Authentic RC - Jeff McGraw
October 18, 2016Application(s): Axail Wraith Steering servo front for crawler. mounted with 2 or 3 inch arm and used to dump the bed of a Tonka truck.
Comments: I have used and abused this servo over the years off and on and I was never in a situation where I needed more. I will mention that most need a BEC to run without brownouts. VERY WELL MADE AND AM TESTING THIS THROUGH ASIATEES.COM DISCOUNTED ITEM BUT WILL PURCHASE AGAIN ANY DAY, I JUST HAVEN'T NEEDED TO. thanks CYS

September 11, 2016Application(s): 1 as an RC crawler steering servo 1 as an RC car servo winch
Comments: I find them very affordable and attractive when I read they have titanium gears - however, sadly, only yesterday one of them lost it's gearing :( Steering servo only working to one side. Will not return to center from one side!! Very unexpected!!
