## Questions & Answers

**Q: What do i have to use with it to be able to connect my servos with jr plugs??**
A: You can not connect servos directly to this receiver.  You need to use it with a flight controller.

**Q: How do i hook this up to matek f411-wing?  i don't see anything labeled tx uart**
A: Don't look for pads specifically labeled "TX Uart". Many flight controllers will have multiple UARTs available and each UART consists of two pads... a TX pad and an RX pad. Flight controllers will typically label the pads associated with UART1 as TX1 and RX1. The pads associated with UART2 will be labeled as TX2 and RX2. If you are trying to connect this to UART1, you will need to solder the receiver's signal wire to a TX1 pad.
However, your flight controller's firmware will also need to support the SRXL2 protocol.

**Q: Is tbe signal ppm or subs when hooking to fc??**
A: Neither. It is srxl2 protocol developed by spektrum and supported in newer versions of betaflight.

**Q: I have a thrust riot. Recommend is 1024 or 2048 receiver. Cant find. What is recommended to replace 1024 or 2048?**
A: Thats spektrum receiver is a 2048 receiver...buy that and setup in betaflight. They work great....i have them in 2 quads.
