Great photos , they are going to help massively, as neither of us have ever built any kind of model before!!!! Thanks very much.
Well, this is not news you will like hearing, but a PBY seaplane is a pretty bad choice for beginners, assuming you have no flying experience. PBY models have a few slightly quirky flight characteristics. I have a good bit of experience on several different sizes of PBY R/C models, rading from 51" to 120" in span.
But, perhaps you have some flying experience with ready to fly models and this is the first ARF you have tried to build?
Do you have any flying experience at all?
