The pitch slider is actually the same as the one on the T-REX XL, and it does the job just fine. The only differece is that it will not slide from end to end but this is also ok because if it could reach the left end of the shaft you would have over 20 degrees of pitch. As it is the tail will spin faster than you would ever need at max throw.

When I reach home tomorrow I will post my radio settings, I also wanted to post a vid of the way I have my radio setup to get the gyro working properly. I ran into a problem were the gyro would somehow always return to max endpoint when i switched from rate mode (which I had trimmed center and placed the servo arm on 90 degrees from the servo body) back to HH mode. I had to add something like 70% subtrim on channel 4 to keep the gyro from drifting either to the left or right when in HH mode. Once this was done the tail finally held in HH mode like it was suppose to. Also this effect happened on 2 seperate HM 400 gyros and using two seperate radio's (JR X9303 and Futaba 6ch Fasst).
