Model Forum / Radio Controlled / Helicopters / October 2006TRex Pitching to front left
Hey, need some advice from some of you experienced flyers. I have a T-Rex 450SE and on lift off it want to pitch to the front left (i.e. front left last off the ground) in a very pronounced way. Blades are balanced and tracking good. Any advice for what to do for a symetrical lift off would be greatly appreciated. thanks in advance...... > Hey, need some advice from some of you experienced flyers. > [quoted text clipped - 7 lines] > > thanks in advance...... Is your SWASH plate level? If it is, sounds like your trim needs to be tweaked... Elevator back and aileron right... >Hey, need some advice from some of you experienced flyers. > [quoted text clipped - 7 lines] > >thanks in advance...... Make sure that at half stick, (unplug the motor before you do this...) all your servo arms are at 90 degrees to the servo cases (parallel with the top of the frame) and your swash plate is level front to back and side to side. Once ya get it level, make all your mixing arms level by tweaking the linkages. Blade pitch should be 0 degrees. Now you'll need to mess with your swash AFRs and endpoints to make sure everything is moving correctly. The swash should not tilt when you increase/decrease collective. If it does, you've got to tweak the radio setup to get rid of the tilt. If your head is setup properly, not binding in any way and you're still having problems, make sure the helicopter is balanced properly. Check out the 450 setup videos at http://www.helifreak.com/viewtopic.php?t=12455 in Finless Bob's Helifreak tech Room. The two videos on CCPM setup apply to all models, not just the 450SE. Hey thanks, I think it was the endpoints. Your post was really helpful and saved me a lot of time. >> Hey, need some advice from some of you experienced flyers. >> [quoted text clipped - 28 lines] > Helifreak tech Room.
