After a full run with Team Orion SHO 4200 pack, the motor is a cool 50 degree celcius. So it's not overheating, the ESC is also just slightly warm, not hot.

Will rebuild diff as instructions, then test tonight.

Will post back how it goes.

I think it's the new tires- sounds like that was the only thing that you actually changed when performance declined. Foam tires are cut out of big sheets and suppliers don't always use exactly the same material with each successive batch- even if THEIR bulk supplier claims that the material has not changed. So the new tires might have more (or less) rubber content or smaller (or larger) cells. Even if the shore number tests out to the same range, the tires can be very different.

Just home from track.

The car was amazing tonight again!
TQ and won all races, best laptime, best average and new lap record! Had lots of fun and some hard but fair fights on track.

My set up ended up with...
Black springs upfront, standard front suspension but with the 53119 king pins.
Lower damper mount, red spring, no preload, #200 Tamiya oil in it.
Diff got rebuilt as instructions says, new balls again, sanded rings.
Friction damper got hard grease tighted about halfway down, white low friction pads.
Rear pod on it's lowest. New spur gear. (104T) New pinion (21T).
T-bar was firm.
Tires was Zen 38 shore front(old ones, very small) and Zen 35 shore rear(new ones), using Red Dot Trinity tire sauce.

Body i used was Ferrari F310B with M. Shoemaker as driver.

Overall a great evenings racing. Only damage was a 850 bearing on right front got busted after a little incident.

am i correct by assuming it is 20wt? what do you find your results being with heavier oil?

Does the 103rm come with all the parts necessary to convert to the o-ring setup? I see that it has the plastic parts, but how about the o-ring itself?

thanks!

The RM comes with all parts except the washer on the front of t-bar. Just use 2 normal gold thin washers. the o-ring is a normal black one that Tamiya puts in all kits!

I don't remember what oil i had in damper first time i built it, it's a old Low friction Formula damper and not the new one with adjustment. I rebuilt it first with 60wt oil, then after all my problems i used Tamiya's kit oil. They send with oil that is 20wt.

The F310B body is extremly strong, mine has taken quite a beating! Ordered new front wing now, can't find rear wing so i use Tech type B wing at the moment.

I used 1000 paper on diff rings and plain crap Tamiya diff tube.

i just got my 3 racing diff set in, and it fits, but there is a HUGE gap between the nut and where it secures the wheel. i am almost 100% positive it need the thrust bearing there but i am having HUGE problems finding one locally...

anyone have one lying around they are willing to sell?
this si what i need:

i need all washers, and bearings.

a few people in japan have some, but i dont want to wait 2 weeks to recieve...

thanks!

I have tested Hop-up Tamiya tires on carpet. All kinds, hard, medium and soft.
Only tires i have not tested from Tamiya yet is F103R tires. Got a set i will test later.

But the Zen tires we use now have massive grip.
I run 38 shore in front and 35 shore rear, that is my preferred combo.
Others on my track run 35 shore front and 25 shore rear with success. And the best part is, they are premounted! and pretty cheap and long lasting with right care! (Not crashing)

There are no other tire that preform that well if you ask me!

Hey guys, how do you lower the front ride hight? I tried putting in shims as I thought that would be the easiest way, but the tire can not go on. I guess cutting the tires is the only way?
