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.
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.
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.
RC Groups User marc31 just presented the first brushless conversion of the PicooZ. The mod is based on the 2.4 GHz Walkera 4#3B 4-1. The cyclics are controlled by actuators.
Most powerful setup I’ve ever had.
Max. thrust measured 146g with 450mAh zippy lipo.
RX2406B, removed original power cable
C06/ADH50L V2 21 T pinion w/ XP 7A ESC
HP03 2.9g w/ nanoheli flea tail, Q-tailblades
customized 4#3B V2 frame for 3mm boom and LG
central powersupply on mainframe w/ extra socket for additional plug-n-play electronics like onboard camera, led-system etc.
custom 3mm boom w/ jasonjetski tailcase, no fin
custom “lowrider” LG
custom CF “no-flex” blades w/ about Q lift (from CQE Flash)
custom CF lipo mount for 450 or 600mah zippy
59.2 AUW w/ 450 zippy
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.
Maiden flight of my PicooZ (PicoZ, Pico-Z, Havoc) with 2.4 Ghz Walkera RX2406. only 2 Channels Used. Super smooth flying, no cyclics, foward speed is only controlled by center of gravity. AUW 12.4 g. held together only by clear tape.
thanks to EQMOD on RCGroups who did this mod first.
for the cyclics, im planning to use the actuator / servo board mod, here is my test-bed video:
