The original TF P-39 & the TF gold edition P-39 are two different animals. It's like comparing apples to oranges. The red box builds old school with lots of balsa blocks to be shaped and no information on the plans for installing retracts or flaps. It's also smaller than the gold edtion. If you have built a few planes it's not a hard build though, and it flies good. I've built 2 of them in the past. I bought the gold edtion when it first came out. It's still in the box. I've looked at the plans & instruction manual. Judging from that, I would say the gold edition will be much easier to build.
