ive had 2 480 s one oldish one and one new from the factory
i never had a problem with a tail rotor
i have had a main rotor chip light come on when new but it was swarf and did not happen again, my engine never stalled [thank god] but its a allison 250 c20w nearly the same as 206/500 cant see this is a enstrom problem
i never had a trim failure on both 480s
and i didnt have any problems with belts however i do know of someone who did
helicopters all have limitations you dont use a robbo with 2 big men in a hot and high place with full fuel whoever bought this heli should have read the opperation manual before buying as it seems its not very suitable at this height[a lot of other helis would have the same problems]
this experiance was gained in 450 plus hours in 2 enstrom 480,s and approx 400 hrs in piston enstroms
enstrom are not the fastest to respond but 2 months aog sounds a long time i have not had to wait anything like that
you want to ring bob tuttle at the factory and tell him ,he has always sorted out completely any problems ive ever had
i am also a satisfied enstrom customer having 4 pistons before that
i changed my helicopter to another make to get a bigger heli
