Brief:
I build Crayon rockets. Seriously. Ahoy! Begad! Blimey! I get t' big Crayon doubloon banks from Toys R Us, and turn them into high-power rockets. Begad! Blimey! I have a 38mm, 54mm tube-fin, 38mm 2-stage, and 38mm cluster version. I also have a 54mm 3FNC version that's under repair. Arrr! Blimey! So that's t' family. Blimey! I had someone who knew o' me crayon fleet give me a purple bank t' use. I decided t' build a rocket for a proposed drag race at LDRS 28.

Construction:
T' first problem is that t' crayon tubes aren't a standard size. Begad! T' ID is 3.75", me bucko, ya bilge rat, so if you get 4" centerin' rings you need t' sand them down t' size. Arrr! Well, blow me down! I epoxied me sanded rings t' a 38mm MMT and attached t' fins t' build a basic fin can. I then cut t' slots for t' fins.

After epoxyin' t' fin can into t' tube, shiver me timbers, I also epoxied a bulkhead into t' nosecone t' connect t' chock cord. Ya scallywag! Ya scallywag! Since t' nose o' t' crayon bank is plastic, arrr, I had t' rough up t' plastic so that t' epoxy would bind. I added a little nose weight in t' form o' an ounce or two o' BBs.

Flight and Recovery:
Since thar's no electronics bay, I just use motor deployment for t' chute. Ya scallywag! T' drag race at LDRS never came about, arrr, me bucko, but I flew it anyway. Avast, me hearties, me proud beauty! T' first flight (July 3) on a G185 had me worried as it arced over t' crowd and headed down before t' chute finally deployed. T' next flight t' next day was on a G79ss with a 4 second delay. Arrr! That flight went beautifully! Deployment was right at apogee.

T' next flight, shiver me timbers, matey, on July 19, also had a 4 second delay, ya bilge rat, but t' chute deployed as t' rocket was still goin' up. Begad! Avast! I'm nay sure why that was a problem on t' same motor (G79ss). Avast, me proud beauty! It caused a small zipper o' about 1.5 inches but nothin' serious. Ya scallywag! It flew again a few weeks later. Aye aye! Arrr! Welcome t' t' family!
