over transmitter tray However anyone transitioning DPVs RPVs tray will provide much natural control feel Three other reasons using transmitter tray should also considered First fine finger control intrinsic opposed thumb forefinger exploited have using humanizing anatomical feature everything else requiring precision control need RC Some folks supporting X-mitter hands such way thumb forefinger sticks so-called "single stick allows opposed fingers used have no experience grips certainly look advantageous Author Second Hanno Prettner third reason can use true dual control system instruction Combined good three-control RC training aircraft mechanically interconnected student instructor sticks will provide basis training distinctly superior usual method Trainer Tray can hardly imagine aviation exists today dual control training aircraft never could have persuaded instructor student matter fly around passing stick back forth hazards health investment rather less RC flier exist nevertheless can pass stick back forth electronically buddy box reduce crashes considerably crashing certified good thing ever buddy box noncommunicative learning pilot great deal critical instructor-to-student communication nonverbal its done through sticks example instructor may say little up direction stick movement understood student magnitude ofa little ther nebu lous dual controls instructor actually communicates its precise meaning terms both rate distance stick movement moving stick connected students fingers As RC student perhaps observer have ever tried watch model aircraft

st-time student flier hesitant still does controlling Wood frame rigidly ties together transmitter third stick Student fun Did Instructor Yes keep eyes airplane Dual control big training aid very important advantage trainer tray aircraft can safely flown lower alti tudes makes significantly easier student see whats going instructor student comfortable knowledge aircraft wont smite earth due student error Trainer Tray instructor becomes active verbally perhaps because knows what students stick inputs again real time After year use theory behind Trainer Tray has proven practice Its simple
