Well the kv1 was having track issues,,I checked the position of the gearbox on the retaining pins, made sure the shaft wasn't bent and found what I thought was excessive play in the final drive. Swapped out both gearboxes with the ones I had spare and it still throws the track. I have swapped the sprockets around and it makes no difference, the left track still skips off the sprocket. Does anyone have any ideas what I may have missed?

Both my KVs had the de-tracking issues and it was solved with this method. Other people that have tried it and have also had great success. It is simple, very cheap, effective and does not interfere with the tanks operations.
I do recommend adding some grease to both sides of the washer(s) as this helps the “seat in” phase. Once seated and worn in a little the grease is not really needed any longer. I keep mine greased still, but they can run fine without it.
I have a bunch of videos of one KV running on my Instagram @ Fsttanks. Feel free to check them out and see the results and how well the tracks stay on.
First photo is of hull with no washer. Notice there is very little wear to the hull plastic. This is because the washer typically tend not to turn. It’s dirty grease I did not fully wipe off that you are mostly seeing.
Second photo is with washer installed with no grease. Notice the light wear on the washer from the sprocket turning in contact with it. This washer is SS because it is on my hardest run KV. In fact this KV is my most abused tank.
Third photo is of the grease I use when reinstalling the sprockets. I exaggerated the amount in the photo and much less can be used with nylon washers. Yes dirt will stick to the outer edge of the washer where grease is pushed out but this has NO effect on the tanks operation.
Fourth photo is of dirt adhering to the excesses grease on the outer edge of the washer. Again this dirt has no effect on the operation.

One more question to you, do you have a method of tightening those loose idler wheels these things have?Mine have wobbled since new, would also like to get a track tensioning systym for her
I went the route of of simply making the idler mount more solidly attached to the hull with screws vs the simple pressure fit HL uses. The pressure fix does work itself loose and adds to the idler wheel moving around more then it should.
I use metal idler wheels and with the more solid hull mount they are not any more loose then my other tanks and have not caused any issues since the modification to the idler mounts were made.

I keep my idler wheel fittings grease/oiled and have not noticed any wear worth noting.
