Those are what I use on my Greenley, and they seem to do the job well

The Hi Tec 645 is what we use in all our Greenleys. The digital version is the 6545 but it is really not necessary on models like the Pawnee. Where more torque is required such as the rudder (where loads can be high due to the towline dragging across the surface if the glider is out of position) we have had good results with the Hi Tec D645DW.

I'm getting along fine with Hitec 645s in my 1/3 Cub, although it's electric so they have an easier time with less vibration.

All these servos are perfect, I'm using 625 and 645's, the new D series wide voltage, metal gears and 2S compatible so no regulator required :)

Because they're next gen digital, they are really programmable and have soft start which is fantastic.

The only bummer is Hitec have changed to 25T splines for some reason...

I found that with the large tugs and the like, these servo arms gave me a much more confidence in the high torque areas. Nylon arms just didnt do it for me especially on the Greenley flaps
