Default RE: Dowel control rods?

Sorry, but a mistake made quite often with model RC planes it to apply larger scale scenarios, which tend to scare the RC enthusiast.

This is one of those things.

Wooden control rods have been in use for some time as they are quite effective and safe.

You are ( now ) refering to "G" forces experienced in a crash versus actual in flight behavior which was the original discussion.

While it is feasible that any extra weight, even a few grams, can through "G" loading, in an abrupt stop, help increase the risk of servo stripping... The amount of force this would require and produce will effectively obliterate any plane. The plane would disappear.

Most dowel pushrods weigh in at under .3 oz. A 30 G crash would produce 9oz of force at the servo. Even a standard servo has no problem with this. Indeed any servo that suffices to prevent blowback in a model would be safe.

Dowel pushrods tend to be used in mid-sized or larger flyers. Typically we use higher torque servos in these planes. Here the "G" forces exerted in a crash have a lesser effect due to the higher strength servos.

While you may have experienced servo stripping in the past, it is likely NOT due to the presence of a dowl pushrod.
