Well....I ordered my new servo for my soon to order Tekno eb48 2.0. I was gonna get an AGF-RC servo but I went with the Power hd B4 servo. For the $66 price tag you get a pretty good servo. Power hd upgraded the gears in them from titanium and aluminum gears to titanium and steel gears. So it should be strong enough. I had to email Power hd to confirm this. I like that they come with a 2 year warranty. Should serve its purpose as I am only a casual club racer.
