Default logo 550

Hi I'm dialing in a new logo 550 (metal head version). I built this exactly as per book, scorpion motor included and pinion included. When I flew it I had a little elevator jiggle jiggle up and down. Experience tells me the head speed is low, so I raise it and it gets better.

I tried it with and without the optional washer to increase or decrease damping doesn't really make a difference. ITs not till about 2100 that the little veritcal jiggle jiggle in the elevator completely goes away. 2100 doesn't seem that fast for a 550. But the included gearing is not very useful much past 2100.

Am I doing something wrong ?
