Vibration N5

[AlanzoNembhard]

just order main shaft bearing an ill let you guys know by this weekend if i have a chance to fly

[Tommy Wagner]

Alanzo is so nervous that he is shaking the heli from himself shaking the sticks!!!!!!!  Just kidding I was with him this weekend trying to sort this out he replaced the bearings in the clutch stack and new clutch.  The wobble is not as bad while the heli is under load it wobbles more when you come down into a hover like the gain is to high but it's only at 45 ali and 50 on ele ( if I remember correctly) one thing that I was thinking the sensor is mounted right in front of the start shift don't know if moving it mite help this it's a YS 56 runs good maybe a little rich

[Jerry Kovar]

I run a Ys 56 on the rich side of things... I can induce a slight wobble if I richen it up any more... run it leaner and it smooths out some.. I just found a happy medium...


could be a governor issue?   try flying it with straight curves and see what happens...


does he have a metal plate sandwiched between his FBL sensor?   I have found that helps out as well on some setups...


also how was the bearings in the grips themselves?

Hey Alanzo
I have had a wobble from day dot, played with the gains for ages, changed all the shafts and upgraded to n5c bearing blocks and complete n5c tail, I am also using the CGY750, It was suggested to me H/S and a harmonic vibe, change the head speed so it dissaperes, I have NORMAL 1680, Idl up 1 2050, and Idl up 2 2150, this has made a hell of a differance, I will be able to have a good fly this week end so I will tell you my final H/S that works for me ,
it sort of made sense, wobble, gain, head speed,

cheers Bruce

@Biggles i will try those head speed tomorrow and what is your gain number at im glad i got out the vibration. Now i can really set my gain number and get those number lock in @kevin thanks for checking on me

[Biggles]

low 80's on ail and ele and I think the rud is at 70, I think, tail has been rock solid all the time.

[Biggles]

Alanzo,
today was the first chance to realy try those H/S's and my wobble has gorn, had the best flights ever, now I can get to enjoy the thing...

thanks to Justin from Extreme Heli's in Oz
