One of the ADVANCED SERIES of kits, which include factory pre-slotted airframe and through-the-wall fin construction, the Big Nuke is our large scale version of the perennial favorite Lil Nuke. This heavy duty cardboard model rocket kit comes standard with a 54mm motor mount tube but can fly well on large H, I and J motors as well using optional LOCK IN adapters! We upgraded the shock cord to 18' of 5/8" tubular nylon and added a CEC-3 chain connector to the SCMBA-25 shock cord mount for heavy duty flying. Parachute Recovery. Rail guides included!

All LOC/PRECISION "PK-XX" kits include heavy duty airframe and motor mount tubes, high-grade precision-cut plywood fins, centering rings, rip-stop nylon parachute or streamer, nylon elastic shock cord and mount, launch lug, polypropolene nose cones and instructions.

Versatile and convertible!

I love mine. Can fly on as little as an H242T on small fields. Great L1 & L2 bird. has been damaged twice but is an easy and economical repair. Occasional dual deploy with the top half of my LOC 1600. Like a giant Red Max, simple, stable crowd favorite.

Great selection

You better check the website twice cause there's always something you forget

After building the Lil” Nuke, my son asked for the Big Nuke for his 12th birthday. After seeing just how BIG it really was when it got here, he was a bit intimidated and thought he may have bitten off more than he could chew. I reassured him that all the techniques he’d used for his Lil” Nuke would work with the Big Nuke.
By the end, his confidence was greatly improved. He is comfortable using the belt sander and doing quality fillets without supervision. The precision fit and quality of the parts certainly helped reduce his frustration along the way. He’ll be soon fly it for his TMP cert.
As a parent, I’m very happy to see his excitement at each step and with the skills he developed along the way.


Another great kit from LOC!
I did my L3 with this on an Aerotech M1350 to mach 1. No glassing or fancy build techniques needed!
