The Valiants will be close on weight when built as electric. You will have to pay attention to what you stick in the planes. Here's some of the stuff I did on mine.

Servos: 9650 for elevators, BL551 for ailerons and BL352 for Rud (replacing the 9156's I put in for test flight)
8ch Fasst Rx, SA 6V reg, small Futaba switch and 730 TP Rx batt
I used a .9 meter SA quad-wire extension back to the elevators which eliminated 2 wires going to the back (.9M works if the Rx is mounted at the back of the hatch area)
Rx, Rx Batt, Reg and controller are velcro'd to the side of fuselage with small pieces
The velcro straps for the main battery will be 1/2" instead of 1"
Du-Bro 2" Super Light foam wheels with 3mm bolts for axles (didn't have time to order the cool aluminum axles [] )
1" foam Du-Bro tailwheel on a wire tailwheel system
no ball-bearing linkages anywhere
Battery tray is some leftover pipe tunnel fiberglass board I had from some Integrals (which will be shortened now that I know the batteries go into the nose)


Things I have not done to lighten it:

Tru-Turn 3.25" Spinner
APC 21x14
Stock gear and wing tube
Du-Bro steel turnbuckles for pushrods

Total weight of this one is about 10.78lbs*
*This is NOT the center hinged wing model. That adds a few ounces over the skin hinged wings I have on my first model which I predict to be right at 11lbs
