I've got the core code tx

So, Mini finally goes brushless. Time to get the M03 off the shelf and build the M05 sitting here still in the box.

There are a few of those being run in mini here. Good batteries. Anyone know if Hobbyking has gotten over the international lipo shipping problems yet?

Statement about the battery says "looks like they'll fit Minis" so anyone know if they do. Hard to tell by the photo.

They do fit fine in the M05! The only thing is you have to trim the opening in the removable battery holder part a bit so that the grommet of the battery can go through.

I've been using these packs for a little over a year now. I didn't trim my M05 battery cups (the grommet it a bit squished). I even have a few weights added to the underside of the pack, no problem. It's a REAL tight fit in my M01, though, but that car is relegated to shelf duty now.

[/QUOTE]You can always tell when someone shows up with a silver can in their car. The 21.5 cars are quite a bit slower down the long straight than the silver can cars.[/QUOTE]

I can vouch for this. Swapped a 21.5 Hacker from my TC with about 40 degrees motor timing into my LWB M03 Mini and was getting pulled by a box stock M05 on a long straightaway. I had been running Silver Can in a TCS type format at my Summer home but had an extra Tekin ESC I used instead of the original Tamiya ESC. Decided I might as well put a BL in for racing in a mixed Mini class at my Winter home in AZ. By mixed I mean if it's small it's in the class so that includes 4WD Vaterras. The most recent race even had Spec Touring cars to help make up the class.

I got so frustrated I put a 17.5 in with boost and turbo. Got the speed but the Vaterra clobbered me and broke a rear upright.

Interestingly when I ran the 17.5 the first time I only had motor timing and really didn't see much speed difference between it and the 21.5. Different motor manufactures as well and I don't know how their KVs compare.

Think the Hacker is the better motor and since I now know the 21.5 is legal for TCS ,after coming back to this thread following a few months absence, I'm going back to the 21.5 and I'll work to get more speed out of it.

Hi all,

I won't be racing my M05 until next year so won't have time to experiment :cry:

Has anyone tried kit tyres on the front of an M05 on carpet? I've heard some clubs are using kit tyres with additive on the front and M grips on the rear, this is to help with the twitchy feeling of the M05 on high grip carpet.

Anyone tried this?

VooDooPH 12-11-2013 06:06 AM

Ive tried kit tires in front and s-grip at the rear... both with the hard inserts... worked fine although i think i could have used a little bit more steering for the low speed tight s-curves...

Cheers,
So am I correct in thinking that hard inserts will give the car less grip?

17 flat was the fastest I went with your silver can Granpa, and that was hustling the mini on clean, tight, no scrub lines...the BL guys were doing that cruising middle of the track.

Yeah Rod, and that particular motor might be a tic faster than a TCS legal Silvercan. Best I did that day was a 17.3 and most were in the 17.5 range. Just goes to show what a good driver can do with a Mini, cause my car is a few tenths better than yours. But since that was the first time out for your car, I'm not braggin'.

On our carpet the kit tyres come in a poor second against the M-Grips. We aren't allowed additives though.

Not necessarily imho... they're not that hard and minis dont go as fast as touring cars so the dynamics are a bit different. the harder inserts helps the tire retain its shape especially around corners... keeping a fuller, more usable contact patch. Softer inserts might fold "more" during corners giving the tendency for the car to "hook".

Thank you Sir, I'll order some

It's the 53255 ones right? (60D)

Cheers!

Hi guys,

I have in the packet an unused M03 mechanical speed control. Are they worth anything??

Cheers!

Is there a hi-torque servo saver in there somewhere ? You'll need one.

Nope, that I still have to pick up along with some paint. I'm still undecided on the Tamiya or Kimbrough one...I guess whatever they have in stock.

I've used the Tamiya hop up servo saver and alloy horn on my M05 for a while now and even after lots of crashes :blush: it's still pretty tight.

I'd be interested to hear how the Kimbrough performs though.....

In an M05 I wouldn't use anything else but the Kimbrough. It centers better and has less lash. In a M03 the Tamiya one has some advantages because it's easier to get the bump steer right.

monkeyracing 12-13-2013 11:16 AM

Kimbrough! I've got several Tamiya heavy duty models and find they get bound up one way or another, even with mild contact. I use Kimbrough in my 03 as well. Usually L or XL, re drilled/shaved down for proper alignment.

Boostinswifty38 12-13-2013 11:27 AM

Still selling my Mini Cooper with hop ups if anyone is interested. M05. Pm me.

I hadn't thought about re-drilling it.... #derp

Does anyone know the Tamiya part number for the tcs legal 60d radials?

#1016 for the S-Grips

#1028 & 1029 for the Type A slicks

Thank you Granpa trying to get my Dad something he can use for Christmas!

Most seem to like the #1016 premounts the best. In our locale, no one uses the slicks.

Boons 12-15-2013 03:01 PM

A question for you :D

So in silvercan form, and on carpet, and experienced driver(s) etc, what would you expect to lap fastest out of an M03, M05 or M06?

Just curious and not intending to cause a riot! :p

I race an 05 and my Dad drives an 03 and it seems like the 03 is faster than the 05 . At the tracks we ran at this past season with both the TCS series and the local races it seemed like the 03 really had the advantage over the 05s. We really haven't seen any 06's run yet so I cannot comment on them

Granpa 12-15-2013 09:08 PM

M03 vs M05. We've had that debate here several times. The M03 wins most of the TCS races regardless of the track or surface. The TCS series uses a Spec 60D tire. This also may be cause most of the veteran Mini racers prefer the M03. In any case, pick one and stay with it cause they do set up differently.

I've been an advocate for the M03 after building a couple of M05s. Nice car, drives easy, sloppy steering that needs shimming, but it's just a little slow. With the 21.5 B/L motor rule tho, the M05 may warrant a second look for obvious reasons.

It's kind of an apples and oranges question. If there's loads of traction, the M06 might have a better chance, because it can take advantage of it more readily. Between the 03 and 05, I'd say it's a dead heat. Really depends on setup and driver.

Anyway...subject change... Anyone ever had to change their 500,000wt diff oil in the 3Racing gear diff yet? What colour was it when you opened up the diff? How do you get the old crap out?

I'm letting gravity do the cleaning at the moment and the oil is dark grey. Thoughts?

Jim

Jim[/QUOTE]

I built my 3 Racing diff with 5000cst and done about 7 or 8 nights racing. It still feels fairly tight but I'm looking to go to 100,000cst in the next few weeks.

I've heard of people using the 500,000cst, is that personal choice or does the diff really loosen up over time?

I)arkness 12-16-2013 01:38 AM

oil in the diffs will go black, its normal, as for cleaning i wouldnt bother just top it up, unless you plan to change thickness.

as for them getting loose, will be from oil leaking out of the out drives as the spin. no diff is 100% sealed

monkeyracing 12-16-2013 03:08 AM

No leakage, but it did loosen a little. Most likely I didn't fill it completely when first built.

EDIT: Gravity did a fair job. Woke up this morning to mostly clean parts. Refilling the diff to a slightly higher degree than before, but hopefully not so high as to cause problems.

EDIT EDIT: how much do you guys fill them up? Do you go to the pins, as per instructions, or do you go the Paul Lemieux route and fill the whole cavity?

caltek1 12-16-2013 10:56 PM

Jim,
I use 300 000 weight and go to above the pins, but leave a small airgap. I also use lots of green slime on the o rings and gasket.
Regards,
Calvin.

Yes, a fair amount. Depending on your location, and if you run a Tamiya, TCS Track most Saturdays...:nod:
