AQM-37 Jayhawk mach 4 target drone


The Jayhawk is a neat target drone, and one of my favorite rocket kits when I was a kid. It's rated at mach 4. The wing is pretty small, a 3.5' wingspan for a 14' long rocket, since at Mach 4 you don't need much.

I found some spare 2.6" lightweight tubing and nose cone I had and decided to make a Jayhawk like RC rocket glider. The 2.6" tubing is very light and the tubing+cone comes in at 4.25oz total. I combined that with one of my Hypersonic wing sets from the kits I make and played around with a stability program to ensure that my flight CG and the lateral stability with the wingtips would work out ok.

the wing is larger than scale to support flight, and I had to chop the lower part of the wingtips down a bit so that they wouldn't drag on the ground. I built a conduit section from laminated depron, mounted my rail guides and skids on that which helped raise it up off the ground some more.

Will use elevon control, 24mm E-6 long burn rocket motors.

painted rtf with motor is 11.25 oz

20" wingspan, 36" long, 2.6" diameter.

Thanks! Did two flights today, flew perfect, did not touch boost or glide trim, really nice and easy.
