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