normal Pitch Curve and smoothing down the Normal Throttle Curve.
The LiPo barely got warm. I'll guess peak at 110 deg. F. It measured 11.2V after the tests. Great!
The Tail Motor and both ESCs barely got warm. Again, maybe 110 deg. F. peak. Great!
The Main Motor maybe, just maybe peaked at around 178 deg. F. Actually, that's not completely insane. I will probably hack in some more heat sinkage, and all should be well. Could be also I can sneak the Pitch Curve up a bit more and drop the Throttle Curve.
SMOOTH!!! I can tell too that when she spins down after landing, the main rotor takes a lot longer to come to a stop. Great! Less friction! Looks more cool! She was smooth enough I could sneak a look down at my radio - hovering at exactly half stick! Cool, but it needs to be a little above that point.
I am still putting up with the Tail Motor not spinning down. Its not so bad if I peg the Left Rudder Trim all the way over after landing - the tail still spins but slowly. I can then remove the canopy and disconnect the LiPo pretty safely.
The tail wags badly on sudden changes to Collective / Throttle. This could be because the brushless motor can not change RPM fast enough with that tail gear in there.
A few more tests, and probably I will configure the tail for Direct Drive. If the tail motor gets too hot, I can add more heat sinkage.
It never ends... [sm=angry.gif]
