Tail wag fixed.

[Wesso47]

So I bought the sr from my local hobby guy and installed the esc from the sr and it works, and works food. Needed son tuning but tail wag is gone.e

I had bought an old record player and I mounted the sr on it and taped it down. Works great as a bench top tail rotor adjuster, almost as well as hovering but you don't have to worry about crashing.

Thanks to the couple of people who made suggestions on what to check to fix problem. I'm still going to build a t-rex 250 but now my sr has a chance.
