I have one on my turmoil.first the reason you need a heli radio is you want to mix the thro with say flaps and put the servo for the v pitch on that .now with flap on the mid of thro is 0 as you go up the moter goes up as so does the pitch more thro more pitch ,comeback to mid now as you bring the thro down engine speeds up and pitch in opt direction goes up.only need that one to -60 or -70 %on pitch.you dont want to try changing the prop dirc at full speed on no foamy I think 35% is ideal to keep you flying.without the thro to change the speed you really cant do much see as the thro and prop change together you canhover ect stop the plane back up etc. my spectrum is the trick i can fly with 40 other spectrums at one time and not get hit or1,000 on 72 cant beat it if your going to buy one go 2.4 ,buy a up to date one the others will be out dated soon.jaybird
