Ihave an untouched SL1A kits in the loft I have often thought about building for electric. Biggest problem I can see is the undercarriage. The plane is designed for retracts not fixed gear and I would need to substancially increase the length of the undercarriage legs to account for the big diameter props you need for an electric motor.
It ticks all the rest of the boxes. Big Fuse. Plug in Wings and tail. Generous nose area for cooling. Definitely has potential.

it was an expensive kit and I am going to need to do something with it.
