4WD shaft mod + 180 motor mount

[mini-xmen]

Hi,

I had the problem with the traction roll only with motors equipped with neo magnets.
I am driving on pvc rooms. Very very soft in the rear, if I press the car down, it stays on the floor. In the front it comes up a little.
With this setup the car drives perfekt. Rear diff as light as possible befor slipping to much, front a little lighter, because of weighttransfer.
On asphalt its another story.
You don´t have to be afraid of your esc!!!! We are driving on track with smaller ratios and 7,2V. The fets get only hot if you are driving not full throttle all the time!!!!

The axle has a diameter of 2mm!!! We take steel wire.

Now I will test the HPI modified moto, but its silly expensive.
Waiting for Ebay. That will be the largest motor you can put into the mini-x without getting undriveable.

Good to hear the ESC's holding up ok! I tend to roll a lot as well, my batteries are really big though, and the receiver's on top, so since I ground off the little stops, I’ve thrown off the whole geometry. I'm using the tires from my Kawada, as they're thicker than the x tires or the mini-z tires. I'm gonna get Overland tires, and extend the offset of the wheel using some sort of plastic tubing, the same diameter as the X’s wheels but wider, and putting the tires on the outside, creating a 'deep dish' wheel..
Hopefully this should widen the track enough to lesson the roll factor...

I found a place that sells mini-x fets (the 30100's) for $4 a pair. My question is what will this change the capability of my ESC to? Will it up my A handling by 50% or is it not a linear scale? Is A handling even the number I'd be worried about in this case? I've heard that the stock v2.0 mini-x ESC handles 8A, but I'm not sure if that was continuous or peak.

Hi,

I'm using the Mini-X ESC v2.0 in the HOR and in the M18, with 6x2/3A cells & 300 or 280BB motor.

Never had a problem with FET (stock one, no extra added) !

In my M18 with the stock HOR motor (a 200 motor), due to a high gear, the motor get extremly hot ... but my ESC has no problem.

The Stock mini-x ESC is quite capable .

Remeber that in the stock connections, you just have forward and reverse ... if you switch fast from full forward to full reverse (or vice-versa), you could easily burn out any motor !

In case you want to have forward + brake (loosing the reverse, my set-up in the HOR), just plug the battery plus to the motor plus & the ESC, and plut the ground of the ESC motor to the motor ... in this way you have a brake and even more powerful ESC (you just cross 1 FET instead of 2 FET ...)

Have fun.

P.S: My stock Mini-X has so poor performance (just Neo Magnet added, and the stock 6 cell pack) ... that I have gone from 4WD to FWD ... the car now handle better and with more top speed !

Also FWD look like it is more heasy to handle then 4WD ... my 4WD was doing a lot of unwanted 360 deg turns !
