I am thinking of building a SPAD, but my mind is not totally commited to this. What I am looking to do is to build an airplane than can stay aloft for at least 45 minutes. I've got a little .25 OS motor to use with this setup. I don't really care if it can do aerobatics or not. I'd like to be able to go out to the field on those somewhat windy days and take her up and fly with the nose in the wind like a kite for a long time without having to land. It would be mainly for this purpose, although I could fly it on the less windy days as well.

Is there a plane that comes to mind that can do this?

I am thinking of going with SPAD, because they are light and durable. I am trying to do this for CHEAP. I've got other balsa planes that are taking all my money. Its also kind of a game unto itself to try to do this gig for as little (both time and money) as possible. Here's the plane I am thinking of: [link=http://www.spadtothebone.com/freeplans.htm]Buhor 25[/link]. (Its under the "Trainer" option)

I'd put a 12 oz tank on it instead of the stock 8oz. With a little .25 motor at half throttle or so, I think it could stay up for a long while.

I've been talking to the guys in the SPAD forum, but decided to post here since I am not dead set on SPAD. Its the end more than the means.

Thanks.
