Any spy photos? Glamour shots? Press releases? I'm sure it'll be quality and have a decent price point.

Just picked up a set of the V2 Sweep F1 mounted sets. I have the original ones and they are great for display, too hard to race. I know the new versions have been out for a while, but was afraid to pull the trigger. With cost in mind and after reading some of your reviews here, I settled on trying supersoft rears and soft fronts. Out of the pack, they are a lot softer. I'll have them on track tomorrow night, but they will need some clean up and minor prep first. They have a tacky transparent form release coating on them. For the price of a set, It's worth the trial.

For everyone who battles having the rear end "diff out", Fenix Racing has just announced a gear diff for F1 cars. You will be able to tune your diff action with different viscosity fluids, just like TC diffs.

Are you sure it can be tuned with fluids? It's not sealed like a TC or 1/8 scale diff. It reminds me more of the gear diff that came on the old Kyosho F1 cars in the early 90's than a sealed gear diff that other classes run today.

Looks sealed to me. I would like to try one.

It's tuned with grease which should work fine. I am trying to think how they could seal it to hold fluids reliably without Orings. Either way, I would love to try one if they are reasonably priced.

Enclosed and sealed are two different things. Like racenut123 said, grease would work, but with no o-ring or seal, fluids would just leak out everywhere and make a mess.

Regardless, it still reminds me of the old Kyosho diff, which was garbage.

New back into R/C after about a 15+ year hiatus. Trying to gear back up, now with 2.4 radios, all the brushless stuff (esc's motors, etc) and LiPo batts.

Have a couple of questions, though.

Need a good charger, would like to charge at least two at a time, recommendations??

Where is a good place to get f1 Foam tires at (for Tamiya F104 and TRF101)??
Also, have an AE 12R5.1 1/12 scale - same question, even though it's not an F1??

Thanks!

I imagine they would take what works best from the most winning cars and implement that into their car. There was stuff floating around at TCS this last weekend about the car. It's a win/win as long as they don't try and reinvent the wheel.

Ok, I think I've to say something to clarify something on my job.

It's "enclosed" but not "sealed" and fluid... well...somehow we've to find an agreement on what is a "fluid"....

The nut + cone springs on the end of the axle are used to adjust the end play of the differential assembly. You’ve only to tight it until the lateral play is eliminated and the teeth are properly engaging.

Then... you can run the diff dry, I'd even suggest to do one "easy" run with the diff in such condition, this will help you in understand your diff behaviour... of course we're speaking of a differential, not a Torsen or a limited slip diff, when one tire has no load, it will get the full amount of torque, as usual...

Most of the drivers have seen a touring diff, filled with thick oil used to “slow” down the diff action, i.e. not to having a wheel spinning free in a given condition.

F1 are different from touring. Diff should be light as possible and having some “liquid” rotating will only make everything worse.

So… “Fluid”… I personally find fluids of 500.000 to 1.000.000 weight to be perfectly suited in most of the occasions. You need just some small dabs on the ring gears, just enough to make a “light” film over the rings.

If you test the diff before starting, after an usual box rest, you’ll find the wheels “sticky”, almost solid… then make an easy lap or two…. And the fluid will be warm enough to do his job, slow down the diff action.

One Million it’s a perfect choice for ETS style carpet, probably a little high on asphalt but we found the cars just “lovely” also with it.
It’s a “point and shoot” situation…



Any question, feel free to ask!

And there you go....straight from the mouth of the man who made it. ��
Thanks, Giorgio!

I still cringe at manufactures using radial bearing for an axial load.

Somehow.... I agree and disagree at the same time.

A standard bearing can withstand light axial load, and in this situation is very minimal.

I've had the first prototypes running since the late end of 2014 and I went trough several drawings and versions, from "open" to "almost sealed" version.

In all of those I use a standard bearing with absolutely no bearing issues.

Anyhow, the bearing there is a super common for F1 drivers, 11x5x4

I guess for your geared diff, there isnt a need to have a huge clamping load like balled diffs ensure the diff doesnt slip and adjust how tight or loose the diff to suit track conditions.

You might be right the bearing can withstand light axial loads, but it will not survive the impact loads when cars are slammed against walls or traction rolling. I cant even remember the number of times my diff crapped out because that bearing was destroyed. Ive since replaced with a 30cent thrust bearing and have survived 3 8 hour track session without even the need for a rebuild.
