Thanks for the info. I'll try both types of props on the little bugger. I tried it again tonight after moving the COG back a little more. After the initial climb, I still have to keep it at full throttle to maintain altitude. Not really looking for speed, just would like to hold the altitude for a few minutes. My next idea is to reduce the recommended down thrust to see if that improves the situation, if the new props don't change anything. I've read both positive and negative posts about this little airplane and I'm thinking that there must be a key step that I'm missing. I'll post here again after I try the newer props.

Thanks again for the info!!
