i found that a good radio makes all of the differance to a good time flying or not i recomend that you buy a good tx and rx if you know that you are going to keep flying
radios that i recomend are:
spectrum dx6 park flyers only 2.4ghz
spectrum dx7 full range fly anything type thing2.4ghz "i love mine"
any jr tx
but i have no idea what it going in with your plane? yes slow sticks do have a lot of power and they can even pull verticals.
have fun hope you work somthing out with your plane
