Another great flight on the zero today!

I didn't want to take the cowl off to measure but was able to stick a ruler in and from the front of the stock box to the front of the drive washer was about 4 1/4". With the cowl in place there is a hair less than 1" between the back of the spinner and the front of the cowl. Originally when building I though that was too much but in reality it looks perfect and allows some air to get around the spinner and cool the totally enclosed engine (just the rockers and top of the head pop out of the cowl). I tossed the red spinner and went with a Dubro 2 1/2 black spinner. Much prettier. I'll post some pics. I had to make my gear. Original was too soft I bent some 3/16 and welded in a support brace. They have worked flawlessly.
