Yes, Royal did build a Phantom, I bought it in 1988. I will send pics as soon as I can. The motor mount was solid hardwood,(maple). It was about 5 inches long. I had to attach it trhough the fire wall and into the fuel tank area. I think the person that drew this up was on LSD at the time. But it looks great. and flys great! After I nose dived it into the ground I just put a Hayes Mt. in it. I also had to use a --Split -Elevator in it due to the fact that both elevators are slanted downward.
