Details

The D8R-II Plus is a slight change from the older D8R-II. It allows the user to select an internal or external voltage sensor. The D8R-II did not have an internal voltage sensor. The internal voltage sensor is a nice feature for our glider and gas pilots, and the external sensor is great for our electric pilots.

Compatible with FrSky two way telemetry modules: DFT, DJT, DHT, DHT-U

Specification:
Dimension: 55*25*14mm
Weight: 12.4g
Operating Voltage Range: 3.5V-10.0V
Operating Current: 100mA
Operating Range: 1.5km
Resolution: 3072 (>11bit)
Servo Frame Rate: 18ms (FS – Normal Speed Mode)
                                9ms (HS – High Speed Mode)

Features:
Two external analog telemetry ports (A1&A2) and one digital data-stream port (Rx);
When side port pins of A1 and X are connected by the jumper, A1 will change from external analog telemetry port to internal built-in battery voltage sensor;
Convenient to upgrade – no need to open the receiver’s case when upgrading;
Two switchable PPM modes - FS mode and HS mode;
Alarm warning on low voltage, poor reception, etc.

Warning: Battery or servos are NOT to be plugged into side ports (A1/A2/Rx), otherwise damage may occur.
Warning: HS mode is only applied for high-speed digital servos. Other servos should select FS mode, otherwise servos will get hot and may burn out.

Great feature packed Rx Review by Greg

Just flew this Rx with 400mm antenna extensions and my DJT / 5 db antenna equipped Turnigy 9x out to 1.5 miles with no issues at all.
Aloft ships fast and has good prices. (Posted on 7/7/14)
Fast shipping, thanks! Review by Michael

The receiver works great with the frSky module in my 8U transmitter. Thanks for the fast shipping, received in three days.

Thanks Aloft Hobby. (Posted on 3/18/14)
Great RX but NO MODEL MATCH Review by Russ
Quality
I wish I had done my research on this rx. I bought several and they are working perfectly with telemetry and all.
BUT, I didn't even think that it wouldn't model match with my new Taranis Tx, it doesn't. FYI.
Note From Aloft - You will want to use X series receivers for the matching feature. (Posted on 2/25/14)
Good receiver Review by Martin
Quality
Very good receiver and telemetry is very good to be able to know when battery is empty.

NB: This receiver is unusable when used with a HK401B gyro. It's impossible to be able to use this gyro with this receiver without having tail wagging all the way (and yes this gyro was working flawlessly with an orange receiver). (Posted on 4/6/13)
Still the best Review by RC ACE

Used my second DR8-II plus receiver in a Big Stick with the DFT module. Worked flawlessly in any orientation and at normal distances
when flying a large plane. No missed frames reported by telemetry I'm convinced there's nothing better at any price. (Posted on 1/29/13)
Good Product/Fast Service Review by John
Quality
I'm very pleasantly surprised at how quickly the 2 modules with 2 DR8II PLus I ordered showed up. The Aloft guys respond to orders very quickly. I have been very satisfied with the range of these receivers as well. (Posted on 1/24/13)
One of the best on 2.4Ghz Review by RC Ace
Quality
I have used the DR8-II Plus with a DFT transmitter module in a Futaba 8UAF transmitter. Easy to bind and connect standard servo connectors.
Have 16 flights without any loss of signal when installed in a Sportster aircraft. Just ordered another receiver from alofthobbies. Arrived three days after order. Plan to put it in a BIG Stick. (Posted on 9/23/12)

Product FAQs

Can you tell me the difference between the 8 channel D8R-II and the 8 channel D8R-II plus?

The Plus is the newer of the two, and they are identical in every way except the Plus has a built in voltage sensor to monitor the receiver power source. This is very great to have if you are flying gas or gliders. The voltage sensor can be turned off with a jumper. This is handy if you are powering the receiver from a BEC (battery eliminator circuit).

In combination with a DHT transmitter module, will the D8R II Plus give a loss of signal at the transmitter as it is or must some sensor be plugged into the receiver?

Yes, all of the telemetry receivers will report the signal strength (RSSI) back to the transmitter. No additional sensors are required.

Where on earth do I plug the leads from my UBEC on this? I understand that the battery is not to be connected to the side ports, that only leaves one of the 8 output channels.

Yes, that is correct. On most receivers you can connect your power source anywhere you like. You can use an open channel, or if you are using all the channels, then just use a "Y" or splitter. The plus (red) and minus (black) are shared for all channels.

Is the antenna on this receiver replaceable?

Yes, you can replace both of the antennas. The stock length is 150mm, and we carry a variety of different lengths to help get the best location for your model.
