I have the Walkera V120DO2S with Devo 7 TX and 2364 RX.The 3 swash-plate servo's appear to be turning the wrong way.As they go down, the swash plate goes up which gives the helicopter lift.If the servos go up the swash-plate goes down for inverted flight.I have just replaced the main shaft, swash-plate and had to remove the TX speed control tray to get access to the main gear.I really can't see how I disturbed the setting to cause this problem.I don't believe any amount of adjustment of the ball links will rectify this.I did notice a setting on the TX that said REV. I tried this but no change.

While searching the net I have seen a number of negative,and positive, statements regarding the Devo 7 and that the Devo 8 is a lot better.Also the fact tha[8D]t Walkera will not bind with any other make of receiver.

Do you mean the pitch decrease when the swashplate goes up? If this is the case switch the blade grip to the other side will correct it.
