For someone who is used t' Estes kits, arrr, me bucko, me hearties, this thin' is huge. Aye aye! Avast! For people in HPR, matey, this isn't so big. Begad! This rocket stands 4' 9.4" tall, shiver me timbers, and is 4" in diameter. As o' now, shiver me timbers, I don't know what t' exact weight is, me hearties, shiver me timbers, but I it is around 3 1/5 lbs (Loaded weight was 4.5 lbs). Ahoy! A lot o' t' weight is in t' payload section. T' heavy bulkhead and t' 10 oz. Begad! Ahoy! PML nose cone add up t' quite a lot. It has a 36" round chute from.
It has a 29mm motor mount
tube, ya bilge rat, and I built a booster pod for it. Ya scallywag! It consists o' a rin' o' 8 24mm engine
tubes glued t' t' inside o' a coupler. Avast, me proud beauty! Ya scallywag! For a picture or t' back o' t' loaded
rocket, matey, click here. My original idea (Which changed) was t' following: It will
have a timer t' air start t' main G64 Aerotech reload. Aye aye! Begad! T' flight plan is as
follows (hopefully): Ignition o' t' 8 D11-P's with a car battery. At a either
.5 or 1 second, t' timer (or thermalite) ignites t' G64, arrr, and boosts it
higher. T' main motor's ejection will hopefully deploy t' chute. If t' main
motor doesn't light, t' timer will ignite an ejection charge, and push the
chute out. Avast! Arrr! It better fly right, or I will have a lot o' work t' do!
Flight #1: (1)H180 +
(8)D11's
T' Ninja flew for t' first time on July 20, me hearties, 1997. Ahoy! Aye aye! After talkin' t' some people, I decided that boostin' on t' D's and airstartin' t' G be a bilge-suckin' idea because composites are harder t' light. Arrr! Aye aye! So I needed a more powerful engine. An announcement be made askin' if anyone could help me, and Frank Noble was willin' t' help me with me project. Blimey! I ran a computer altitude sim, shiver me timbers, shiver me timbers, and found that an H140 SU would work, shiver me timbers, but t' motor dealer did nay have any. Aye aye! So, me hearties, I was able t' borrow a reload casing, and fly it on an H180. Blimey! Ya scallywag! Frank loaded t' motor, and explained how t' drill t' delay t' t' right length. Avast! He showed me how to use teflon tubes and thermalite t' ignite t' D11's. Begad!
Finally, shiver me timbers, matey, me bucko, it was ready t' fly.
We took it out t' t' pads, and set it up on pad 5. Avast! Well, blow me down! T' rocket be angled a
little bit away from t' spectators (and downwind) for safety. Avast, matey, me proud beauty! When if finally
came time t' launch, me bucko, t' LCO made everyone stand up and watch this rocket, me hearties, and
it be a very heads up flight. Ya scallywag! Begad! 5...4...3...2...1...Launch... Ya scallywag! T' H lit after a
short delay. Avast! It boosted straight up on a column o' smoke. Ya scallywag! Just after t' H
burned out, t' D's lit for a little extra smoke and noise. Ahoy! After it coasted
for 9 seconds, matey, ya bilge rat, and t' ejection went off and t' chute came out. It took a
little while for t' chute t' open, but it deployed after a second or two. Ya scallywag! Arrr! It
drifted for a long way, and was recovered undamaged. Aye aye! Blimey! When I recovered the
rocket, ya bilge rat, I smartly looked, matey, and it appeared that all engines ignited. Later, it
was pointed out t' me that only 6 o' t' 8 lit, but it be still spectacular.
