I have noticed a wobble that is not related to something being out of ballance.

When I transistion from forward flight to hover, I get a wobble that dissapates over a little time (10 - 30 seconds). Is this something that can be attributed to dampening in the head?

I am running an AL 600 combo, with the align ESC and motor, using the grey dampers, SAB 600mm mains, Align tail.

I took a quick trip to the flying field this AM for flight #5 and was able to get some decent flying in (no thrashing or 3d). I flew a couple of hard climb outs, and circuits to approaches. This is where I noticed the wobble.

probably the head speed. what's your throttle curve, battery, blades, pinion, and pitch?

erniefritz · 11-28-2006, 02:14 PM

check your headspeed... wobble is usually because the HS is too low

if you are running stock gearing you should be at 90% or above on the throttle in hover , most run a straight 100% in idleup , also make sure your ESC is getting 100% throttle at full stick either by reprogramming and/or expanding your endpoints on your throttle endpoint adjustment...

Yep I am with Kong here.... Head speed is probably low in relation to amount of pitch in the hover.

The grey dampeners are the soft ones, aren`t they?

It`s possible to get wobble, if your Head is to soft for the high headspeed.
I would suggest both: increase and decrease your headspeed and see what happens, then insert the black dampeners and try the same.

Just took it out for flight #6. I really like this bird

Adjusting the Throttle curve fixed the problem.

Former T-Curve 0-40-80-90-100
New T-Curve 0-45-90-95-100
Idle up 1 100-95-90-95-100
Idle up 2 100-97.5-05-97.5-100

Pitch -9 to +9
Normal P-Curve 40-45-50-75-100
Idle ups 0-25-50-75-100

Thanks for the advice.

rookie question perhaps but, what is the purpose of the "05" throttle setting in idle up 2?

thanks,
dave

I would guess its a typo and should read '95', this is the usual mid-stick setting for throttle in idle up 2.

ok, good, I figured I was a challenging throttle curve at first...

Man I LOVE HeliFreak!
Just toook my new 600 to the field to try it out & wobbled like heck! Brought it home & went through EVERYTHING to no avil. Get on the Freak & WaLa!

Bumped my curvs up to what staplegun did & that got the biggest majority of it out. I think I'm going to chunck the stock gear & go for an 11 tooth!!
