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.

The new E-Flite Blade mSR is a fixed-pitch, palm-size RC helicopter. Looks like E-Flite’s answer to the Walkera’s 4#3B
