Where on the PCB are the RF signals entering/exiting?
I'm having interference issues when using a larger battery/higher power setting. Reception drops out and CF hits the ceiling. Not the case with other, smaller batteries. I don't have KiCad, so I can't really pull up the schematic.
Thanks for any pics/diagrams anyone has.
Locatino of RX/TX chip on the PCB?

It's the one marked U2 in the top component placement pdf. The blue is the chip antenna and the small components in-between is the RF filter.
Have you just exchanged to a larger battery or put more powerful motors as well? We have also experienced RF interference when putting double motors on. It seems that the increased current interfere with the radio due to voltage ripple on the supply. Switching to 2M data-rate seam to fix most of it but adding decoupling capacitance is a good idea.
