The Sanwa MT-44 is discontinued but they have theThe MT-5 now. The Futaba 4PM plus is a really decent radio but if you go that route make sure you get it with the R334SBS receiver. It’s $339. but it’s a much better receiver than the 304SB. Futaba also has the 3PV which is more geared for RTR upgrade radios but is a really good radio and like Roelof mentioned the Flysky Noble is supposed to be good, but I can’t comment on it. Check these out. Read reviews and specs, etc.
