If you are very carefull, and I used a hair dryer to heat the tube, a BT70 body tube will fit through it. I cut the nose off, and glued a bt70 coupler, then through the body on the fins to a 24mm mount. Works great on E-F engines!

I didn't have to heat the tube, the BT-70 was a perfect fit in my crayon...I cut the nose off where the yellow arrow is pointing.

I used clear fins (Lexan from Tower Hobbies), TTW

It's a great flyer!! It has flown on D12 and E9 motors.

You can find them at a dollar store . I have a 4 " crayon that comes apart and the tube is cardboard. Doing a 38mm on that one

I have a virtual build pile it saves space

I got mine from a Rhode Island based store called Ocean State Job Lot. It's kinda like a Wal-Mart.

Dollar Store, that was what I was waiting to hear. Will get there soon!

I picked up some nice crayons at dollar store. 1.75 dia. X 24" approximate.
R-Us is a good source for the larger ones, extra specialy after Christmas.

I sense a distubance at my work bench.......

And I smell a crayon drag race this spring.

Sorry that I'm arriving so late in this thread...

Bay Area Rocketry makes a kit that simplifies the building process. The kit is not listed on the website but through the site's "Contact Us" function you can request information on the kit.

The centering rings and fins are laser-cut and with the motor tube these parts form the fin-can internal structure and motor mount. Cut a few slots in the base of the crayon body tube and you epoxy the mount in place. Also included are templates for the slots and launch lug standoffs. Forgot to mention that a complete nose cone parts kit (3 bulkheads, t-nut, nuts, bolts, eyebolt) makes the plastic nose cone functional for rocketry. The included recovery system consists of a length of 1/4" braided kevlar and some stretchy nylon braid. My first kit came with a chute but the second kit did not.

You can order the kit complete or you can order just the internals which should save on the shipping. I launch my BAR kits (29mm and 38mm) on rail buttons rather than the 1/4" launch lugs which are probably a bit undersized from a rod whip perspective. There's always room for improvements and upgrades on any kit and I'm working on a dual deploy nose cone av-bay for use with the Cable Cutter to pop my main chute.

Anyone interested in a cheap L1 cert rocket? $65 for the kit, and $30 for an Aerotech HP SU motor will give you the tools needed to get your ticket punched. I've seen people building these on the range and certing that same day.

BTW, don't seal the slot in the nose cone. It makes for a great whistle after the motor burns out.
