Hi Splais,
I've got two of these from Tom. I had a thread with some info on the LR-1, its probably on page 2 or 3 .

I ended up putting in a .36 heli engine in one and the other will be electric powered.

Glow powered is ready for maiden but I wanted to get the electric one finished so I can maiden them both together.

My heavily equiped glow version came out at just 49 oz with no fuel. Thats with 4-HS85MG, 1 HS81, 600 mah Nicad, 12 oz eng and muffler, Magnum 2" alum spinner, and no wheel pants.

You can go quite a bit lighter with a .25 and HS81's and a 350 mah pack. The wing is BIG.

Or, you could go for a hot .40 and do some stress testing of the wing in a pylon turn

There's also a couple of threads over at RCGroups in the high performance electric forum.

I think its a very good price for the all composite racer!
