Reducing an insignificant amount of mass, that's the joy of tinkering. Getting in there and changing it out is more bother than it's worth. Whether minor weight savings versus practiced thumbs will rue the day, I suggest the thumbs will. For sure I would much rather experience a bent metal pushrod, than a broken skinny CF pushrod.

This is a known problem on the Artemis and like aircraft;
Hard landings where the tail strikes the ground repeatedly bends the pushrod
down where the link is soldered. The cure is a piece of hard foam or
balsa "under" (but not touching) the pushrod to support it during hard
landings...
So what were these pushrods made of???
When getting a plane ready for flying that comes with a metal pushrod I always replace it with the largest diameter CF rod that will fit in the tubing. I can't imagine doing otherwise. Is there any advantage in using a stock metal (heavy--bendable) pushrod?

Hey Tim,
Remember my first few months with my Artemus?
Landed more than once inverted because of NO UP ELEVATOR!
I kept bending the elevator pushrod at the bell crank in the tail on hard launches. In order to do that, the forces on the elevator servo must be extreme. I never lost the electrical connection, but it seems it could have been possible to fuse it somewhere, especially in the receiver where the printed runs can be thin.
