Default 87 inch wingspan Bird Dog, converting it to electric

I purchased an 87 inch wingspan Bird Dog at a swap meet and have decided to convert it to electric power. I wish I had gotten more information from the seller, he is the one that built the plane and did the amazing detail work. I remember seeing this plane 2 years ago and trying to buy it from him then, but we couldnt make a deal. Looks like the people who predicted the end of the wordl yesterday were wrong. They had the date right, but it was me finally getting this plane, not the end of the world yesterday. They were just a bit confused. First, I will tell you what I know about this plane. It wasbuilt with droppable pods, which came with the buy. I see the lanyards that extend from the wing into the fuselage, but havent seen the release initiator. I am an ex-aircraft weapons release tech, so thats important to me. The way the cowl was built with the two scale engine access panels will aloow me to remake the gas engine mount to be narrower and mount the electric motor. I can then have room for my two huge batteries to be installed thru the doors on each side of the motor mount. There are plenty of scale openings in the front of the cowl to have ample cooling for the speed control and motor. I had a motor for sale here on RCU, guess I better cancel that ad. I should be abl;e to use two 5000 mA batteries in parallel to power the model. This is not a loud screaming by plane as are some fighters and such. It will not need the sound, but I am sure that big prop will make a great sound as it goes by. I saw a giant mustang converted to electric, and in my opinion, my eyes and ears were in conflict as the bibg mustang came boring in silently. I hope this will not turn out like that. Here are the pictures as I bought the plane, I had a pilot figure and a tailwheel for the plane. Next I will do the servos, then the motor mount and the rest. I bought a big Beechcraft Bonanza and had planned converting it to electric, but after thinking about it, I think this would be a much more fun airplane so I guess I will sell the big Top Flite Bonanza to get this one going.

Its a Valincourt design. I was lucky to be in the right place at the right time, then again I kept after it, it was 2 years from the first time I tried to buy it. I remembered I got the plans with it. I got the motor mounted, I cut a leftover piece of square aluminum tubing from my carport project and cut it and mounted some angle aluminum to attach it to the engine mount/firewall. The ESC is mounted below the motor and will have great airflow across it for cooling and there already is ample exhaust air openings. I have a 20 inch prop on it for now, I will see how that works. I only have one of the batteries, the other is somewhere between China and Florida. I will put the servos in the wings tomorrow and I can at least set everything up with the one battery.
