3GX - Nodding...

[chadvandonkey]

I've a small setup issue with my 700n & 3GX. When in forward flight it tracks true and remains in the attitude you set but if you increase collective the nose rises slightly and then dips when collective is lowered. It's nothing major just a little irritating. Is it simply a case of needing some more Gain dialing into the elevator? It's set near max now.

As a side issue I have slight tail drift which I believe is due to vibration. Heli has no drift when initialised but it drifts once the engine is running even at idle. Is there any recommendation on mounting the 3GX other than using a single align mounting pad - maybe 2 sandwiched together?

Thanks in advance.

I got rid of all mine because of this situation!!!

Coolice...?! The lad needs rescuing! Coolice is the 3gx man on here and he really knows his stuff. Give it a while and i bet he reads this post... if not pm him

Which one - nodding or tail drift? The tail drift only occurs whilst the engine is running, it creeps round to full tail on it's own despite resetting the gyro side of it several times over. This is why I believe I need possibly 2 3GX pads sandwiched together to give it some vibration resistance.

I've not even mentioned the backwards drift haha!!! Seeing as I set the swash level in DIR by line of sight I'm holding off on this until I get a swash level tool and reset in DIR.

Seems the 3GX doesn't have too many fans but in direct comparison to my 700n when it was flybarred it flys 10 times better now.

chavanddonkey, which version of the firmware are you running, have you done the V2 update yet?

[chadvandonkey]

Yes mate it's running v2 firmware. Turned the gain up a little and it seems a little better. The tail drift is more of an issue really which i'm sure is vibration.
