M03.1 includes: low profile servo(32g), lightweight blitz c30 (0.5mm) body(47g), losi lcd drives, ofna diff lock lube in the diff, brushed motor red dot(legal), TP battery 3200(208g).... Total weight is 1120g or so ... No way I am putting weight in that car : too expensive.... Tamiya should drop its weight limit to 1180g or less... Brushless??? Not in this funster class for me...
Now in the summer heat I mostly run my Ntc3 against those new Xray nt1 2015, mugen mtx6, etc, and I do fairly well if I don't hit too much... Lots of guys are surprised !

Just to clarify - National Rugby League is much better than Aussie Rules (where they don't even have to catch the ball. They drop it and play on...). Rugby League - 40minutes per half = 80minutes total. Less any time the referee stops it for injuries or other incidents he wants to.

Well, he'd better put on all his pads.
Great conversation going with Bonecrusher and Granpa. Ones of the best I've seen in a very long time. Ivan's car/driver balance leans towards driver. The car is not as scienced out as some, but is nicely balanced and fast but, if I were driving it, it would lose.
Bert...oh Bert. Just pops in, says something ridiculous then disappears, like a fart in the wind. Fun fact: He's the only other person I've ever blocked.

Speaking of kids (off topic), my older kid handed my butt to me just now doing a quick lap around the lake on kick scooters. Where do they get all that energy? 
Of course I am 4x his age, but still... 1.2 miles, just under 6min. There is uphill. I hate uphill. I should do the lap in the opposite direction.
I put in an order for the Tamiya steering link set today for my V2. I'm excited.

You were dead on when you understood that on low grip asphalt you run softer------springs shock oils etc. Matter of weight transfer. Please forgive me for this------given the same coefficient of friction and surface area, grip depends on weight. So, yeah, your assumption is dead on cause we want to transfer weight forward on corner entry and transfer weight laterally to increase grip by shifting weight to the outside wheels. The reason the M05 is slower for the tracks I run on is that it corners too flat. A good asphalt car is leaning all over the place as it goes around the track. Squeezing out that last 0.5sec is hard cause you're balancing all kinds of things at once.
This is why you've heard me time after time advising softer set ups. I've been tooting this same horn for more years than--------. Also been on the soap box about sometimes if you want one end of the car to do something you have to work on the other end. You may have to change the grip level of the opposite end to make the problem go away. Also have been saying', if you want to understand car set up, you have to understand what happens to the weight during braking, acceleration and cornering. Once you get that part, it becomes a matter of altering suspension components to give you the desired weight on the appropriate corner or side of the car. Didn't say it was easy, but I believe that's how you need to think around the problem.
I don't know about loosening chassis screws on the M03, but admit to loosening the screws on the hoops on the 05 to get a little flex. I take them off, but the tech weenies don't like that.
Tire wear on S-Grips. Yeah you're right on the tires going away as they wear. What's interesting is that they can in some instances come off the front and be used as rear tires. I generally don't rotate tires cause in my hands they don't last long enough------because of a total lack of driver skills, I've devised a method of going around the track that's a little unique and is totally dependent on car set up. I enter corners at speeds bordering the insane and a total dependency on the car turning at that speed. Makes life exciting-----You'll hear me yelling "don't slow down" "comin' thru". Wears tires quicker than normal. It ain't pretty, but I'm having more damned fun.
Sorry, I don't talk about the M06. Too hard to get it to work

But could you explain:
- why the Losi outdrives and not use the tamiya ones?
- what thickness is the ofna diff lock lube? Is it like 500,000k thick?
- are you saving wt cause that’s what your goal is to have the lightest Mini possible? If it is, cool.
- what’s wrong with brushless? Less maintenance period.
Have you considered adding weight inside the front bumper of your M03? Might help with cornering and some kick out of the corners.

One thing I keep forgetting is that you run on asphalt so I’m assuming way more tire wear. I think Monkeyracing has mentioned in the past that the current S grips (last few years) seem to be a slightly softer compound than before and seem to wear down even faster. I guess technically that might be a good thing cause the tires maybe a tad softer but the bad thing is a bigger dent in the wallet.
No problem Granpa, but would love to hear any other takers on the M06 vs M03/M05 competitiveness comparisons.

Great summary Granpa. It’s funny how even though you’ve said the same things over and over again and I’ve probably read the same thing from you and others in the past over and over again but it doesn’t really make sense until one progresses thru a learning curve and then little light bulbs go on with moments of enlightenment. Understanding now however just leads on asking more questions that I don’t know the answer to.

Thank you. Appreciate that. yeah, none of us hear stuff until we're ready to hear it. I see it at the track when I'm trying to explain why something is happening to someones car and why we're changing certain things. You can sort of see it in their eyes.
Actually, I apologize for the M06 comment. Some of the best guys I know have worked on that chassis and have never made it competitive. We've bench raced that car a lot and the consensus is that it is a better carpet car than asphalt. I tend to, whenever I see one, make the sign of the cross and walk away as rapidly as possible. Danny Eggar, our current TCS Mini Champ, is playing with his. If anyone can figure out how to make it go, he can. He's making some progress, but the car is tough to get balanced for all the corners
Hope this was more informative.

Can a damaged and untrue rim cause a car to not track straight?
I'm having a terrible time getting my basher mini to track straight. Sometimes it does and sometimes it doesn't.
It is set up to be mechanically square and at slow speeds it certainly does run straight. But at higher speeds it starts to turn. I have it set up with the 3racing steering and hubs, and the shocks are even left and right.
Using trim on the transmitter doesnt help and only makes the car track more in whatever direction I set it. If I increase the exponential on the Tx the tracking issue is exaggerated.
Cheers

Does anyone have trouble with the Tamiya Mini Cooper Racing body not sitting square on the M05 chassis. I find that one of the rear wheel arches always rub, no matter how I mount it on the chassis. I've got a feeling its caused by the the leads coming out of the battery pushing the body to one side.
Any tips or tricks to make it sit right?
