Programmable radios are great with channel mixing and servo recoil. The issue is they are so programmable and it is possible to get the sticks and functions completely twisted up. When you start having issues, it makes trouble shooting hard. Now the DBC3 Benedini is simple simple,, but because of programmable radios I have had to do some trouble shooting.

If someone is having a problem, the first thing I tell them to do is get a standard radio that you know works and use that.
