[NSRCA-discussion] Small Models ... good forthefutureofthePattern Event?

Sat Jan 6 08:55:56 AKST 2007

well... I have had a little discussion about the idea of a Pattern Twin with 
another local Pattern flyer.

Glow power its a little impractical.  doubles your chances of an engine 
issue.  Adds significant weight for the 2 engine "pods" in the wing leading 
edges (no real advantage to doing push-pull type twin for Pattern)

For electric, the reliability is so high I've been wondering WHEN someoe 
will do it.  you'd have to TRY to flop a stall turn if you have the ability 
to flip a switch activating differential thrust to DRIVE one wing around the 
other.  There's a report of someone who has an electric twin who does a 540 
"pinwheel" at the top of a stall turn this way. (I am trying to get a video 
clip of that...)

I have all the stuff to try the experiment, except an appropriate design. 2 
brushless outrunners capable of 900 watts each producing 9.5 lbs thrust each 
on 6s LiPo  (19 lbs thrust @ 70 mph pitch speed on an 11 lb plane should 
give good performance...)
