How do you know it's residue and not just being really clean?
I use lint rollers on all my tires to clean them, though I also use water on a rag almost as often. I've never noticed anything other than the original tire compound after cleaning them with a lint roller. They are exceptionally grippy at that point, because there's no dust or dirt or grime from whatever track it last rolled on, but I've never seen anything other than tire after cleaning.
Just for shiggles, last night I taped a few tires using some Duck brand masking tape as well as blue painters tape by 3M. I then rolled the tires across a tissue figuring if there was any residue a tissue would surely stick to the tires...it didn't.
And to add to the mayhem, I even used black electrical tape which produced the same results.
I think what you are seeing Dean is just really clean tires as MrFlippant mentioned.
2 laps in each direction... At low speeds to check for problems...
Found some Problems....
If you remember some places of my track... Well the bit slipped and it went clear through the track. And other places well sometimes the slot is not perfectly smooth..
So here goes.
#69 the front of the guide rubs in a couple of places, the nose hops.
#129 This car is MUCH better than last year.
#17 This car stops dead in 2 places one direction, hops the other direction Kinda like what happened when my Fly Truck from the FTPR ran on last years track.
The fix is simple nail clippers and round over the front corner of the guide. I've never seen this problem because it is one of the first things I do to all my cars.
When it bottoms out there is a smooth transition and the car doesn't jump or flat out stop as in the case of the #17
I have clippers awaiting, surgery is quick and painless. I doubt performance will suffer.
But I want a ruling from the SLOP Brain Trust and the owners of cars #69 and #17 before surgery commences.
I wish I could have run the GNATSTER as the poor thing couldn't even do a lap on last years track. If it is OK, send it my way before sending it home.
I will cover shipping from my place to home.
Dean is the problem where the bit went all the way through? If it is Dean you can fix it easy. Take a small screwdriver or anything with and edge and chamfer each end of the hole so it ramps up to the bottom of the routed slot.
Are you sure your routing job was at least 1/4" deep? Check and make sure it 1/4" all around the track.... if not then take something that will fit the slot all the way to the bottom and scratch out the slot so guide blades do not hit.
You do not own a Dreamel or a file to cut plastic? You can do it also with just the backside of a Xacto blade also... I would only angle ramp the front leading edge of the blade with a Xacto and call it good. You can also just sand the bottom of the guide easy. Nail cutters cut by displacement of the material and can screw it up on something thicker than a nail.....
