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