Trying some different props on the 2gm motor
GWS 2.5 x 1 20gm thrust
Parkzone Micro Cessna prop 19gm thrust
Parkzone Micro Citabria prop 28gm thrust
Parkzone Vapor prop 25gm thrust (too big)

The Micro Citabria prop looks to be the best that I have to try.This is the 4500kv version

So the Citabria must use something close to a 3020 prop which is what HobbyCity suggested to use with these and suggested 30 grams thrust.
