The biggest problem I have had is in a 4wd off road, sedan or 12th scale. pretty basic servo usage here.
with the other servos costing $80 to $120 and hitec comming in at $35 to $60 why not give them a try.
In my years of racing I have had 9 hitec servos new in the package over the counter from hobby shops. 4 failed out of the box, 2 more failed on the first day leaving me with 3 that made it more than 24 hours. I wont even talk about others I have received 2nd hand because I have no idea the abuse they have been through before I see them.
I will say hitec is very good at sending replacements..... bad ones.
Yes I know how to trim my radio, no I dont try using mini servos in off-road.
