433Mhz 20KM Remote Control Power Adjustable FPV TX/RX from GLB

Hi !

Do you have any information or experience with this long range system from Goodluckbuy:

I would like to know the connection possibilites to JR and Futaba Radios. Does it have failsafe function, and RSSI output on the receiver?
If you have user manual or any guide about the set up please share, becouse GLB has no more info about this system. The price looks like good. If it simililar to chainlink or dragonlink it would be a nice economic purchase.

that that was not what I expected to see.

Is this Chainlink or yet another Open LRS?

This is the question. I asked GLB but they do not provide information only if i buy the product.
Most important questions would be the failsafe function and RSSI output, and some picture about connection to JR or Futaba Radio ppm output. Of course we should know whether is Open source or have factory firmware on in!

I have found some pics at thanksbuyer, but not new info in the description. We need manual and set up pictures also.

I'd run and stay away from this. Until they can make up some fake specs and reviews telling how far we hav frown.

I know I am making a zombie out of this long-dead thread, but these are still for sale, so I thought I'd post just in case someone is interested.

More information here (Warning, the text found at this link depicts horrible things being done to the English language):

That says (I think) that it does have some sort of fail safe, but the fail safe has(had) a bug where it would sometimes not work on the older versions.

Apparently, there are at least 2 versions of the transmitters, and several versions of the receiver.

Some transmitters have 14 pins, where as the other version has 20 pins. If I decode the writing correctly, the 14 pin version is the newer, 16 channel capable version (requires 2 receivers, and 2 PPM sources on the ground side). The color of the case/color of the RX board does not seem to matter.

There is also reference to version numbers: ff433-RX1, FF433-8, and FF433-R10

The receivers are only compatible with the same version transmitter. Don't buy them separately, and you have to trust your vendor to sell a working pair.

Some things I like about these:

-- Metal transmitter case. If used with a 2.4GHz Receiver, some units with a plastic case have been reported to interfere with the 2.4GHz receiver. (Reported on the DALRC units.)
-- Also better for heat dissipation.
-- Wide transmitter input voltage
-- Lots of settings, band, and power options
-- RSSI Pin -- should be able to connect directly to FC/OSD

I don't think I'd fly with the provided antennas-- at least not very far. And I'd test thoroughly before flying. If you can get these cheap, and then spend more on a good set of flight and ground antennas, you may very well be better off than some of the better known brands with their stock antennas.

Goodluckbuy (seems to be the 14 pin version, with 2 receivers):

Older, 20 pin version, Black
Older, 20 pin version, Red

Claimed 16 ch version (no picture of TX connector), 1 Rx, Black TX Case:
Claimed 16 ch version (no picture of TX connector), 1 Rx, Red TX Case:

If the page above is true/my interpretation is correct, then the version with the failsafe bug costs more than the corrected version.

I'll close with a (greeting?) phrase from the page:

"Look forward to mold friends refresh record oh!"
