I'm experimenting with putting two small tractor electric motors in the tips of the ramjet pods and using the rear mounted E-6 or E-12 RC load for boost, then transition to electric powered cruise.
I've got the model built, profile in depron, waiting for the receiver and second motor before I do some thrust testing. The rtf rocket will be around 13 ounces RTF and 2 ounces more with the twin motors attached. I can pop the motors off and fly it as a bg if I want.
It was a bit hard to get the white wrap/stripe to conform to the cruciform shape and still look straight from many angles, but I made the best compromise I could. Again, the top view nose looks short because it is above the centerline so needs to be a bit shorter than the side view profile.
You can see the motor mounts on the ramjet pods before painting, I just taped some spinners in place for effect if I fly it without motors.
