yeah you should be good to go. The aluminum hinge pin holders are needed as well, get the strc ones if you want regular width or kyosho for wider. If you break your steering rack just order the exotek one.

i have not needed the alum holders to date. the new RB6 stock ones are beefed up i'm not the best driver. i haven't seen one break locally out of the 4/5 we have running.

The only thing is I'm worried about is my viper vtx10 not fitting with the caps on the esc. I mean its brand new never been in a car yet and viper says no warranty if they are removed or changed

there is enough room to only have the esc partially under the rear bulk head/ tower, my R10 is only halfway under it. there is plenty of room.

Do I use the RF block and the narrow rear rear part? The narrow rear rear block is also less beefy and on the diagram it is greyed out indicating its not for this kit???

Someone please explain and maybe even tell me which parts in the diagram I should use.
Thx
RF block goes with the narrow block and RF2 goes with the wider block. As long as the front block says "RF" and the rear block is the shorter or narrower of the two you're good to go.

I hope you're not running your blocks based on thickness or "beefierness" are you?

The only thing I've broke on this car was the rear suspension block. This was a result of my rear tire hitting a concrete well that I shouldn't have hit at full speed. This is the only thing I've broken on my RB6 so far. You are securing a plastic block to a metal chassis, the plastic is going to give most likely every time. I'm running the gunmetal aluminum ones from the RB5 which are the same, problem solved. My SETUP calls for the Aluminum RF and Aluminum narrow block.

Part No. UMW512GM and UMW511GM

I read often that people "hear" that the rack breaks. There's about 15 people running RB6's at my local track and I haven't seen ONE person break it. Maybe it's different layouts and skill sets that factor in...

Default New layout...

I thought I would try some new stuff for the last race of the year...new electronics layout and shortie as well as some mods I picked up from here. I also used some titanium that I had from other cars and my RB6 with this setup weights 1595gr...not bad

And yes the esc WILL fit under the rear tower in RM configuration no matter which battery layout you use (my esc is ORCA btw)...I even managed to fit the capacitor behind the esc!

This is the same case here. My wife is now driving a 6 and she isn't exactly a precision driver just yet, but she hasn't broken anything with the car box stock. The only thing I broke was a rear camber plate and that was definitely my fault clipping a tube at the end of a very high speed straight and flipping 20 times right into the wall. I can't believe that's the only thing that broke...
