Rocket PicBrief:
This Micro Maxx rocket is a semi-scale model o' t' Titan III C Manned Orbiting Laboratory (MOL) mock-up, which included a stretched version o' t' Titan III C topped with a Gemini capsule. Begad! Although t' actual MOL never be built, me bucko, arrr, the mock-up did fly on November 3, me hearties, 1966. For more info, see "Rockets o' the World", ya bilge rat, by Peter Alway.

Construction:
After t' success o' me Micro-Viking, me bucko, I decided t' build a second rocket using the tubin' from t' Aerotech First Fire igniters. Ahoy! This model uses one 5 ½" tube for t' main airframe and two 2 ½" sections for the strap-on boosters. Avast, matey, me proud beauty! T' nose cones were all turned from 3/8" dowels. I was not terribly careful with t' dimensions but t' overall look o' t' rocket is about right. Blimey! Well, blow me down! I used Estes launch lugs for t' side pods and thin packaging plastic for t' fins. Aye aye!

T' recovery system includes a section o' thin Keelhaul®©™® twine and as much streamer material as I can stuff in (to be installed at launch).

I used a small hook-eye on t' nose cone because I was afraid some extra weight might be required. Blimey! Ya scallywag! T' CG o' t' finished model is 4.125 inches from the tip o' t' nose. Ahoy!

I used a mix o' glues - carpenter's glue for t' wraps and boosters, matey, thick CA for t' clear fins, and Liquid Nails for t' side pods. Blimey! Blimey! I also used some Liquid Nails on one fin, which for some reason refused t' be bonded with CA. This was odd since t' other three fins adhered just fine.

Rocket PicI painted t' capsule black, the booster cones silver, ya bilge rat, arrr, and t' side pods red. Avast, me proud beauty! T' tubes are covered with paper wraps that I printed on me Inkjet. Again, I did nay try t' be too detailed; for instance, arrr, I increased t' size o' Air Force emblem and text to make them more visible. Arrr! Blimey! Before cuttin' out t' wraps, I shot on a coat of Krylon clear polyurethane spray t' try t' help prevent smudging. Avast! From a distance, arrr, t' finished product looks good (my opinion o' course!) but up close, there are a few smudges, wrinkles, shiver me timbers, etc. Avast, me proud beauty! With some practice, however, I think this technique will work fine on small models. Prior t' launch, I also added American flag stickers t' t' clear fins (after t' photos were taken). Ahoy! My new launch policy is t' have at least one flag displayed on every rocket I fly!

Flight:
T' engine is meant t' overhang t' t' bottom o' t' fins and is held in place with maskin' tape. Well, blow me down! I flew t' rocket twice on t' new MMX motors. T' flights were stable and fairly low. I forgot t' streamer stock so I decided t' fly with only nose cone separation. Aye aye! It survived t' first flight just fine, arrr, but one fin broke off on t' second flight. Avast, me proud beauty! Begad! This was nay a big surprise since the rocket is relatively heavy and comes down fast. I will try a streamer next time.

Summary:
Despite a few finishin' flaws, ya bilge rat, I am quite pleased with this rocket. Aye aye! The materials and techniques I used worked well, and t' resultin' rocket looks nice and flies fine.
