6EXHP for 400-size coaxal rotor heli. help

[castaway93]

Please help.
I have a 6EXHP and am trying to program it for a larger coaxal, cp heli that I'm building. The heli uses 2 brushless motors, 1 for each rotor. The rudder control on ch4 is the 2nd motor. I couldn't get it to put out the same rpm on both motors
Someone at another forum gave me instructions but based on a JR radio with different jargons and I'm still confused. I'm new on a cp heli configurations
Any help would greatly be appreciated

Not sure if this is going to work. The 6EXH supports only two swash types. Ch 4, rudder, is direct from the stick, no mixing except revo.

There is coax heli forum on rcgroups that might be of more help.
