An advantage this car has over the Genetic is the amount of room available to mount all the electronics low to lower the CG.

Wow, that's a nice car. I like the compact layout and belt drive. Mid motor is cool too.

Kila, I can pick up the decals and instructions at the next race. I'm in the middle of cutting graphite to make my MO4 con-craption.

I am building it to experiment with weight distribution and handling of the rearwheel drive chassis. I'm working on a way to adjust caster, improve ackerman and limit bumpsteer . I really wish there were easy ways to also adjust for anti-dive and squat, but the "plastic fantastic" is the limiting factor.

What's the body worth? I had an idea for it's use, but it's not critical for my current project.

Avery, on the M04, here are some tips I found.
1. Use the stock servo saver. I tried other brands, but the length of the arm is optimzed for this geometry.

2. Invest in the alum front upright. This upright has two holes. If you use the inner one, you can get pretty good ackerman angles.

3. Place the 5mm ball above the upright and not below like the instruction states. This will make the turnbuckles do a "banzai", and eliminate almost all bumpin. You will need to shave the chassis a little to avoid rubbage. This mod alone has a tremendous impact on handling for the m04. Recommened it to corytomo too.^^

4. Ppl might think you need less weight up front... my answer is not quite. The front it too light, making it hard for the tires to maximize contact patch. You can try fiddle with softer inserts, springs, etc.

5. mod the front upper arm. When you fully compress the front arm, you will see where the upper arm binds with the Chub. shave this part. A similar thing happens in the back where the rear upright hits the body post. Shave the body post.

After messing with the M03, I have some new tuning concepts that I want to incorporate on the M04. Hopefully, I can get it the thing up and running soon. lol

Thanks Keiji,

Great tuning tips. I noticed that steering mod on Cory's car.

I'm noticing a lot of compromising was done with the MO3 and MO4 in order to use existing gear sets, screw hardware, etc. I bet Tamiya could have made a killer Mini, one that does not need shaving this and rearranging that in order to work well.

It seems most racers are tuning out bumpsteer by eliminating suspension travel. That's not my idea of good race car design. I'm really trying to find a way to tune for caster as that has a large impact on turn-in characteristics.

Oh, one more thing, YAY Sticky Cheeken V6 Thongs! LOL!

Tamiya with their mass level cars are designed more for form then function and they don't typically worry about things like bump steer. But it's amazing how well their cars can work even with such design flaws...The F201 has some of the worst bump steer I've seen on a car and that one seriously effects the car's handling. That was overcome by using a bent steering link to move the connection point from the top to the bottom of the steering knuckle and change the angle of the steering link...maybe a similar idea can be employed in this case. In the case of the F201 moving the link to the bottom essentially made the virtual steering arm parallel with the suspension arm to eliminate bump steer...given the position of the Mini linkages maybe raising the link is actually the way to go.

Yeh thanks Keiji! I did that bump steer mod and it works a lot better now.
I shoulda gotten more parts for the M04 but I stopped after the ball diff, shocks, bearings, black can, and 19t gear.
Maybe later I'll get more cool stuff!

oh just think of it as a feature not a problem lol. imho the front end could use much more camber, and if you are really creative possibly experimenting with some anti- ackerman to get a bit more slip angle to the loaded tire.

kila. that mini looks solid. might want to move the wires going into the receiver though as the motor might melt them if you drive like hamma.

any info or link to ta05 mini stuff?

drove it today, it hauls......i still need to setup the suspension and gear down quite a bit. but with a little tuning this should be a great car to run in our fast 4wd mini class, im even considering running this thing in the regular mini class, with avery. it should be pretty easy to get it to the correct FDR.and a black can would throw this thing around like its nobody's business.

Well I thought I would just post pics of this thing

I got it from B when I bought his M04M from him ( Big Mahalo's Again for the hook up B!)

I believe it is an original Xpress Road Runner Mini?

It is in pretty good shape for as old as it is and I don't think it has had much use recently at least?

Would like to get some replacement parts for stuff like the hinge pins and maybe bearings. Most of the other parts look o.k.

Been doing some research and was glad to see they still make some parts for it, but not a lot. Also it looks that some of the parts from the cars that followed this one will work on this one. But have not confirmed that yet? It seems that even some parts like suspension and diffs from the newest car may fit as well? Again not confirmed.

I have not had a chance to run it yet. But have tested it in the house and all parts move fine and no strange noises!hehehe

Right now I have a EPIC Outlaw stock in it using the stock Swift esc. I may bring it out to race it one day? Of course with the legal motor in there
