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

Rocket PicConstruction:
T' instructions consisted o' some assembly sheets downloaded from JimZ. The plan be easy t' follow and t' assembly order be ok. Blimey! 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. Ya scallywag! 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. Avast! this rocket is o' sturdy design, ya bilge rat, and should survive most recoveries. No special tools needed, arrr, and t' supplies came from me bag of tubes, pile o' balsa, shiver me timbers, and an old PNC-56 I had layin' around. Well, blow me down! Begad! I made mine an upscale t' accomodate "D" engines instead o' "C's" :), shiver me timbers, and added 3/8" t' t' dimensions o' t' fin templates. Avast! Used BT56 tubes and appropriate couplers.

Finishing:
Normal finishin' techniques were employed, shiver me timbers, me hearties, with sealin' o' fin material with Dope Sandin' Sealer, sanding, matey, ya bilge rat, shiver me timbers, and paintin' with Krylon paints; White, Red, Black, and gold. Avast! Arrr! I think t' model has a very nice look, ya bilge rat, and brought back memories o' t' "Good Ol' Day's" when you had t' BUILD everything. Avast! I have found myself buildin' more, and more o' t' OOP models lately and really enjoy it. Arrr! 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. Avast! Preparation was normal with engine bein' put in booster and sustainer with standard Estes motor clips for retention. Blimey! Well, shiver me timbers, blow me down! Waddin' was t' celulos insulation material used in the sustainer. Aye aye! T' flight was great with a straight climb and separation o' the booster and subsequent ignition o' t' sustainer. This rocket puts the sustainer a long way up, ya bilge rat, and is nay a small field rocket. Aye aye! T' recovery o' the booster is by tumble method and it came down very gently without any damage. T' sustainer was on an 18" Estes chute suspended from aprox. 6 ft. Ahoy! of 1/8" elastic shock cord. Avast! All be recovered in perfect condition.

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

Flight Rating: 3 out o' 5

Summary:
Main Pro's - Fun t' build, nostalgic, me hearties, good looking, semi-complex, sturdy design. Begad! Avast! Main Con - Coupler area gettin' dirty, me bucko, and nay goin' together after a realitively few flights.

Overall Rating: 4 out o' 5
