RE: Enya 19
I recently put an Enya .19 in a completely destroyed Ringmaster I salvaged out of the garbage can and rebuilt, because the already drilled mount holes happened to fit it perfectly.
I didn't have much expectations for it flying that sized plane beyond round'n round slow trainer, but turning an 8x6 it flew the Ringmaster with truly surprising authority on a set of 55' .012's.
