The LOC Goblin model rocket is a 4” diameter rocket kit. With permission to upscale a classic rocket, the LOC Goblin is here and full of new features. The most notable is a Loc-n-Mount system allowing 54, 38, and 29mm motors. At 42 ounces it’s light enough to be a Class 1 flyer, and with the main 54mm it can easily attain high power flights. Decals are included as well as all necessary hardware and rail guides. Recovery is with a 36” Rip-stop nylon parachute and 15’ flat braided nylon shock cord with loops sewn in the ends. The booster section can be completely assembled and then slid into the airframe for maximum strength.  OR still use the traditional fin tabs and slots. 

LOC Custom Series kits are designed to get away from the standard FTC (fin, tube, cone) rocket and may include a wide variety of building options. Using advanced techniques and bringing traditional modeling together, these kits will only go as far as your construction skills!

David ★★★★★

I was nervous about my first 4" build but the Loc-n-Mount made swapping motors at the field way less fiddly than I expected. The airframe feels thick and sturdy, and it went together over a couple evenings without any surprises.

Ava Y. ★★★★★

The Loc-n-Mount system made motor installation way easier than the old friction-fit setups I've dealt with. Finished mine in a weekend and it flew straight as an arrow on the first launch.

Sebastian ★★★★★

The Loc-n-Mount system made motor installation way easier than the old cardboard-and-glue setups I've dealt with. This 4" airframe gives plenty of room for a bigger motor, and the whole build went together in a weekend. First flight was straight and stable, no wobble at all.
