I just completed a bell hiller mod implementation on a Walkera 4#3.

So what exactly does this do for the heli? Why not just get the 4#3B and be done with mods all together???

4#3B is not using a bell hiller head.

Rotor heads will bell hiller mixing makes the helicopter fly much easier by reducing the delay from TX cyclic inputs to actual heli response.

A good idea to try and I'm glad to see that it worked out so well for you eqmod. I don't think I'll be doing this one on my 4#3 since it's quite mobile enough for my tastes already

Yeah but it's such a simple heli to begin with. Why mess with it? The new 4#3B has all metal head so it should be pretty snappy (I know, I've seen one fly in over 15mph winds!!!). I'd love to get one myself, but I'm already pushing my luck with my Knight and Atom being built simultaneously!

even with the metal head, you will still be dealing with the delay from swash cyclic to main blade.

I bet even with the stock metal head cannot do this;

Rapid Cyclics:

Some stable hovering:

Or hovering close to 1 inch above ground overcoming ground effect;
