If you go for the 4-star, check out this wonderful website:

I am going to build my second plane soon too and decided on the 4 Star after seeing his modified one on the web. I think his 4 Star is WAY nicer looking than the Rapture. I'm just confused as to whether I should build a 40 or a 60. From what I can tell, I can get a nice big 4 stroke for the 60 which will be usful in years to come too. I read that 60's handle much better too.

Hope that helps,
