SBR 2.0 must do mod !

[3x9rtse]

I have driven my SBR 2.0 a couple times now , and can see what people are saying about the rear cage flex on it . I can see in the videos when it lands the rear back of the cage flexes down so much that it hit s the ground ( the spare tires ) and rebounds the back of the truck upward . I can't take the credit for this easy quick inexpensive improvement , Earl Moorhead is the vid I watched .
I drove it again tonight and what a difference , it's pretty much made the back of the truck solid looking .

Nice job. Earl M is very creative . Nice tip. I like his vids. He is a serious RC'er and comes with a lot of experience. His strength is Speed running I feel.

I found his vid where he realizes how much flex there is was kind of funny. He was almost speechless in the vid and added some written comments like "This is horrible" comments in the editing.

It turns out he found quite a solid fix for this problem. RC cars tinkering at it finest! It sort of makes you wonder how Losi could have missed that flaw and given the GO for production.

Hopefully Losi is watching. I have some ⅛ aluminum I’m going to tackle that on mine this weekend.

Have you driven it yet ?

Well. No. Mine is taken apart at the moment. Waiting in the correct parts. Hobby shop gave me a bunch of stuff losi hoppups for a baja Rey well it’s for the most part all different.

I reduced the flex by about half with zip ties. Made a short video.

Cool but there are relatively cheap side plates that are made of heavy plastic that work great. I put a set on mine.

Only got the truck yesterday. Printed a side plate from Thingiverse but didn't install it. The metal solution up top kind probably makes the plastic around it to break, I think . After all the forces on impact have to go somewhere...

• Just changed fluid in rear diff to mix of 500k and 20 Million.
• Stronger springs from "Schwaben-Tec".
• Lower end of rear shocks going back one hole. (Had a look at full size Desert Racers. The lower spring position is closer to the rear wheel than that of the SBR. Seems that modification did the trick for "German RC Playground" too.)
• Perhaps moving top and bottom shock position back one hole.
• Might go to a lot thicker shock oil.
• All that should stop it from rolling over all the time.

Plus Silicon (instead fo shoo goo) and tape in fender areas of body.
Have not driven it yet. Buddies SBR just kept rolling over all the time and that prevented me from buying it.
