Help! Spektrum DXS elevon mixing + motor help

For the FT mighty mini arrow that I was building, I needed elevon mixing. The manual for the DXS says that if your model pid is starting with SHTK then you have to update. Mine starts with SHTA. Does it also need to be updated, because when I perform the trim positioning when powering on the dxs that is used to acess preset program options, it does not do anything. Also, I have an 1806 motor as in power pack A. I have a 30 amp esc, so that can also handle a motor from power pack B. However, on amazon I can only find an 2212 935 kv as opposed to the power pack B 2212 1050 kv. Is the difference big enough for concern; will I be able to fly power pack B planes with a 935 kv? I am assuming a 30 Amp is enough for this motor too since the power pack b has a 25 Amp esc. Thank you!

So here is where the customer service rep comes out in me. The DXS needs to be programmed for elevon mixing using the Spektrum software. You must create a system mix that combines the two control surfaces. The other way to do it is to download a model like the Optera to the radio and then adjust the controls to how you need them.
Here is the link to the Optera file Optera Model File
This link is the google drive of every model you can download.

Now. I'll be honest with you. The DXS is the radio that makes me cringe when the customer tells me they are using it. Most of the time, it's because they are trying to use it for multiple models. Using a laptop and switching models every time you switch aircraft would be best.
The second problem I run into is non "techy" folks trying to use it. They don't understand firmware updates and how to switch models. The DXS works excellent when it's kept with the model it ships with, but after that, it becomes more trouble than it's worth. I know it's about $150 more, but the DX6e is an excellent starter radio that allows for multiple model memory and programming by computer or on the radio itself. If you look at the manual for the DX6e on page 31, it shows you can choose the model that already has the flying wing/delta mixing done for you. All you have to do is plug your servos into the right channel on the receiver.

As for your battery question, you need to buy or make a series connector. I have included a picture of one AMain sells as an example. The single plug is + and - however, the - off the one plug goes into the + of the other, and then the negative goes down to the main plug. Feel free to PM me if you have more questions.
