I sold my mp9e to get the cobra be 2.0 because I liked the layout. I built it to spec as per book , you drop the car on the table from 5 inches and the chassis slaps the table. I went to 40wt oil same thing. I ordered 8 hole pistons and went to 45 wt same thing. does anyone know whats going on with this. I feel it should work as default from book but this wouldn't work in the yard. please advise before I list it on ebay , thanks Rick frustrated

Whats your droop set to? Mine did that until I measured it from the center of the top screw to the center of the lower shock bolt, now I can drop it from just over a foot and it doesn't slap.

you may have something there. I set it to 98mm measuring middle to top of mount as per book. that measures 95mm ur way. I will lengthen my droop and see what that does. that's a lot I appriciate the help! Rick

Im using the new Csi blue pistons at the moment. But before I had drilled my own 8x1.3 pistons and used losi 40wt front and losi 30wt rear everything else stock settings, worked really well.

Can anyone tell me what FTW body fits this buggy best?

Whats the smallest pinion you can run on this? I have one with the RTR chassis (cheapy) and I can't fit anything under a 16 with a 46 spur using the Dragon rtr motor, it's as if the motor hits the bottom of the chassis as there is no recessed area

If you can't mill out the chassis under the motor then maybe raise the motor/diff mount up a little? I believe a 48 spur will fit also, 46 spur to 48 is just under 1 pinion tooth.

Yeah that may be an option, did not have a good day with it today, Motor kept coming loose and sliding away from the spur, no matter how hard I cranked the screw down (even stripped out a mounting block and the 2nd one did the same) then when I think I had that sorted to pinion came loose, and then the rear diff imploded.

Buggy 1, Nexxus 0

Been trying to get close to -1 front toe out, don't have a setup station or anything. If anyone does could they measure the center to center like they do in the manual for -1 degree toe out. Thanks.

can anyone tell me were you can get carbon mud gaurds for the 811e please ive looked every were

Does someone who has the Cobra Sport, recommend it? or the RTR?

I have the RTR with the 2.0 upgrade on it, bought it off a guy here on RCTECH. Still has the RTR electronics in it. When driven well (by my son) it hangs with just about anything on the track. When no driven well (by me) I can attest to its toughness.

I can see the advantage of better electronics, but so far we are competitive as the buggy is currently set up.

In short, very happy with the RTR version.

finally i bought used Cobra BE 2.0, what springs FR & RR has the kit by default?
are V2?
what parts should I consider to have...?

thanks for your advise...!

Comes with blue front and red rear. I have been running mine for 3 months and don't even carry any spares with me and the car is bone stock. Not a problem so far and it runs awesome.
