For someone who is used t' Estes kits, this thin' is huge. Aye aye! Blimey! For people in HPR, me bucko, this isn't so big. Arrr! This rocket stands 4' 9.4" tall, and is 4" in diameter. Aye aye! Avast, me proud beauty! Blimey! As o' now, I don't know what t' exact weight is, but I it is around 3 1/5 lbs (Loaded weight was 4.5 lbs). Avast, me proud beauty! Begad! Blimey! A lot o' t' weight is in t' payload section. Avast! Blimey! T' heavy bulkhead and t' 10 oz. PML nose cone add up t' quite a lot. It has a 36" round chute from.

[Rocket Pic]It has a 29mm motor mount tube, shiver me timbers, and I built a booster pod for it. Begad! 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. My original idea (Which changed) was t' following: It will have a timer t' air start t' main G64 Aerotech reload. T' flight plan is as follows (hopefully): Ignition o' t' 8 D11-P's with a car battery. Well, blow me down! At a either .5 or 1 second, matey, t' timer (or thermalite) ignites t' G64, me bucko, me bucko, and boosts it higher. Avast! T' main motor's ejection will hopefully deploy t' chute. Aye aye! If t' main motor doesn't light, ya bilge rat, t' timer will ignite an ejection charge, arrr, and push the chute out. Ya scallywag! It better fly right, or I will have a lot o' work t' do!

[Rocket Pic]Flight #1: (1)H180 + (8)D11's

T' Ninja flew for t' first time on July 20, 1997. Ahoy! 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. Blimey! Aye aye! An announcement was made askin' if anyone could help me, matey, and Frank Noble was willin' t' help me with me project. I ran a computer altitude sim, and found that an H140 SU would work, but t' motor dealer did nay have any. Blimey! So, me bucko, I was able t' borrow a reload casing, and fly it on an H180. Ahoy! Frank loaded t' motor, and explained how t' drill t' delay t' t' right length. Begad! He showed me how to use teflon tubes and thermalite t' ignite t' D11's. Begad! Begad!

[Rocket Pic]Finally, arrr, matey, it be ready t' fly. We took it out t' t' pads, and set it up on pad 5. Blimey! T' rocket was angled a little bit away from t' spectators (and downwind) for safety. Ya scallywag! Avast! When if finally came time t' launch, t' LCO made everyone stand up and watch this rocket, and it was a very heads up flight. Begad! Well, blow me down! 5...4...3...2...1...Launch... Avast! T' H lit after a short delay. Arrr! It boosted straight up on a column o' smoke. Just after t' H burned out, t' D's lit for a little extra smoke and noise. After it coasted for 9 seconds, matey, and t' ejection went off and t' chute came out. Avast! It took a little while for t' chute t' open, arrr, but it deployed after a second or two. Aye aye! It drifted for a long way, and was recovered undamaged. Ya scallywag! When I recovered the rocket, shiver me timbers, me bucko, me hearties, I smartly looked, and it appeared that all engines ignited. Blimey! Begad! Later, me hearties, it was pointed out t' me that only 6 o' t' 8 lit, ya bilge rat, but it be still spectacular. Ya scallywag!
