gears etc much will replacements cost 5 Are special tools included Check instructions confirm 6 Is helicopter really what want Some folks gotta have new stuff Are Assume now youve bought used helicopter Use instructions perform radio/engine instal lation also critical examination builders techniques Look correct some common problems 1 Nuts bolts installed properly lock-tite lock nuts washers used appropriately 2 Rotating parts properly aligned lubricated Check particularly engine fan/clutch assembly alignment clutch housing Also check proper gear mesh Are gears chipped 3 Wood parts properly assembled wooden parts rely glue rather fit strength Are exposed wood parts fuel-proof 4 Pushrods installed allow ex cessive slop pushrods should routed servos directly control minimum bends 5 Excessive modifications Check structions remove mods unless abso lutely necessary safety Rebuild fac tory specs 6 Improper set-up controls and/or rotor system Recheck instructions confirm set-up points followed 7 Bent main tail rotor shaft crash induced 8 Main tail rotors balanced unequal length see photo above points directed buyer used machine may also find few points worthy con sideration particularly after first crash After machine new Gregg has found proper main tenance absolutely necessary flight trick has learned new parts always necessary instance recent mishap resulted bent main rotor shaft Rather buy new Gregg shaft straightened local machine shop $400 Another tip check clearance nylon gear bearing support block side frames ala Helibaby Revolu tion see Fig Although spacer washer installed found wear pos sibly heat generated bearing caused spacer drawn partially nylon thus reducing clear ances As rpm lift approached lift-off point main rotor shaft gear pulled up against bearing block side frames additional friction reduced rpm point helicopter would barely continue hover same time torque increased much tail rotor could maintain heading Sound familiar correct problem insert additional spacers insure clear ance Remember friction/drag will de crease rpm increase torque hel icopter mechanical friction aerody namic drag due excessive rotor pitch will probably show up first tail rotor anti-torque rotor response Next month Ill go detail about helicopter set-up Meanwhile build some extra blades recheck align ments try again Rules have arrived time rules reward machine capability expense pilot capability perform pre cision maneuvers So some events ing run modifications take account witness following letter Norm Holland Helicopter Event Director Tangerine International Meet Dear Dave would appreciate receiving sup port column Tangerine Helicopter event year have pushed Tangerine planning commit tee two full days half days last year working hard make helicopter event perma nent portion annual meet takes participation As know Tangerine big meet two half days pattern half days Formula day stand-off scale two days helicopter total four days Helicopters will flown off site country club setting AMA maneuvers will flown AAA AMA meet however going modify expert free-style category want upgrade fly ing try open up types helicopters just two fully aerobatic models plans final writing plan limit se lected maneuvers six within four minutes will give time per form maneuver just try get quantity fly like drunk bumble 98 Model Aviation
