Bavarian Demon 3x on Large Vario Huey
I've installed a Bavarian Demon 3x in my large turbine powered Vario Huey. My first maiden attempt ended with the helicopter tilting over and the blades striking the ground. I've never set up or flown a Demon in any other of my helicopters so I wanted to reach out to some people that have a lot more experience with the stabilization system and walk through my setup to make sure it is correct before I try to re-maiden the helicopter.

The most likely cause of a rollover on a maiden flight is the mounting orientation being set wrong. This should have been caught with a preflight control check. Please contact me if you have any questions,

Also check the serial number is high enough to be used on a turbine. They also recommend using a suppression hood if you mount it inside a fuselage. If the control checks are ok, these are things to look at. I had some weird things going on in my turbine until I found out it was a little too old and not designed to work on a turbine without the hood.

From the manual: IMPORTANT NOTE IN CASE OF USE WITH TURBINE HELICOPTERS!
Only for systems with serial number < 70-x-x (Delivery prior to December 2013):
If running a turbine, it is mandatory to apply the protectvie hood, available as accessory, protecting the unit from the infl uence of ultrasonic sound. Newer
system are not affected, as their sensors are resistant to ultra-acoustic noise.
