years However discovered various interpre tations about should performed After number telephone calls other discussions consensus has emerged about should done both stall turns should performed yawing airplane upwind example maneuver initiated pullup roll right first stall turn would require yaw right second roll right -outside loop third /4-roll right would precede left course initial -roll left would require yaw left right respectively two stall turns Im sure other maneuvers new FAI lists will greeted similar differences interpretation Doesnt seem new program rushed upon us very short warning little confusion years slow roll maneuver used fascinate terrify same time first performed very high altitude scared death Now very comfortable generally earns high scores Advanced class three secrets doing good slow roll Id like share first secret involves use either slow roll button dual rate ailerons roll button does nothing deflect ailerons small amount aileron deflection properly adjusted airplane will perform roll five seconds using dual rate ailerons low rate should adjusted give fivesecond roll stick held way side second secret learn coordi nation rudder elevator Since slow roll right start bleeding left rudder airplane has rolled about 450 start taking out about 1350 also down elevator eased down elevator comes out about 2250 right rudder comes right rudder removed 3150 450 before completion roll airplane stops rolling just soon let go stick important secret should come no surpriseyou must practice did lot dry flying using nothing transmitter imagination before daring try first real slow roll difficult things learn use proper rudder direction time flying friends heard mutter Left rudder first dummy people really admire ones use neither roll button nor dual rate ailerons Perhaps Ill never good time didnt think Id ever able slow roll either Ron Van Puue 12 Connie Drive Shah mar Florida 32579 RC Soaring/Pruss continued page 23 become synonymous RC staged
