Hey everyone,

Did a few searches, but didn't find much info.......so here goes. I've got a couple of HiTec HS-645MG servos I'm looking at dropping into a shafty-project I'm building. Anyone running these? Any thoughts on their ability to turn LST's with a 6v Rx pack?

Any info would be great..........

The 645's would work on a budget, might be a little weak. Airtronics make a nice non digital 200 oz servo for around $100. Hitec make a dital robot servo with 300+ oz of torque. Either of these would work reallyy well turning big tires. In reference, the 645 is around 130 oz.

i killed alot of those servos. try the jr z650 a little more torque and a lot more reliable!

Aaaah! Don't listen to 'em all!!!!

I run only 645's and love them. I even run them on Digler, with narrowed Jumbo Kongs and they work just fine!!!!

If you can....get the new equivalent Hitec servo with titanium gears.

Thanx for the feedback guys. I've got 'em kickin' around so I guess I'll try 'em out and see how they hold up to start. I'm sure they won't be quite as "sKetchy" as my XTM X-175 servos in my clod...........

They sorta work. I just striped a gear out of one in the rear with a alu servo arm.

I switched to a Bluebird BMS-630MG (which i promptly fried the electronics under water) and it was like night and day. Made the Hitec look like a weak little toy!
