Hi

I have a Raptor 30 whose tail is very erratic and I need some help! I simultaneously upgraded the following:

1. Installed header tank
2. Carbon boom supports
3. Rear mounted tail servo
4. Faster tail servo
5. Home made ali cooling duct extension

After doing the above I cannot achieve a stable hover as the tail will flick one way and then the other, sometimes quickly othertimes its more of a drift. I have reversed the above so all I am left with is the carbon boom supports and rear mounted servo, but still the problem persists.

The gyro is a simple piezo affair mounted at the fron near the receiver. In order to reverse its sense for the new servo I had to remount rotated 180 degrees. I had to use dinew mounting tape and my question is: does the kind of mounting tape have a big bearing on how this kind of gyro acts? Is it important to use exactly the same type as was supplied?

Please shed some light as this is driving me crazy!
