Status: offline 		Yes hartar, that is what the reverse biased diode is supposed to do, maybe it died, but I doubt it. Is the problem with all the servos or is one of them twitching and not the others? I had a problem with one of my servos twitching like that. I took it apart and cleaned the potentiometer good inside and it is a lot better now, but still not as good as the other servos. They are really cheap servos. I actually drilled a small hole in the side of the bad servo right next to where the pot. is so that I can spray contact cleaner inside when it starts acting up. If you do this, make sure you use a plastic safe contact cleaner or you will be very unhappy.

Status: offline 		thanks for the info.. I would have never thought it was the servo but it was.. it had a bad connection and the vibration was causing the fluctuation.. I was able to fix it.. thanks for your help...

Status: offline 		Well I did some more experimenting with my tail motor problem, and I found the problem to be in the rx, I kept trying to fly it after putting the stock tail motor back on, and when I lifted off, It spun out of control, and crashed. So I deiced I would build a stand to put the heli on that would allow free rotation, Well it worked, and I fired up the heli with my old rx (remember my new one had a bad channel 1 for the servo) It was erratic as usual, So I decided sense I couldn't fly my heli with the new rx, I would try it on the stand and see how the tail motor works, Well It stayed steady for a bit, than it spun all the way around and stopped again, than started being erratic with tail wag, It corrected the peaky problem with the old rx, but I found it odd that it was so spastic, so I disconnected the main motor and fired up the tail at 50%, and gave a little tap on the rx, guess what Same problem as my old rx, If you slightly tap the rx it caused the tail to go crazy, The vibrations from the main rotor head Even though small was enough to cause the new rx to go erratic. I am tired of the cheap electronics from walkera! I am going to search out another option. This is crazy.

Status: offline 		i had exactly the same problem i posted a picture back alittle while ago of the part that gives the tail the eratic behahavior, i would tap the rx it would make the tail go spastic, any way tried fixing with a soldering irion but the iron was to big for the job and stuffed the original rx, ordered another one and nock my sox off it did the same thing. any way brought a good iron took the part off resoldered the little wires that connect to the bar resoldered the lot back on and no problems works like a dream . if you are going to do this on yours be very carefull when you take it off the board the four spots where it is soldered go underneath and if you do not heat the solder enough it will break the tabs off> have fun

Status: offline 		I tried that earlier, and as I posted it fixed the tapping problem, but now the tail is too touchy, it seems that part must slow down the current flow to the tail motor, and allow a smooth increase in the rpm, when I repaired mine, one of the tabs probably didn't get seated correctly, and is causing it to send the voltage too quick to the tail motor, resulting in touchy controls.
