T-rex 800 vibrations

[Koippa]

Hi.

I have T-rex 800E in aerial photography and videos. Now i think, what is best head speed to get most less vibrations? I get at 1700 too much vibrations, 1800 is better. What you think head speeds less than 1700? I have about 3kg more weight than normal 800. Photos are good mut in HD video there is vibrations.

Thanks.

Lower headspeed my friend say like 1600

Today i try 1550, quite good, some vibration in camera in every few seconds. Must try 1600rpm. Castle Ice 120hv don't want governor less than 1500.

I have a Trex700 stretched to 800 and it flys pretty well at 980 rpm headspeed. Rolls and loops are a bit slow but it sounds great.

What about the Main- and Autorotation Gear? Are they rotating smooth and on line?
My do not and i think the vibrations come from the Gears. I am not happy at this moment with the black Gears.

1800, dear lord. My 700 stretch with Cc 120 can do 1420 governed but flies best at 1500. This is with a 112t main and 12t pinion. That head speed you have for aerial seems too high.
