Sure wish you'd bring that thing down and fly it around my neighborhood. Bob

You always have a good one Bob

You sure are working that one hard Elson, That is a lot of fuel in 25 min. Keep us posted on it's longevity.

Sounds cool! What are you trying to do by catching the bugs? Seems like your killing quite a few of the same bugs your trying to catch with the prop. I know when I land my 32x12 and the cowl has little blood spots all over the plane.
