Ha! Good, luck! The Blackhawk has computer controlled hydraulics and gobs of power - you may get a flat hover out of the Axe but I suspect angling the tail will lead to control problems. Speaking of which:

alienteabagger! Yes we are on the same page. I think I made a big discovery on the setup - its more important to get that swashplate level than to have the servo arms at exactly 90 degrees.

You can't have both a level swashplate AND perfectly level servo arms. Not possible! On those linkages, you can only make full turns, not half turns, so it will always be off if the servo arms are perfect. Level swashplate has priority! That is my big lesson learned today!

My other big discovery is to adjust zero degrees pitch when the radio says its at 50%, regardless of the stick position, which in my case is just a little above mid-stick. I had mistakenly adjusted zero pitch when at exactly mid-stick, so I was off a tad there.

I still don't understand why JumpJet101 has a different swash mix. We are both using HS-55 and its the same heli, same wiring, same orientation, right?

Now then, I deleted the mixes. Ok.

I spent a lot of time staring at the end points of the servo travel. Everything seems perfect now. The swashplate stays level all the way up and all the way down. The maximum positive and negative collective pitch angles are acheived.

More testing is in order. I smell victory right around the corner now. No - not that wall!!! Bank! Flare!!! ARRGH!!!! BLAM!!! OUCH!!!

Reminder: Hover should be right around 55% - 65% up stick, both in Normal Flight Mode and Stunt Mode 1. The idea is to lift off, hover, then get some altitude in Normal Mode, and hover again. When you flick the switch to Stunt Mode 1, the Axe should not plummet to a sudden death nor pop up in an uncontrolled climb. She should just immediately increase headspeed and decrease collective but still maintain stable hover.
