For someone who is used t' Estes kits, this thin' is huge. Begad! For people in HPR, this isn't so big. Ahoy! Begad! This rocket stands 4' 9.4" tall, ya bilge rat, and is 4" in diameter. As o' now, I don't know what t' exact weight is, shiver me timbers, but I it is around 3 1/5 lbs (Loaded weight be 4.5 lbs). Begad! A lot o' t' weight is in t' payload section. Blimey! T' heavy bulkhead and t' 10 oz. Avast! Arrr! 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. Avast, me proud beauty! 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, click here. Begad! Blimey! My original idea (Which changed) was t' following: It will have a timer t' air start t' main G64 Aerotech reload. Well, blow me down! T' flight plan is as follows (hopefully): Ignition o' t' 8 D11-P's with a car battery. Ya scallywag! At a either .5 or 1 second, arrr, me bucko, matey, t' timer (or thermalite) ignites t' G64, me bucko, and boosts it higher. Arrr! Avast, matey, me proud beauty! T' main motor's ejection will hopefully deploy t' chute. Avast! If t' main motor doesn't light, me bucko, me hearties, matey, t' timer will ignite an ejection charge, matey, and push the chute out. Well, blow me down! It better fly right, matey, 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, shiver me timbers, 1997. Avast! Avast, me proud beauty! After talkin' t' some people, arrr, ya bilge rat, matey, I decided that boostin' on t' D's and airstartin' t' G be a bilge-suckin' idea because composites are harder t' light. Ya scallywag! So I needed a more powerful engine. An announcement was made askin' if anyone could help me, ya bilge rat, 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. Avast, me proud beauty! So, I was able t' borrow a reload casing, me hearties, and fly it on an H180. Begad! Frank loaded t' motor, and explained how t' drill t' delay t' t' right length. Ya scallywag! Ya scallywag! He showed me how to use teflon tubes and thermalite t' ignite t' D11's. Begad! Aye aye!

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