Thanks. Today, everything is on 2.4 GHZ. 72 MHZ and 75MHZ as well as 27 MHZ and 50 MHZ are still legal, as far as I know, but you won't see anyone who has been in the hobby for less than 10 years using them.

I still have some rarely used planes that still have 72 MHZ receivers and a bunch of channel 40 and 35 crystals.

thanks for sharing your stick vs wheel experience.
