Not soon. I strongly suggest you try the MX2. It has the same wing as an Extra, the wing position (upper location) is just a little lower on the fuse which cleans up some of the turbulence around the H-stabs, the elevators are larger for 3D, it's built a little stronger and the cowl has a venting area at the bottom so there is no need to cut a gaping hole in the bottom.

I was flying mine today with DLE-55 and a canister setup, it is an extraordinarily nice airplane. I'd have to say it (and the Giles G202 version) is the best 50cc plane we have made to date. This is why I didn't order a bunch more Extras, I felt this new one would do everything the Extra can and more.
