It is always like this and has been like this from the beginning.
This is my 5th electric car and i never had a problem like this.

Does everybody have this problem with the Type R diffs ?
I haven't seen the diff plates yet but most TC's use only one side of the diff plates. Check you have them the right way around and smooth them out a bit with some 1200 grit sandpaper if they need it.

What kind of lube are you using on the thrust bearing? I use either Associated back stealth grease or the losi brown grease.
I have seen this problem in my car and 9 out of 10 it's an issue with the thrust bearing. Make sure all the balls are still in the housing and you are using a "grease" not an oil.

Good Luck,
Casey

Is the heavy duty thrust bearing standard in the kit?

Yes,

For the grease on the trust, use the losi tan one.

Check if your thrust bearing plates are on the right way too... As mojoman said, 90% of the time its the thrust bearing...

Default Setup

Setup questions abound after a recent trip to the Omaha Hobbyplex and then back to my home track @ Fastlane in Kansas City.

My local club (low to medium bite) setup is based on Mike Haynes IIC setup and works well as a starting point. The rear end is a little loose and I have 2* rear camber and the middle inner camber link (pos.5) now. I wondered if using 2* rear camber and the lower middle inner camber link (pos.8) will help stick the car.

I tried using the super soft setup that I was using in Omaha at our track but it was dumpy in the front with 15lb/37.5wt springs/oil and lazy in the rear 12.5 lb/30 wt. They have no traction @ the Hobbyplex and I tried the 17lb front and 17lb rear setup there and it was a drift car.

Why is it needed to have such a stiff spring on the rear of the Type R compared to every other car I have owned? (Cyclone, FK05, RDX, Pro 4)
I guess my theory is that too soft goes past the ideal traction point(thus loosing grip) and has to recover.

Also what do you guys do when you want more front side to side reactivity without loosing grip in the corners. I've tried thinner shock oil and a thicker front sway bar.

Hindsite is 20/20 but the plex should of kept their old carpet instead of getting new for the carpet nats last year, ever since then the grip had never been the same. To make the front end react quicker try standing the front shocks up one hole

Thanks Matt,

I miss racing w/ you up there. I did gravitate close to Jeff and Andy's setup but I did it on my own. Should have just thrown it on the car from the start and gone from there.

I agree with you about the carpet, I asked about the carpet on a thread here on RC tech. After a year they are still getting "fuzz". Heck my car had a beard on the front bumper and I had to remove the layshaft for cleaning. The rear axles were covered after every round, seams as though they got a bad batch. I would be calling CRC out to take a look unless the stuff was given to them. We run less cars at Fastlane and have way more grip after a Sunday with 1/12th and WGT cars.

While I have limited experience with foam and carpet usually less roll is better. Leaning over (softer) doesn't seem to generate grip and makes the car fell very lazy.

Try shortening your front link. It may or may not decrease you mid corner bite on foam but it will improve response considerably and on a tight track like most carpet tracks are you should be a bit quicker too.

Thanks Dragon,
I run Mike Haynes IIC rubber tire setup and Jaco greens. I currently have the front inner link @ short upper location and 1mm spacer under outside link on hub. It increases initial steering response.

I am suffering from severe on power push and I'm down to 2* rear toe but still not helping enough. Thought about reversing the .5* rear hub to take out more is that possible?
