Yesterday I was checking out my 450 and found the tail rotor servo {JR 3400G} did not sound very good and had a notch as it rotated so I figured "no problem" replace the gears. I call the local hobby shop first to verify they were in stock but they had toubles idenifying the servo after an explanition found out they are on back order for the next month. No problem I'll simply buy a new servo {and have a spare} but found out after another call to Horizon they are on back order also for the next month. the servo IS hanging on the wall in the shop in the four servo multi-pack for 160.00+ tax= 175.00 all for a nicked servo gear!!!

PS I already have spare collective servos
