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... Joe |

Acro? 3d?
Has anyone tried setting a twinn rexx up negative pitch for any reason?
Has anyone tried any acro or even 3d? Inverted hover, that sort of thing? |

I only run about -2 degrees negative pitch.
If you try to fly upside-down, please be sure to take video so we can all see what happens.
