jdawg. Is the rear lockout coming out soon, or is it something we will have to wait months for? I can see some potential with the CC. It just needs a few tweaks. |

I tested it and approved it several months ago. I will check and see when it is due to come in and let you know. J |

new video...o-rings in front hubs work great. The rear axle is still stalling out. Also, this run was done with 1 cheapo rc18 1100mah pack. I also tried it with a 3s lipo but the rear motor still stall's. I almost think the problem is my rear motor not true "clod stall" http://www.hobbyzip.com/videos/408/d...f-climber.html Rear Lockout installed: My redneck battery shorting: |

Mine seems to run just fine. The only gripe I have is the slop in the rear steer. I'll lockout the rear and ditch the rear servo as soon as the parts become available. I'm running mine with 2 hitec 645MG servos, Mamba 25 ESC, Dimension Engineering Park BEC, and 2 cell Lipo. I had to rewire the motors to get everything to work, but everything works fine now and the speed seems comparible to my Axial Scorpion. I'll try to get out on the rocks tomorrow for the real test. |

Ok.. I just installed a homemade rear lockout (like jetboat) and now its much more pleasant to drive. I'll try to get some vids up soon. |

I just ran mine on some big rocks at the local state park. I'm also noticing considerable stall of the rear axle on difficult climbs and tight spots. I took off the stock wheels/tires and replaced them with some Proline Eight shooters and Flat Irons (4 oz lead in each). I'm still running a 2 cell 1500 lipo. I wonder if a 3 cell lipo would be better? |

OK Jetboat... I'm beginning to think after watching those 2 videos, that your driving is whats making the truck look so bad Just kidding Big improvement between last video and this one in the way it works! |

Ditto... The first video really made me wonder, but the second one really impressed me. I've always been skeptical of these things since I heard "two 380 motors". But the second video makes it look much more capable. |

I think if he was to place the tires on the rock as opposed to the front diff the thing could crawl further. But the second video does show vehicle improvement.

I knew there would be comments on my driving!! Its not easy to film and drive at the same time while swatting mosquitos. I have tried single stick pack, 2s lipo, 3s lipo, dual stick packs and dual 2s lipo.... all had the same result. I am going to try adding about 8" of wire to the rear motor. That should even out the amp load. (or maybe its the front motor I need to do that to....) you'll also notice in the most recent pics that I pulled the bumpers off the front and rear axle.... really helps. |

Jet One of the first things I did was pull the bumpers. I'm sure most of you know this but pull one of the batts out of the chassis and velcro it onto the steering servo. We also have a carbon fiber battery/servo mount plate option part you can use. As far as bodies, I have used the J Concepts rock steady http://www3.towerhobbies.com/cgi-bin...?&I=LXUUB0&P=7 and the Proline rockstar http://www3.towerhobbies.com/cgi-bin...&I=LXTYL2&P=ML for a scale look the RJ Speed body is good http://www3.towerhobbies.com/cgi-bin...&I=LXUYX9&P=ML J |

I had found some gear reduction units that look like gd-600's, but fit a 380 size can on ebay a year or so ago, think something like that could help?

graupner and several others make 380 reductions...Im just not sure there is room. What we are fighting with is typical clod stall.... a way around it is to use 2 esc but I dont wnat to do that

I'd like to add some weight to the stock wheels. I tried to get the tires off the wheels, but I haven't had any luck. Those things are really glued on. I've been running debonder around the rims for the last hour. Still can't get them to budge.
