The plus 2mm (black) hubs help alot at least with the stock losi rims. haven't tried any others yet. They still rub just a little on the back of the arm but not much.

The 2mm hubs solve the problem with the losi, proling, AKA(didn't need it to begin with) and old school GRP 0 offset wheels. These are all of the wheels I have tested so far. A tad bit of dremmel work will stop them from rubbing the arm and cracking. POroblem with cracking was when you hit a tube or something it would slam the wheel past full lock and smash it into the arm. Thats how the wheels were cracking.

I Just got my 2.0 today and working on the set up and fixes. Had a question on the plus 2mm hubs for the front though. Will they change the way the truck handles? Had anybody noticed a difference? A guy at my local track told me not to put them on for this reason.

I drive on a very tight track and the +2mm hubs do not hurt the trucks handling one bit.
I do run the front and center smart diffs though.

Haven't been able to drive mine yet so I couldn't say for sure. Even so I would have to say, yes they will change how the truck handles. I doubt it's a big change. It could also be a change for the better, idk. It would be better to incorporate some type of steering stop modification at the hub. Still planning on having another look at mine to see what I can figure out for steering stops, but for now the 2mm hubs are an option to prevent wheel damage.

Have a look at yours and let's see what you can come up with for a fix.

the plus 2's actually seemed to help my trucks handling, it turns alot better now that i can get full throw

+1. They do change the handling, but in a positive way. Being able to get full steering throw really can make a difference. It will turn harder and NOT rip up the webbing in your wheels from grinding.

Thanks guys , I'm gonna go ahead and try some, I'm also going to order the alluminum servo arm, And I have some Avid bearings on hand for the rear bearing issue for now. Hopefully mine will last a little bit. But from what I've read on hear they dont. I've got the longer screws where required , Anything else I should put on my order from A-main without breaking the bank too much. I know ....what kind of question is that??? It never ends.

1.0 saver spring to go along with that alum top.

I'm still having bearing issues with Avids. Three 7 minute qual's & a 30 minute main and all of the outer bearings were gritty, inners were perfect. I'm also running aluminum front spindles. My AKA wheels had several cracks in them but the Losi wheels didn't. I'm also going to try the +2mm hexes and see what happens.
Overall, this truck is awesome!

Is 2mm needed or are the Xray 1mm ones enough. (I hope the latter since that is what I have installed but not run yet)

How did it look to you? Does it still rub on the front and rear of the front arms? Did you check it throught he full travel of the suspantion?

I know I had read that the 2.0 servo/reciever/battery trays were better in some way than the 1.0. The only thing that looks different to me is the throttle/brake servo will be a few mm further away from the carb when mounted and that there are already shims built into the tray at the throttle servo area. I guess my question is what makes this tray better and are you guys using the rubber spacers at either of your servos, or just hard mounting them. Thanks for any comments

you ALWAYS use the rubber eyelets for the servo's....these cars Vibrate like crazy when the motor's running and those extra vibration's are no good for servo motor's....you will need longer screw's to use them tho...also the 2.0 tray is Alot stiffer of a design which imo is needed...dispite there being a couple radio trays that are breaking out there...im thinking its more from a hard landing or extreme chassis flex.

Ya I had the rubber deals mounted on my 1.0 at both throttle and steer, with longer screws at the throttle, the only reason I questioned it was for the throttle on the 2.0 because the tray has those spacer/shims permanately on the tray, just like they were on my 1.0 rtr tray.
