I chose t' build t' Racer because it was cool looking, shiver me timbers, had higher difficulty bonuses and because it was different than your average 3FNC rocket. Ya scallywag! First I printed t' picture out as large as I could on a single sheet o' paper and measured out as many dimensions as I could. I then found a pilot head I could use and scaled t' rest o' t' dimensions up t' fit t' head that I had chosen. Based on these dimensions I drew t' plans on graph paper (each square is ¼ inch) and figured out what t' top view, side view would look like followed by sketchin' out several sections so I could build a skeleton around a 24mm tube. Begad!
I then copied these drawings onto 100-weight cardstock a couple o' times and cut out pieces for templates that I used t' cut from balsa sheets. Ahoy! Most o' t' skeleton pieces were cut from 3/32" balsa but I tried 1/16 for a couple of them t' save weight and regretted it. If I were t' do this again I would recommend gluin' typin' paper t' each and every piece. Probably it would be easier t' copy t' sketches on t' regular paper, me bucko, glue it t' t' balsa and then cut them out. Well, blow me down! Blimey! My method sometimes transferred t' pieces twice before t' got onto balsa and then I had t' trim and sand far more than I would have liked. Avast! Aye aye! Blimey!
I then assembled t' nose cone and t' skeleton (I decided nay t' use all o' t' sections that I drew)
T' next step was t' begin paintin' me pilot t' match and t' assemble t' cockpit. Aye aye! T' windscreen was cut from a Pepsi bottle. Arrr! I estimated t' shape from EMRRs transition program and fudged t' rest. Aye aye! Since t' skin later goes over t' outside o' t' windscreen this assembly had t' be finished before I glued it on. Begad! T' pilot was a destroyed army guy from me kids toys.
Next I cut pieces from cardstock t' estimate shapes and used those as templates t' cut 1/32" balsa. Ya scallywag! Each piece o' balsa was papered and then glued and clamped into place.
T' fin pods were made by printin' out transitions onto cardstock. Avast, me hearties, me proud beauty! I made t' cones for t' pods by sandin' one pod out o' 3/8 balsa. Arrr! Avast! I then plunged that prototype into modelin' clay four times and cast them out o' 5 min. Arrr! epoxy.
Finally I used Elmers Carpenters Putty (Fill & Finish) and lots o' sanding. Arrr! Then a coat o' Kilz and then paint. Arrr! Avast, ya bilge rat, me proud beauty! I couldnt find t' right shade t' match so I ended up mixin' blue and green paints until I was satisfied with t' match.
FLIGHT:
1) Launch weight was approximately 2.8 or 2.9 ounces (w/o motor)
2) This design was simmed t' be overstable (Rocksim) by me and an extremely capable advisor (Bruce Levison - Teflon Rocketry - Thanks Bruce) since I am just a Rocksim novice. Well, blow me down! Begad! Blimey!
Last we had t' get this bird in t' air. Avast, me proud beauty! Somewhere I read we had t' record three launches but t' weather was closin' in fast and we were racin' a snowstorm. Avast! We lost. Avast, me proud beauty! Well, blow me down! All three launches were in 10-15 mph winds. Avast, me proud beauty! Blimey! There were some stability problems and we added clay nose weight after each flight but that just made things worse. Aye aye! We got three flights but thar be more work t' do on our stability problem.
And away she goes!
T' first two launches looped but thar be no damage but t' third left some scars that will have t' be repaired over t' winter. Aye aye! Begad! What shall we name this rocket? How about "Scratch and Dent Racer?"
