Ah....OK. Your first note didn't mention the voltages. Yes, the R6014FS receiver puts out 3.0V on channels 1 and 2 only, and 2.7V on all of the other channels. That issue has been known for quite a while. The processor Futaba used to get the high processing speed of the receiver does have a lower output voltage. Futaba made the choice to get the high speed and low latency of the system. They did not do it to obviate other types of equipment. Please note that no recent-production Futaba equipment is not affected by the R6014FS receiver's output. Also please note that Futaba is under no obligation to insure compatibility with non-Futaba equipment. Finally, there is no industry "standard" for signal voltage levels. The 3.0V came about because it happened to be the voltage level used on many of the older output chips. The more-modern chips run at lower voltages, and we'll see more of this.
You may need to discuss the voltage level with your servo maker. Some non-Futaba equipment makers have updates available for their equipment to make it compatible.
