Aerobatic FAI F3C Contest > What is the best F3C head???

Thanks for all answer, what would I do without RR and all people here!

I think I will go with the Tempest FAI head (most because it would look really stupid to have a Hirobo or a JR head on a MA heli), Scott Gray 720 blade and K&S Paddles.

Is there any general recommendations on how to set up the head?

Should I have any negative delta, flybar ratio, what dampers (the softest I assume) etc?

Hi nicco,

I think that you are making a good decision. With metal blade grips I would stick with leading pitch arms and maybe 5 mm of correcting delta and keep the dampers a little on the medium to stiff side. The winder it gets the stiffer the dampers will need to be. Adjust the fly bar authority so that the machine does not want to go into the wind in a hover or try to nose up and back up away from the wind. More fly bar authority will cause the model to want to nose down and go into the wind.

Of course that are about a million other things that go into properly setting up a machine for contest work. Why didn't I get into 3D flying 20 years ago and stick with it. My life would have been so much simpler.

Because you'd break more machines than Carter had liver pills (you gotta do that to be competitive these days), and you'd be just another damned 3D pilot.

Hi Shawn,

I used to do quite a bit of 3D, but I flew very smooth graceful type 3D that was very flowing. I still do 3D stuff with my Stay See bodied Calibers at the field occasionally. Sometimes when I get bored with F3C practice I will catch myself doing really big multiple backwards loops and cuban eights which I try to make look perfect, just like I would if I was doing them in a contest. I have even tumbled my machines down the length of the field at a hight of about 30 feet, which is very cool with a full bodied machine which is worth probably five grand. And usually at some point I catch myself and think, you idiot. I actually have two Caliber 5s, a Caliber 3 and and Caliber 30. Unfortunately I never fly them because I hate the way small helicopters fly.

I personally don't think that I could ever punish a machine the way that today's 3D pilots do. I'm not saying that there is anything wrong with the hard jerky motions that you see today in most of the 3D flying. I just can't bring myself to abuse equipment like that. I won't even do that to one of my little plastic Calibers.

Has the wash-arms anything to do with the behavure of the head?

I have all plastic now, but I have full metal from another brand.

Hi Nicco,

The wash out arms have no influence on the rotor head other than the amount of cyclic pitch that they apply to the fly bar paddles relative to the amount of deflection in the swash plate for a given amount of cyclic input. If you have wash out arm with multiple holes so that you can vary the amount of paddle travel you can change the way the model feel and flies by quite a bit.

Thanks,

What about paddles?

I have K&S F3C paddles, some people talks about Rotor Tech F3C paddles, ther is some new, light ones from Century. Wish should I choose?

Hi Nicco,

The Fun Tech F3C paddles are the best paddles that I have tested. I have not flown the new K&S paddles and I have not tried a production set of the Rotor Techs. The sample of the Rotor Techs flew very well, but they have a lot of cyclic authority and required quite a bit of fly bar weight. This has probably changed some with the production paddles.
