Mario took some shots and edited a video of me testflying the Walkera 4G6. Thanks Mario!

perfect sunday:

T-Rex 250, 4G6, 4#3B

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.

PicooZ Pluto (Havoc) actuators controlled by servoboards and the Walkera 2406 Rx (2.4GHz). Centering magnets used. Second vid down is a little flight demo.
