Dave,
Most any Classic or Vintage pattern plane can be adapted to electric power. There are several pattern pilots that compete in the local contest with electric power.
The biggest hurdle is getting to the batteries without having to take the wing off. As most pattern planes don't have hatches for battery access.
However, the Super Kaos can be built with a hatch where the fuel tank would have normally been located. Since you won't need a fuel tank, this makes a perfect place for the battery.
On June 28th, we will be having the 2nd Annual Golden Triangle Aerobatic Convention and you can get a first hand look at electric pattern planes. We are located in Grand Prairie, TX You can also compete with the rest of the guys. You don't have to be an Expert pilot to compete.
