Strange vibration and pinion slippage...

[harryo]

Patrick,

About a few months ago, I decided to get a Razor 2500a and a CC Phoenix 25. Since then, I've had to return the Razor twice because the pinion slipped on the shaft.

At first, I thought it was the motor, so did Matthew at Razor. But then I remembered similar issue my friend Neil Morse was having with his Hacker B20-15L and a Phoenix 25. He was having insane amounts of vibration and the pinion slippage. after a few months of emails, fixes, trial and error, he narrowed it down to his Phoenix 25 when he replaced the one he was using with another borrowed from a friend. No more vibration. Problem solved.

I just got my motor back from Razor for the second time. Fixed from the same ailment. I spent quite a bit of time thinking about this issue when it dawned on me that it could very easily be the esc. I hooked it up my test stand and noticed the vibration/jack-hammering effect, even at full throttle. So I shut it down - and here I sit. Aside from the vibration, I also get quite a loud growling from the motor at low throttle. which, I think could exacerbating the 'jack-hammering' at the pinion joint to the motor shaft. Could there be a bad chip on the board? It's happened before with a brand new Phoenix 10 I purchased.

So, the mere 20 bucks I've spent shipping the motor back and forth is not a big deal. I just want to fly. It's been going on for a few weeks now and it's getting frustrating.

What should I do? send the esc back to you Patrick?

cheers,

Harry,

Contact Shawn here at the office -- we can send you out an advance replacement to see if it helps the problem. I can't guarantee that a new controller will fix the pinion slipping problem, but we can give it a try.

Whatever the problem is, they just want to get you back up in the AIR!!!!

Shawn is sending me an advanced replacement today. We spoke at length about possible issues. Very knowledegable. I will post the solution ASAP.

Thanks Shawn and Patrick!

Well,

I recieved the new Phoenix 25 a day after Shawn said he'd send it. :D

Hat's off to you folks at CC. You can bet I'll be telling everyone I speak to about your exceptional service.

The motor spins up great, however, there seems to still be a whining noise at certain times, like when the bearing are about to go on an electric drill. Particularly when I go from full to low throttle. (100% -> 5%). I am initiallizing the throttle range after I arm it, as per Shawns instructions. Off to full throttle for a second. Other than that, I think it's okay.

I still would like to try the same arming test on the old controller to see if that was causing the vibration. (Shawn suggested taht I check the full range after arming every time. I wasn't doing that. )

I'll post my findings ASAP.

If the old esc is good I'll either send it back or send you a check, I guess.

thanks Shawn and Patrick!
