I don't think you would have much control without a flybar and certainly unstable ,but I could be wrong I'm not going to try it.

Hi Ian, not seen any referance to a flybar less FP micro. Think I know what your next project is then

See you Saturday at Swanley??

Hey Graham,

Hehehe, don't tempt me you know I'm up for a challenge and a laugh. Spot my Hummer under the bridge!

It's a shame but as we know an FP Hummer, Elite or V3 will never work as a fixed pitch heli as it is the flybar which gives us cyclic control and not the blades. There is just hiller input (I think) from the blades back into the flybar system as the rotor disk deflects with air disturbances.

The only way to do a flybarless Hummer would be to convert an Elite CP or 3D PRO, which has collective pitch and so cyclic inputs are feed into the blades also via the swashplate.
I've always said I'd have another go making a multi-blade micro model like I did with my 3 bladed Hornet, but I just don't have access to a machine shop anymore.

Some projects I'd like to try out one day are :

1. Reversing the V3's blades to allow it to fly upside down. You'd have to take off by hand but what the hell it would be fun.

2. A Chinook style V3 or better still a collective model.

3. Aligning 4 Hummers in a diamond shape, joined by carbon rods and flying around so it looks like their in formation. Control & mixing would be a bit like that 4 rotor model we saw a few years ago, with 4 small props arranged in the points of a compass.

Fun to dream up, even better if I ever try it.

Swanley, hoping to mate. Fate has given me a dose of the flu again and so I am playing it by ear But don't want to miss out on all the fun

See you soon mate.

Forgive my ignorance but wouldn't a flybarless set-up simply be a Bell head? Tom

Hey,

This is an area I am not entirely sure of myself. Reading an article in one of the latest magazines last night again, the little V3 I think has Bell rather than Hiller mixing.

Having said that a flybarless head I think wouldn't be either, as there is no flybar then there would be no Bell or Hiller inputs from it.
Again I am not sure and maybe totally wrong.

Hey,

Thanks, it was a good project. I've sold it now though, hopefully they will take it further as I couldn't devote anymore time to it since having other toys to fly for Century.

May see you there then.

Spot on there Ian as usual. But what about taking an Elite FP and connecting the swash directly to the main blade holders. No collective input, just cyclic I think.

Hey Graham,

Sounds like it could work to a degree, but thinking about it now before I replied I think you'd then get tracking issues with the main blades having pitch in them already.

Will have to ask Dean if there's any spare FP's lying around to play with

I can imagine the response now

A couple of vids of my FP Hummer V2 Flybarless (select original quality for best results)

Has anyone else got a FP flybarless Hummingbird...please?

doh just me then ...I guess I will ask you guys, well the ones that think it is possible for it to fly (rofl sorry couldnt help it) ...: It keeps sliding off the hover, would more tip weights help it or more rpm?

I think your way out on your own here. What little I have read about flybarless setups I would go for more tip weight for extra stability.

Just to show you that Pigs isn't totally crazy. (Well he might be, but that would be a different subject.) There are a couple of us who are playing with this.

Oooh, this is looking good.

I wonder if there is a slightly better layout than what you are already using. I'm wondering if instead of having the controls rods being held in place by the fuel tubing, why not cut the balls off the flybar carrier so you can mount them behind the balls, then use the tubing to hold the balls back in place with the links to the head plate again.

Good project though & nice to see.
