Like you Chris I finally got my hands on a 310.
I had also been waiting for years looking for the right one to come along. Mine is built but was never flown by the previous owner. I considered doing twin DLE 20s but I don’t want to do all the required re enforcing to the wing.
I am strongly considering some RCGF 10cc gassers.
Roughly equivalent to a 61 2 stroke glow.
What is the purpose of filling the wing with foam?
Is the wing known to be weak?
Look forward to learning more..
