That "was" one of my favorites. I fly all sizes and used that sometimes as a warm up plane. About a year ago it went in due to radio failure. I had a ST G90in it with a 12/9 prop and it was a 100mph plane here at 5000ft. I would come in for a low pass at full speed 5 ft off the ground, let go of the sticks and that thing held like it was on rails.
Sohhhh, Santa brought me another one. Now I always over power my planes but i suggest a 61fx or similar size. I built the Candyman version for my buddy a few months ago. I put a 61fx in it and he loves it with a Pits style muffler underneath.
Now as far a assembly, its goes together really well. Here is what I do and i guess its up too you.

1. I always apply some fiberglass/epoxy to the firewall corners for added strength.

2. Don't forget their is right thrust already built into the firewall. You can see this by looking down on it from above.

3. There have been alot of people complaining as to how weak the landing gear struts are. Well its my opinion they do not know how to land very well. I flew mine for two years with no problems. Also slop some epoxy in and around the retract mounting blocks for added security. I feel this is a must. You'll have to take the retracts out but its a simple task.

4. Add a strip of fiberglass to the wing halves also but i only go up about 4 inches from where the wing bolts on. This way the air scoop hides it You'll see what I mean when you get it.

I also use Kavan wheels, they help the plane slide sideways without bad wheel hopping when the end of the runway comes up quick.

This time i have the Miss America version. I am stuffing a Saito 100 in this baby. I had to beef up the back end and run direct rods to each elevator. its going to be a mover.

I think you'll be very pleased with this.
