I'm sure this is a fine receiver, but according to Flysky (https://www.flysky-cn.com/ftr8bspecifications-1-2) it is a single antenna receiver, not dual as indicated in amain's description. Be sure to use an antenna tube.

I’m running this Rx in a couple drift cars. I plan on buying a few more and converting all my toys over to Flysky. Update. I now have 6 of them.
