When \"4S series servos\" that support serial compatible are connected to the B\/S port in the new receiver KR-420XT, you can use \"REAL TIME ICS\". So, you can easily change parameters of servos from the transmitter without accessing the car directly. Setting your car with more freedom and more detail without compromise.\u003cbr\u003e\u003cbr\u003eAlso, even using the XT Telemetry mode that is 2-way communication, the High-speed response is still faster thanthe EX-RR.\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eHigh speed supported by Serial servo.\u003c\/strong\u003e\u003cbr\u003eCurrently mainstream servo control method is performed by PWM control. PWM control method uses pulse width to send position of servos output from receiver. Serial control method uses a digital signal value to send the position of the servo output. So, communication speed of the Serial control method will be significantly faster than a PWM control method, time ofthe servo’s action from your operation input is shorter. Operating feeling will be ultra high speed like operating thecar directly.\u003cbr\u003e\u003cbr\u003e\u003ccompatible servos\u003e RSx4S \/ BSx4S Series\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eUltra small receiver KR-242XT\u003c\/strong\u003e\u003cbr\u003eIncludes KR-242XT, which is even more compact than KR-418FH. The short antenna type, which is easy to handle, allows the antenna to stand directly on the receiver.\u003cbr\u003e\u003cbr\u003eBy connecting a 4S servo to the B \/ S port, you can operate the servo serially. Also, if you connect to 1 to 4CH, you can use the conventional servo. It also supports HCS by switching the port mode.\u003cbr\u003e\u003cbr\u003e*The KR-242XT is exclusively for XT Telemetry and does not support XT Advanced Mode.\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eLCD extension unit 2 with various functions\u003c\/strong\u003e\u003cbr\u003eLCD expansion unit 2 EXP-201 supports various RF modes, response modes, and various setting items added from EX-NEXT. Easy setting is possible with easy-to-understand menu structure and button operation. This product has a new ICS servo setting function. It supports not only 4S serial servos but also conventional ICS servos. You can change the servo parameters by connecting the servo directly to expansion 2 without using a PC or servo model selector. In addition, it is necessary to change the ID when using multiple 4S servos serially, but it can be easily assigned from this product.\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eContents\u003c\/strong\u003e\u003cbr\u003eMaster Unit EX-NEXT (Black SP) x1\u003cbr\u003eLCD Xpansion Unit2 EXP-201 x1\u003cbr\u003eReceiver: KR-242XT (Short antenna)  ×1\u003cbr\u003e\u003cbr\u003e\u003cbr\u003e\u003c\/compatible\u003e","brand":"KO PROPO","offers":[{"title":"Default Title","offer_id":55450567377276,"sku":"KO10790","price":189.99,"currency_code":"GBP","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0432\/8584\/0033\/files\/ko10790_1.jpg?v=1750132765","url":"https:\/\/sussex-model-centre.co.uk\/products\/master-unit-ex-next-basic-upgrade-wkr-420xt-shrt","provider":"Sussex Model Centre","version":"1.0","type":"link"}
