I had one that I wound up selling before I built
due to other committments , but all the ones
I have seen fly did really well. Older technology
but seems to be a good basic design. I agree with
mounting a 4st inverted on that plane as it would look alot better. I have a Dynaflite Spit 40 size
that has alot of the same kit features as the P40
with a Saito 56 and it is a perfect match.
I have fixed gear but retracts would be a
good addition.
