| sorry to say but that gearbox will never work. the motor is to small the gears will snap. but it is a very nice attempt. |

| built it myself yes , built it myself , pics are of the front and rear out of a t bar aluminum piece , hubs and shafts (shortened) are from a losi 8 T , kinda hard to manufacture hubs yourself. The front axle weighs in at about 300 grams , the rear at under 200 grams , so total weight for front and rear is already 500 grams , half a kilogram , in my opinion , all the better for steep inclines and to keep the wheels firmly pressed to the ground .... |

| Instead of the shock mounts the way youve got them now,why not make side plates ,as in one peice and a link in between. Nice job though. |

| I'm going to shorten the arms a bit and move the shocks to a slightly more upright position , Im also going to put a arm in the center of the axle because the only thing keeping the axle from rotating is the shocks. trail and error but this is my first attempt , Ive already got plans to build a 6 wheel drive crawler ...hmmm |

| This build just makes me laugh. I love it. It is good to see ppl stepping outside of the box "with a handful of scraps" and building things. I see some issues but can't wait to see a vid of it completed. I just don't thing the gears are going to hold up. I would like to see that I'm wrong, though. |

| hey guys , reading your posts puts a smile on my face .... well it did run , quite nicely actually , over rocks , steep inclines , building bricks ..... until .....the first gearbox stripped and a then the 2nd one stripped ....lol , so I replaced the stipped gears with a higher ratio and i was back in action , for 2 hours I had great fun .....until ......it stopped dead and wouldn't move , well 2 x 130 mabuchi motors burnt out .....lol pity there ware no vids .... one thing that did work better than expected was the articulation , so I think ive got that nailed for now. so Ive stretched my budget and ordered up a set of 2 x traxxas Erevo diffs , Im thinking of locking the rear and making the front " limited slip" , and 4 x Erevo drive shafts , also , (Im on a budget) , I have bought 2 x cheap electric screw drivers that have 3.6v 380 motors and planetary gearboxes spinning at 250 rpm max , this will all be installed in due course.     |
