Cool!

I'm head of the structures group for our University's entry in this years AIAA design and build competition.
We have to design, build, and fly a blended wing aircraft thats capable of lifting a 1.6kg payload using an OS61 engine! Should be interesting.
Oh, I'm also in the pilots squad too.

1.6 kg should be an easy lift for the OS. Are there size limits?
Last year's SAE planes with 1200 sq.in. total planform area could manage over 11 kg. payload.

There is an intricate scoring system based on size, aspect ratios, weight, and quite a large component on the handling. We need to do two flights - one loaded and one unloaded. A third flight is then done by some aerobatics champion to evaluate the handling based on the Harper-Cooper evaluation system.
AR >= 2.0
We are meant to achieve the highest wing loading and best payload weight-to-take-off weight ratio. In other words, a super light, smallish structure.

The motor is actually a Thunder Tiger. Got that wrong.

That's a bit more intricate than the SAE grunt-'til-you-drop max weight possible competition.

A lifting aerobat shouldn't too difficult to construct.
Something along the lines of an Evans Simitar.
