Cooltech Corona C4FA 4 Channel Futaba fasst SBUS Waterproof Compatible Receiver for 3PK 4PK RC car Surface C1 Mode RFA04C

Unfortunately doesn't operate in high speed mode, only low speed, and even at that speed, will disconnect and even had one runaway (thankfully indoor dirt, not outdoor nitro). Tried with 4pks and 3pm-x in c1 surface mode. Have 4 futaba RX that work fine with any of those transmitters. Clearly just buggy.

I purchased 10 of these receivers for a Futaba 3pks radio with a Futaba FASST module. The receivers binds but after that... Steering: servo turns one direvtion and goes full lock, and then nothing else. Esc: nothing. I have tried multiple of these Corona receivers, none of them work. The Futaba 3pks and Futaba 2.4 FASST module has no problems with Futaba FASST surface receivers and OrangeRX FASST compatible receivers. So if are looking for FASST C1 surface receiver, look for something else.
