270CFX with DX8 GEN 2 Does not Spin Up

Hi Lubeman, I use a DX9 with throttle hold on the A switch. Button I is used for bail out.

Ok perfect that's what I have mine setup on as well(DX9) but TH for me is switch H and your A so, I recommend you setup TC on switch H

1) System setup-channel assign-channel input config Aux3=H
2) Model setup-throttle cut-position -100/switch/switch-H first position box open second box highlighted for active TC

Look at the monitor when you flip the switch away from you should show assigned throttle output, switch towards you -100 for ESC arm and softstart. I then assigned voice alerts, Armed= "gyro initialized" Disarmed= "Motor off"

Then you will set you TH % per the posts above to bailout.

Good luck!

Ok, use any other switch you feel comfortable with.

Very low input value on the throttle channel: -124 for the 270. The 360 Trio manual suggests -130. The ESC is armed when you hear the short melody after initializing.

No 0 in N is fine. Your ESC arms in any mode, because you have set you throttle hold at 0 (and not at 10, pls. refer to my previous post). However, this is the reason why the quick recovery autorotation feature of your ESC does not work.

You need two "motor off" positions. One very low position to arm the ESC & following soft start and another slightly higher position for quick autorotation recovery. Your set-up appears to miss the last one.

That's why we differentiate between throttle cut and throttle hold and program different values behind, e.g. -124 for T/C and -99 for T/H (realized by a value of flat 10 in the throttle curve menu). The ESC translates those throttle values to its two different spool-up rates (initial spool-up and head speed change).

I'll try and work through this and let you know what happens, thanks again for your time and help
