<P>Well said. I have two Abbras one electric and the other one YS. Both electric and glow are good. In my case, the pilot is the only bad stuff. I would like to see the YS-CDI in the market soon. That will make pattern even more interesting. Also, I wish that someone makes a gasoline engine in small size with the power density we need. I saw 3-4 years ago someone using a 4 cycle gasoline engine. I wonder if they add fuel injection and supercharge in 4 cycle engine we will get good results. </P>

<TD vAlign=top>Glow is good, Electric is good!!! Those of us that choose to stick with Electric have our reasons. As stated before, don't forget, we used to fly glow.. This is a silly conversation really. Everyone has their own individual needs and likes out of their plane. <BR>And as far as I can tell, E power is having little trouble for the most part making weight. I haven't had a problem yet. Now, if when I was weighed, if I had an allowance to fly heavier than 11lbs would I? At the nats, heck yes. IMO, in the wind it is an advantage to be a little heavier. <BR><BR><BR>
