I need to order a large double Aluminium servo arm about 3 to 3.1/2 inches long.
l have 2 spare servos l can use;
DymondDS9500
Ripmax Quartz QZ507.
A-short Aluminium servo arm on the Dymond appears to be a perfect fit on the Ripmax. So by coincidence appear to have same number of splines. I know it is not Hitec since l have some of those arms and too small.
Can anyone tell me how many splines for above, so l can order the correct long arm.
thanks
