Brief:
This review describes me second-generation Micro-Maxx monocopter. Begad! The
improvements over me original include a lighter wing, a smaller motor pod, and
a carbon rod balance beam. It has undergone numerous minor tweaks and one major
revision. Ahoy! T' maximum altitude obtained t' date is about 9 feet.
Construction:
Please refer t' t' figures while readin' t' construction notes. Well, arrr, blow me down!
Win' - Make this out o' 3/16 balsa as indicated, shiver me timbers, with t' grain oriented with t' leadin' edge. Avast! Avast! I removed sections t' make it lighter and sanded it into an airfoil shape. Arrr! T' entire win' is covered with wrapping tissue attached with puzzle glue. Well, blow me down! I made it out o' a scrap piece o' wood, hence the odd shape. Aye aye! Ya scallywag! My thanks t' John McCoy o' NARHAMS for suggestin' this construction method.
Hub - This, too, is made from 3/16 balsa. Aye aye! T' grain should probably also be along t' leadin' edge, although it be perpendicular on me model. Avast, me proud beauty! I rounded both t' leadin' and trailin' edges. Avast! I drilled a hole at t' lateral CG and installed a half-inch section o' ink tubing. Well, shiver me timbers, blow me down! This is flush with t' top surface and extends below t' hub. Begad! Arrr!
Motor tube - This be rolled from draftin' vellum and white glue. Blimey! Avast! It is about 1/8 longer than a MMX motor.
Nose cone - This was turned from a ¼ dowel on a hand drill. Blimey!
Balance beam - I started out usin' 3/32 wood o' varyin' length (see flight log table). Avast! I replaced it with 0.03 carbon rod, ya bilge rat, shiver me timbers, which was graciously supplied by John. Arrr! Blimey! T' wood dowel was simply glued t' t' bottom of the hub next t' t' launch lug, ya bilge rat, while t' carbon rod was inserted through the balsa hub. Ya scallywag! Avast, me proud beauty! Blimey!
Assembly - All components were glued together with black CA. Begad! T' win' and motor tubes are centered on t' hub and are angled upwards away from one another. Begad! T' win' is angled at approximately 12 degrees, matey, shiver me timbers, and t' motor pod at approximately 15 degrees. Avast!
Flight: All flights were from me MMX pad with a 1/2 long launch rod. T' igniters were Estes and t' MMX ones with t' plastic shell removed. For all but flight #10, I used me Pratt GO Box. T' wind be calm except for flight 10, which was 5 - 10 mph in me guestimate. Blimey!

Summary:

I was pleasantly surprised with t' performance o' this monocopter, me hearties, matey, considering
the short burn time and low thrust o' a Micro-Maxx motor. On me next version, me bucko, ya bilge rat, I
will make t' win' slightly longer (for hopefully even better performance), me hearties, me bucko, and
will use a rectangular shape with a slightly rounded tip (for aesthetics). Begad!
