Hi ! Not at all This is 5/32" aluminium sheet. I milled axle fixations at 1/8" to keep original width. The next step is to reduce aluminium chassis weight |

Hi! More news It's done, I have installed 4 voodoos with double deuce CI foam, soft at front and medium at rear Another change: shocks The berg are too heavy, so I put 3racing I recycle old springs, shorter and more flexible. I find them very progressive now And I turned delrin hubs to reduce axle and wheels (i don't know the right word, sorry ) width by turning the wheels I am really surprise by the delrin toughness The battery pack moves on front axle, with homemade( as you can see) aluminium protection So I can remove weights on front wheels and earn 180g to be at 60/40 repartition The next step is to be on podium at next (friendly) competition |

Really nice build! Been waiting for someone to really dive into the V3! What's your skid height, that's some serious clearance! |

Hi Some news, because a crawler is never finished I made new axle: with new supports Waouh! I changed upper link support by 2 aluminium parts After a run where I loose spring support, I turn 2 aluminium parts I will never lose them I'm working on new universal joint The right wheel with new universal joint and left wheel with original part And I can't get more, because tire touches gear box I'm really satisfied because I find this is really "the" problem of berg V3. This is a prototype and I need to optimize it, but it's a good thing I began to turn pinions to earn weight, but it's not finished. I can do better New front wheels too, made in aluminium, with delrin hubs (8mm): After a crawler meeting at "La couronne" in south of France (a wonderful rocks beach, with a phenomenal grip), the PACA (www.rccrawler-france.com: Forum Dedié aux Crawler et Scales Radio-Commandé en France, Conseils, Astuces pour Créations Chassis Complet, News, Galeries Photos, Liens Utiles • Afficher le sujet - P.A.C.A!!!!!!!!!!!!!!!!!) with many sponsors ( a big big thank to them) I decided to shave a part of front tires to get better stearing. Next step is unpackage fxr, Rx and minimize wires weight, without forget universal joints and pinions |

Hi Thank you So the next step is to finish to turn gear box pinions. I leaved 1mm of metal against 3.5mm before. I could earn more but I don't want order new pinions set during a run And I milled rear wheels (1.5g earned by wheel ) but I find they have better look I need to lighten more the rear axle if I want stay under 2kg. I still work |

Many people will be happy It's a good deal, because you don't loose CrV protection. Do you know how many the set weights ? But, I prefer homemade, when I can |

Hi Some news, after a long time So first, I changed berg rods end by some traxxas and the difference is really big I modified front hubs. They are 8mm more and now I have 290 mm of axle width I made the last version of my CVD ( miss the second, but it's many work ) And i turn the rear wheels to have 275 mm axle width I modified steering to turn more, without move servo I put a brass ring between screw and plate |

Hi Last finishes before the "BIG", our crawler and scale meeting . First, I glued every screw of my berg (I don't know why, but berg screws loosens) After, I milled and polished the front axle where is striped( where is striped, where is touching) And I changed bottom big screws by some flat (I haven't picture, but I took savox servo screws ) I hope that will be good |

Hi New internal rings P13 (dedicated to his inventor) ultra light version to exchange the beadlock inernal ring. 25mm width for the rear I made some rings for voodoo, but too for HB, really more efficiently on wet terrain. (each year, we have one raining day for the BIG ) 17mm width for the front and the wheel complete, with hub and steel screws It's really easy to turn. It's just disgusting And It's done. The Berg goes under 2 kg A friend has a CNC milling and cut my chassis replacement in carbon(2.2mm) and 15g earned Now, I had to be at the machine level, that will be hard |
