RE: Hitect 5845
I used the HS-255MG (65OZ analog) mini's in my PL Partner as an experiment flying FAI. They worked just fine with little wear and no problems. The HS-5845 works just great and if you are running a newer TX that allows you to ajust the speed of the servo with the radio,... even better.
Sgsterling is also very correct, make sure the geometry of the arms are correct and you maxamize your linkage set up to take advantage of the servo.
