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!
That's good to hear.
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.
I could be wrong, but that motor might be a little light for the Axe. I've heard that it was really designed for the Blade which weighs considerably less.
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!
Cool isn't it. Spin down was really cool after a I swapped in an MX400 main gear.
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.
Do you have hover pitch adjustment. It makes dialing it in a snap. I have mine set to hover just above half stick too so the throttle can trigger the timer.
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.
I programmed one of my mixes to max offset and attached it to my throttle hold switch. So basically when I flip the throttle hold it not only prevents the main motor from coming on, but the offset mix simulates full left rudder so the tail motor stays off too. It makes it alot easier to carry around and mess with the canopy and battery. I love my 7C. [&:]
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.
My Axe's tail bouces a bit sometimes, but it doesn't really wag. I'd try reducing the gain. Right now my 240 gain setting is a bit below 50% and that seems to be the sweet spot on my bird.
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.
You can never have too many heat sinks. Cool Runnings.
