Anyone using plastic servo arms sucessfully in jets? I know the $10 aluminum ones are better, but are they necessary? The HD black servo arms included with the premium Hitec digitals are extremely robust. I'm not even remotely concerned about the strength of the actual arm or any flexing of the arm....my concern is the arm "slipping" on the output shaft....not sure how much force this would take? Anyone with actual input on this?
As a comparison, Nelson sells an aluminum arm that bolts to the stock plastic servo arm for the 3D guys and many have used them without issues....I did have one of these "slip" a tooth on a 36% 3D plane, but was doing knife edge loops and aggressive blenders...no fault of the servo wheel

I would think that a 36% 3D plane with 45* of throw on huge control surfaces would be far more stress than the jets with very little throw at higher speeds.....
Thanks
