Trex 500 Tail Oscillation

drav8r · 03-08-2011, 05:11 PM

I have the BeastX on my Trex 450 sport and Trex 500. The 500 is belt driven and flies really well but has a low frequency tail oscillation at hover. Back and forth irregularly about 15 degrees. Almost like atrial fibrillation - "irregularly irregular." No tail holding problems during maneuvers or flight.
Any suggestions would be appreciated.

I see this same thing happening on both my 500's at times. 1 with beastx the other a gy 520 not a quick wag, like the tail is waving side to side most of the time both tails hold perfect in a hover but sometimes I do notice this.

maybe turn down the response time on your 520. i always had mine set to standard or slow, i think i prefered slow best. i never get that with my 520

i have only had that happen with the beast x on a widy day with the heading lock set to the highest setting, set to high and i have not noticed any thing like that, the tail holds like a rock... i am starting to think it does the tail better than the 520. but i just hate to say that cus the 520 is so awesome...

Is your heli on coumadin, whats its PT / INR ? I would say put some Cardizem in the tail grease, that may help your tail-fib.

Sorry I had to.
