Many customers are installing electric motors in my kits, any and all of them. Electric motors have been around since the 90's, I flew my black e-powered Big Bird in the 1998 KRC event in Pennsylvania. Another contestant was flying a Sky Bench kit too, my awesome performing 2M Osprey. You will be hearing more about my Ospreys. It is relatively easy to install the e-power package. Check the charts at the top of my "Electric Sailplane" page for help on deciding what size motor to use based on watts. The first two digits of the Ammo motors is the diameter of the motor. Also, use the "Gear Drive" link to select a gear box. More NEWS to come ... Check back soon!
Building Tip: secure the wire push rods with small pieces of tubing cut from the tubing provided in my kits to the fuse sides between the fuse formers to prevent bowing. I use a small dab of clear Silicone glue on the tubes. Do this before you add the top/bottom. I bought a built OLY lll and had to open up the bottom of the fuse to anchor the push wires. I could hear the rudder push wire hitting the side of the fuse by moving the rudder by hand while the servo/Rx was turned on.
Please Read the above articles
Notice: I'm changing some of the kits over to balsa instead of light ply on the front fuse sides. This will speed up builder construction time and save 3-4 oz, just what we are looking for when considering installing an electric motor.
