Hi All,

I have been thinking about jumping into the Mini realm and was hoping someone could give me a few pointers.

What chassis is good for a mini beginner such as myself and what are the essentials required for it?

thanks guys

I created an m01 m02 Fcaebeen group. Join it please so we can discuss this awesome chassis and show off your build

M07 and M08 got their own threads, though.

Question for the TCS racers who used to stiffen up the diff with blue-tack, anyone got a photo of hoW much and where in thediff it went?

I've locked up diffs with blue-tack before which just Involved shoving as much in that fitted, but the rules at the track I'm going to run at say:

- using the Tamiya kit diffential components only
- Oil type sealed diffs are NOT permitted
- Ball differentials are NOT permitted
- you MUST retain functional diff action at all times

which lead me to remember the blue-tack method from the M03 days except I don't remember lhow it went to get about 80-90% stiffer.

Ofna diff lock lube is the best...Limited slip diff with lots pull out of the corners, no wheel spin...Works on gear diffs, ball diffs, slipper clutches, etc....

Find some silicone earplugs and just pack the whole diff with them. Much easier to deal with than blu-tack and will make the diff very stiff but still functional.

Have you actually been to a track or an RC shop in the last 20 years Bert? Ofna have been out of business for ages.

Ofna out of business does not mean their products are any worse than anybody else's. You just have to find it on ebay or something or you can try energy suspension polyurethane bushing grease($18) for more diff action than the ofna diff lock lube but still stiff enough to stop diffing out... Bert Knowledge is power !!! LOL !!!

It's not on eBay or anywhere I've seen. Being out of business for years has made it unavailable.

You have to keep looking for over three months on ebay to find someone willing to sell his stock just as I did a while back : the world does not revolve around you....ok...If you really want it, you'll find it...Life is hard. Wake up !!!

That's your advice to someone who wants to fix their diff now? Wait for months hoping for a discontinued product from a dead company to randomly appear?

bertrandsv87 04-18-2026 05:00 PM

Use the available energy suspension grease now while still looking for the ultimate Ofna diff lock lube. Take it or leave it...Stop crying !!! Lots of cry babies down under...WOW...
