Servo Questions
 

Hey I'm new to the rc crawler world. Ive bought a 1/8 RTR Madtorque from Exceed last winter. Just bought it to play with and screw around on some local rocks. Recently I added 4ws to the crawler and my first run with it I cracked the plastic housing inside the servo that goes over the motor gear.(on the front) The original Servo was a crappy 9kg with metal gears. I figured it was because it was almost a year old and its stock and most stock everything is crappy. So I bought a 12kg servo with metal gears. Installed it on the front. My 3rd run on this new servo and I stripped one of the metal gears. Boooo. So I am to wonder, Is this all because they are cheap servos and I should invest in a better servo like hitec or something similar. Maybe with titanium Gears? Ive done some research and I see alot of guys run T-Pro just for the fact they are half the cost of Hitec. And I am curious why is it the front only? I havnt had any issues with the rear steering yet. I am currently running 2.8 tires with no weights and my rig is fairly light. Its a MOA Rig. Ive checked to make sure nothing was too tight, as far as my steering knuckles and tie rod / links. In case it matters, I am using a NIMH 6-Cell Battery Pack 7.2V 4000mah.

So would I be better off on getting a servo with:

Generic Brand Servo

• Torque @ 6.0V: 220oz (16kg), Torque @ 4.8V: 206oz (15kg)
• Speed @ 6.0V: .16 sec, Speed @ 4.8V: .18 sec
• Weight: XX / XX oz
• "J" type connector with approx. 5" wire
• Standard size servo

Or something like this:

Savox SC-1256TG High Torque Titanium Gear Digital Servo .15/277

Whats the difference between analog and digital?


How about:

I am leaning towards something with Titanium Gears since I stripped the metal gears out of the last one.

Thanks for helping a Newb.
