Ok, which trimming tabs do what?
When my heli gets off the ground and start to tip backwards should I adjust the bottom or side trim tabs. And to what direction?
When it starts going to the left ( not spinning but heading in thta direction) which tabs should I adjust and to what direction?
Thanks
Your question assumes averything came correct from the factory. Mine didn't. For what I paid, I didn't expect otherwise. If you're paying for a Ford, you're not going to get a Lincoln.
Here's an easy way to figure out what's what. Disconnect your motor (the red connector with white and pink wires). Now, you can see what's what.
Position the aircraft with the tail pointing toward you with all trim tabs centered (in the middle).
right stick:
left/right: You should see the swashplate move right for right and left for left. If they're moving the opposite direction, move dip switch 2 on your transmitter to the other position. Now, with the stick and trim tab centered, you should see the swashplate centered on the left/right axis. If it is not centered, remove the screw from the servo arm and reposition it on the servo to where the swashplate is centered and replace the screw.
up/down: When you move the stick forward, the swashplate should move forward and vice versa for the rear. If it is reversed, you flip dip switch 1. You're going backward, so you'll probably find that the swashplate is tipped back. You should correct this at the servo per previous axis.
It sounds like you've gotten your rudder under control, so we'll skip that side.
Once you know everything is basically centered, you can mess with the trim tabs. If it's still tipping back, adjust the up/down trim tab forward (up) until it is corrected. Whatever way you have to hold the control to correct the problem is the direction you should adjust the trim tab for any individual axis. If you're drifting left, you adjust the trim tab right. All of this should change once you center your swashplate. When you adjust trim tabs, you're actually counteracting a problem with the helicopter's balance. Once you get this fixed, you'll find that you are the owner of an entirely stable and controllable machine. Now you know why training gear is such a good thing. Every time I have everything apart, I use my training gear to make sure everything is still within acceptable parameters to avoid a silly preventable accident.
Good luck. I hit the ground at yesterday at 20 MPH and stripped my main gear and broke my skids. I'm out of business until parts arrive. The crash was my fault, not the helicopter's. I was flying in the street at night and a car drove by ruining my night vision. I hit the ground without haven seeing it happen. It was bad enough that I considered buying a Shogun and moving the electronics. I decided just to upgrade parts instead. A buddy of mine who flies Nitros inverted nose-in thinks I'm a genious for buying the Walkera. He hasn't heard anything bad about them, but he doesn't hang out with people who are naive enough to think "ready to fly" is literal. Right now, you're banging up something you have a minimal investment in. You could be banging up a $700 Shogun package.
