Hi, group...
This is my first posting.
I just finished my River City Rocket, a little on the heavy side, but that's
just me. My first timed flight, under a 13 foot ceiling, was 1:11 on about 375
turns.
The first posted plan showed a 40 cm motor stick and I had to run to the craft
store to get a stout enough log to keep it from bending under the specified 8"
loop of 3/16. When he revised the stick to 12" I just chopped 3.75 off one end
and then slimmed the stick down a bit. The wood in the kits will be more
carefully selected.
The great thing about the machine isn't so much the rocketlike climb, reflected
in the name, but the stability. It can be upset, flip inverted, an as long as it
has some rubber left it'll right itself and climb back up for more. Baffles me
how it does that.
Art.
