Hey All

I've been working on this plane for awhile, I too was kinda bummed about no wing template BUT if you (are as anal as I) the measurement way works well too.

Because of the size/weight of this plane I replaced a lot of the hardware ( it only added a few bucks to an already good deal) and I also converted this to electric.

This plane and the power system evolved in the past few months, but I now have what I believe is a good power set up.

With this ESC http://www.castlecreations.com/products/phoenix_hv-85.html

A 12S1P pack of these batteries http://www.a123systems.com/html/home.html

Here is the bench mark video of this set up http://www.rcuvideos.com/view_video.php?viewkey=160a19586f6e26eaefac

I should have 12-13 lbs of thrust, 76 Mph pitch speed and a AUW of 9 lb 14 oz

The maiden is tomorrow, so if there is an interest I can post that video here too.

In the mean time here are some of the videos of the evolution

The maiden

Some bugs need to be worked out. this unimpressive flight is due to my lack of skill and how fast these A123s dump.

More to follow
