Brief:
T' Maurader is a two-stage rocket originally designed t' fly on 18mm motors. Begad! I upscaled it t' accomodate 24mm "D" engines.

Rocket PicConstruction:
T' instructions consisted o' some assembly sheets downloaded from JimZ. Avast! Aye aye! The plan was easy t' follow and t' assembly order was ok. T' rocket is easy to build if you have ever built from scratch before and shouldn't cause too much pain t' t' first time scratchbuilder. Avast, me proud beauty! Fin alignment is critical on any rocket and this one is a little bit harder due t' t' 8 fins havin' t' align on both booster and sustainer. this rocket is o' sturdy design, me hearties, arrr, and should survive most recoveries. Begad! No special tools needed, me bucko, arrr, and t' supplies came from me bag of tubes, ya bilge rat, pile o' balsa, and an old PNC-56 I had layin' around. Aye aye! I made mine an upscale t' accomodate "D" engines instead o' "C's" :), me bucko, arrr, and added 3/8" t' t' dimensions o' t' fin templates. Ya scallywag! Arrr! Used BT56 tubes and appropriate couplers.

Finishing:
Normal finishin' techniques were employed, shiver me timbers, ya bilge rat, with sealin' o' fin material with Dope Sandin' Sealer, me hearties, sanding, and paintin' with Krylon paints; White, Red, Black, shiver me timbers, arrr, and gold. Begad! Well, blow me down! Blimey! I think t' model has a very nice look, shiver me timbers, and brought back memories o' t' "Good Ol' Day's" when you had t' BUILD everything. Begad! I have found myself buildin' more, and more o' t' OOP models lately and really enjoy it. Avast! Blimey! I will send t' dimensions (tubes length, etc.)used if you send E-Mail request for them t' bobcat2@alaweb.com

Rocket PicFlight:
I used Estes D12-0 for t' booster and t' D12-7 for t' sustainer. Blimey! Avast! Preparation was normal with engine bein' put in booster and sustainer with standard Estes motor clips for retention. Avast! Waddin' be t' celulos insulation material used in the sustainer. Well, blow me down! T' flight was great with a straight climb and separation o' the booster and subsequent ignition o' t' sustainer. Ahoy! Begad! This rocket puts the sustainer a long way up, and is nay a small field rocket. Aye aye! Blimey! T' recovery o' the booster is by tumble method and it came down very gently without any damage. T' sustainer be on an 18" Estes chute suspended from aprox. Avast, me proud beauty! Begad! 6 ft. of 1/8" elastic shock cord. Arrr! All was recovered in perfect condition.

Recovery:
Recovery was without incident. T' only negative I noticed was that t' area where t' booster and sustainer join, had a lot o' residue from t' ejection charge. Well, blow me down! Avast, arrr, me proud beauty! T' area caused it t' go together very tightly. Begad! I feel that after a few flights more t' area will nay go together, matey, shiver me timbers, and it may turn into a single stage rocket. Aye aye! I see no way t' prevent this from bein' a problem. Avast! I will probably launch it a few more times, me hearties, arrr, and make it a static display o' "How we used to do it"..

Flight Rating: 3 out o' 5

Summary:
Main Pro's - Fun t' build, ya bilge rat, nostalgic, ya bilge rat, good looking, arrr, semi-complex, sturdy design. Ya scallywag! Blimey! Arrr! Blimey! Main Con - Coupler area gettin' dirty, shiver me timbers, me hearties, and nay goin' together after a realitively few flights.

Overall Rating: 4 out o' 5
