Ok so this is going to be a long saga, not sure if this will ever compete or even go anywhere but I want to have some fun building crap so here goes.

So the first thing to do is make a test platform. One that can withstand a crap load of G's.
This did not go well...

test one:



test 2, even better destruction!



I've got no clue how fast its spinning, but WOW. that g force is amazing. It tears itself apart with ease! It took me just an hour to build it though

I'd say you were up to at least 3k RPM's before it killed itself. looks like you need more knurled locknuts holding that collar in place i'd say 6 should about do it.

Whole lot of progress today! made a new test platform, it spins great. Got it driving and translating too!

It has some problems though, the ESC keeps cutting out erratically. Not sure why but I tried two escs and they both had problems. One was worse than the other though.

Videos soon...

any ideas?

Are you using a new battery that you haven't tested before? The li-ion we have did the same thing until we discovered the there was a surge protector chip inside that need removed, before it would allow a full spin up.

I'm using a 2s Lipo, I don't think it has any circuit protection built in. However the issue may have something to do with power, maybe I will try powering the electronics with a separate battery. Either that is the issue or it has something to do with the ESC not understanding the weird PWM signal.

Another option since I'm assuming you're using a bec would be to toss a capacitor across the battery port on the rx to level out the voltage should you get sag from high current draw. I've used these before to help with that- http://www.robotmarketplace.com/products/0-SPM1600.html
