My Orion batteries fits well as well and sits flush on the chassie.

However, it is a possibility that the battery will touch the motor axle if it move inwards, the std battery stop (the little nut thing) is not enough, I use a 5g balance weight as extra stop at the moment, needed the extra weight anyway... any plastic thing would work to ensure the battery cannot come into contact with the motor axle or the pinion.

The only other thing I can think of is I'm running 21.5 blinky class with Sorex 36r's. Medium sized medium traction outdoor asphalt track, track temp around about 30-35 degrees celc.

Thanks.

Try taking some droop out of the rear, maybe a quarter turn or so and add a little droop to the front. You could lay the rear shock down for a little side bite as well.


Try that and see how it works out for you

Thanks.
Also try removing the rear upper inner link shim, so it goes down from 1mm to 0mm

Still having hard time rebuilding shocks to achieve 25% rebound. Tried loosening the bottom cap as well with not much luck....for me I need to try many times to get it right. Any other suggestions? Use different brand bladders? Must be easy trick to get it right every time

Personally I wouldn't bother. You'll spend hours trying to get a specific amount of rebound, then after a couple of runs on track it will have reduced anyway as the excess oil gets forced out. Unless you're a pro changing your oil every couple of runs it's not worth the effort. It's much more important to have all 4 shocks the same than it is to get them to a specific rebound.

With the T4 it's easiest to build them by putting the bladder onto the shock body, then fitting the cap. Fitting the bladder into the cap makes it very hard to build them with consistent rebound across 4 shocks.

I build mine with 100% rebound (so put the bladder on with the shock rod fully extended) as I don't like shock building, and the extra oil in there means longer between rebuilds. Mine have now done about 40 runs and are down to around 10% rebound, still with zero air in the shocks.

Definitely some of the best shocks I've ever run, on a par with the Tamiya TRF shocks now (maybe even better; it's still early days).

Just like guy above said, I wouldn't even bother with trying to get the rebound on the shocks just right. Plus, if you have to make an oil change at the track, what are you going to do? Spend hours getting them just right? The new Xray shocks are awesome.

Maybe that is why I'm trying to get my T4 all sorted out. I usually build 100% rebound on all my other cars, but tried 50% on the new T4 build. Don't think I like the way it feels, or maybe all four are not rebounding the same. I feel my car is quicker than my Photon but its harder to stay consistent. Making more mistakes than I should versus my previous car.

Going to redo the shocks this week for 100% rebound and do some testing.

Thanks for the tip.. I only build the shocks at home cant be bothered to do it at the track as I only play for fun. Just thought how hard could it be to do the dam shocks lol. 100% rebound is easy ill just leave it at that and let it slowly drain out on its own

Got to drive my new t4 today on carpet, this car is awesome and it goes and does what you want it to do right out of the box... I'm not the best driver but this car is going to make me a lot better.. IMO it's a little soft and had too much roll for my likeing, I have most of the option springs and a boatload of different oils (all XRAY), can someone point me in the right direction?
Med track , med traction, sweep 32's

I would try 2.7/2.5 f/r springs or try reflex silver front and rear, solid combo.

I also like 350 or 400 cst oil all around to settle things down a bit.

2.7 & 2.5 seem to be the most common on carpet.

I use 450 oil, 2000 in diff. I haven't run those tyres but seem to recall others had 2mm on front upper inner link with 0mm at the rear link.

2mm front upper inner and 0mm rear upper inner? What about the outside? Stat box setup?
