Ditto on the World Mach 1. I instruct and have one in my "hangar" with a OS 46 FX for a backup and for keeping sharp with cross control landings. Fastest building ARF I've ever "built", there only 4 things to glue, the wings, the little ply plate under the aileron servo, the stick behind the fuel tank and the ply tail skid.
There is already a hole in the side of the "cowl" for a remote needle to stick through, the other side of the cowl is notched for the muffler to clear, not covered with shelf paper and is only $69.95
