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