Well that be the $150 question, can it cut it with the cars costing 25% or so more?, Top is fairly new to the race scene, trying to cut it with the big boys that have been around a lot longer.

Time may be the only true answer, but there does seem to be a noticeable amount of guys saying it's easier to drive and setup than a Mi4, and in the US at least it's having some good results against the other big brands, yet sadly I don't think there was a single one at the worlds.

In Stock Class our HK Team Driver tested over 100 batteries,
in MOD Class same had more test & keep now ,
at MOD Motor build-in Xceed 20k Silicone oil
for base to support huge LiPo & Brushless Motor power .

* if used light silicone oil gear life will drop , same other brand plastic gear .

just chucked this on the scale to see how they weigh

they are nearly 20% lighter than a normal ball diff,

U-Pro gear diff with pulley 16.2g

standard ball diff 19.9g

standard spool with lightweight alloy outdrives 9g
ti racing F1 spool with pulley 15.4g

Here is my quick 2 cents on the gear diff (rear) after running for 6 packs this weekend.

From new, I refilled the diff with 20k oil. Felt very soft compared to ball diff but very smooth.
After running through 6 packs at race pace with a 8.5T brushless & Tekin RS Pro combo(Timing Boost 40 and Turbo 10) the diff still felt as smooth as original. Have not yet open-up to see how much ware & tear on the gears though.

During the runs, diff is consistant and lay down the power like a solid diff coming out of coners. Had to change my trottle input compared to a ball diff.
Off power, lots of steering and rear rotates out smoothy.
On power out of corners, like i said lots off power and grip. A little hairy in the beginng because of the added grip. If i was not gentle out of corners, the rear felt like it would over accelerate the front causing it to pull away from the front of the car (rear wipe-out).

Overall. pretty impressed with the gear diff. Might try a lighter diff oil set up and since I bought 2 sets, next week gonna try one in front also.

Did you run it right out of the bag or did you add/change the diff oil?

It was good seeing all the TOP shirts at the race this weekend at Jackson. Would of liked to see a couple more that planned to attend but stuff happens.

The car worked awesome for me all weekend long and allowed me to TQ and win both 13.5 and Mod against a good field. I ran a similar setup that I posted on here about 3 months ago, but I can post it again if anyone is interested.

Thanks to EJ for coming out and hanging with us this weekend on a long trip from Cali to the East Coast. I'm tired today bro.

Here is a video of the 13.5 A main. Schreff doorslaps the Team Manager on the last lap to take over 3rd place and sends him into the infield.

+ YouTube Video

Your car was sick this weekend. Congrats on the two wins. You deserved them both.

He couldn't take the heat, so I kicked him out of the Kitchen!

Once again Larry, you smoke us again at Jackson. Great job not blowing out like me. I think I was still in the offroad frame of mind jumping those dots all weekend.

I noticed that the 1st batch of gear diffs sold had lighter oil. My second diff (i ordered a week later) felt tighter.

I did not try the diff in its orginal oil. I changed it to 20K before running it for the 1st time.
