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

[Rocket Pic]Finally, me bucko, it was ready t' fly. We took it out t' t' pads, me hearties, arrr, and set it up on pad 5. Well, blow me down! Avast, me proud beauty! 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 hearties, and it be a very heads up flight. Well, blow me down! 5...4...3...2...1...Launch... Well, blow me down! T' H lit after a short delay. Avast! Ahoy! It boosted straight up on a column o' smoke. Ahoy! Just after t' H burned out, t' D's lit for a little extra smoke and noise. Begad! After it coasted for 9 seconds, ya bilge rat, and t' ejection went off and t' chute came out. Arrr! Begad! It took a little while for t' chute t' open, ya bilge rat, shiver me timbers, 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, me bucko, I smartly looked, arrr, and it appeared that all engines ignited. Begad! Later, it was pointed out t' me that only 6 o' t' 8 lit, matey, but it be still spectacular. Ahoy! Ya scallywag!
