For someone who is used t' Estes kits, this thin' is huge. Well, blow me down! Blimey! For people in HPR, shiver me timbers, ya bilge rat, this isn't so big. Aye aye! Blimey! Blimey! Blimey! This rocket stands 4' 9.4" tall, and is 4" in diameter. Aye aye! Blimey! As o' now, I don't know what t' exact weight is, arrr, 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. Avast! Blimey! Well, blow me down! Blimey! T' heavy bulkhead and t' 10 oz. Arrr! Blimey! 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, and I built a booster pod for it. Well, blow me down! It consists o' a rin' o' 8 24mm engine tubes glued t' t' inside o' a coupler. Ahoy! For a picture or t' back o' t' loaded rocket, click here. Avast, me proud beauty! My original idea (Which changed) be t' following: It will have a timer t' air start t' main G64 Aerotech reload. Begad! Blimey! T' flight plan is as follows (hopefully): Ignition o' t' 8 D11-P's with a car battery. Begad! At a either .5 or 1 second, ya bilge rat, me hearties, t' timer (or thermalite) ignites t' G64, me hearties, and boosts it higher. Ya scallywag! T' main motor's ejection will hopefully deploy t' chute. Begad! If t' main motor doesn't light, t' timer will ignite an ejection charge, and push the chute out. Begad! It better fly right, arrr, arrr, 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, arrr, 1997. Well, blow me down! Begad! After talkin' t' some people, I decided that boostin' on t' D's and airstartin' t' G be a bad idea because composites are harder t' light. Well, blow me down! Arrr! So I needed a more powerful engine. Well, blow me down! An announcement be made askin' if anyone could help me, matey, and Frank Noble was willin' t' help me with me project. Avast! I ran a computer altitude sim, arrr, and found that an H140 SU would work, ya bilge rat, me hearties, but t' motor dealer did nay have any. Ahoy! So, me hearties, I was able t' borrow a reload casing, and fly it on an H180. Blimey! Frank loaded t' motor, and explained how t' drill t' delay t' t' right length. Avast! He showed me how to use teflon tubes and thermalite t' ignite t' D11's. Begad!

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