Radio Control: Aerobatics

RADIO CONTROL AEROBATICS U fl ~I new AMA Competition Regulations 1999-2001 has just dropped out mailbox landed desk write always exciting time us serve Contest Boards Advisory Committees filled gtorious hope have finally achieved totally unlikely produced rule book errors sans dreaded gray areas Such forlorn hope seldom survives initial reading never outlasts first contest season Stil lwe try time looks like good solid try best several rules cycles should because major changes actual form events table What table mainly finetuning some light housekeeping designed clarify intent ctose loopholes said few important changes Perhaps visible change renaming former Novice Sportsman classes Novice now Sportsman Sportsman now Intermediate maneuver schedules remain same accumulated advancement points remain accumulated names have changed protect something other main effect will some scoring software will need updated few old scoresheets will need class titles crossed out rewritten rose other name se political winds may make further change necessary next rules cycle Sportsman Sportsperson will deal time comes Clause 431 provided exemption model weight power size old Novice class up AMA-legal 55 pounds has removed now Noviceerr Sportsman will fly models same size power other classes Fair widely felt traditionally least-able should provided continued means maximum damage allowable under insurance restrictions assume judges will now thankful least somewhat less terrified Clause 45 Number Models has replaced Clause 45 Eligibility Models new rule makes legal contestants share borrow repair models interchange parts whatever want within state federal laws governing theft long show up flightline complete model conforms rules CD deems airworthy Another new clause 471 deals temporary marking temporary aircraft AMA numbers temporary pilots clarification has inserted 131 regarding number rounds flown determine winner competitors particular class have flown x number rounds rounds will countfor class competitors another class have flown y number rounds done strictly make obvious what evidently obvious some Clause 147 has added making illegal hot-dog during free passes after takeoff before landing Hot-dogging defined anything isnt strictly trimming purposes Any simple 1800 turnaround may used position aircraft box entry judges opinion prohibited maneuver performed first maneuver following violation will zeroed course AMA Pattern equivalent 15 yards excessive end zone celebration like NCAA version depends almost totally mood flag-thrower predict new rule may cause some discussion little may heated best advice pilots play safe F3A-style takeoff landing sequencesat least until have insurmountable lead Clause 208 has added help perennial sun-in-the-box problem basically says CD should what he/she can see sun isnt box models whether reorienting flightline scheduling competition appropriate time after dark presumably key word should Bottom line May1999 81 Kirk Wanner kneeling Charley Reed pose Midwest contest last year Sam Turners Saturn good-looking design Big Supertigre 2300 fills nose Dont expect much change local events written mainly big events like Nationals maneuver schedules classes remain untouched except some k-factor changes Masters result two separate proposals k-factor Immelmann Turn goes k 2 because proposal make k-factors same class class identical maneuvers since Immelmann k ortsman Intermediate Advanced now k sters well never mind Masters class ought able babies solid 9 time sleep three-channel trainer same thing holds true Half Square Loop Half Roll Vertical Masters k w k cause what Advanced class other words now pays same simple Immelmann Go figure wouldnt try three-channel trainer Several other changes Masters make bit sense Vertical Eight Middle Pilots Option has bumped k 4 because difficulty pilots continue have making two loops anywhere near same size dreaded Two Rolls Opposite Directions goes k 4 similar reason Master pilots arent doing terrifically well Overall total k Masters goes 66 68 impact goes little beyond obvious scoring software changes Putting additional emphasis two maneuvers pilots having trouble should make little easier judges separate best rest should also cause pilots rethink practice time regarding trouble spots Judges Guide section also contains few revisions Under Bb Smoothness Gracefulness criteria pitch changes has revised include requirement model show constant radius transitions line line Excessively tight maneuvers should avoided line has replaced Higher marks should awarded flying tight high-G corners done remove differences between AMA FAI judging criteria section D Judging Individual Maneuvers Loops greatly expanded list judging criteria loops part-loops has included list breaks very little new ground mostly collation criteria gathered other areas book presented under heading clarifications worthy note Snaps
