Default No servo saver?

Thoughts on just skipping the servo saver? After one race weekend stock is trashed. Car is otherwise stock aside from bearings. I know the Tamiya high torque is really good, but I have servo horns in my parts box from racing off road years ago and that will save the trip to the LHS, assuming they have it or can get it this week.

I don't know about you, but I tend to feel that my time is better spent than changing gears in expensive highspeed servo's. It only takes one bad day and you'll never second guess yourself again.
The Tamiya High Torque is the only other servo saver I use rather than the Xray X-Stiff Composite servo saver that I run in almost all my cars.

FWIW, when I used the Tamiya Hi Torque servo saver, it wasn't long before it wouldn't return to center when bashing. Since going to a power hobbies solid horn, I've had to change the gears one time in my savox in 8 months of hard bashing, and that was only cause I hit something at very high speed.

Me personally, I'd rather spend ~$15 on a metal gear set when needed instead of dealing with a servo saver that no longer centers properly. I'm sure that issue could be even more annoying if you're actually racing. All my cars now have a solid servo horn aside from my budget TT02, which has a secondhand Kimborough servo saver.

The Kimborough servo saver is a good option if you don't want to run a solid horn; but if you run a solid horn, I'd recommend a robust, quality metal gear servo.

+1

Xray servo saver is first choice, especially when racing. Tamiya is pretty darn good.. does wear.. but moving parts wear.

Iíd rather replace a servo saver than gears in servo. Youíre not just chipping a gear when you go direct, there is other collateral damage that in the long run will ruin the servo.. so unless itís a cheap $20, use a servo saver

Gearing: You need the yeah racing motor mount if you donít have it. The maximum gear combo I have been able to fit in TT02 is 78T / 53T 3.83 fdr. This was with a brushless 21.5. You will need to trim the gear box cover or even cut a hole out to clear the large pinion.

Now with a sport tune however, an FDR of 3.8 will heat the brushes and launch them inside the motor lol.. Iíve experience it first hand. So youíre probably need to gear it to 4.5 fdr tops.

Springs: Try a different brand spring.. yeah racing springs rates are an unknown for racing, so hard to say what you need.

Thank you both for the insite. I did install the highspeed gear set and the Yeah motor mount I had it out this afternoon doing some practice in the school parking lot. The motor was a little warm. I changed to a 41/95 with an FDR of 6.0ish. I will try that tomorrow,
As for the shocks, I have ordered the TRF 55mm however they are on back order, I tried the TRF springs on the yeah 55mm shocks. DId not seem to work well, I could not get the right hight in check . I will try the red rear and blue front from the yeah kit. Hopefully that will correct my issues untill the tamiya shocks come in. I am having a trouble getting no rebound on the yeah shocks.
I am stuck to using the tamiya brushed motors for our club race. We run box stock silver can and chassis with bearings The mod class is bascially any add ons. However Brush motors Torque or Sport tune and the HW 1060 or Tamiya version.

SteveM I will check out your post shorty.



Is there a big difference run the TT02 with the TA05 suspension? I looking to set one up for parking lot and one for carpet.

Thanks

What class are you planning on running first?

zero rebound, you need to drill a hole
in the cap, same is needed with TRF shocks.

when you say right height, is it due to the springs being too soft? Too short? Post pictures we we can help

The TA05 style suspension that comes with the type S if allowed is much better suspension geometry. The arms are longer, better ability to adjust camber, roll centre etc. you also can opt for the down stops which will give you droop control.

Thanks for the tip on the drilling the cap. Are the TRF shocks any better than the Yeah? For my level of racing I highly doubt it.
When I used the TRF springs on the Yeah shocks I could not obtain the ride height. Standing the spring next to each other the Tamiya was a coil or two longer. When I get home I will take a picture.
I found the Yeah Red on the rear and yellow up front worked for a starting point. Using 500cst oil. Sunday I plan on doing a club racing. I will see how it goes.

So far the only issue I have had was a bent turnbuckle in the upper front adjustable arm. I was able to replace it with a Ti one from an xray t4 kit I found. Hopefully that will tighten up the front a little.

I do believe I bought the wrong spring set, thats why I was having trouble setting the ride height on the YEAH shocks.
Correct me if I SHOULD have bought the soft kit.

Sorted the spring issue out. I did not know Tamiya had so many types of TC springs. The one I pictured above is the right one. I ended up using the Yellow (medium) for the front and a Blue soft from the 53163 road rally spring set.
