You should go to your local hobby shop and pick up all the controllers and see which one you like the best... I would suggest a KO PROPO ex-10 helio with a spektrum pro and a liop battery it make the radio extremely light.. I have raced with all the spektrum radios and a m11 and i really like the ko propo with a drop down wheel they are expensive but worth it because you can use it for years and years and they are very durable...
