Most people are using servos rated in the 300-350oz of torque. Obviously more is better. This one is the one I am running on my Bully, its a great servo for the price. http://www3.towerhobbies.com/cgi-bin/wti0001p?&I=LXNRN6 333oz @6v |

500! The Hobbico is a great servo but this time more is better. And the Hitec 7980 is more $$ but definetly worth it. |

Do you guys experience heat coming from the Hitech servos? Anybody temped them in harsh circumstances and seen them over 140F?

Hobbico List http://www.hobbico.com/radioaccys/hcam1000.html Hitec List http://www.hitecrcd.com/files/2010%2...%20Catalog.pdf Futaba Analog http://www.futaba-rc.com/servos/servos.html Digital http://www.futaba-rc.com/servos/digitalservos.html Tower Hobbies usually lists the torque for the servos they sell, so google tower hobbies and the model number. Just me, but I am cheap because my kids run all my rigs, so things usually get broken. I usually run used servos. Most of my 1.9 scalers have Hitec 645's that have NOW been waterproofed. My JK has a 1/4 scale 805BB in it. Huge, but 343oz, and I got two of them for $20each, NIB. Last edited by sweli; 09-03-2010 at 02:08 PM. |

I always found that fade happened around 140f on the case, that is why I ask.

Mudder you need a 300+ oz servo this is the most abused piece of equipment on a competitive RC crawler, to skimp here would just cost more money down the road.

| Sneak peak of your new steering on your super?? Nice. Oh, and keep dreaming!! They're already spoken for!! Oh, and about the 2.4ghz...yes, new radios and goodies. It's about the then new module and receivers we have out. As well as our aircraft stick radios. |

| Yes, more is better. Most run a separate BEC for their steering, I do. Then they power the receiver and dig switch from the esc.

edit: But most run at least 3S li-po, at which point you would need a BEC to regulate the voltage. | |
