I've searched but cannot find a relevant thread for my question(s). To anyone who has assembled and flown Great Planes' 1/3 scale Pitts Special:
What mods or reinforcement do you feel are required? Engine box area? Landing gear? Will power it with a Fuji 50cc, Zenoah G-62 or similar. A simple laundry list of recommendations or link to a thread would be much appreciated.

Reinforce that firewall!! Mine is powered with the Fuji 50EI, and the firewall is pinned, blocked and glassed. I bought mine used (here on marketplace) but I've been through it with a fine toothed comb. All ARF's need the gear reinforced in whatever fashion you choose. It's a fairly heavy model, and if your strip isn't perfect, can get abused on landing. I gotta say, I love mine, and it has proven to be one of my favorite flyers. The only downside? It takes forever to set-up and tear down! But the in between is great.

BTW, mine has four aileron servos, and has jacks in the top of the fuse to plug the top wing into. Slick set-up. (Thanks Speedy!)

Thanks reincarnate. Are you happy with the Fuji 50?

Yup. Had trouble getting it to start when cold (hand flip start). I added a velocity stack and an electric starter. Now when I fuel, I just put a squirt of gas in the carb through the stack, choke and turn through a couple of times, turn on ignition and she fires right away. After the first start of the day, I don't even use the starter. The stack seems to have helped out the idle and transition too. Plenty of power for my style of acrobatic flying. Plus that I can fly for 15 minutes with a good 2 minute reserve on a 24 oz tank of gas with aggressive flying.

Here is some information I found when I was putting mine together. Good luck.
