Can't control my rex
I was able to hover my T-Rex 450 XL HDE pretty good, than had a crash into the fish tank (LOL). I replaced a broken tail housing and rudder blades. While waiting on parts I replaced the servos that came with the dx-6 for Hitec 65's. When I throttle up my heli want to immediately flip over to the left. If I didn't have on trianing gear it would have crashed. I checked over everythings made some adjustments and it still want to tip over to the left. I can even make adjustment on my tx and it still wants to tip.

RE: Can't control my rex
Let me ask a few questions.
1. Unplug the motor and raise throttle stick. Look and see if the swash is level during the full travel. Is it level?
a. Low stick
b. Mid stick
c. High Stick
2. Did you ensure your servos arm are at 90 degrees at Mid Stick? Subtrim can help with this if you can't do it mechanically.
3. Did you reset all trims and subtrims to zero when you installed the new servos?
4. My first question should have been is this CCPM or Mechanical Mixing?
