A P38 is a nice dream, and a warbird with two motors is so cool. But be careful with your bucks.
A buddy had an E Flite P38 which did fly great (at least until he got too cocky and crashed--not the plane's fault). It is definitely not a beginner plane. And as an "ARF" it is a complicated plane to set up with two motors, and didn't sell well and this is probably the reason E Flite discontinued it. I got the last one our LHS had now on the build table, and it takes a lot of tinkering. I figure a P38 is a challenge, and guys here are making book on mine
The Banana Hobby ad is suspicious. Click the link in the second post on this thread by Orion Pax. The pics look cool, but no videos. The ad is full of redundant hype with obvious Chinglish wording. Properly functioning retractable gear on a P38 of that size is hard to believe. And the "ready to fly in just minutes", "super stable for beginner" and "high roll rate" make experienced guys cringe.
Personally I would wait and see what actually happens with the Banana Hobby P38.
