Chuck,
I agree that overpowering can be counterproductive. But what I was talking about is models that struggle to stay airborne because the thrust-weight-ratio is not enough; add in ANY wind, and these lead sleds are basically unflyable. And all for 5-7 minutes... But the glitzy ads show them zooming and soaring.
And I fail to see the distinction between the manufacturer of a cheap, cheesy POS and the conglomerate that markets/sells same. But you're right; we're straying too far off topic with that.
Store your rubber bands in a closed container (a clean butter/margarine tub works great) of corn starch. The corn starch absorbs the oil and keeps the bands usable for a surprising amount of time. A bit of a mess, though; be sure to stand upwind when taking them out of the container...<BG>
There was a thread on this a while back. The consensus was that #64 rubber bands can be had so cheaply, there is no sense in trying to re-use them. Agreed; but if you have a wide-chord wing like the Sig LT-40, that needs a bigger (#67) rubber band, THOSE puppies are neither cheap nor easy to find.
