Hi everyone. Several years back my dad gave me a Nitro Trainer 60 Kit with no radio, electronics or engine. Back then I was way too young to understand how to put something like that together. Now I want to put this plane together.

My RC Experience:

I have owned several Hobby Grade RC planes, cars, and boats before. I have built things with servos and have experience with brushed and brushless Engines.
Some of my models include: Exceed Sunfire Brushless, Exceed Driftstar Brushless, Traxxas Rustler VLX, Piper Cub Brushed, Wild Hawk Brushed and Cessna 182 Brushless 4CH
I have a lot of experience with rc systems but never with nitro engines, but I think I am ready to bring on the challenge.
I am 16

INFO ON THE PLANE:

So one problem is I can not find a brand name anywhere on the plane or in the box or in the manual.
On the manual, all it says is Trainer 60 in bold letters.

Specs:
Length----- ----56in (1422 mm)
Wing Span-----70 in (1778mm)
Wing Area-----900 sq.in (58dm²)
Engine----------0.61 cu.in 2 Stroke
Radio-----------5 Servos / 4 Channel


It looks exactly like this: (colors and everything)
http://www.nitroplanes.com/nircaisptr461.html

but... the specs are a little bit shorter on that page than on my manual. For example, my plane wingspan is 70in but the one on the webpage says 65in
also, the one on the page says it needs a 2C 0.40-0.46cu.in; 4C 0.45-0.61cu.in engine but mine says 0.61 cu.in 2 Stroke


So my question for now is, What engine should I use in this plane!? This is all I have to go off of for now


I ATTACHED THE MANUAL COVER IT CAME WITH


THANKS EVERYONE!
