Hi,

today i was burn my 1st galon! what a bird!
im so happy and i want to share with you guys!
i have two questions .
1: Vario says is no good idea to use the heading hold mode in gyro.
on my bird i use this action and the tail is slight a little to left.(no sub trims or mechanichal etc) i was trying to give more sensitive with not results.its normal?perhaps no. i dont try yet to use it with normal mode. what is your suggest?
2: i used the 68/4 for swash plate at +4 and swash is 0 degrees the the travel of all linkage are perfect in min - middle and high pitch.
when i was in hover the heli is come back and need a few clicks to front for level hover.what is going on? i dont think is normal this.
(the swash isnt slide back in all of travel when i see on the ground)

thanks

Check the CG of the helicopter. More than likely the heli is a little tail heavy which is why it would drift backwards to you in the hover.

Same thing happens to me in my Vario Acrobatic's tail. It's drifting to the left in HH mode. It also happens to a friend of mine with exactly same configuration as mine. No clues?

First question - can you stop the drifting (I'm assuming you are in heading hold mode?) by adding some opposite trim? If you can and you are using a 401 then this can be due to temperature drift especially if you transport your heli in an airconditioned car and fly in high ambient temps like I do. Anyway, this is a normal occurance with the GY401 and it is mentioned in the gyro's instructions. What I normally do is add one unit of trim to stop it creeping and when I shut down after the first flight, remove the trim and it doesn't seem to require it for subsequent flights.

I have also heard that excessive vibration can cause 401's to drift but I have never noticed this effect.

Hope this helps,

Paul.

i try with trim option and it works. after reboot its the same problem (reset the trim). i have no difference in temp and i was carefull with it specialy on winter when i trasfer the model in hot car and outside is 15-20 degrees different.
on my raptor with the same type of gyro (GY401) i would never have problems

In my case driftin was due to engine tuning or too much vibrations. Now that engine runs smoother the tail is holding better.
