Then go to 16, 16-1/2-degrees. When you're comfortable with the handling for take off and landings, and you've got the runway for it, 17-degrees is good for cruising, but not a short runway.. This all presumes a bit on wing loading, but 15 is a good place to start.

I have square tips, 72". I think static at 16 is 4600 or so which is way below what would be recommended for static but as long as you have a long runway and set an abort point just in case then I wouldn't worry about a 4600 rpm (I think people would usually shoot for a couple hundred rpm below redline to make sure max power is available). How much does your Avid weigh? Speed wing or standard? I'm sure you'll be happy with it, I'm still loving my Pelican with the Stratus every flight. gary Andy Fultz wrote: > > > Well,, my STRATUS EA-81 engine is now on the airframe and running.

Don't know for sure what the completed weight will be. I do know it won't be one of the lightest though.

I put the prop on today and set it at 15 degrees for starts. I did use a level to make sure each blade was level horizontally and then set the pitch on each blade. I rechecked as I tightened and only had one move a little. I readjusted it. Checked the tracking and one blade is out about 1/8" and one is out about 1/4" inch. I would like to have seen them a little closer on the tracking. I didn't have it tied down so I didn't run it over about 2200 RPM. I feel a littel vibration but not as bad as some I've been in. Then I spent most of the afternoon tying up the rats nest behind the panel. I just might actually fly this thing before the end of the summer if I'm lucky. Thanks again guys.
