Hi David,
I happen to be putting one together, and I think you would be safe in using everything in the ARF .
Mine is an ARC, and I will be using electric, so I’m using the plywood radial mount for the motor. I think it will be a nice Model to bang around with. Quality is as good as any I’ve seen. Don’t know, in a competitive situation, how well it performs, but I think it is a fine ARF kit, and should fly the pattern well enough to learn from it.
There has been criticism, and some “heat” about this airplane, but don’t let that stop you. I’m not going to presume I know anything until I fly it. The airplane will be finished in Ultracote flying surfaces, and some sort of rattle can finish on the fuselage. I think it was Brad Walker who designed it, who, is also very knowledgeable about 4 stroke setups. Seems to have all the “numbers “ used in modern designs. Go for it!
