this is my trouble.
per XPS manual it says the transmitter module should turn green after successful binding, which it does in my case BUT when after binding i power off and on the system for regular use the transmitter module LED flickers fast in green. i do not find any info in the manual and AI in its infinite wisdom says it is in range test mode

i do not know if that should again be solid green so why the flicker?

I have a model set up with a receiver talking SBUS to an X10+v1.  To set the failsafe servo positions I first power up the transmitter and airplane and operate the controls and make sure that the servos are working correctly.  Then I press the programming button on the X10 and wait until it goes off, then blinking alternating red and green.  Then release.

Only thing, when I press the programming button the led never goes off, it just blinks on and off green.  Same behavior with the X10+v2.

It works as described in the manual when the receiver and X10 are configured for Extreme protocol, but not SBUS.

Am I missing something?

Thanks,

Paul

Hello Jim,

It had been a long time and I hope you and your family are well.

I have been working with a new ELRS system.  I'm using a RadioMaster TX15 transmitter and several RadioMaster receivers.  I got an 8-channel ER8GV receiver that I want to put into my sailplane that currently has an RFU and X10+v1.

To begin I configured an X10+v2 to take SBUS as its input.

Then I configured one of the PWM servo outputs on the ER8GV receiver to be a serial port and to output SBUS.  I connected it all up and powered on and it worked.

The X10+v2 green led flickered about three times per second.

I got feedback from the RCGroups ELRS forum that the SBUS errors are there because ELRS periodically sends back telemetry packets in time slots normally occupied by control packets.  My system's overall packet rate is 100Hz for 10ms frames and my telemetry ratio is 1:32.  That means it sends about three telemetry packets every second.  That could explain the three led flickers pre second.

My ELRS frame rate is set to 10ms and the receiver's PWM outputs are set to 50Hz.  The ELRS system therefore sends every other control packet to the PWM outputs.

The setup and servos seem to work, so I plan to try it out at the airfield soon.

Can you think of any reason I shouldn't fly it?

Thanks,

Paul

p.s.  Will your proposed X10+v3 take CRSF as an input?

As a long time user of your gear, I have found it completely reliable, and still prefer it above others.
But is there any point in continuing to follow you concerning new gear?
I know that times have been difficult in obtaining many components, but what of the future?
Is there a future for any new RC gear from you?
Right now it doesn't seem so.

Jim,

You and your family have a merry Christmas and a happy new year.

Paul

Jim,

I hope you and your family are well.

On the XPS website, the X10+v2 includes SBUS and SBUS2 as supported protocols.  However, in the X10+v2 manual, SBUS-2 is not listed as an input protocol that can be selected.

If I connect a Futaba SBUS-2 receiver to an X10+v2, will it work like regular SBUS, only without the telemetry part?

Thanks,

Paul

I just saw this in RCGroups.

Jim,

I hope you and your family are well.

I have a setup with an XPS Nano receiver, and three ProModeler micro digital servos.  Two DS100s on elevator and rudder, and one DS150 on ailerons.

With the radio, receiver and servos powered up with a two-cell 6.6v life receiver pack, I adjusted the aileron pushrods.  While removing, turning and then re-installing the kwik links onto the aileron servo horn, I placed slight amounts of turning force on the DS150 aileron servo.  This caused the servo to make some noises which I expected as it held its position against the loads imparted by my fingers.

What I did not expect was that the other two servos also made small jittery movements when the aileron servo was disturbed.

I never noticed this phenomenon before.  Do you think there may be a problem with my setup?

Thank you,

Paul

Looking at the receiver, it's quite old.

Jim Drew, XPS,

The Xtreme Power systems website announced a few years ago that XPS would be selling both aircraft and radios used over the years for testing.

I just noticed that in July XPS put several RC jets for sale in the RCGroups forum.  I never saw that until now, but I wouldn't have been in that market anyway.

I am however in the market for a radio that you may have used for testing along with a working JR or other type module.

Please let us know in the forum when and if and when you plan to sell your radio inventory.

Thank you,

Paul
