Kyosho used to make a 40 size PT-19. I have one and it's a very smooth and easy flier. It would make a great first tail dragger. I'm sure there are several laying around if you search a little.

In fact, if you are anywhere near central Texas, I'll sell you mine. It has a grand total of 3 flights on it and is setup for an OS .48 surpass. I built it to get my thumbs back in practice after being out of the hobby for 7 years. Everything came back quicker than I thought
