Set your low needle so you get a good idle, then you set your high needle to get the temperature you won't. With heli's you are alway's flying on the high needle not the low. Your low needle is just to get you in the air, after you are in a hover you are on the high needle.

Your TT39 should do any 3D stuff you won't to do, if it is bogging down something is not set right (throttle or pitch curves). What are you running for pitch? You don't want anymore then a +9 on the top and about a -8 on the bottom. You don't need as much pitch for inverted flying. These are just ruff numbers you will have to do your fine tuning at the field( but I haven't seen or heard of a 30 size heli pulling anymore then a +9) if you have more then a +9 it will bog.
