Status: offline 		When I hover the heli the pitch or collective is REALLY sensitive or touchy. What can I do to make it smoother and not soo touchy.. I have a futaba 8UHP radio in it..

Status: offline 		One of the easiest things to do is to "soften" your heli pitch and throttle curves around your hovering point. For purposes of this discussion, I'm going to assume you're hovering at mid-stick. You probably have your pitch at about +5 or +6 depending on the blades you're using. Your throttle is probably about 50% or a little more.

If you have a straight line "curve" of 0-25-50-75-100 on your pitch set-up, try taking the mid-points closer to the center. Like 0-40-50-60-100. You'll have to adjust your throttle accordingly, but this should help.

Also if your head speed is really high, you might consider slowing it down a bit for hovering maneuvers.

Status: offline 		As FordRollo pointed out, your pitch curves may be a little steep arround center stick.

One other thing you might try before reprogramming is using the pitch and throttle dials on your radio. Up your pitch a few clicks and/or reduce your throttle a few. This will reduce your headspeed and consequently collective AND cyclic sensitivity.

If this cures the problem, you could then adjust your curves to slow your head speed.

Status: offline 		Johnny9390. Now we can understand better what you were asking. Simply reduce the negative pitch settings on your 8UHP to get, say minus 2 or 3 deg. in normal mode. Keep your headspeed up at the low end so that when you descend, your heli doesn't get sloppy.

You'll find that you don't need much negative to get the heli down nicely. Experiment with it a bit.
Good luck.

Ford

Status: offline 		By the way, yes, heavier paddles DO increase STABILITY, but do not affect response in pitch. They affect cyclic. I personally don't fly 3D. I fly low, slow and smooth and when I do aerobatics, it's no more than loops, rolls, stall turns and autos. So I fly with heavy blades and heavy paddles...and my pitch curve is soft around the middle for smooth hovering. I don't have a
"twitchy" heli by any means, but it flies the way I like it.

Status: offline 		Johnny, we spoke before, you haven't told us about your pitch curves and throttle curves, or what mode you are flying in (normal, idle up, etc.). If you set it up as per minature's instructions, the pitch curve is very steep on the bottom and very flat on the top... if you just leave the top and bottom pitch alone, and make the curve a straight line (forget about the 'hover at half stick' thing) you'll be much happier with the results. Blades, head speed, needle settings, fuel all effect the way it hovers. We need more info to help.

Thanx,
Gary

Status: offline 		Here is how I set up my heli. I started out with Idle up 2, made everything 90 degrees to everything. Then on the pitch curve I tried to get as much neg to positive as I could and tried to make the numbers linear. then I went to normail mode and set the blades at -2 to +9. On the curve I have it at on the five point as 0-25-50-75-100 and throttle accordingly..

Status: offline 		I am gonna try 0-30-50-70-100 on the pitch curves to see what that does..
Does anyone here use mixing on the airleron elevator to counteract rolling or pitching on certain maneuvers?

Status: offline 		I add throttle in a mix for high delta pitch and roll manuevers, and it helps the old OS hold the headspeed. Saving for a GV-1 to deal with it tho.
Other than that I let my thumbs do the flying.
And I'd go further on the pitch curve.:
20 - 35 - 50 - 65 - 80 for hover mode.
I Crank it up in the idle up 1 then back the endpoints off again for Idle up 2 which is for 3D, this leaves a bit of power for cyclic vs collective in 3D.
Just my $0.02
