Todays Flights:):(

[Graham Lawrie]

Well I managed to get out briefly A lot to do as the daughter goes to college tomorrow

Trex 550 as always on the Brain rock solid, 3 nice batteries through her, 1 bad battery I never flew, the one I crashed with, lost power on the ground as I did pre flight checks, lucky it was on the ground

Trex 450 started ok then the vibration came back mid hover, checked over , nothing found, tried again, same thing. If this had been on the 3GX it would never have been able to fly. The AR7200BX I was able to fly and land even with massive vibration

Back to the bench 600 off due to servo and tail issue, 450 off due to vibration......good reason to get a Goblin 380 me thinks

Lower your cyclic gain on the pots on top of hte gyro. Sounds like they are just a little too high.

 

[Graham Lawrie]

On the AR7200BX? Tony

 

[Tony]

Yeah. if the vibration that you are talking about is a cyclic overgain vibration, then just lowering that #1 pot should stop the vibration.

 

[Graham Lawrie]

I will try that she is stripped down at the tail/tail boom and main head at the moment. Spooled up and there is no vibration from the main gear now to rebuild and hunt it down

Get us some video Graham. Lets analyze this vibe.

Flying my 450 yesterday, battery change and violent vibrations hovering. Landed and seen I hadn't strapped the battery down tight enough...
