im building a raptor 90 / trex ,,,,its basically a raptor 90 with a full trex 700 head assembly on it...my question is the flybar travel is about 300% more then the stock raptor head and it almost touches the damn tailboom,,,would the flybar see this kind of travel in flight...I built this out of all new spare parts I had...thanks for any advice

Can you limit the ATV travel on the servos ALI/ELE and keep cyclic at 7.5 pitch degrees?

Had nothing to do with what he is asking. He is saying either powered on or off the flybar will move up and down (flopping around on the bench) and the paddle almost touches the boom when it spins around.

You will be ok and it will not hit the boom while flying unless you completely stall the blades and even than it would be hard for it to get to that angle. I would not worry about it.

R90 flybar
PV0395 flybar
SPECIFICATIONS
Length: 20.5" (520.7mm)
Diameter: 0.16" (4mm)

Trex 700 flybar
Flybar rod x 2(Φ4x570mm)

These are the size of the flybar length.

Like I said earlier, check the pitch travel of the cyclics.

If you want to experiment:

Shorten the Trex700 flybar and re-thread. Don't know how it will affect the response. I have converted a few 600n flybar head onto my Raptor 50. I do have a 700 head as well. With parts getting fewer as times progress. We are going to have to figure out a few things. I will follow this to see what you plan to do.

Generally speaking a longer flybar will give you quicker cyclic. However, if the flybar gets too long it will flutter at higher cyclic input and rpms. Do not do anything different with you cyclic rates as you have been before. Keep the flybar level and measure from the blades (you probably know this). Also, with a flybar we used a little more cyclic degrees verse setting up a flybarless machine (8-9 degrees will be plenty). Also, the cyclic has alot to do with weight paddle size. What kind of flying do you do?

So in flight the fly bar would never see that extreme angle as seen on the bench

No where near..... the flybar deflects a very small amount compared to the free travel you're asking about....

Been there, done that and old enough to know better.....
