I just drilled the holes and tapped it with a stock bolt and some wd40. Worked like a champ.

The work has begun. I am taking my time with this to hopefully avoid problems.

It is pretty odd to have a failure like this and not see anything broken and have it go back together and work for a short period again. With the power we put through these things, stuff usually either works or its broken.
Yes, disassembled all the way down to taking out the rubber o-rings.

It's kind of why we are scratching our heads here. It doesn't seem like there is anything in the box that could 'come loose' unless it plain broke.

What's a good diff oil setup for bashing around in the grass and loose dirt and bark dust?

45 tooth Spur/17t pinion on 4s batteries and a Hobbywing 2250 motor / SCT Pro esc.

Right now we have the 5,5,5 setup from the kit. When I switched to the 17t pinion I can pull wheelies but there's a method to it. That's fine.

What I want is better hookup, but not so much that I will pull wheelies if I pin it from any speed. I want to keep that front end planted.... and, a bit of addition to the on power steering would be nice too!

With that much power only way keeping front wheels on the ground add brick to front of car.

It's really not that bad right now, and was impossible on the 15t pinion.

I read thicker center diff fluid keeps the front wheels planted, but then others said thicker fluid gives the ability for instant wheelies.

Built the front diffs and they are butter. I have never seen diffs this smooth, very impressed.I am almost through kit B, no hurry. There is a race in two weeks that would be nice to run this in. 8th buggy is huge there, at least two mains.

It took me 7 hours, taking my time and using the included tools in the kit so you should be able to blow through it.

Default Converting a 3.0 to 4.0

Has anyone successfully converted a 3.0 to a 4.0? My 3.0 is in good condition and I would rather buy the updated parts piece by piece over time then spent over $500 on a new kit. I already coverted the shocks. Besides the chassis and the motor mounts what else is involved? Thanks

0 and 4.4 degree center plates, new body, new battery tray, new casters and spindles, new hubs, new towers, new stub axles with boots, new adjustable rear hinge pins, over 360-400 plus to update the car. Might as well sell the 3.0 and get a new fresh kit.

I personally would just do the chassis and motor/center diff parts. That's the main thing I would like to have.
