Default Twinn Rexx returning in 2017

Over the years since the kit production stopped, I have received many dozens of emails requesting a kit and or body. So a little while back I decided to do it again.

The latest information can be found here: http://www.tech-mp.com/twinn_rexx.htm

I am looking for motor suggestions - 650 to 800 watts with KV around 1900.
Most of the motors I used to know don't seem to exist anymore...
