RE: Best 40 size ARF pc9
I've had PC9's from 2 different Manufacturers - Seagull (3 of them) and V-mar (1 of them)
I think the V-mar is a bit closer to true scale but it didn'e fly as well as the Seagull ones did (or do).
The Seagull one is a great all round flyer. - I ran OS 46AX's in all of them.
