The design aim of SRX series servo is to reduce the weight and size as much as possible, and make it suitable for the micro indoor electric aircraft. Do not take it for granted that micro aircrafts don't require a high capacity receiver. also we keep shortly Ant length, Only on few occasions that the reducing capacity of the receiver seems not have terrible impact. Once there are more transmitters around the ground, indoor RF is much worse than that of outdoor. Cordless phone usually have a 300m (1000') range in the open field, while indoors, when it will have some noise somewhere in the same room with the base unit. The engineers of Scanner noticed it. So, aside form using the latest SMT technology to manufacture SRX of 4g only, they also make it have all the capacities of full-range receiver. Therefore, SRX can be used by all the R/C aircrafts, including micro indoor electronic plane and full-size glow plane and helicopter as well. Most of feature is that SRX receiver can be automatic select Hi-Bend or Lo-Bend whatever you insert which bend of crystals. you can simply to match Futaba system or JR system without switch.
See the SRX User Guide for more details. If you are interested in R/C technology, please look over the technologies that we adopt.
Also, you can also buy our a pare of crystal for commutation equipment, it's depend on your transmitter system and has different Li-Bend or Lo-Bend, in that case we would like mention you double check you radio system and receivers socket of crystals.

1.Check that your transmitter and receiver are operating on the same frequency.
2.Check the polarity and integrity of connections when plugging servo connectors into your receiver.
3.Always carry out a range check prior to flight.
4.In order to safely and properly operate your R/C equipment, please read thoroughly All manufacturers manuals and instructions.
5.Always turn the transmitter on first, then the receiver. When you turn the system off, always turn the receiver off first then transmitter.
