Re: Xkill's mini
 

Thanks for the kind words.
First I have to make it run and then we will see how it performs.

If everything works as I hope I'm considering making the parts available in http://thingiverse.com/ so anyone can print these parts for free...

Re: Xkill's mini
 

Nice work on the chassis, it is very hard to find a bodiless chassis for the MRC.

Ops...
I might have over done it....
Already working on a new version using 32P pinions and only 2t difference.

Re: Xkill's mini
 

That's quite a lot of OD/UD. Just don't ever need to back up. LOL

Re: Xkill's mini
 

True....
But the main problem was that the pinions for the OD would not survive much.
So I'm working on a version with less OD (2 tooth difference instead of 6).
We will see how it goes, but time is running out for me.

Re: Xkill's mini
 

Damn, you are a mad genius!

Re: Xkill's mini
 

The switch to 32pitch pinions in the front was a great move!
Why didn't I go this route in the first place?! :roll:

Just waiting for pinions to do the same on the rear.
I will be using 13 and 15t pinions.
The "ticking" sound on the video is the pinions in the rear skipping teeth...

Re: Xkill's mini
 

So, I guess I should do an update to this right... :roll:
Was waiting for a long time for the 32pitch pinions to arrive so I could finish the car.
Customs held the package for more than a month :shock: and I finished the car the day before traveling to Austria for Eurocrawl.
I went one day before the comp and used that day to test the mini for the first time.

I have 15weight oil on all 4 shocks and Dravtech supersoft springs.
The rear right was bottoming out a lot so I changed to soft (same as losi pink spring) and it was better.
Going uphill the dlux weights are awesome, going downhill is a totally different thing... The car is super front heavy and the brushless combo gave me zero control on downhill. Definitely one of the first things I have to do something about...
Just before leaving home I changed the from inserts for some memory foam on the outside and a harder, home made, inside foam.
With all that weight the front was washing off on sidehills... Foam tunning is also on the to do list...

Still, the car was a lot of fun to drive!!!!
Zero issues and everything held together, only had a few "clicks" on the front end when I pushed it on a bind...

I'll post pictures of the complete car and later I'll post the videos of my runs during Eurocrawl.

My kids painted the skins of the Mini and the Pro car!
They was super happy and so was I!

Also added some weight to the rear...

[IMG]https://live.staticflickr.com/65535/...a155796e_c.jpgSAM_4151[/IMG]

Rear upper link support.

[IMG]https://live.staticflickr.com/65535/...7318c128_c.jpgSAM_4152[/IMG]

Rear UD case is 100% closed, unlike the front for clearance issues.

[IMG]https://live.staticflickr.com/65535/...464e3b51_c.jpgSAM_4153[/IMG]

Front OD.
Next to it is the battery support and above the ESC support.

Tire gets pretty low from all that weight...

[IMG]https://live.staticflickr.com/65535/...404212d6_c.jpgSAM_4156[/IMG]

It's a tight fit but the receiver fits behind the servo and it's well protected.

[IMG]https://live.staticflickr.com/65535/...10a8026c_c.jpgSAM_4157[/IMG]

Still want to try and get a few more degrees, but will have to redesign some parts...

[IMG]https://live.staticflickr.com/65535/...a27cd4bf_c.jpgSAM_4159[/IMG]

The combo is very nice, going uphill...
Lot's of control and enough power.
I wander if a micro x will be better downhill...:roll::roll:

[IMG]https://live.staticflickr.com/65535/...d64a8a75_c.jpgSAM_4160[/IMG]

The SDI shafts are nice and twisted but no major binding.

During Eurocrawl I got 9th out of 25 drivers and was super happy!
Even more amazing my spare parts car (Mini Pro with a CF gatekepper, stock motor and weights on the wheels and traxxas OD mod), was finished in the morning of the comp and was shared by 2 of my friends. One of them got an amazing 7th place!!

So now it's time to tune the car and iron out the bugs.
It's a lot of fun driving this car! :mrgreen:

Re: Xkill's mini
 

That's awesome!

Re: Xkill's mini
 

Bump all mrc threads lol

Re: Xkill's mini
 

Bump to your bump!

Now with Outrunner power ;)
But still some more testing to be done...

Xkill's mini
 

Did the od/ud file ever get posted? Getting a printer soon and would love to test it out.

Re: Xkill's mini
 

Mini is still being fine tuned.
It is now lowered and with a new tire in the front.
I'm not happy with the recovery problems that the servo location gives me so I might redesign the whole front end...
Also, the Servo is getting SUPER hot.... I don't think it will have a long life...

Re: Xkill's mini
 

Seems to do quite well! How ya feeling about that outrunner?

Re: Xkill's mini
 

Very happy with it.
It beats the inrunner hands down!
My main problem with the inrunner mas downhill control. I had zero of it!
Basically the car would just take of, I could not have controlled decent.
Now I have all the control in the world!

But it's not all roses, I had to move from a 2s to a 3s lipo...
And I will probably go one pinion up, from 13t to 14t.
