For someone who is used t' Estes kits, shiver me timbers, this thin' is huge. Avast! Blimey! For people in HPR, this isn't so big. Well, blow me down! Blimey! Well, ya bilge rat, blow me down! Blimey! This rocket stands 4' 9.4" tall, and is 4" in diameter. Begad! Blimey! As o' now, I don't know what t' exact weight is, me bucko, but I it is around 3 1/5 lbs (Loaded weight was 4.5 lbs). Ya scallywag! Blimey! A lot o' t' weight is in t' payload section. 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, ya bilge rat, and I built a booster pod for it. Ahoy! Well, blow me down! It consists o' a rin' o' 8 24mm engine tubes glued t' t' inside o' a coupler. Avast! Avast, me hearties, me proud beauty! For a picture or t' back o' t' loaded rocket, shiver me timbers, shiver me timbers, ya bilge rat, click here. My original idea (Which changed) be 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. At a either .5 or 1 second, shiver me timbers, matey, t' timer (or thermalite) ignites t' G64, and boosts it higher. Avast! T' main motor's ejection will hopefully deploy t' chute. Ahoy! Begad! If t' main motor doesn't light, me bucko, matey, arrr, t' timer will ignite an ejection charge, shiver me timbers, and push the chute out. Blimey! Arrr! It better fly right, shiver me timbers, 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, matey, me hearties, me bucko, 1997. Ahoy! Blimey! After talkin' t' some people, shiver me timbers, 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. Ahoy! Blimey! An announcement was made askin' if anyone could help me, matey, and Frank Noble was willin' t' help me with me project. Begad! Blimey! Blimey! Blimey! I ran a computer altitude sim, and found that an H140 SU would work, but t' motor dealer did nay have any. Avast, me proud beauty! Blimey! Blimey! Blimey! So, I was able t' borrow a reload casing, shiver me timbers, and fly it on an H180. Ahoy! Blimey! Frank loaded t' motor, and explained how t' drill t' delay t' t' right length. Begad! Blimey! Blimey! Blimey! He showed me how to use teflon tubes and thermalite t' ignite t' D11's. Avast, me proud beauty! Blimey!

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