hello if i read it right a 60X14 wing if this wing is a candy bar type your c\g should be 3.5 for nose heavy which will cause snaps ,try 4.5" this should take care of the snap issue, plus you
should have at least 280 sq" horz stab with elv. need more info about plane to fully correct
problem. but as in post c\g at 3.5" is to nose heavy. anthony@customcraftedrc
