I bought a ARF at a local swap meet this morning. The seller didn't know much about it. I think it is a World models Tai Ji 40. It is complete except for the fuel tank, manual, stickers, tail wheel and aileron control rods. I gave 75 bucks for it.

I have a OS 46 FX With a mac mufler I plan to put up front. The motor mount is set up for inverted, but I want to change to side mounted. Also I have JR sport ST47BB servos that are new.

So my questions are, will this engine be ok, where can I use these servos, what are the minimum servos elsewhere, what tank do I need, What did this ARF retail for?

Any other insights would be appreciated. Also I'm not looking for killer performance, decent is just fine right now.
