Scotty, as I understand it, the Tech 'conversion kit' uses the original M03 arms and uprights..and that's it!!! So the use of the word conversion is dubious at best.

I already have one of the Active Hobby cars fleagun, and its damn good actually.

We run the 4WD Minis at indoors only, I dont think its a good idea at all to introduce them into normal racing, unless they had a 'special' class. And to be honest, we probably have enough classes as it is.
The 4WD cars are just a bit of fun really. For racing it's M03's all the way..

good to hear tony, I think the active hobbies mini would be great in stock or modified. should have a good power to weight ratio?

You're right though, M03 all the way for racing!!

The tires, rims and motor look like tamiya. Oh maybe the wheel lock nuts and body clips too :P

Mini Servo saver Replacement
 

What is the best replacement servo saver for the M03, can you give me the brand & part number if possible
thanks

The original one is actually the best.... Most others are too short. Why do you want to change it anyway?

servo saver
 

The servo saver from the Tamiya Mad Bison is identical to the original M03/TL01 servo saver except it is made with stronger/reinforced plastic. It is dark grey instead of black. It is of course the same length. It can be further stiffened up by putting the outer spring of the Tamiya hi torque servo saver around it. The Tamiya Hi torque servo saver is commonly used but is shorter and causes more undesirable bump steer.

I put a small tie wrap around the spring on mine. Works great.

where can i pick up a cheap M03M locally these days?

How much do you tighten the TA03 ball diff for when using in the mini?

Hi Dave
drop Greg ( Cannon ) a PM i am sure he can guide you in the right direction

Build it as per the instructions; So it should be done up "tight", not like any other TC ball diffs where you can adjust the pre-load/diff action.

They can still come loose in operation after some time, so it's a good idea to check when rebuilding. You can also add an extra small coned preload washer to make a tighter action as an option.

Regards,

Thank you for that

if u use your mini everyweek, ball diffs r a waste of time and money ,a well constructed gear diff will be more consistant and last longer

That didnt help Dave Willard in the SMA Mini Enduro. I ran a ball diff and it was awesome. I won by four laps. :D
Z-Mann is right though, ball diffs are expensive. With a normal gear diff, you have to loctite the three small screws that hold the diff together and lube the gears with anti wear grease. This stuff is sticky as and will slow the differential action and ultimately aid in getting the power down early when exiting corners. A ball diff will help on corner entry,and you will have a less chance at traction rolling but if you power out to hard you will wheel spin and therefore slow exit speed.
Personally i like a ball diff, but it comes down to the way you drive. Mini's are about throttle control.

Hi, i´m new on this, and i´ve trying read al lot here, but a want to lear about how to get the best performance or setup for my Gear Diff, i was looking for a ball differential but i´m not decide yet. And if i don´t have some things that u recomended for the best setup in the gear diff, what other could be work on it?, i mean, i want the "Well Constructed gear Diff) i use my mini 2 times during the month, 2 weekends....

Thanks a lot! and sorry for my english...i´m from Colombia!
