M06 Handling

If I can get an M04 to brake in a straight line I will be delighted, see you at the track.

Duane.

Andy,

Please tell me the advantages of the M04 comparing with the M06, besides that we already have it?!

Understeer is good for that thing to start with.
Most important thing is that the rear end doesn't want to overtake the front end!
You can get more steer with:
- Different tire combination. Will test the Shimizu's Friday.
- Traction compound.
- Increase track width at the rear hex or make the front more narrow
- Stabilizer at the rear
- Softer shocks at the front


Duane,

You hardly need any brake with the generated speed of the car.
Just let go of the throttle in time! We re on a track without pedestrians :-)
Or reduced the brake force on the transmitter or ESC (if the functionality is there)

Ed, as far as I can tell, the 06 is a lot more stable. But it does have the same gearing as the 03 so lose that advantage. My motivation is that it is newer and I am able to use my 'square' hard pack lipos in it.

Otherwise, it's new

OT.. for those who are having trouble with servo savers, i will be ordering kimbrough servo savers soon.. lemme know if you guys are interested. i have them on my mini and ff and they are great with steering response.

Square lipo pack, that's a very good reason.
Even the rounded one fits in the chassis only after getting introduced with Dremel.

The car is lighter now. So creativity is required to add some weight at the right places.
Then again, it's not a rock crawler, so don't overdo it!

Kimbrough servo saver is good.
However, you need to mention the spline type for the servo you're using.
I don't believe it comes with an adapter to support the 23, 24, and 25 splines.
The Tamiya high torque ones are working well!

@ ed, the kimbrough savers have 3 different splines for different servos

Hi,
I will take two kimborough's if anyone is order them ?

Also I have active yaw control working on the throttle channel of my M04. Going to take it outside for a test in a few minutes. There will still be a lot to do, I need to add active counter steer on the steering channel and mix the steering input to reduce the level of active control as the steering input increases - otherwise the car will just want to go straight.

Duane.

Initial Results = Wow !

Ok, its not finished but with just active control on the throttle channel, the car is a lot more stable and very powerslidey (new word ?)

The software doesn't intervene until it detects the car stepping out so it holds a moderate angle and you can hold full throttle with full lock without spinning out.

Off to implement counter steer now.

Duane

Spoke too soon :-(

Duane

@Ian, I'll need 3 sets of those Kimboroughs please. Thanks!

@Duane, where did you test your system?

Ian, sign me up for 2 of these servo savers too please..... are these ones that the mini's can use as well? Just curious, the tourers use a single ball setup and the mini's dual...I suppose that in a tourer you can just use one and offset the servo saver?....

Duane, I admire your perseverance on your unit, but you would probably have a lot more fun down at the track racing ...no seriously, I know when something like this is part of an experiment, and an effort to be creative, there is no end to the research. Look forward to seeing this beast when you have got it running like it was intended.

I was well surprised at the handling of the M04 at the track, mine was pretty standard format apart from the lowered stance, oil shocks and Shimizu tires. It handles really well! And is good fun to drive. The FWD's are just plain sailing and are great for racing, but the RWD is a really nice challenge. When they get going the certainly CAN run with the FWD's.

OT: 2 for Duane, 2 Andy, 3 Lance, 2 Ian

Hi,

I was testing outside in the street, there isn't much traction so its ideal for testing.

I found the problem in the end, my servo kinks to the left when the motor is under heavy load. Now I need to figure out whether its a software, hardware, power or interference problem.

It might sound crazy, but a project that has a lot of problems to overcome is ten times more enjoyable than one that just works, infact its always a bit of a disappointment when there are no problems left to solve.

The 22,000 people that have visited my blog would seem to agree ;-)

Duane.

Looking forward for the next run with the minis.
It was great!

Hi,
Whats working on the m04s ? M-Grips, S-Grips or spice and the like ?

Andy,
You must have lots of spice tyres from the m03's do they not work, are the shizumus that much better ?

Duane.

The formula before was A type slicks at the rear and M or S grip at the front.
Tried 60 size Shimizu s, soft at the rear and hard front.
Car was planted and doesn t even stepping out, very nice to drive.
No problem running along with those fwd s with the M04!

Yep, Shimizu's are the sh....business.

I have always held the RIDE 3035's as the best grip for a mini (FWD) in the atrocious conditions we used to run in, the negative part of them has been that they are small diameter, and did not give good top speed.
I am not sure how the shimizu's will work on the FWD's but my suspicion is that they mght induce some traction rolling. The sides are very 'sharp' where as the RIDE's were a nice curve which reduced rolling.

The Shimizu's are definately wearing evenly on the rear, but are wearing on the outside edge on the fronts.
If I were to try the Shimizus on an FWD, I would certainly go for a harder compound, which is what I will get for the front of my M04.

Good tires, and same prices as the RIDES, approx US$15 a pair, before shipping.

Hi Andy,

You in tomorrow ? I could do with seeing a more or less sorted M04 to see what I should be aiming for with mine.

I want to give the electronics at least a chance to work, right now my m04 is pretty bad.

Duane

Duane,

No, I am out and about tomorrow most of the day, will only be home in the evening. I reckon my M04 handles worse on the dusty road outside my house, than yours with all its gizmo's. The only place you would get to see a M04 dialled in, is at the track.... it's cleaned regularly, sugar-watered and we use a little traction compound....chalk and cheese when compared to ranches speedway...
