What would you guys recommend for a heavy duty servo arm for the HS 645? I broke a stock one tonight just rolling my rig and I dont want it to happen again.

Thanks,
Dan

I'd keep using the stock ones. Better to replace those than to replace the gears every couple of packs. I wish my servo arms would break! And I am using the stock ones.

The 645s are far from indestructable.

EeePee,
Thanks for the advice, I guess I had not thought of it that way. Are you running 645 front and rear? They seem to turn the wheels on mine, but the seem a bit anemic. I would put a better servo on it, but I dont think that there is an indestructible servo.

Have you seen the Hitec Ti geared ones? I saw one in person the other day. Holy crap are they tough and strong. A guy had one on his Revo. Just one. You hold the front tires it moves the whole truck on the ground.

Expensive but tough.

Yeap, 645s front and rear. They seem to be the middle ground between performance, and price.

I started with Kimbrough servo savers, 124s, and went to the included HiTec arms. Then the stripping fiasco started. And I'm really easy on the truck and servos. It's the big tumbles from high up that get me. I have 4 servos, two are always out of commission, and two are always sporting replacement gears. It gets really expensive quickly. Making the ~$40 servo another ~$18 more expensive every time it needs replacement gears. That got old quickly, and I went back to the servo savers. There's a few times the gears didn't last the length of a battery pack. It's the same gear everytime, too.

I have a post titled "Which servo are you killing?" It has a few pictures and a little info on what I've been doing.

I need to ship the servos back to HiTec as I understand they'll take care of them free under warranty. It's just quicker to run to the hobby shop and plunk down another $18.

Be thankful that arm is snapping. I though about drawing a hacksaw across mine a few times to make them weaker. Servo savers suck the life out of servos.
