Servo Reversers and Spektrum

     I have recently been contacted by several customers regarding the compatibility of our Servo Reversers with Spektrum receivers. After talking with these customers individually, I decided that it might be good to address the issue here, to answer some who may be wondering, but who have not yet reached out to us.

    It appears that some modelers have experienced problems when using certain reversers (not ours) with Spektrum radios, and I understand that a spokesperson from Horizon has suggested in various RC forums that reversers of any kind should not be used with Spektrum receivers, as they create some type of interference that can disrupt the receiver's operations, even though they are operating on the 2.4GHz band, which is supposed to be much less susceptible to EMI or RFI interference.

     I'm not sure which reversers have actually been causing problems, but I do know that we have been providing servo reversers for several years now to users of every brand and type of radio system out there, and we have received absolutely ZERO reports of problems or incompatibility with any brand of radio, including Spektrum.

     Electronically, there are several ways that the PWM signal used to control a servo can be produced, and it is very possible that some reversers being made overseas use a design that is faulty, and that indeed creates interference.  Our reversers, as well as most of the other circuits we make, like Navigation Lights, Servo Speed Reducers, Servo Testers, etc., all use a microcontroller to create the PWN signal, and they do not produce any interference of any kind.  There are thousands of our devices in use in models around the world, including reversers, and we've never received a complaint about a single one being non-compatible.

     Our reversers "read" the signal from the receiver, do some math on it to switch it from one side of the channel's center to the other, and then send it back out to the servo, all done in a few microseconds!  They can be safely used in Spektrum systems.  -David

     The 2022 swap meet season is about to begin, our first event will be this weekend in Perry, Ga at the Southeastern Model Show.  As a result, any orders placed between March 1st and 6th will not be filled until we return on March 7th. We look forward to seeing all of our old customers, and making new ones, too!
