I have a bunch of Flydream receivers laying around the 8ch and 4ch, nice compact units. They are also based CC2500, T212, & Atmel cpu. Same hardware also inside the corona system.

Would be nice if we could reflash our old Corona and Flydream receivers to Frsky?

This one ? For 11$ ?

Can you post a picture of it inside ?

For reflash you may need some pads, or at least a atmega chip with proper legs

Never any problems with the Flydream system myself, but not as good as Frsky. Downside of Flydream diversity is not implemented and is not true FHSS, but a 3 parallel channel DSSS.
All receiver have same hardware components, so even the 4ch do have t212 and cc2500. The ATMEL seem to be MEGA98 or MEGA88? difficult to read.

RC beginner
i dont see one in midelics photos so probably he is just using that as a perfboard. hopefully we can get some actual wiring info.

NO Attiny...I used only attiny pinout from the existing board(a hack) to connect to my promini..Yes something like a perfboard

Thread OP
For people having trouble binding with Frsky 2-way RX.
Minor update of the code on first post ...introduce a variable for tweaking easier the CC2500 base frequency..along with a better explanation.
//
static uint8_t fine = 0xd7;//* 215- my value *//give values from 0 to 255 for freq offset
//values from 0-127 offset increase frequency ,
//values from 255 to 127 decrease base frequency
//this is useful for tunning TX base frequency to frsky RX freq.
//
See first post for updated file.You need change values and recompile.
