Don't solder when you're so tired you can't see, kids.

Opps.... Don't worry, many of us have been there, done that before

By the way, it's also hit the rc-mini workshop, and our full review will be up soonish...with xmas in the way it might take a bit longer than usual..
Hmmm. For once, I think they are priced better in Japan. Maybe I should bring a few back, then.

One other thing I found (not sure how recent it is) Tamiya released the R5 Turbo GT2 again on a 1/12 platform as they call it. I had a look at it in a shop here and it looks like a normal M05.

There are also conversions of all kinds mainly for Tamiya kits, including a TA05 to make it a mini (don't remember who makes it), and a full carbon version of the M05 made by Tech Racing. Amazing stuff in hobby shops at any rate.

I'll check again the pricing on the M Four kit.

The cheapest I can find it here in japan is 31,500yen which, given the exchange rate is actually more that the pirice listed above.

I soldered a deans female on an esc and as my soldering is not
my strong point this was spot on heat shrink tube the works
Then i realised what i had done !!!!!!!!!!!!!!

Just my theory..
the batts a constant(sorta) DC voltage source, not an AC source where caps are used to smooth out ripple from voltage drops from + to 0 to -
You are correct.
These caps are banked with resistors once fully charged they throw a spike of voltage, its short, but it keeps pulsing higher voltage.
And voltage is speed

There are also different capacitors for acceleration and top speed.

TOP .15F (for top speed) <- stores more energy but delivers it slowly
Keyence Chevalier (for acceleration) <- stores less energy but delivers it fast

Both capacitors deliver energy faster than a battery. Preventing a low voltage input to the esc.

And if you combine both, then best. Just my experience.

I've also checked rc-champ, their price is even cheaper again as 28,224 yen.

Of course, they're both internet shops, so the cost of sending is on top.

Here are some Mini Mod tips to make your Mini faster:

(1) Use strapping tape to hold your batteries - no side braces

You can adjust your weight bias left to right to offset your batteries from center.

(2) Remove the two chassis braces from the chassis for more rear bite

(3) Add a small rubber band to the steering ball to steering ball to keep the arms swept back to remove play and wheel wobble

(4) Remove all transsmision ball bearing covers and grease - dry and lightly oil with a synthetic lubrucant.

(5) Add a light spray of silicon to the plastic transmission gears and then add a dry graphite powder

There's more later...

Need help. Purchasing a M06 chassis kit but have no idea on what body to get for racing? Have a M04 Miata body.... would that be legal?
Thanks in advance

The Miata shell is legal for TCS, as are the new RX7 and Alpine shells. In Tamiya's words
Any Tamiya MINI body parts set made for the M-03, M-05, M-06 may be used on any chassis platform.
I really doubt tat they'd have any problem with using any Tamiya shell on any Tamiya car. They used to have a rule regarding body matching which wheels were driven, but they started releasing RWD type bodies on FWD platforms all on their own. Put an end to that rule.

Glad you guys have had good luck with the 3 Racing universals. I was afraid to try them because all my bad experiences with their products in the past. They are certainly cheap enough.

Finished a full day of testing with only one minor glitch which was easily correctable and was due to a misimpression of mine and was not the fault of the R1 Wurks CVD unit. The units performed beautifully all day and were perfect at the end of the day. I loved the fact there was no play in the unit and did not have to use any axle shims. I was also able to add a 1mm spacer to space out the wheel and still had full contact in the nylon on the wheel retainer nut.

So far, all the local Mini racers here at the Tamiya USA track have been impressed. I was given the units to test at their urging. What they said was " Have Granpa test them. If anyone can break them, he can". One of our local Mini gurus was convinced after seeing what I put the units thru today.

only two worth doing is 4 and 5, but on 5 i wouldn't use graphite power, no point, the silicone spray is good enough

just my opinion
