Default RE: SLOPE FREE SERVOS ?

Hi Rune,

Cold this day`s to fly, but i found my winter-suit and the "statoil-coffee-cup", so actually it is ok , if the wind is not too strong ...

Servos;
I have tuned the dampers so they do not restrict the servo-speed, at least not on ground ... I did some different high-speed / high rate snaps without remarks, still the same feeling , so it seems ok. Several pistons/oil viscosity have been tested to achive the best dampening characteristic without restrict the servo-speed. There will be some friction, but not more than a "tightly hinged ailereon".

This is a type of Damper with large piston area to give a dampening effect with little travel, together with small holes with thin oil to assure good flow at lower speeds, but restrict at higher. The oil ( silicon-based) manage temperature variations very well, and the damper was still working after a longer time in the freezer ...

Well, time will show how everything works ... But i hope they keep my new servos allive longer than my previous ones ; They didn`t last more than 100 flights ...
