An update...

The LHS was kind enough to exchange the AXI 4130/16 for a 4120/18. Put on an APC 15x10E and it now pulls a respectable 1045 Watts. The AUW is 7.8 lbs, and we are measuring thrust at approximatly 7.2 lbs. Still using the 18.5V 5S2P 8000 mAH. This thing it wicked scary to play with on the bench. Nice and quiet, but that mean hum warns you of the danger.

The 4120 is about 3/8" shorter, so we had to put a bushing on the shaft to clear the front of the fuse sidewalls. Still, it worked out nicely. Lighter than planned. Moved the Rx over on the right side wall over the servos, mounted with velcro. The battery is sitting on the Rx tray now, and we added a triple ice-cream stick beam forward on the lonerons in the lower front fuse section. Put down a foam pad, and strapped the battery with a velcro belt. Stays put well enough. Balance is on the forward marker with the center of the battery dead under the leading edge of the wing.

It's ready to fly. Hope to get some time this weekend to take it for a spin.
