I did mine but it toutches the graphite stabiliser part on the side? Did anyone have similar problems? Thanks Acid I have the nova conical rubbing againts the center belt at 710 but not sure if 720 has this problem. Maybe you can feedback. |

Who has the 1000mah packs for the 720? |
We make 1000mah batteries for 710&720. It's 19 usd excluding shipping. We use Gp batteries.

Thanks for all the info, Qlone, you were right :nod: ... all I had to do was to bring the pulley closer to the car... play now is 0mm. Before I figured this out, I had about 3.5mm of play... Sometimes it helps just to re-check things :nod: Thanks Julius, I am running a RB with a conical.. have the same problem... will need to shave a little of the graphite part... Thanks Acid |
acid, car looks great.
anyway, dude you can run that 750 for a long main. who says you cant? i used to run a whole day of club racing with my 710's 750mah. 3 quals and 45 minute main, without having to charge.. :nod: |

I am running the Serpent one and it lasts all day.... I re-charge before the final though, for safety :nod: Acid |
Setup
Hey Guys
One more question from my side in terms of setup... Is it safe to assume that the more bends a track has (especially 90 and 180 degrees) the higher your roll center settings should be? I know this is not a rule that is cast in stone but it does make sense to me... eg. If you on a track where the a good time is 23-24s, track has more than 10 bends, then you should have higher roll center settings? Any thoughts? Acid |

http://cgi.ebay.com/NEW-SANYO-RX-100...QQcmdZViewItem Most makers have moved off shore but Sanyo continues to make their cells in Japan. I prefer Sanyo due to consistency. A pack performs no better than it's worst cell so manufacturing consistency is critical. |

The runtime of the batteries also depends on the servo types one is running. A high power digital servo is rather power hungry and will drain a pack much sooner than a simple analog one.
When I ran my car using two simple analog servos I could easily run it for a day on a single charge. Now I have two (stronger) digital ones and almost make it, so I recharge once during the day... |

I shaved about 1mm of the stifner at one point only. The hearder fits perfectly. Snug fit with about 1.5mm space between the parts. It is too close to the screw hole to shave off anymore. I will take off 1mm of the header just get a little more clearance as this will help with accidents :nod: Acid |
