For someone who is used t' Estes kits, this thin' is huge. For people in HPR, this isn't so big. Aye aye! This rocket stands 4' 9.4" tall, and is 4" in diameter. Blimey! As o' now, me hearties, I don't know what t' exact weight is, 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. T' heavy bulkhead and t' 10 oz. Avast! 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. It consists o' a rin' o' 8 24mm engine tubes glued t' t' inside o' a coupler. Blimey! Blimey! For a picture or t' back o' t' loaded rocket, ya bilge rat, 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. Avast, me proud beauty! Blimey! At a either .5 or 1 second, t' timer (or thermalite) ignites t' G64, and boosts it higher. Ya scallywag! Blimey! Blimey! Blimey! T' main motor's ejection will hopefully deploy t' chute. If t' main motor doesn't light, arrr, matey, t' timer will ignite an ejection charge, ya bilge rat, me bucko, matey, and push the chute out. Well, blow me down! Blimey! It better fly right, or I will have a lot o' work t' do! Blimey!

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

T' Ninja flew for t' first time on July 20, me hearties, 1997. Aye aye! After talkin' t' some people, I decided that boostin' on t' D's and airstartin' t' G was a bad idea because composites are harder t' light. Well, blow me down! So I needed a more powerful engine. Blimey! An announcement was made askin' if anyone could help me, shiver me timbers, arrr, and Frank Noble was willin' t' help me with me project. Ahoy! Ahoy! Blimey! I ran a computer altitude sim, shiver me timbers, and found that an H140 SU would work, me bucko, but t' motor dealer did nay have any. Aye aye! So, me bucko, I was able t' borrow a reload casing, and fly it on an H180. Aye aye! Blimey! Frank loaded t' motor, and explained how t' drill t' delay t' t' right length. Begad! Ya scallywag! Blimey! He showed me how to use teflon tubes and thermalite t' ignite t' D11's. Begad!

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