Proper Placement and Utilization of the G3 receiver
Futaba is once again leading the way in technological advancements with the incredible G3 receivers. Never before has the ultra-fast, ultra-smooth precision of 2048 resolution been available to modelers. Not only does the R5014 DPS receiver offer twice the resolution of any receiver available, it also offers the ultimate performance in terms of the signal to noise ratio. Due to its performance, the R5014 DPS is becoming the receiver of choice for discerning modelers everywhere.
Models are also advancing at an astonishing pace and today's technology is finding its way into their design as well. From a fuselage made from carbon fiber to on-board GPS units and beyond…models are becoming increasingly complex. This complexity also increases the variables that may affect your experiences at the field.
In order to take complete advantage of the incredible resolution and sensitivity of this receiver, the modeler must ensure that the receiver is capable of performing to its full qualifications. The enhanced sensitivity may mean that this receiver also is impacted by unwanted RF noise that might otherwise not impact another receiver. Thus the modeler must make every attempt to reduce and/or eliminate any and all sources of potential noise. The information below will allow you to do so.
Proper Placement and Utilization of the receiver:
1) Place the receiver in a location which isolates it from other electrical components as well
as from conductive materials such as carbon fiber, metals, etc.
2) We suggest using NiCds or NiMHs for the receiver battery pack. Additionally, we suggest
avoiding the use of pulsed BEC systems to power the receiver. These items usually generate a
significant amount of RF and do not supply a constant voltage necessary for peak receiver performance.
3) Routing the receiver antenna-
a. Make sure that the antenna exits the canopy/fuselage immediately. Ensuring that it exits
the canopy/fuselage close to where the antenna exits the receiver case is very important.
b. Avoid routing the antenna in parallel, or in close proximity, to conductive materials.
If possible, route the antenna in an 'L-shape'. This will reduce any difficulties that may
be related to the attitude of the aircraft.
c. Make sure that the antenna is as far away from the items below as possible:
i. Engine items such as spark/glow plugs, ignition units and onboard glow starters
ii. Speed controller and electric motor wiring
4) Use of Filters-
a. It is strongly suggested that you utilize Futaba filters (FUTM4149 or FUTM4180) on all servos.
b. When using the receiver in any electric-powered models, we suggest utilizing a Futaba
filter (FUTM4149 or FUTM4180) between the electronic speed controller (ESC) and the receiver.
Even though the ESC for higher cell-count batteries might not feature a BEC for the receiver,
they include a BEC for the speed control itself.
5) Avoid the build-up of static electricity:
a. Helictopters-
i. Ground the tail boom to the frame using a grounding or anti-static strap. These are
available at most electronic stores. Simply attach one end to the tail boom and the other
to some point on the main frame.
ii. If using a toothed belt drive system, occasionally spray the belt with a conducting
graphite spray available at most electronic stores.
b. Turbine-powered models-
i. Ground the outer shell of the turbine to another area on the unit. We suggest the use of
a grounding or anti-static strap to do so. These are available at most electronic stores.
6) General information-
a. When assembling the aircraft, avoid using metal clevises with metal control horns/arms.
b. Ensure that all screws, etc. are routinely checked for tightness and proper fit. If these items
come loose, there is a possibility that they will create model-generated RF.
Range Check-
A complete and thorough range check should be conducted prior to each flying session. For the proper procedure, please check our web site at: http://www.futabarc.com/faq/faq-q331.html.
Please note, with only the largest section of the transmitter antenna outside of the housing, the R5014DPS should have a minimum range of 100'.
If your aircraft does not meet this minimum distance, we suggest unplugging one servo/channel at a time- checking between each. This will allow you to determine whether any single channel greatly impacts the range. If so, this channel should be tested once again after a filter has been installed between it and the receiver. If the filter doesn't improve the range of your system, closely inspect all servos and wiring on this channel.
