[NSRCA-discussion] Small Models ... goodforthefutureofthePattern Event?

[Rcmaster199 at aol.com]

A twin set-up has much to offer and is worth investment (invention and money) 
to get the technical side perfected. However, electric twins are not as 
straight forward as one might think at first glance. Sure, the powerplants will 
allow more latitude than wet power, and counter rotation is a cinch in a twin 
that has two nacelles. The key ingredient is too much weight for the kind of 
"pattern performance" Dave is alluding to.

Contra rotating twin props on a common axis is more of a technical challenge 
and weight is still a key issue.

Once we figure out how to curb the weight issue, this will become reality. 
Put on your thinking caps and have at it. If one can build/buy a complete 
airframe that weighs in at around 3 1/2 lbs, then it's doable with minimal/no 
invention required.

You won't see "pattern performance" on 1800 watts and 11 lbs (163 watts /
lb).  The "best" electrics are currently pushing 250 watts / lb (and I have
flown 300 watt / lb setups) and the "best" glow setups are 275 + watts / lb.

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

another local Pattern flyer.
