For the pipe side Velcro, I put a couple drops of thick CA glue on the back and it solves that problem

Does the velcro stick to the body and plastic mudguards real good? Is de-natured alchohol cleaning good enough for adhesion, or is there something else i should do?

The Velcro generally sticks well to the guards and the body, except for the pipe side due to the heat. Honestly, I've never bothered to clean anything before applying the Velcro, but it won't hurt. As far as the effects of using the Velcro or not, I don't run without it for a couple reasons. First, it does keep the dust and dirt down as well as keeping large rocks and pebbles out. Second, I believe it can improve handling both on the track and in the air by keeping the body tight to the buggy and minimizing air entering the body from below causing a parachute type effect....just my theory on this one

I've never ran the velcro, but will give it a try based on the feedback. Would love to cut down on the dirt inside the car...

Hey guys

Just thought I would give some feed back from the race meeting today
Did not have a great qualifying I started 10th in the amain and ended up 4th overall. It is my first race with the KCar it was really solid the tack was very loose off line and bumpy in certain areas.

My nova was really economical helping me get so far up in the main

Proud to be part of the Red Army

Car feels really planted, and easy to drive, but just looking for more corner speed and trying to get out of corners faster.

Here is a video when a friend of mine let me borrow his Ninja B02. I usually run Nova engines. This was the first tank I ran, so in the first few minutes I am trying to get used to the completely different power band. Any advice, driving or setup wise would be appreciated.

Your driving looks pretty good in the video. The camera man's shooting ability needs some work! Your front shock oil seems too thick... especially in temps nearing 55 degrees and with orange springs. I don't even know how it rebounds! From my cold weather experimenting this time of year (granted not at Rev) I think you may want to try 37.5 (TLR). I think your diffs are too thick as well. Try 5/5/3. Also, bias your brakes for more rear braking and less front braking. Not so much that your rear tires lock as soon as you touch the trigger. The idea is to have less front braking so the front tires can roll sorta freely thereby keeping their traction and keeping your turn radius tight. Too much front brake can make the car go wider. Adding in more brake to the rear makes the car have a tendancy to start to spin. If you get it right, it won't spin. It'll only start to spin and then stay kicked out to the side. Jumping on the gas after it starts to spin, but before it gets stuck kicked out to the side, will keep the rotation going. The front tires will be hooked and the rear tires will be pivoting around them and you can drive out of it on power.

Has anyone noticed that the stock TKI3 brake disks are warped and that makes the car not stop smoothly at all? I say this because I noticed my car was pulsating to a stop. The brakes seemed grabby. I put in new Kyosho brake disks and pads and the problem was still there. The vented rotors as well. I resurfaced the second set of stock brake disks by hand on a flat grinding stone and the problem finally went away. A fellow racer at my track told me he had the same issue with his Kyosho. Anyone? And what is the remedy beside having to grind them by hand for a half hour on each side?

Yes, same here. We had traveled to a kbrl race in Tucson and I was going over my car in the hotel the night before race day. Couldn't figure out why my brakes were sticking. It wound up being warped stock discs. Went with the vented and haven't had the issue arise yet

I finally had the chance to get my MP9 out to a nice indoor track. Moist smooth clay and fairly technical. My current setup can be viewed here Baseline TKI3 Setup. I had very little steering off power and on power which leads me to believe it was a tire problem. Hard throttle would spin the back end around on command but coasting into a corner at any normal entry speed left me with almost no steering. My first step will be to try different tires, does anyone have any other suggestions? I'm more concerned with off power steering at this point. I will also make some geometry changes to get closer to CWS (Cody's Worlds Setup) namely raising the front roll center and shortening my rear camber links.

Thanks in advance for your suggestions.
