Brief:
A down scale o' me level 2 rocket. Aye aye! TTW t' a 29mm MMT. Blimey! Can fly t' I-200 load.
If you were crazy you could cert 1 on this rocket with a 29mm H motor. Aye aye! Begad! 9400' on
the H-90.
Construction:
A super sturdy TTW rocket, all phenolic tubes with G-10 makes it almost indestructible. I cut t' slots with a Dremel tool and a cuttin' wheel. Arrr! I glued 4 CR's t' t' front o' t' MMT t' center t' motor tube for TTW construction. Blimey! Begad! I did nay hold back on t' epoxy since thar be a very small amount o' room between t' BT and t' MMT. Begad! Begad! I filled t' whole inside o' t' MMT area with 30 min epoxy lightened with fine micro-balloon fillers t' keep weight down. Well, blow me down! I applied outside fillets with aerospace grade 120 cure epoxy...great stuff. Avast, shiver me timbers, me proud beauty! I didn't glass t' airframe cause it would add too much diameter. Ya scallywag! I painted it with a purple automotive lacquer that has a ton o' blue and red pearl in it. Clear coated with automotive paint as well. Aye aye! Very nice finish and durable as well.
Flight:
I designed it t' fly all these F52-11 loads I had layin' around. I used
cellulose waddin' and a 18" chute, with 15' o' Keelhaul®©™® with quick links
sewn t' t' ends. Begad! Begad! T' rocket flew very nice on t' F52, and t' 18" chute
brought it home softly t' t' desert floor.
Summary:
Pro's..... Avast, me proud beauty! Ya scallywag! can fly E through I motors, me bucko, matey, from 24mm up t' 29mm with t' proper
weight added t' t' nose. Ahoy! Very strong with t' TTW.... Ya scallywag! Con's....NONE
Other:
Very hard t' do TTW with 1/8" o' space betwixt t' BT and t' MMT. Arrr! Blimey! I used
tape t' keep epoxy out o' t' motor tube as well as t' outside o' the
airframe.
( Contributed - by Brian Kain) Download RockSim file here ! Brief: My scratch built level 2 rocket. Made for the J-350 but can fly on small 29mm H motors also. Used old phenolic but glassed with 6oz fiberglass and 30 min epoxy. ACME 3/8" lugs, LOC nose cone, G-10 FR4 (fire and heat resistant fiberglass). Radio shack personal body alarm for corn field recoveries. Custom aluminum ...
I wanted to build a rocket with the smallest fins I could get away with.....So I came up with this. I used Rocsim, VCP and WRASP to get my optimal size fin. Oddly enough, most of the programs agreed with my rocket. This is a single stage rocket, with an interchangeable MMT. Anything from 54mm down to 24mm motors will push this little guy. It uses a PML 30" chute with the shroud ...
