You might want to get more than a foot unless your selling it by the inch.

I haven't seen many RB6's with a Speed Passion Reventon Pro mounted. I thought the switch maybe impossible to get to but once I wired up it's fairly easy. Programming is done through the RX Wire. I could had easily cut the tabs off the mount and moved it forward but I wanted to build the car without modification, plus I can easily move the battery back if I move the ESC's Cap.

I really like car's wiring management in the side pods. Makes for a clean install without much effort.

how do you mount the receiver strap to the battery box. Mine is mounted to the rear bulkhead and I would rather use your config.

I used some other posts they included in the kit that allow for a screw to be used, then added a 2 mm spacer on top of them to space up the receiver mount and and screwed the receiver mount to the posts. I then cut the battery strap to the length I wanted.

Did you guys see that Yaiba is releasing wide RM suspension holders? I wonder what the price will be. kinda hoping it is closer to strc than Kyosho, lol prices

According to the Yaiba site

Both hangers = 2400 jyp ~ $25 - $30 USD for both. Just a guess, but a nice option to the Kyosho holders at $50+
For reference B4 hubs = 2900 jyp = $32 USD at tresray

I am looking for more forward bite. Loads of side bite but need some more forward traction. Do you guys have any suggestions for changes that may help increase this. I'm running close to the tebo mm setup.

It is good after the layout traction comes up. yesterday was the first day on the fresh new track. Everybody was battling traction, even rm guys . Our new layout has great corners that are fast with mm. And the winner of the a-main was mm last ight too.

I have used Tekin RS & RS Pro, Viper VTX10, Orion R10 Pro and now the Reventon Pro in recent years. The Orion R10 Pro and Reventon Pro are very close in performance and both can be made very smooth on the throttle, but I think the MOD2 software on the Reventon has a bit better brake feel, IMO. The other two listed I won't consider again for Off-road 2wd buggy.
