Thanks Guys,

Specs are:

First Version:3 channel Throttle, Elevator, Rudder, 2 CS10 Servos, 8x270 mAh nimh (They were the same size as the now 300 mAh nimh.), HY50D Motor 5:1 with a 7.25x4 Modella CO2 prop Hitec 5 speed control, and Carbon fiber Push rods.

Now: Same Everything Except, 8x270 mAh nimh (the new ones, same size as 110 mAh nicad's.)They hold there voltage better. and the GWS 5.9:1 Motor with an 8x6 GWS Prop.

Flight Charateristics are great, and alot of fun to ROG.

Nice DVII! You did a great job at keeping the weight low. I'm almost finished with a Guillow's Thomas Morse S4C Scout which is the same size as the DVII and the weight will probably be almost 8oz. I couldn't resist adding ailerons so that added some weight.

Is 6.5oz what it weighs now with the present GWS motor, prop, and, newer 270 (110Nicad sized) cells? I haven't seen these yet. Do you know if they are lighter than the present 300mAH 2/3AAA NiMH cells?

Did you use the kit wheels? If so, are they vacuum formed like the ones in my Herr Pitts Special? I made homemade wheels for my Tommy which came out lighter than the Guillow's kit wheels but they still were a bit heavy at about 4g each.

Any wood replacement or strengthening done to beef it up for e-power?

Thanks, Its was a fun Project!

Yes, 6.5oz is the AUW now.
As far as the batteries, they are about the same weight. They didn't have the 300s when I installed the 270s.
I did use the kit wheels which are laminated balsa. I do have a problem with them coming apart so I have to find replacement wheels.

I really didn't see a need to beef up the main structure other then installing the RC equipment. Although, I did change the landing gear, instead of the hard wood just glued to the fuse sides. I cut the hardwood struts per plan, but then glued Carbon fiber rod(.070) 2/3 the length of the inside part of the struts leaving 1/4 inch overhang at the top(to go into the fuse). Then capped each side with 1/16 sq. Balsa and shaped. On the inside of the fuse for hard points, I just glued 1/4sq.x3/8 long balsa then drilled to except the struts. Also, to save weight I used a carbon fiber axle instead of the piano wire. That alone cut half the weight of the landing gear assembly!
I hope that this makes sense.
Good luck with your S4C Scout, I would really like to see pic's , and hear how it fly's.
