how would flying be affected if you *accidently* cut your flybar?
if your flybar was a little shorter, would cyclic response be faster? would anything even change? because i thought just the amount of weight that was on it affected response.
just wondering.

I think you might want to re-think that one! I don't belive I have ever read of shortning the flybar rod. The shorter the less stable, the longer the more stable!and one more thing "DON'T BE AFRAID!"

i havent pu too much thought into it tho but i think it would make the cyclic controls twitchy and unstable...maybe.
let us know how it turns out.

well, the accident hasnt happened yet, hehe. i was just wondering if anyone has done it.
i'd like to take off 10 mm on each side, but i know if i were to tell my friends, they'd be like "no, no, and no"
i know it's my choice, but i dunno....
maybe when i get another heli.

Why not buy another flybar and chop it? If it works, great, if not, put the unmolested one back on. What's a flybar cost these days? Just a few bucks...A helicopter is 10,000 parts spinning rapidly around an oil leak.

yeah, but also, if you cut it, you lose the threads where the paddles go. you could cut the middle, and have the cut in the center (after you take some out though)...worth a try.

The flybar controls the blades......
A longer flybar will make the heli more responsive than a shorter one.
The further away from the center of rotation the faster the paddle is moved through the air. The thinner air lets the paddle change directions faster.

I tried this a few years back with my Sceadu. extended the flybar an inch. That heli would flip fast.
then I shortened the bar and inch from stock and it took what seemed forever to get over.

Taken from the "Curtis Youngblood" book.
1)Lengthen flybar-increases Control Sensitivity (response rate), and no change in "Total control".
2) Heavier paddle- decrease in Control Sensitivity, and decrease in Total control.

So a shorter flybar will have a decrease in response rate.


Why buy?? when you can borrow and no return

exactly....
I also slide CF rod over the wire and ensure that there is pressure fit to the paddles. the cf will also and to the responsiveness of the bird.

an unstable aircraft is a very very maneuverable one. thats why all new fighter designs are unstable aeroduynamically and require the control of a computer to sustain flight.

the first flying wing built in the 40's was inherently unstable as well. however, they still made several successful flights with it utilizing human control. this translates to helos because shortening the flybar will make it unstable and thus more maneuverable. there will be a limit though so be careful and take your time!
