A personal friend of mine in the U.S. has ordered one with a Hirth 23 engine, there is a 12 month wait. I checked with RAAus and they on the approved kit list here and can be done under 19 rego, not sure on the electric model.
I got all the pricing on one and naturally more expensive than the 2 stroke powered ones. Can choose Hirth, Polini or MZ engines, naturally no more Rotax.
They generally fly in the U.S. under the FAR Part 103 regime, no rego, no licence needed. Sure wish we had that category in Australia. A low budget entry point for Foundation Aviation. Australia is too dumb for something like that 🙂
