Oh, that does bring back memories!
I had the Mustang and a PT-17 trainer a P-40 and my brother had the Stuka (which crashed). They were lots of fun. To think we use to fly them in the school yard full of kids! I wonder how I didnt hit anyone in the head with it!
I only stopped playing with these when I got into model rockets later on. (another addicting kids hobby.)
