I bought this kit a few years back and finally built it to fly at BALLS 30 this year. I put in an internal tube and stiffened the whole airframe with foam and used a LOC Stiffy Tube Avionics bay. The rocket was built for 75mm motors and I flew it on an AT M1350 at Black Rock... It flew great, recovered great and still looks like new. LOC has sold great kits through the years and their products are well made and all fly great.
Right out of the box, this is an impressive kit. Everything needed to build and fly this impressive rocket is included when you open the box. I bought this to use as a bridge to building large rockets, and I eventually decided to use it for my Tripoli level 3 project. If built out of the box, it would prove to be a lightweight sport flyer, capable of handling anything from 54mm J motors up to 75mm Ls. I built mine strong, by reinforcing the airframe with fiberglass, and then strengthening the fins with fiberglass as well. I also added the LOC 5.5” avionics bay, turning this into a dual deploy rocket. Granted, I made a few modifications, but it is still a LOC kit at heart. I have built several kits from LOC over the years, and they have all been straight forward and easy builds, and the 5.5” Sandhawk is no exception!
