Today i finally got the parts that i was waiting for. Of course it was impossible to leave them in the bags until tomorrow 😁 New chassis, slipper shaft, slipper pads, spur gear, pinion gear, center driveshaft, center driveshaft cups, a lot of new bolts, new bearings... Whole car stripped to the last bolt and rebuilded... Ran out of two bearings 5x10x4, as you can see on the picture, will replace them when they arrive... The car is now RTBA (Ready To Break Again) 😂

Funny, i had the same problem... at the end i assembled them the way you described, as it seemed more logical. They run very smooth on the table, we will see when the car is assembled... Those metal shims...on mine, there was one on the first front shock an two on the second, and no shims on the rear shocks 🤔

Uh i really didnt count them, but i know i added one on the front diff and two on the rear. It is different from diff to diff, you must really set it up individually... If it is not running straight than you have the problem on the diff bell, did you rebuild the diff? Are those four small screws tightened equally?

It is necessary to rebuild the diffs when you get the car. I was suprissed how badly it was assembled... Dissasemble, clean the old grease out and use some quality grease. I even had to order additional set of shims, as there was to much play left to right... I did some more work today, rebuilding the car, while waiting for the parts to arrive. Front end completelly rebuilded, diff regreased, gear mash readjusted and bearings replaced. All 4 shocks rebuilded with new o rings and also new shafts and pistons for the fronts...

Well i had this in my plan, but then said to myself that the plastic spur gear maybe isn't that bad... Especially because i like to have one cheap weak point in the drivetrain. At 2,7€ a piece i really don't mind changing it from time to time, but of course not everyday 😁 well, while waiting for the broken parts, i decided to do a complete strip down and cleaning. Yesterday i started with the rear end and was very happy to see that all the gears are in great condition. Will replace all the bearings and damaged bolts...

When i was ordering parts for the last damage i allready had the carbon plate in the basket, but then i realised that with carbon upper plate there is no more spur cover... As i drive mostly on gravel i think that the spur gear will quckly get damaged from the little rocks catching between the gears... Am I wrong?

those tyres look good, how much is the diameter? are they the same size as the original ones? I was very happy, as now it has been almost a week without breaking or bending anything...until today... I did quite a big jump with a very bad landing with crash... The result? -chassis broken (between the motor mount and rear diff) 🙁 -damaged spur gear -bended slipper shaft -lost plastic piece that holds the slipper bearing -damaged central driveshaft -broken spur dust cover

Hello to everyone, this is my first post here and English is really not my primary language, so please excuse me for any stupidities i write 😁 Well, about a month ago i ordered my first RC and i decided that i try with the carnage. (officially it was ordered for my son, but it is way to fast for him, so he is not allowed to drive. He is 2,5 years old 😁) First thing i learned is, that it does not deal with crashes very well. I mostly bash it around my house and it quickly gets broken. Front driveshafts are my biggest problem, as they bent very easy. I am straightening them all the time, it is easy, but i am really tired of this... Are there any stronger alternatives, or we will need to make them from better steel? Same story is with shock shafts, they bent very quickly... As i crash alot, i quickly destroyed the front bumper, tearing the plastic on the bottom where it bolts to chassis. The second one didnt last a week, so i decided to do a little reinforcment. I used 1mm alu sheet, bolted on the bottom of the chassis and to the front of the bumper. Works very well. I can make a picture if anyone is interrested... My original brushed motor had burned the brushes after putting the lipo in, so it was no brainer to put the brushless setup in. I went with cheap Turnigy trackstar waterproof system with 3520kv motor and 80A ESC. Well of course i was shocked about the speed and accelerations, but i am slowly getting used to it. I think the wheels are the worst thing on this car. They started to turn on the hexes one by one. I had new hexes in spares, but the wheel hex was allready rounded so had to do some improvisation. I permanently fixed it into the wheel, using a soldering iron. Did actually reshaped the wheel hex and kind a plastic welded them together. I did it on all four wheels and no problems after this bodge job. Only thing is that when mounting them on the shaft you must watch very carefull that it sits on the pin and that the pin doesnt fall out. Oh yes, and i use loctite now everywhere except on plastics. Dont be afraid to use loctite, but use the real stuff, not some chinese cheap stuff... I use regular loctite 243 and it holds just right. I lost a pin from the central driveshaft, for the new one i used loctite 603 and it holds in better than original... So, -are there any alternatives for front driveshafts? -do the upgraded alu shocks have any stronger shafts? -which wheels and tyres to buy, that will have better tolerances on the hex part? also the original tyres balloon to much for my opinion... -should i think about the modification to 17mm hexes?
