Sanlianhuan and FlySky protocol

A few days ago I got myself a Sanlianhuan SH 6050, a relatively new, promising flybarless CCPM micro heli I had spotted at my LHS. This ultra-cheap, 100 class bird is powered by a brushed (main) and coreless (tail) motors, sports rotary servos and is very well made - sort of crossbreed between a Genius CP and a Solo Pro 125A. Plastic used for main rotor blades looks and feels the same as new V120D02S, and tail motor is cleverly caged. Mine must be an updated version, or a new production batch, because it comes complete with tail boom struts and horizontal stabilizer which isn't shown neither on the few videos I found on the web nor in various advertising photos on the few sites that offer this heli.

Back to us... I had to take apart the flashy looking, programmable 6-ch transmitter with mechanically operated mode 1 / 2 changeover in order to eliminate a bit of play in the left gimbal, fix the poorly assembled battery compartment, redo many sloppy solder points and paint the graduated gimbal markings, nearly useless until highlighted. I went on and dismantled everything to clean up the fine web of strings from an even sloppier hot glue sealing job, so I could take a good look at the RF module. It's the A7105, same as V911 if I'm not wrong, which brings us to the topic's title.

Other Sanlianhuan products I found here filed under "Supported Models" are all multirotors equipped with NRF24L01 module thus operating on a different protocol. The firm also makes SH 6051, a flybarless FP version of the same bird I got. 6051's protocol is still undetermined.

Moderators or whoever has access to the above mentioned database, please update it. Thanks!

Did you try the YD717=>Skywalker protocol ? Coz SH quadcopter can be flew with this one

@SeBy: YD / Skywalker uses NRF, but he said the RF module is A7105

@HeliOS:
Did you try to bind with FlySky protocol ? (Modded Devo, V911/V9x9 Transmitter, ... )
There's not only FlySky using the A7105, Hubsan does use it too, and there is some chance that SH uses its own protocol or a variation.

Any chance you can sniff SPI traffic on transmitter with logic analyzer?

Opps I didn't read the full message

Not yet. As soon as I lay my hands on a V911 (MT-100, etc.) I'll check it out. First off I still don't own any deVention TX. Truth is, a Devo 10 is on top of my wish list so we'll see. My only Walkera heli came with a WK-2801 PRO, not a deVention.

Maybe, of course. A cross test will sort out that too.

Whoa! I've been trained in basic electronics but that's a bit over the top...

Thank you so much for your feedback.
