HI,

just wonder if anyone have found a slope free servo ?

Most servos today have more or less slope ; a deadly one for the servos, specially when installed in a "stroker-setup". This tiny initial slope become larger , and soon the pot`s are gone .. unserviceable for F3A.

The only servo i have tried without slope was back in the 80 `s - sanwa contest ( HC & HP ). Mechanically excellent for 500+ flights, and the pot`s became worn in a "normal rate".

HMMM ..... I am a bit suprised that the manufactures still make this kind of servo ; mechanical pot`s and non beweled geartrain all through ... Beside some small improvement it`s the same tech for abouit 30+ years or so ,at least as far i can see ...

In F3A the servo play a major role and we rely on it .. it`s hard enough to struggle with your fingers ...
