2 Apache Chipmunks are flown on a regular basis from our field (i'm planning to get 1!) From chats with the owners, the kits are good, accurate and very strong when built. They both seem to fly well on OS 120fs's being able to do all the scale manouvers. (I will however be putting an MVVS 2.10 petrol in mine!)
Hopefully the PT19 would be along the same lines, I don't know wether the plane is exact scale though, as the chipmunk isn't.
