The X-15 has more body lift due to the wider tube, but one thing you probably didn't realize, I was launching the the Bomarc on E-12 Aerotech motors which are a 34ns motor to keep the stress on the airframe and pods light, the X-15 is launching on F-24's which are a 47ns motor, the X-15 boosts to around 425' and the bomarc to closer to 300 at about 1/2 oz lighter liftoff weight.

I've flown the Bomarc on estes E-12's and it is very similar in altitude/glide time to the Aerotech E-12 at the same weight. In some videos my daugher/son zoom in as the rockets boost so it is hard to see how high they are really going. Here is an E-12 estes flight which doesn't zoom in and it looks higher but isn't really.

I've flown the Bomarc on older E-15 Aerotech motors, which were 40ns motors, here is one flight, it gets about 100' more altitude and about 10 seconds more glide time, similar to the X-15 on F-24's.

In fact I just built a new bomarc version that cut the weight by 2 oz(14.25 oz rtf) that can fly on the E-6 motors and it now gets nearly identical flight times as the X-15.
