Hi Jim,
I hope your doing well, I have been flying the mezon and mezon pro's in my planes and have had very good luck with them. My braking setup is as follows:
Manual braking
Start power 40%
End Power 58%
Brake speed .1
Brake dead time 0.0
I do things a little different on my setup. I make sure my idle is all the way down for trim. Plug in and arm the system, then i run my trim up to where the prop starts spinning, on my futaba setup this is -33 for trim. I then use my idle down feature to get the braking to work. The brake stays on until the throttle is moved back up to spin the motor. I've played with different settings and this is what I found has worked the best for myself.
