Sport Aerobatics Ron Van Putte WHILE competing Nats another contestant asked able perform such square corners Square Loop Top Hat having jerky straight portions told him secret use exponential elevator adjustment isnt difficult takes little time usually about three four flights Obviously getting square corner isnt tough since takes lot elevator throw trick achieving soft neutral vertical horizontal pieces maneuver straight smooth After adjusting total throw exponential get nice sharp corners straight smooth sides decided try out complete flight surprised made lot maneuvers better didnt seem affect rest caused problem oneThree Outside Loops problem exponential would kick just airplane passing bottom loop causing airplane pitch down tighten Outside Loop abruptly solved problem switching out exponential control elevator Three Outside Loops So now use exponential elevator everything except Three Out side Loops flying has improved Actually elevator control wasnt first place tried exponential Aileron tried aileron because Im nervous flier am constantly moving stick little bit loops always looked ragged because aileron corrections mak ing loops look worse Id done nothing friend suggested trying low-rate aileron loops tried it worked thought about Cuban Eight Double Immelmana both have pieces ioops would benefit soft neutral aileron However require high-rate rolls also roll rate low-rate aileron too slow decided try exponential aileron worked Now have nice soft neutral aileronbut can throw high roll rates want set up aileron exponential adjusting maximum throw give three rolls five seconds adjusted dual-rate control give right amount control authority around neutral fly 48 Model Aviation Dolt right time youll get again Seriously Ron Chidgeys wile holding up shade keep sun out Rons eyes during earlymorning contest flight John luqua hackea away excess stuff inside Laser get weight downso vertical maneuvers would have zip What cavernous space Neat building jig designed Dick Austin built Jim Cheney Culman AL Expert class maneuvers using ex ponential aileron use slow-roll switch Slow Roll way Are other exponential con trols around about rudder Youre probably saying Dont tell use exponential rudder too Well However use takeoff give soft steering commands want sacrificing good steering authority taxiing switch highrate rudder after takeoff because discovered better ex ponential maneuvers re quiring rudder especially point rolls way transition ex ponential controls done Tiporare Id just acquired fellow Eglin Aero Modeller John Fuqua Up until time Id competing airplanes Id built flying improved dramatically everyone gave credit airplane fact Ron Chidgey came up contest lead Expert sald years thought lousy flier youre Youre good flierbut lousy builder Well well find out Im really lousy builder exponential controls real secret improved flying because Tiporare stuffed Nats due radio interference Im now working another Tiporare take its place plan compete using exponential controls Details later Most dont know acquired reputation being able repair damaged airplanes after article wrote club newsletter republished RIC Modeler magazine

fiberglass fuselages foam wing still idea Ed Izzos head see Ed some us still remember Balsa structures easier repalr because new piece can cut put place crushed missing piece other hand never dreamed cyanoacrylate CyA adhesives fast-cure epoxies way back real challenges repair fiberglass fuselages damage Im talking about kind fuselage couple wrinkled big chunks rest lot little pieces As long fuselage reasonably intact two three large pieces theres good chance can repaired first part repair procedure very important fuselage must thoroughly cleaned repair will mechanically sound usually use K&B Superpoxy thinner because cleans up almost everything Alcohol lacquer thinner reasonable job good K&B thinner good way test trace oil see well piece masking tape will stick Masking tape wont stick very well theres minute trace oil surface Before starting actual repair its good idea stand back examine damage Sometimes job can made lot easier doing repair certain order Practicing fitting pieces together good procedure follow setting up sequence repair lot fuzzy edges along break wont join together well trim off leaving pieces can pushed together little no gap along break Try trim it. until thing fits well Look places key repair like stripes paint job make sure repair properly aligned tack-glue small sections CyA small steps between two pieces can use fingers inside outside fuselage align Once theyre aligned tack-glue too Work way around repair reducing distance between tack-glue points until everything glued back together pieces missing will filled later Sand inside fuselage side repaired area wipe fuselage inside out solvent get rid dust finger oils Put masking tape outside fuselage across repaired areas use pieces about five inches long Stick down end pull tight across
