Status: offline 		The UIUC "Chambana Belle" had her maiden flight today, and managed to leave the ground and return to it intact. Modifications are needed, however, as without the expert hands of Mike Cross on the sticks it probably wouldn't have managed the return.

The plane needs a bigger fin, and the extension is going in the bag tomorrow. After wobbling around the sky for a bit, it spun down and was recovered and landed by Mr. Cross (THANK YOU!!!!)

For those that weren't following the side discussion in the SAE Aerodesign thread, the Belle is a moldless composite aircraft. It is powered by a geared Astro 60 turning an 18X18 on 40 CP1300s. It has a wingspan of 8 feet and an overall length just shy of 4.

It is UIUC's entry into this year's AIAA Cessna/ONR Design/Build/Fly Competition: http://www.aae.uiuc.edu/aiaadbf/

Pictures will follow - must cut them down to size.

Almost short enough to be a flying wing. But WAY too short! You better lock Mike onto that project, there's no one better!

Status: offline 		Actually, I've been looking for a 6 inch wide r/c Humvee... my brother suggested a LAPES inflight release.. which is possible with the open bottom and rear.
Pop the thing out the back during a low pass, and drive it off the pallete.

Yeah, she's a beast, but it only takes about ten seconds to assemble her out of the box. Mike is definitely the best there is, and has generously volunteered his time as pilot for the team in the past. This year, however, I'll be taking over as pilot once the bugs are worked out.

.
The four foot inside box length determines that, if you don't want a two-piece fuselage.
The teams are scored on assembly time as part of the grade.
Lots of parts takes longer.
.
It is a tad or two shorter than I'd care for.
And maybe a bit of dihedral to aid lateral stability, since it spun in. Lots of washour also.. or skip a seperate horizontal completely, make it a wing and pod.
And put a trike gear on it.
That's what neat about these competitions, there's any number of ways to meet the specs.
But the plane MUST fly also.
The easier that is, the more likelihood of a good placement in the results.
