Can anyone shed some light on what’s happening with them?..I’m guessing they got hit by covid 19 but it seems beach rc and amain have been backorderd since last March?

Some of them are re-branded RJX with different pots and boards, others are built for them, but still by the same factory with some shared components (with RJX)... so my guess it, same issues as many other Chinese factories that cater to the RC world.
