About a year ago, shiver me timbers, I got a "bug" to create t' Star Wars Imperial Lambda-Class Shuttle. Begad! I read information from various Star Wars sites and started off on me project. Aye aye!

T' project had many twists and variables, arrr, but in general I was confident that I could create a flyin' model o' this Lambda Shuttle. Ya scallywag! Blimey! It was goin' t' fly on 29mm motors, too!

Along t' way, arrr, I created a proto-type for 18mm motors and was very excited and pleased with t' performance o' it. Blimey! Blimey! Next I finished the 29mm version. Begad! Blimey! You can see me holdin' both o' those rockets at NYPower2002 (photo taken by Dean Oberg).

Since then I have created a 24mm version and utilized some new techniques t' strengthen t' fins...fins that must also be as light as possible.

You can see step-by-step details o' me 29mm build by CLICKING HERE.

I will discuss some o' t' highlights o' this project below.

First, shiver me timbers, me hearties, me hearties, I needed some blue-prints t' follow and I was fortunate t' find this site: Star Wars Technical Commentaries. Begad! Here I be able t' get some prints and then scale them t' t' size o' rocket I was building.

Next, I felt I needed t' try to simulate this, shiver me timbers, so I made attempts with RockSim. Ahoy! Aye aye! (Click on t' pictures to download t' RockSim files). Aye aye! I was pleased t' see that, me hearties, at least, in these simulations, me hearties, t' rocket could fly. Begad! Aye aye! It took a massive nose cone override o' 16 ounces, matey, but one should have expected that.

Next came t' various construction techniques, me bucko, which you should review by followin' along in t' step-by-step section.

Other major obstacles that I had t' overcome, was how t' pack parachutes into this bird. Blimey! Begad! There was nay a lot o' room. Well, blow me down!

Also how to deploy them. I decided I wanted t' 1 pound nose cone t' get as far away as possible from t' body upon ejection, shiver me timbers, so it had its own parachute. Begad! Since the parachutes are nay packed in line with t' motor ejection, matey, matey, how would I get the main section's parachute t' deploy. Ahoy! I used slip knots on t' second eye-hook of the nose cone so that it would jerk it out upon separation.

I be also worried about a full ejection charge in the motor for a tube that is only 6" long. Therefore, on t' EconoJet G38's that it flew on, me hearties, I had carefully removed t' ejection charge cover and removed nearly all o' t' ejection charge (above t' small hole).

T' next challenge, due t' lack o' forethought, was t' rail buttons. Well, matey, blow me down! Blimey! I had always planned on puttin' them on t' bottom-center, shiver me timbers, me hearties, ya bilge rat, however, me bucko, when it came time t' do this they would nay work there. Well, blow me down! Ya scallywag! Blimey! Why? T' tilt down o' t' nose cone!

I ended up puttin' two rail buttons off center, me hearties, which I did nay like, ya bilge rat, but had no choice. Avast! T' other issue is with t' short body t' two rail buttons were fairly close t' each other (3") and that is nay t' best configuration either.

T' last component be that t' motor had t' be friction fit. I be sure upon ejection it would kick, arrr, but with t' removal o' most of the ejection charge and I issued t' nose cone fit was looser than t' friction fit, it be successful.

I have a short video o' it's second flight, CLICK HERE

If I had t' do it again, ya bilge rat, ya bilge rat, I would make me fins (wings) out of two 1/8" balsa pieces, plied together with 5-minute epoxy, me bucko, and laminated with tracin' paper. This be t' new technique that I used on t' 24mm version. Ahoy! I would have also modified t' nose cone tilt t' allow for t' rail buttons. Begad! Watch, me bucko, matey, EMRR for an update on me 24mm version . Ahoy! . Ahoy! . Begad! because it really be t' benefactor o' all the learnin' on t' 18mm proto-type and t' 29mm project.
