Steel axle, eh? Can you say moment of inertia? One, it will bend. Two, it's like swinging a weight in the rear. Three, the carbon axles seem strong enough to endure noob crashes. Four, didn't even know that these still exist.

SpeedMerchant has been running soft in high grip since Bruce introduced the linear side springs. Look closely at Mikes car, Bruce drilled out his tweak plate at the IIC and those are linear .18 side springs he used. Most all have migrated to running softer in high grip because it's easier to drive, especially in modified.

The new Xray X12 comes with a steel/carbon axle. Its a steel rod inside the axle. Looking forward to see how i works (i think)

Edit: when looking at the presentation on the Xray site, in one place it mentiones "Newly-designed rear differential has a new way of combining the steel axle with the graphite axle for increased durability", while on another place it says "Super-lightweight rear axle made from 1-piece high-grade graphite rod, additionally precision hand ground to eliminate vibration and run-out".
When I asembeled the car, the axle felt quite heavy.

Doesn't surprise me at all that Bruce was ahead of the curve on the soft spring setup

Just haven't noticed it till the last few months with all the inline cars.

soooo I acquired a rc12L4 and was working on it a bit and noticed its nearly impossible to run brushless motors in the stock pod so i was wondering if there are any worth while conversions making it a link car or just easier to set up for brushless? like would i be able mount say an entire pod from the rc12r5 t-plate car or say one from the xray xii t-plate car?

Any conversion you may try will end up costing you more than buying a used RC12R5.1 which you can get from $80 to $120.

We have one person modify his L4 for 1S and BL and he is fast in a straight line but the car just doesn't handle well.

What is the latest and greatest 1S voltage boost setup for a Tekin RS running 17.5 blinky on a CRC Gen XL

Also. Since I am running bare stock class, is there a 17.5 motor that stands out?

Greetings. Coincidently , steel axles are available (see rjspeed-Bolink ); with an appropriately placed spacer, a bolink style drive shaft can be utilized ( but consider the physics-as stated in the previous reply(s)-) fiber glass axels are also a suitable replacement. Correct me if i'm wrong, Niftech had axels available. It's been awile since i've ordered from them.

Hi, guys never run 12 scale before and thinking about getting the xray X12 and just want to know what stuff to run, speedy, servo, tires, body. Any info will be very helpful Thanks.

WTB ; Team Cobra Lathe arbor - 12th scale 3 bolt

I'm looking for a Team Cobra rear arbor for 12th scale 3 bolt pattern wheels. Will pay $10 plus actual shipping.

Thanks!

If you are running Blinky then you have zero boost. The RevTech 17.5 is supposed to be good for Blinky. I use the D3 in boosted 17.5.

So if I am running blinky 17.5 i can run the ESC and 1S straight up with no booster add on?

You cannot program the ESC to boost the 17.5, but you will need a voltage booster or a receiver pack for the radio equipment. The Tekin will not send more than 3.7 to the receiver on its own.

I am seeing more and more guys running tiny 2s LiFe cells, and I do as well, but there are still boosters to be had and they have the advantage of not needing to be charged. Typically in an 8 minute race I use 27 milliamp hours of my 200mah battery, just for reference, so I can get away with two races per charge but I try not to push it past that.

Yea im running a SP now which adjusts to the 1S but I would like to change to the Tekin to shed some weight. I dont know how much difference it will actually make but lighter has to be better for saving juice on an 8 minute run.
