The S132H was popular as well...mostly at the club level. I remember those days as well. Most of the pro drivers were running the Airtronics servos though.

My 1987 RC12L, with optional carbon chassis, still proudly sports its S132H!! It also sports its Reedy green dot motor, but I'm not now sure if that is in period, or if I just put it in there one day so I didn't lose it!! The speedo and receiver are original, so now all I need is some period cells that still work - fat chance...

(Sorry, not trying to turn this into the 12th retro thread!! )

Actually many racers are now using the Kimbrough medium sero saver (the one with the inserts) because it does have the stronger spring. The TOP and SpeedMerchant cars even specify it in the instructions, not sure about other kits

The problem I've seen with the larger servo saver on many cars is 2 fold...first it is too long from from the center point to the ball stud so you have to limit the steering throw much more. And 2nd because it is longer it is more difficult to get the proper angle on the steering links. I've tried the medium one in a pinch but really don't like to use them.

You mount the ball studs on the lowest holes on the medium saver, that's actually shorter than using the middle holes on the small servo saver, so the angles and throw work out better. And the spring doesn't fail as often

I guess maybe I don't hit things as hard as I thought as I've rarely ever had a spring failure with the small servo saver. I think I've had maybe 2 in 15-18 years and those were due to the servo saver coming apart when taking it off of the servo. Of course I don't get to race 1/12th nearly as often as people on the mainland so that could be part of it.

We don't get nearly enough of it here either! Of course to me every day would be about right

I have busted a few of the Kimbrough 114 SS in hard wrecks, especially in boosted 13.5. Even with the CF/plastic braces, I have had the whole assembly fly apart. I guess I am not quite the driver I wish I was. My only gripe with the 201 SS is the holes are about .5 mm too close to the center which causes the ball cups to bind in certain applications/ackerman positions.

I've cracked my fair share of the small servo savers but spring issues not many. Of course I'm slow and run the slow classes and am only getting slower So I don't break stuff as much probably.

As for the holes...I've even used the short holes on the small servo saver a fair amount to get the right angles and tame down the steering.

Hi Guys,

New to the 1/12 Pan cars, I thinking of buying a Serpant S120 what do you guys think of the car?

Also what IFMAR engines (turn) do you guys use for modified 1/12?

Great car with the On-Point chassis.

For mod I run a LRP 4.0 or Trinity D3 4.0. I run a LRP SXX speedo.

I also agree with Mr. Dunn, I have a S120 Tbar car, a S120 Link car, and a ON-Point Link S120 as well, love them all.

Interesting line up for Corallyman!

Hi,
using the LRP 4.0 with the sxx... what roll out do you use?

Thanks

I know these are used by some 12th guys... question is do I need a receiver pack to use it, or will it run 1s without issues? Thanks, trying to decide on something soon (local class is probably going to be 17.5 blinky, small carpet track).
