I am getting my Graphite Plus car this evening, so look for an "official" R/C Tech review up on the main site soon. Better late than never, eh?

I would start off by tightening your rear diff, if it's too loose, this can cause your car to lose traction has it enters a turn. If that doesn't work try less antisquat in the rear. Those are the two things that I think have a major effect on a car being loose on entry.

Senna, what type of motor are running? I found with some motors that they have such a powerful magnet in them that I have to just roll off the throttle with a one-way. Otherwise I have the same problem as you do.

Hi Kraig ...

In our local championship we use the Corally Street Racer 21 turn STOCK motor. Our final overall gear ratio is usually around 4.50! We have a huge asphalt track outdoors.

I tried almost every combination of setup ... however now that I think about it ... I never adjusted the rear diff. It was always a bit loose.

I also spoke to Matt Francis and like guy (TeamRoy) on this thread, suggested that a tighter rear diff. can help. I will try to tighten a bit my rear diff. next time I go to the track hoping I solve this problem.

Apart from this problem ... the LOSI is great! We have quite a good selection of cars in Malta, TC3 Factory Team, Yokomo, X-Ray, etc. and I still manage to make some of the best lap times ... although I feel that I can still improve!

Thanks guys for your support!

Senna - you didn't list what roll center blocks you are running. You've listed 2 deg castor blocks and the 0F pivot block for 0 deg of kickup? About the diff, I wouldn't suggest making it much tighter or you'll end up magnifying the problem. Do it in small steps. A looser diff allows you to corner faster. But you have to make sure that your chassis' weight transfer is right first.

After looking at your setup, I still think you should move your rear arms all the way forward. I think you'd be surprised at how much that one little adjustment changes your car's handling. Move your front camber link in to the #2 hole. Try 60wt oil in the front and 40wt in the back. I'd also consider increasing your castor on an outdoor track.

Hi Dave ...

I use the Trinity (red) high roll centre blocks (front / rear) ... like the standard plastic ones (I think).

As regarding my rear diff, if I keep both diff. halves firm I can still turn the pulley with my thumb (with bit difficulty). Do you think it is loose?

I will try to make the adjustments you mentioned too and see the results.

Thanks again man!

Senna - with a properly built diff, you can run it quite loose without being able to turn the center pulley. I guess it depends how hard you are cranking on it. Remeber that a newly built diff can slip a bit till you break it in some. Just set it so that you can't really turn the center pulley while holding the outdrives.

Senna,
Where do you run the battery pack? Forward or back?

Just wanted to publically thank Kraig from KT Hobbies for his help at the Novak TC Champs. He "loaned" me some Losi rear hubs and dynoed a couple of motors for me that he neither built nor sold. Thanks again and "Buy from KT!"

the Graphite Plus comes with everything to build 2 diffs, but it also comes with stuff to build 1 of the diffs as a spool. So out of the box, you can have 2 diffs or 1 spool/1 diff
