Jumper T12 Plus with SIYI FM30 module
 

Today I received the SIYI FM30 module with FR receiver. I tested it with the Jumper T12 Plus.

The only problem was the rotary switch with which you select PPM, UART or S.BUS, because in the manual downloaded from the Internet it should have had an indicator arrow, in reality, it is difficult to distinguish. So I made a few attempts, until the green RF LED on the module also lit up, and a few more attempts, until the servo started to move in accordance with the station stick. Everything went well in the end.

In the Range test, everything seems fine, moving to the farthest corner of the apartment, thus separated from the station by several walls with iron through them, the RSSI decreased by 1.

The only problem is the size and weight of the receiver, almost 23.5 of grams (in the advertisement it is said that it would have 20 grams - quite heavy anyway).

I just wanted to point out that this module works very well with Jumper T12 Plus, with OpenTx 2.3 - the latest version.

P.S. Do you know which vario/altimeter I could use without too many complications?
