I've done a parachute recovered rocket version using a stuffer tube, basswood wings/tail and vacu-formed body and pulsejet, I did mount the motor in the rear of the fuse instead of trying to deal with offset thrust. The pulsejet was flow-through(hollow) and caused just a bit of offset drag that caused it to arc torward the pulsejet slightly....I did have the forward pulsejet mount and tail pass through the pulsejet pod and act as additional fin/stabilizer area. CG was well ahead of the front of the wing and the nose was heavy, I used two chutes and kept the nose and tail portions separate on recovery to reduce risk of slamming into each other.
I've also done a profile RC version made of depron that flies quite well on E-6 RC 24mm reloads, again I used a tail mounted motor, it's 39" long or so and weighs about 11 oz rtf...the profile and wingspan are close to scale, the wing location was moved back slightly to reduce the nose weight needed for proper CG. It's very simple to build and in the air looks the part.
There is no need on the profile model to shift balast the CG shift on mine is about 3/4" from slightly tail heavy boost to nose heavy glide but nothing I can't trim out with the full flying tail. Here's the rc version...
