Default Sig Kavalier

I have been running this airplane with a .40 size Super Tigre glow engine. I had a .40 O.S. Surpass on it before and that engine didn't have enough power to get it off the grass. I have difficulty slowing it down and recently had a minor mishap, breaking the motor mount. Since it's a small plane, I've decided to consider outfitting it with an electric setup. I'm also trying to get away from the cleanup required with glow engines and have converted to gas on my other planes.

Does anyone have experience with this aircraft and if so, any recommendations for a conversion to electric power? Thanks for your help.

I had one of those from 88 through 95.  Great airplane.  I would be hesitant to convert it to electric because it's a heavy airframe to start with and you'd probably have to remove the wing after each flight to swap batteries.

With that said, if you really want to convert it to electric, I'd recommend the set-up I used on my WM Rambler 45 conversion.  E-flite Power 46 and 5S 3700 to 5000 battery and an APC 13 x 6.5 E-Prop.  I also recommend a shorting plug to keep the motor curcuit open (off) until you're ready to fly.

I'd mount the motor using the included X-mount on stand-offs.  You might want to consider purchasing a new cowl.  The Power 46 should fit  fully enclosed.  Open up the bottom front to allow cooling air and add a couple of holes to the firewall and an exit hole on the bottom of the fuselage to allow air flow through the battery compartment.
