My Feedback: (29)

During the Toledo show I was able to talk directly with the folks at Futaba. We expressed our concern about the low voltage signal from the R6014FS receiver. We also expressed concern about Futaba's silence regarding this issue. I received this letter from Futaba USA. This letter suggests the 14 ch. rx signal voltage is intentional to attain the speed required to process the data fast enough and clean enough for the 14 ch to function. Since this low voltage signal is required, it would suggest there will not be any new 6114 rx in the future.

Here is the letter


Futaba Product Advisory- R6014FS Receiver

Whereas many previous receivers offered a signal output of 3.0 Volts, the latest generation of IC’s has been designed to operate at lower voltages in order to increase their operational speeds. The R6014FS receiver utilizes such an IC and, as such, the nominal output voltage of the R6014FS receiver is 2.7 Volts.

While this variance in the output voltage will not affect most equipment in use today, it has been brought to our attention that some manufacturer’s products are not capable of operation with the lower voltage. That is, they will not operate below 3.0 volts. Some examples of what we have had reported thus far includes sequencers, cut-off valves, older servo designs and some recent non-Futaba digital servos.

Some battery back-up devices might have difficulties with the lower operational voltages as well, although they might not appear to initially. One such device appears to function perfectly on the ground and during a range check, yet when the operational temperature reaches 500 C (1220 F), the device actually requires 2.8 Volts in order to function properly. As such, the servos will cease to operate properly.

Many of the manufacturers are updating, or refining their products to ensure compatibility with the lower operational voltages. Should you have any questions about the operation of such peripheral items we strongly suggest that you contact the manufacturer directly.

If you have already purchased items which are not capable of operation below 3.0 Volts, we suggest that you either replace the item with an updated version or utilize a device to increase the voltage accordingly. Examples of such devices include: ElectroDynamics’ Buffer- Amplifier Interface, Duralite’s PowerBox (manufactured within the last six months), EMcotec’s DPSI products, etc.
