October 16th, 2009 RobZULU 2 comments

Put the HM52#1 landing gear (HM52#1-Z20) under the 4G6. The holes in the HM52 skids fit the front mounting holes of the 4G6 frame. Tailstruts can also be mounted without modification. HM52 alloy skids have been shortened.

UPDATE: Weight incl. screws and spacers 3,9gm. 1,5gm more than original LG  (2,4gm).

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.

Carbon tail rotor blades for Walkera 4G6

October 10th, 2009 RobZULU 3 comments

I had some problems with the tail not holding on pitchpumps with the Walkera 4G6 Helicopter. I’ve tried adjusting the rudder extent pot on the RX but even at maximum the tail wouldn’t hold. I always had some 20° turn on pitchpumps. I also played around with the gyro sense but that didn’t help either.

UPDATE: I’ve found that the pitchslider on the tail had too much play and caused the bad tail reaction. See my other post and vid on repairing the pitchslider. Still the longer carbon tail blades give a bit more power and a slighly better performance over the plastic ones.

I figured the tail might simply be too weak. So i made some tailblades from 0.6mm flat carbon, the same shape as the original ones, only about 5mm longer. They are 0.27gm before sanding and 0.26gm after sanding the profile and clear/white color (original plastic 0.3gm). The tail holds very well now, much more power. Also the piro rate is much higher now, i could turn the rudder extent way down and also decreased the D/R setting for the rudder channel. Only drawback is the increased risk of the blades hitting the ground – but im planning a new, longer carbon tailfin.
