The more torque the better. Don't worry so much about speed in a truggy servo. You really should be looking for closer to 400oz of torque for a truggy. It takes a lot to get those big tires over and hold them there. You might want to up your budget a little and get a good servo. I'm using a Protek 130T at 7.4 volts (355oz.) in my ET48 and it's just barely enough, I'll be upgrading soon.

Ya up your budget a little. Set your end points right and I have servos going on 5 years of racing at least once a week. For truggy I recommend the hitec 7954. Same rating as the 7955 everyone uses but this one is high voltage. Can add a 20$ castle bec(or adjust gen2 rx8) to give it 7.4 volts putting it up over 400oz opposed to [email protected]

200oz is plenty. If 355 isn't enough you've got other problems. I have been running an Associated XP DS1015 for 5 years in a Truggy without any issues at all.

200oz is plenty for SC not for me in my truggy. To each their own. There's a reason a lot of people will say 300 at the bare minimun. Of course you can use less for years without a problem but you will get better performance with more. I prefer to keep steering tight and turn through anything. Years of crawling has me needing the most holding power as possible.

7955TG /thread

Durable, strong, fast, just about bomb proof. Yes it is on the higher side but you do get what you pay for in servos. Don't skimp.

You could find a decent used Hitec 7955 for about $50. That's a great servo for 8th scale.

If you need Truggy tires, I've got a used set I'll give you for nothing if you pay the shipping costs. They are well used, but perfect for bashing on dirt.

too much speed will make it feel twitchy. too much torque won't really do anything. too little torque can make the steering "bog down" as it can't turn the wheels well, and that should not be happening.

at 13 I would think you would have grown out of inappropriate "yo mama jokes"

savox sc1256 tg. about 80 dollars, and would be just fine.

for 40 dollars savox SC-0251 is your best bet, but it not ideal, and might not be enough toque for bashing (which is what you seem to be doing)

as others have said, open you budget a little more or save a bit. expect to pay 80-120 for a nice servo in this application.
