I've designed a solution to extended the runtime of my TURNIGY 9X and FLYSKY 9X radio transmitter by creating bigger battery bay to accomodate larger battery and at the same time able to share its power supply to external devices such as FPV video goggle, external transmitter or radio booster. The 9X battery lid now have extended larger battery cavity and a slot for female XT60 plug for external power output. Now i can stay longer outdoor in the field enjoy some flying and FPV without constantly swapping TX batteries. More details can be found at 3D printing page section - Click Here.
