M3220

Is there a servo tester i can buy from a hobby shop. which are the best for your buck. I have looked on the internet, lots of u build your own and a servo tester # 555. Can i get some input from rc modelers on which brands and models are out there. do they check amperage readings on a servo ??
Any help would be appreciated.

thank you

Amongst other brands are:
Hitec HFP-20 The HFP-20 directly replaces the HFP-10 and allows users to perfectly match servos in ganged applications or customize several other parameters such as dead band, direction, speed reduction, endpoints and failsafe. The HFP-20 is required to program the overload protection features in the new HS-79XX and 50XX servos along with the standard/high resolution setting in the HS-79XX series. The HFP-20 is backwards compatible and works with all Hitec Digital Servos.
Programmable Features Include:
Reset to factory default
End and center points
Direction of Rotation
Dead Band Width
Failsafe Point
Speed (reduction only)
New G2 Servo Features:Overload Protection, Resolution Mode Setting

I've used the Vexa ServoXciter for years. I'm very happy with the results.

Hi Alan,

I have a HFP-20 which works fine on most Hitec servo, but on other Hitec, JR ect, is erratic.

Any ideas?
