OK Andy....

You're going to be in the 3lb+ range in my estimation with standard radio gear (and fuel) added.

As I mentioned in my first post, strive to install the lightest suitable radio gear you can. I really think this model will be on the low end of the performance curve...bordering on marginal with the .15 installed. For a basic trainer...there's a point where being too low powered can take expert skills to avoid a unscheduled meeting with the ground!

Best bet is to give it a try and see how it pans out. Duraplanes are pretty rugged.

If it is at all possible to install a slightly larger motor...do so.
