Default Trex 500 ESP Flybarrless with 3GX Problems

Hi Guys.

I am picking up a very strange problem with my flybarrless heli. I installed a new 3GX unit on the heli and did the setup to the book. Test flew the heli two or three times and she flew like a dream. The next day when i flew her she hovered fine but the moment i put her in flight mode, the left pitch servo pulls down and the heli goes to one side, with some skill i could save her with correcting in the opposite direction. i Then checked dservo operation which was fine and tested correction directions which was also fine. i then took off in normal mode as usuall and then again as i put it in flight mode it did it again, landing again with some bobbing and weaving from side to side i decided to re initialise the whole system. did it and again the same problem. Even when taking off in flight mode. After doing this about 3 times it just stopped, then one can change from normal to flight mode and back again, no problems, stable as a rock. Now every time when a new battery is installed, it does it 2 or 3 times and then she's fine. I also went onto the net, got the newer version 2 Software and firmware and updated the units firmware also. Re did the setup. Checked directions and corrections and still the same thing. Only does it once or twice that you save it just just from disaster then you can fly with no problems. This really is a strange problem and have never seen this.

also i just want to add, i have cleared my model on the remote, setup a whole other model on the remote and re binded the heli and still the same thing. Checked also that no mixing is enabled.

Ditch the 3GX! It is a POS!
Get a good flybarless system!

Do you have any trims based on flight condition (normal vs idle up)?
