I have a Ko Propo EX10 Helios and absolutely Love the damn thing. Built in 10 model memory, expandable to 25 and so many customizable features that it can be a bit intimidating at forst. however you don't NEED to tweak every tweakable option for it to still bve a great radio.
It's also module based, so I use Spektrum 2.4GHz and also have an AM mini-Z module that I use for the occasional mini-Z racing as well.
