I think if you know how to handle a screwdriver (because this hobby I think you can

) you can replace it yourself.

Only in a quick search I did not find a replacement screen

In some charger connections a diode is placed to prevent wrong polarity. When charging too much current this diode will be blown. Most of the time this diode is close placed to the charge connector.

Hello, I have r304sb receiver, it is 4 channels and there is a channel that puts s-bus2. I have servo futaba sbus2.

My question is, does the sbus2 servo connect to its channel where it always (channel 1) or does it put on the channel that commented the one that puts sbus2 that is in blue?

What is that channel worth?

Thanks and best regards

I think both is possible. On the SBUS you can program the servo to any channel. I know on the 7PX/7XC there is a port on the transmitter you can use to connect and program the servo's, Look into the manual if the 4PX has the same

Move the button in the middle to the right, menu comes up, look for EXP. Adjust as needed.

Has anyone had any issues with the centre button / joystick thing on these? On one I have here it sticks horribly, wasn't even working when pushed down, opened it up and a bulk load of contact cleaner has helped (can kind of navigate menus now) but still sticks a lot, changing a model name would be an hour job lol

Same as mine, and I did what you did. I pray that it won't happen again. Because I have no other solution. It works very well since it happened, around 1 year
