Which version of kat did your friend have? Reason why I ask this is because the manufacturer keeps revising the Kat with new parts. For example the pump motor is now brushless vs. Brushed. The pump is also different, almost similar in design as the 4200xl. They have also upgraded the tracks and the spinning mechanism for the body. I can also see the hydraulic cylinders are different from the past.... I don't have a kat and I'm not trying to sell you a kat. Just pointing out things I've seen.

1. Side of body badly bent. 2. Main track drive chassis bent to a difference of 25mm from front to back. 3. Track links bent and damaged. 4. Pressure relief valve missing. 5. Brushless Esc missing. 6. Nuts and bolts missing. 7. Every nut and bolt on the main Body and Turntable was loose and needed loctite. 8. Main gear drive on turntable motor loose and fell on first test, so had to pull it all apart and start again. 9. Paint job is sh^%. 10. 1 out of 3 servos to drive hydro valves stuffed. 11. Countersunk bolts for the main body assembly, but no countersinking on the holes. the main pump drive shaft also recently broke after only a few hrs use. |

on a different forum, one of the mods is a big fan of the 4200XL. I wish I knew more about the Barebones model. a lot of food for thought...

hi , I have both the 4200 and the kat, spend the extra and get the 4200.
Having said that Im seriously thinking about the bare bones and fitting 4200 internals. just my 2 cents. |

I've been REALLY looking at the 4200. and the barebones model would be good with a GOOD hydraulic setup in it as well. Has anybody picked up one of the barebones models?...
