<DIV>Lol, I got you my brother.. Not trying to go there.. haha</DIV>
<DIV>I would assume that the 110 sized plane won't be light as you or I didn't
build it Mike.. lol.. You could probably build a 2M BM and put a foamy motor
on it as light as you build.. You'll probably like next months cover pic on
the Kfactor. Well, next, uh, well, let's see, the April Kfactor. </DIV>

with virtually<BR>> no aerobatic capability = 50 to 75 watts per pound.
For models with<BR>> some aerobatic capability = 100 to 125 watts per
pound. For models<BR>> with aggressive aerobatic capability = 175 to 200
watts per pound.<BR>> HOWEVER, these "rules of thumb" are for models
weighing less than<BR>> about 5 pounds. There is a scaling factor which
most be applied for<BR>> heavier models. For example, an 11 pound
airplane would appear to<BR>> require no more than 2200 watts to be
aggressively aerobatic, but the<BR>> actual wattage requirement seems to
be about 2400 to 2500 watts.<BR>><BR>> One of these days I will sit
