I just received my U can DO last night. Total components weight after unpacking was 4.71 lb.

This means that 7 - 7.5 lb is achievable, but not with the recommended equipment. 7.5 - 8 lb is what you'd get if you used standard size servos and a 600 mAh NiCD.

I've seen Sensai's plane fly with 8411's (heavy), an OS 91FX (heavy), and a 1500 mAH pack (heavy -- or was it a powerflight pack). He claims 7.8 lb. I'm curious whether his airframe components were lighter than mine...

I've found the following issues/problems so far :

1) The outboard ends of the aileron LE's were oversanded, causing a 3/16" assembly gap outboard of the last hinge.

2) Fuelproofing -- the firewall is fuelproofed on the outside, but there's no fuelproofing in the fuel compartment in the fuse.

3) The fuse former just behind the canopy was pulled away from the fuse side with glue in the slot. It looked like the fuse wasn't kept in the jig long enough for the glue to cure.



Overall comments :

o This ARF requires less user assembly than any other I've seen. You don't even have to join the wing halves!

o This thing is built strong. The average person won't have any problems with it.

o The monocote was applied over itself -- e.g. the wing bottom is entirely red with white squares monocoted on top. This will lead to bubbles eventually and makes the plane several ounces heaver than it otherwise would have been.

o This plane could be constructed at least a pound lighter than it is now. I'd love to pay extra for one of these that came in at 6.5 lb with a saito 100 and mini servos!
