It looks like it -was- an Extra or maybe a Giles.

I wouldn't be afraid of an Aircore plane. You might like the idea of folding your plane into existence then gluing the joints. Just take your time with this and do it PRECISELY the way Aircore tells you. If you're not sure, go ask your LHS (Local Hobby Shop). I'd recommend purchasing the plane there if you can. They're fairly cheap all around, so an extra $5-15 to LHS will probably go a long way towards you completing the plane properly.

I have an OS .46LA on my trainer. Honestly I think the FX might be worth it in leiu of the LA. (OS - an engine company makes 2 varieties of engines in this displacement in what is called two-stroke design). The OS .46LA is certainly cheap and will have enough power, I think for your plane. The OS .46FX will have more power and will also run on 10% Cool Power (which is cheaper than the fuel I ended up having to buy for my LA). I also feel that they start easier, run better and last longer. For an additional $50 it's not an insubstantial investment but I feel it's worth it.

You've also got a radio to look at. Radio forum's that way ==>

Keep in mind corplast (that's the plastic material the Aircore's made of) is NOT indestructable nor does it tolerate heat worth a darn. Also, if you nose-over the plane into concrete you run about a 50% chance of kissing the engine bye-bye and some of your radio gear might get damaged as well - despite the rest of the plane being in good shape. Of course, a balsa trainer will likely disintegrate, or be at least severly damaged, in addition to the afforementioned engine destruction / radio mangling.
