Walkera 4#3B and the 2801Pro - Micro Heli Dreamteam

With the 2801Pro (2801 and 2801e should be similar) it is possible to setup the throttle curve, dual rate and expo for the 2406/A/B RX range. This is done by switching stickmode (COMPTB) to 2801, doing the setup, and then switching back to 2401 stickmode. The settings made will stay.

After going back into 2401 stickmode the bind should automaticly come back (if you left the rx connected to the battery). if not, just do a re-bind.

This video show how:

I just opened the 2801Pro from my 4G6 (great little helicopter) because i didn’t like the trottle stick tension. Tension was too strong and i dont like the snapping.

To get rid of the snapping i carefully sanded down the little plasic teeth inside the throttle stick mechanics. A very small amount of grease on the plasic and the metal locking-part makes the throttle stick movement even smoother.

I wanted to be able to adjust the tension screw without opening the Tx casing, so i drilled a 4mm hole into the back of the Tx.

Another thing to do would be to replace the bushings with bearings like Spektrum on the DX7. Heres a great how-to for the bearing mod on the Spektrum DX7 – should work pretty much the same way on the 2801.
