Since you have a lot of questions, which is good by the way, the thread will always be on the first page of the off-road section. Ultimately, your questions will help Captain to amend his first post with information that isn't in it.

I would not say that about the b4. I would also state that the b4 "just works". I am looking for something very specific from the RB6, and cant wait to see if I get it. I "thing" the alum chassis and the weight down low is what makes alot of the "new" buggies nice. But most of them are missing steering or durability. The 22 jumps fantastic, lands great and goes at high speeds with great stability, it is well made and durable, but.... it is just off in the corners. Very inconsistent in the corners and it is very sensitive to traction changes. I am hoping the RB6 will be everything the 22 is and turn like a b4. So far it seems built very well, but i have not started crashing it yet, lol. I have no spare suspension holders, so it it breaks this weekend, I will need out break out the b4 or 22. No local parts support

Well...I don't think of the track I run on as being high bite but then again I don't travel as much as I want to to get experience at other tracks to feel the differences. However, I have dialed myself out once or twice only to go back to a setup that I know that worked good. For me, I like to keep my driving style the same rather than change it to the car. If I can stay consistent behind the wheel then I can feel what the change I made did to the car and not wonder if it is my driving style that caused it. This is my experience.

lol...I was being sarcastic. You can gauge my level of interest by how much I post on a thread. I barely post on the 22 thread. The is the last buggy on my current bucket list of cars to own. I seriously hope this car works the way I need it to. The 22 was good, but not what I wanted. The b4 is great, just unstable at high speed on a slightly bumpy surface. People keep saying the rb6 does everything well, so I am hoping to find that out for myself.

For avg drivers, b4 and 22 shouldn't be in the same paragraph with rb6. I've owned cougar svr, b4.1, and a dex210. Those are decent buggies. The rb6 is a great buggy! I've never had a car that was durable, crap loads of steering, and good rear traction! The rb6 may look basic, but the performance is phenomenal. I swear by this car!

This is why I'm trying to run this car in mid motor. I also run a tekno truck so I feel like this setup feels closer to driving a 4w vehicle. It is hard to switch back and forth between the two classes for me. Mid has helped

I agree the rb6 is a great car, however the b4.1/.2 are great cars as well. They don't have the build quality or the durability, but are definitely just as fast.

This is the layout I am going to try for MM, I had to cut the battery holder so I only used the side pieces to have a mount and keep the battery inline. Wiring is still rough, have to see if I like it before I rewire everything. Going to the track tonight to see how it works.

how do you like the strc hubs? I have never run their stuff, because people always say they kinda suck.

Their not actually, I think speedtech made a red batch at one point, I picked them up used on here. I have had no issues with STRC's stuff though, I use their hingepin blocks for RF on this car and my SC-R, and their front block and pin brace for the truck are solid. Their hubs do not have the oversized bearing, which isn't a huge deal.
