The AeroCat, a 70+mph flat foamie!
Got my AeroCat flying and LOVE it!

Wingspan–32"
Length–31"
AUW–7-15 oz.
Speed Range–45-75 MPH

I decided to go light and fast. I'm using a LittleScreamer Beast motor, Cool Running A-12 ESC, APC 6 x 5.5 prop, TP900mAh 11.1v battery, JR610 rx, and the new E-Flite S75 servos. My AUW with battery is 8.7 oz's. It is FAST, but floats in to land. I added flat c/f at the back of the wing where the ailerons attach, to brace up the wing a little more, and it really helps keep the wing tips from flexing. I also added wind fairings to the motor mount, rx, all servos, and a partial wind fairing for the battery. Even though it's foam, it doesn't hurt to streamline everything possible.

I ordered the kit from Model Aero at http://www.modelaero.com (http:///).
The LittleScreamer Beast motor is unbelievably powerful for it's size and weighs only 23 grams! It is a specially ordered motor from LittleScreamer. If you're interested, call Scott at (425) 971-9121, between the hours of 7am to 6pm PST (west coast time). He's a really good guy! I recently discovered Cool Running ESC's while building and flying the Miss Hangar One hydoplane flyer and I really, really think they are the best ESC's out there for the money. So much smoother than any ESC I've ever used. Check'em out at coolesc.com (http:///). And finally, I'm using E-Flite's new S75 servos. I'm flying them in three different aircraft currently,and believe them to be the best sub-micro servos out there and best of all they are only $14 each! Plenty of torque(17.2 oz/in), fast, light (7.5 grams) and include extra long servo arms! I use JR610 rx's in all my electric aircraft and love them. I've had NO problems with them at all.
This aircraft flies like it's on rails doesn't it?!!!
Several guys at the field today just had their jaws dropped watching this bird fly! One guy said to me "I had no idea that flat foam could fly SO fast!" Another guy said "Holy http://www.rcgroups.com/forums/images/smilies/smiley35.gif , that's fast!!!"
I LOVE it!!!

p.s.
You'll notice in some pictures the wind fairings are not in place, I added these after a few flights.
