I fly with an Airtronics Stylus multi mod radio. I use the heli mode on my 110/117. Using this mode does not create any problems. (stay away from any throttle hold switches or settings) (If you get adventures you can use the throttle hold as a kill switch (with the correct setup)

Since you do not have a collective servo (unless you are using channel 5), collective pitch curves do nothing. Collective pitch curves adjusts the collective pitch to the throttle stick position it does not adjust the throttle. You can use revolution mixing and it does help (as long as you are not use a hh gyro. I do not know about your specific radio but on mine I also have some additional control over the throttle with a variable pot that is used for fine-tuning throttle setting to hover.

There are of course many of the heli mode settings that do not apply to the LMH (since it is fixed pitch). But, some do and can be useful.
