I used a 1258tg in my SC10 4X4 and now in my VE8 and it has plenty of torque for those cars. Kind of overkill for the B4.1

I prefer something .10 seconds or faster in all of my cars. My B4.1 is running a Futaba BLS451 (0.10s and 147oz-in). It's not fast by my standards, but it works for me.

Ironically, my SC truck has an Orion VDS-1007 in it, which is .07s and 138oz-in.

I'd swap them, but I'm too lazy.

damn man. when i inherited a 1258 savox, i even took the time to sell it on rctech so i can pay for a 1257. +1 to lazy. i just wanted to stick the right servo in my TC the first time out.

Oh thanks man sorry i didnt look in the thread better but you helped me alot thanks!!

A slightly slower servo of .10 to .13 would be a good starting range for newer drivers. I've been racing 1/10 for 5 years now and consistently put down faster, consistent laps with a slower servo. The .06 and .07 servos cause me to try to dial steering out with the chassis setup.

Just another view point. Slower servo helps me drive 1/10 vehicles fast.

I agree to a point. I had a servo fail on me and only had a REALLY REALLY slow servo to fall back on (.18 sec).

It's very difficult to enter a turn when you have to start turning before the car actually gets there.

I know this is not much help but yes someone does make them. A guy at the track that runs an RB5 had some from his previous Associated days that I traded him for some hexes that fit his RB5. He thought they were from a TC3 so I ordered some Associated ones for the TC3 but they did not work. Bottom line is that I have a set but have no idea where they came from.

I know this is the wrong forum but does anyone know if the aluminum hexes for the TC3 have changed over the years?

What is the difference between the factory team b4 an the new b4.1????? Would some one tell me???? I am wanting to get back in to 1/10 buggy off road again???

exactly. and i agree 100%.

could that be from a weakish servo? the way i see it is this.... everyone gets a hard on about how amazingly fast their 125-150oz servo is... take that same fast and weak servo and throw your car/truck in a turn and when the chassis rolls and a good bit of weight is transferred on those front tires then its not so fast anymore is it? i run hitec 7955 servos in everything i have simply because the steering feels much more consistent no matter what kind of load is on the front tires. just some food for thought....

Not at all the slow servo was well over 200oz.

My focus is on speed. The 140oz servo in my SC manhandles that thing.

1. They don't make the B4 any longer
2. A lot.

Do a quick search on google and you will find 10+ threads on rctech alone where it lists the differences.

Not worth going with the b4 unless you can find one for $50 or so. Used b4.1's can be had for $125 if not less.

To the best of my knowledge the hexes for the tc3 didn't change but I do believe there are different widths for the 4-6 version's. Give us a picture and maybe someone will know what they are.

Here they are:
