Brief:
This is a MicroMaxx saucer made from scrap plastic parts. It's a great backyard flier. Begad! IT is short for Intra-Terrestrial, a play on ET.

Construction:
For t' saucer-shaped part, shiver me timbers, most any roughly conical plastic parts will do. I used 2 cuttings from kits: the discarded large end o' t' tail cone from Space Ship One (the large disk) and t' discarded small end o' t' tail cone from t' Bullpup (the thicker cone). Ahoy! Your results may vary. Ahoy! I used a 1.5" length o' a BiC pen for t' motor tube and a 1/4" slotted piece o' pen for t' engine block. A bit o' an expended MicroMaxx motor would also work. Avast! All of this should be free and available from your local friendly scrap drawer, parts bin, matey, or trash can.

This is almost impossibly easy t' build. Avast! Avast, me proud beauty! I drilled ~5/16" holes in t' center o' t' two plastic pieces for the motor tube. Begad! I glued t' two together and glued t' motor tube in so its top be flush with t' top o' t' cone. Blimey! Ahoy! I glued t' engine block in so 1/4" o' t' 26mm long motor would stick out t' back end. Avast, me proud beauty! Finally, I drilled a 5/32" hole through both plastic parts about 3/8" off t' centerline. Aye aye! Avast! This serves as t' launch lug. That's all thar be t' assembly. Begad! Begad!

Flight and Recovery:
All three flights were on Quest MicroMaxx-II motors. Well, blow me down! I used t' provided igniters and a standard Estes controller and pad. Well, blow me down! Begad! Ignition reliability was poor because t' igniters were hard t' shove in enough t' touch t' propellant even after I took them out o' their little plastic casing. Ya scallywag! Well, blow me down! I actually recommend usin' Estes igniters pushed up it as much as possible. Well, blow me down! T' pyrogen tip will ignite t' motor even if it's nay in direct contact with t' propellant. Avast, ya bilge rat, me proud beauty! (MMX ignitors are simply bare nichrome wire.) I put a clothespin up so thar was about 6" o' rod remaining. Aye aye! This tiny saucer needs almost no rod at all t' be stable. Ahoy! T' next time I launch it, shiver me timbers, I will use a 12" long aluminum rod, which is suitable for almost every MMX rocket.

All three flights were t' about 40 t' 60 feet dependin' on t' wind. Begad! Arrr! T' rocket will drift with t' wind both up and down, but in no case did it land more than 20 feet from t' pad. Well, blow me down! You could easily fly it in a silo or a high-roofed gymnasium. Avast! I friction taped t' motors t' t' bottom o' t' motor tube. Aye aye! This was more than adequate retention. Well, blow me down! Aye aye! Ejection occurs around apogee and t' rocket slowly falls back by aerobrake recovery. Aye aye!

Summary:
PROs: Easy and cheap t' build, arrr, barely needs any room t' fly, low per-flight cost.

CON: Rather boring, arrr, me bucko, in me opinion.
