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:

lil’ demo in the livingroom with my modified Walkera 4#3B helicopter: backward circles, piros etc.
CQE Flash carbon blades, bell head mod (see my post here), ADH50L / XP 7A 20T pinion, 2.9g tail / flea, RX 2406B.

Before I start: This mod really does make a huge difference. It will make the 4#3B helicopter responsive like never before, self stabilizing and not rolling in any other direction than your stick input. See my videos here.

But only if the flybar angle is set exactly to 45°. If its not, you will end up with the same performance as in the known Bell/Hiller Mod or the other available b/h mods with the original 90° flybar. However with this mod the flybar angle can be set. I’m working on an improvement in how to set the angle exactly AND have it stay that way (thinking liquid metal, loctite, epoxy, bigger screw…) Maybe someone will come up with the perfect solution.

Bell Head on the Walkera 4#3B

Mod made from stock parts. The flybar angle can be set between exactly to any angle around 45° (+/- 10°). The result is pretty much what the Walkera CB100 will be like.

With this mod, the left-rolling problem of the well known 4#3B Bell/Hiller mod is eliminated because phasing can be set exactly. More about parts and how-to later.

UPDATE: scroll down for a 10 seconds hands free hover video.

You can actually see the shape of the B2 carbon blades from CQE Flash.

Thanks for the vid, Mario!

i just made some outdoor video with an onboard 5.9 Gramm Spycam board. Total weight of the 4#3B with video is about 62 gramms. Around 4-5 mins of flight time. it feels a bit heavy.

i used a 4GB 20$ Spycam that comes as a pen. removed the “pen” and used only the PCB/Board. Its fun. i need to get the camera angle more upwards – a little bit to much grass in the vids, but some people to.

where to get the cam, just google spycam pen, amazon, ebay, you can get them anywhere.

The camera needs to be cut, the pcb taken out, the camera lipo needs to be removed and powerd by the heli lipo. and the sensor-chip needs to be brought to an 90° angle.

Some outdoor flying with the walkera 4#3B sub-micro rc heli, rewound C05 main / flea, HP03T tail / flea, RX2406.
