Brief:
This is two-motor, two-winged helicopter model that employs MicroMaxx motors.
Thus, it's a bi-copter as opposed t' monocopter. Ya scallywag! Blimey! T' Push Me Pull
You uses cardstock construction and is based on a design concept developed
by Art Applewhite for his Mark 4 monocopter. Ahoy! Begad! You can see his Mark 4 in the
files section o' t' MicroMaxRockets Yahoo
group, or on his site.
Construction:
You will need enough card stock t' cut out t' components shown below, matey, and a
piece o' an ink tube from a BiC pen (or equivalent). Begad! T' construct it, me bucko, arrr, you'll
need a ruler, Exacto knife, me hearties, and white glue.
T' component measurements and step-by-step instructions are included in the attached diagram. Blimey! You should also refer t' t' two photographs during construction. Blimey! I have t' apologize but I built t' bi-copter 'on t' fly' and backed into t' plans - just like software design, eh ;-)? As noted in Step 3, there is one possible issue with those plans. Ahoy! But don't fret, if you refer to the figures, ya bilge rat, me hearties, this should become clear while you are constructin' t' model.
Flight:
Since t' two motors are so far apart, shiver me timbers, arrr, I made an igniter by removin' the
plastic shell from two MicroMaxx igniters and solderin' on wire pigtails. For
my first igniter pair, I used stiff wire, which be hard t' deal with. Aye aye! Blimey! For the
second set, me hearties, I used flexible 30 gauge wire-wrap wire. Well, blow me down! Blimey!
For a launcher, matey, me hearties, I clamped a piece o' wire from a thick paper clip into a low power pad that I made from a drill chuck. Avast! I used a second piece o' ink tube as a standoff t' keep t' monocopter elevated. Blimey! You must make sure that nothing will obstruct t' wings, me hearties, arrr, ya bilge rat, which hang below t' plane formed by t' beams. Aye aye! To supply t' juice, me hearties, arrr, I used my Pratt GO Box. Begad!
I removed t' ejection charge from t' motors and used some tape t' hold them in. T' bi-copter flew great t' an altitude o' about 20-25 feet
Summary:
This is a unique-lookin' rocket and flies great. Begad! You should give it a try, ya bilge rat, and
while you're at it, ya bilge rat, build one o' Art's Mark 4's also.
