Hitec servos might not fail, but 100% the are the least accurate servo made, they don’t centre. I’ve test flown models and without being told what the servos are, said to the owner to junk the Hitec servos…how did you know they were Hitec.
You will never trim your UF with Hitec servos.
JR Propo made the best servos ever, so Sir you clearly don’t know what you are talking about…
