Hi,
For a paddle you should use the 6CH heli template and setup 120 degree CCPM mixing.
You really need to individually adjust the cyclic and collective numbers in CCPM according to your mechnical requirements and pitch gauge meassuring (max pitch, no bindings).
You also need to individually set servo travel min/max on all three cyclic channels to level the swashplate when on min/max collective pitch.
A ready model ini simply makes no sense IMHO for a flybar heli.
There are multiple heli / flybar / CCPM mixing threads on this forum (e.g switching CYclic1/Cyclic2 mixing channels).
Please try to learn to setup a heli correctly within DeviationTX step by step.
For a first start you can try the simple heli mixer GUI which is like Spektrum DX8 airware and has 0815 menus.
You can later convert the heli model to the advanced mixer GUI for more fine tuning / tweaking (e.g gyro gain on knob).
Reading thru Spektrum DX8 Horizon / Blade documentation helps a little bit too to get a basic understanding.
Have you already checked DeviationTX PDF manual and online html manual?
