I'm putting one together now. Get a dremel tool you will find all sorts of uses for it, you will need to grind away some of the front of the plane for muffler clearance.
The fuel tank has some undersize tubing you will need to use wire to clamp on the fuel hose or get a normal tank.
I'm putting in a magnum 61 four stroke in mine. I thought i had an old enya 48 4Stroke but couldnt find it.
Ive been out of the loop for a number of years, There are some nice ARFs out there but I miss the ability to perform some tasks during the construction process. Adding a tank hatch or beefing up a fire wall ( or the landing gear block- hint - hint).
In any case its a nice kit, it should be in the air next weekend. good luck
