Here's my ETaco. Here's the setup:

AXI 280824 Outrunner
Jetti Advance 40p ESC
2 Kokam 3 cell 1500 mAh Batteries

It's got good power.. But it's not half the bird Chuck Auger came up with...... Hopefully he'll chime in here and lay out his setup.... I really like the mods he came up with for the airframe.... I'll be incorporating those changes into the ETaco kit.... He got his covered airframe down to something like 7 oz.!! He nixed the fiberglass rod and ply motor mount, use a CF tube that goes all the way to the motor. Then he nixed all of the sheeting on the wing.... Really nice setup.... Very well done.
