If brushed motors are the food of choice for a while, if you haven't already, look into the V2 modified motors by Orion and Peak. The cylindrical brushes coming down at an angle are very easy on the comm, and you can go a lonnnng time between comm cuts with those motors.
all of the mod motors have 2-3 runs on them
Eventually the commutator gets scored and burnt, and performance falls off. You can buy a comm stick, which cleans the surface of the commutator, but eventually the comm will wear and it'll need to be cut. Cutting down a big pencil eraser into strips, and using that to clean the comm will work ok too, but it's only a temporary fix.
I'm guessing you've never dumped it in rotor first trying an inverted hover?
When I crash, I usually dump it into the ground doing something stupid that I shouldn't be trying! Ha!
Dude, make use of some of that stuff and come race with us!! :drive1:
Remember, I said "trying" !! Ha Ha! :kooch2: I can do it all day long on a sim, but there's just something about doing it in real life that's a struggle...heli's are a test of a person's persistance, that's for sure!
Get one of those big beefy RPM bumpers. They may look a bit janky, but they're only a couple of bucks and they'll keep you from crunching those a-arms as easily. I think that big frankensteined brush guard I had was the only thing that kept me from mashing mine up right before you did...
