servo arms
Dear Danny I am building a Giant Areomaster biplane. It has a 73.5 inch wing span, weighs 20 pounds, and I am using (7) 2721 metal gear servos. Each aileron and elevator halve have there own servo. My question is should I use jrpa215 heavy duty servo arms (nylon) or should I use the ds168 Aluminum servo arms? The power plant is a 41cc us engine. I might go to a larger size motor like a 50cc or 62cc later on.
cheers al

RE: servo arms
The DS168 arms will not fit on standard servos. JRPA215 should work fine. Other options would be the new aluminum arms from JR,
JRPA236 SING ALUM ADJ SERVO ARM1-1/2"
JRPA237 DBL ALUM ADJ SPLINE SERVOARM 3"
or aluminum arms from Hangar 9.

or aluminum arms from Hangar 9.
