Jr ds398hv

I used the new JR DS398HV servos in my Perfections in South Africa. I found there was a temperature issue with the trim on the first batch of the origional JR DS388 HV servos and they did not center very well. The new ones are awesome! They seem to use different model names throughout the regions of the World. Here is the link to Horizon for North America:

I have MKS servos in my Maxa and have had no issues but they do not make high voltage servos as yet. Very good servos! I run a 4 cell Elite NiMh in the Maxa.

I am a convert to LiFe packs (Hyperion 1450mA).Never liked the idea of a regulator.

RDS frames and splines are available for the JR's for my new Fosa

The Freestyler has traditional linkages, no RDS.
I need servos for both wing and fuse.
