For those interested. I finially finished converting my YS VF3 over to EP. Changing motor mounts and getting weight out.

The plane was 10.lbs with the YS-170 in it without fuel. The conversion with a Hacker A60-7S-V2 and a CC-80-HV ready to fly without motor flight packs is 7.86+/-lbs. The flight weight with True RC 15C/5000 packs (640oz per) is 10.86lbs. I have other areas yet to exploit weight from (gear, wheels, spinner, prop. FASST reciever, and lighter flight batteries). Just switching to F3A Unlimited packs at 592grams will get me down to about 10.5 lbs or so.

I would not have made weight or teetered on it, if I left in the pre-fabricated mount from Esprit Rc in it. The mount is a great mount, but making my own out of wood reduced the weight by more than half. I have posted some photo's of the completed project. More photo's to folow with the ducting, etc.
