This video should help beginners with the G-RX8 setup options when you bind the receiver. It also covers setting up the FBVS for voltage monitoring Watch this video to help the drifting vario problem: • Frsky G-RX8 reset drif...
Many thanks - I spent an afternoon watching the servo monitor screen on the tx moving for channels 7 and 8 but nothing at the receiver - I didn't realise that the jumpers were required to enable the channels . all good now, much appreciated
Mate...... You saved me .... great video...... it explained enough to me that i was able to figure the rest out ..... depending on which firmware the receiver is flashed with will give different results as the what the jumper pins acually do ..... it was a matter of methodical trial and error using the info you gave that allowed me to get past this blockage i was stuck at ..... Im returning to RC Gliders after 20 years and all the tech is a slippery learning curve .... Thank-you... oh .... and the bit about testing the voltage output to determine Digital or Analog .... PRICELESS ... GOLD
I sometimes miss the days when all you worried about was not being on someone's frequency. The G-RX8 arrived today for my HobbyKing paramotor. My Jumper T16 screens look like yours.
@@GaryQuiring I'm not sure what was wrong. I started over by duplicating a different model and when I set the radio the sensors showed up. I had to long press the receiver button to turn the vario back on again. Then I set it to a switch and it started beeping. Hooray?
Thanks for the video Gary, very informative. One question though. On connecting the FBVS could you not put some pins onto the open wires and plug directly into the balance plug of the battery as I do now for my D8RII Plus r/x and put some pins on the black and green wires from the supplied plug from the r/x and plug into the servo plug attached to the other end of the sensor? I ask this as I am having trouble getting both flight battery voltage and altitude from my existing D8RII plus r/x. I can get one or the other at the moment, but not both at the same time.
I'm not understanding the question. I don't have a DR8II rx. I don't understand why you want to connect to the balance port? You can use their MLVSS for connecting to the balance port. The key feature with the FBVS is it's hard wired in, you have to connect up the voltage sensor every time you install a charged battery.
@@GaryQuiring Thanks for reply Gary. On my DR8II Plus r/x I put the servo connector end into A2 and the black and red wires of the FBVS into the black and last red wire in the battery balance plug. Jumper plug onto 2 bottom pins of A1 of the receiver and the t/x screen shows r/x voltage A1 and the flight battery voltage A2. I was hoping that connecting the black servo type plug through the small white plug on top of G-RX8 I would achieve the same result.
I have been watching with interest your excellent video for this receiver, I have 2 of them. My problem is that I have a 6 lipos battery and I don't know which sensor I should use to know the voltage. I am only interested in the total voltage (22 v ... 21 V ... etc.) not in that of each element and I believe that this sensor used in the video would not support the 25 volts. I would appreciate any comments.
I have the same interest, I don't care about individual cells while flying. The FLVSS will do 6s but you have to plug that in each time to the balance port on the battery. I would guess there would be a way to change the resistor on that FVBS board to divide the voltage more so that a higher cell count could be used. I would start up a conversation on RC Groups about it, most likely someone will know how to do it.
You should use a MLVSS or a FLVSS I don't know why Gary is suggesting an analogue sensor but both of the sensors I mentioned can be plugged into this receiver
@@richardlong3615 I prefer the analog sensor because it does not require using the balance port on the battery. I don't want to plug that in each time I fly, not only will I forget to do it now and then but the balance port voltage sensors are huge when you fly gliders that don't have the room for it. Plug the analog sensor is under $3 dollars.
i think using an mlvss is a good idea too. total pack volts may be important, but its also just as important to know the lowest cell voltage in a pack because its usually an individual cell that'll go bad or suffer voltage sag as the packs age. the MLVSS is very small and can easily be stashed anywhere in a glider especially if you use a balance lead extension as you can stash it deep into the fuse and tape the balance plug to the XT60 connector so they're both together so you never forget it
Thanks for sharing. But I have a doubt. I lost the jumper cables we use for switching between pwm mode. Can you please give an idea what to do now? If I can purchase it seperately can you please send me a link for that?
Just for clarification. Basically for switching between pwm mode we need to connect those both signal pins by some means. Am I ryt? If it is so can I join them using wires?
@@sanjaybharani5026 Yes you jump the signal pins as I show in the video. I think the manual will tell you what color the LED's should be in that mode, I don't recall.
Hello i have a TX Radiomaster TX16S.G-RX8 I can only connect to the FrSkyx2 D16 status module.But the value of VSpd and ALT remain at zero.Does not move other values running.Firmware is G-RX8_ACCST_2.1.2_FCC.frk.I really don't know what to do anymore. I followed your instructions no change. Thanks for any response
I also have the RadioMaster TX16s. I am using it mostly with Graupner HOTT receivers. When you bound the receiver did you select 1-8 with telemetry? Are you sure you did not disable telemetry on the RX? I don't use the 2.x firmware, so I don't know what they changed (they tend to change the jumper settings often with releases). Can you confirm the RX is working correctly with a FRSky TX?
@@GaryQuiring I also have a Frsky Taranis X9D Plus.No to bind at all.Only at Tx 16s. at status Frsky x2 D16.Value go dawn at zero and stop VSpd and ALT.I have open tx-16s-239-otx(60e1edc1) module status v1.3.1.59.I don't understand that everything works except VSpd and ALT.Even servo work ok.I am not disable telemetry on the RX.I can enable and disable telemetry when enable go to zero and stop.
Good video, but you are a little mistaken on the use of the jumpers, and their reason for use. Out of the package, these receivers are set up for SBUS use. That is what the blue light indicates. It's not the channels 7 and 8 are not enabled. No channels will work if used as a standard PWM receiver if the blue light (default) is on. If you have bound your receiver, and see the blue light on, it is transmitting using the SBUS protocol, and thus will not work if you have servos plugged into any location. Use the jumper to switch protocols from SBUS to PWM. Blue light will not be on, only the green, and your servos should now work
I realize that but the average user they appear disabled by default. Considering this receiver is primarily for sailplanes it's an odd decision for FRsky to default them to SBus as most are not going to use it. I also mention at 1:17 that it's used for servos.
@@petrokemikal It's more cycles per second which can make the movement more smooth. Frankly I can't feel the difference. Unless you are flying heli's (which should be all digital) I would not worry about it.
@@GaryQuiring Ok thanks for the info !! I always wondered if my digital servos were set up wrongly on analog receivers. I had a dlg glider that had excessive jitter on all 4 servos and when I swapped recievers to another they stopped doing it, But I could never tell why that would make a difference.. Maybe some servos just dislike certain receivers.. Never had a problem with analogs, if they worked they worked..
You may have accidentally disabled the vario. The F/S button enables/disabled the vario. With power on the receiver hold in the F/S button for 3 seconds and see if that helps.
Gary thank you for your comment. I’ve been banging my head against the wall with this RX, finally got it bound, and the vario was gone! You saved me another hour of frustration with this comment.
