The A-10 could be done as an electric. This would make it nearly impossible to get a one engine out situation (NEVER SAY NEVER). It would also simplify initial set up as getting two electric fans to run reliably and at same speed is a lot easier than two glow engines.

However, the costs would be very high. The fans, motors, controllers and charger would run costs similar to a pair of fans, engines and pipes, but there is still the cost of the batteries. Since batteries have a long life if you fly the plane a lot, after about 100 flights the cost of fuel would be start becoming greater than the investment in batteries.

The other down side is flight times (about 5 min max) and lower thrust. The plane weight with batteries would be reasonably close the a fueled A-10.

You could also build one of a reasonable size (up to 80") and the Cbt Models A-10 has been converted a few times to electric. There are a few small electric A-10s out there but even the Cbt one is small for may tastes.

Just thinking out loud. For glow though a single is a much better path.
