i don't want to use the stock springs but i can't find any 11mm springs to use. jp hobby only has 10 and 12mm.
got a flight report from a guy in the states flying with a gp-123. said it was a stress free maiden and it flew well. he said he cut the stock springs but it's still too stiff.
he said he developed a crack in the gear mounts. used stock cg and 35mm throws for the elevator and 30mm for the ailerons. he was happy with them.
