My T.O.P Scythe weighs in at 1340g ready to go for dry racing, and 1370 with waterproofing for the oh so common rain

The Much More tyres are not the same as Sorex.

It is a lower profile tyre than both Sorex and VTEC.

I know of at least one factory Tamiya driver who has machined the bulkheads hollow aswell as other alu parts to get it under 1350 with brushless...a bit extreme, but shows it can be done.

Oh and yes, the Much More tires are not the same as Sorex as kentech said. Lower profile and more grip actually than sorex 28 and CS22.

But 30 runs and they're shot...on carpet...

How are you guys correcting the balance of your cars? Of course it isn't as easy as sticking some lead down where the missing cell is as you will be way over weight!!! Is the easiest way just to move the receiver over to the right of the chassis in front of the cells?

I don't think you need to move anything as 5 4300mAh cells is heavy enough to counter motor+ESC+RX+servo, UNLESS you using some crazy heavy device.

My TA05 balanced well with 5cells EP4300, no fan no heatsink. Nice! (with 6cells, I need to add at least 30g on ESC side, and it still not balanced well)

Ive heard from several people something you might think of some kind of paradox: with 5 cells the motor and speedo gets warmer than with 6 cells. My inital testing have also shown some indications on this (GM-BL).
This cant be good for anyone...

Thats weird...
I noticed the GM BL specs says its operated voltage is 7.2 - xx.

Maybe this has something to do with it?

This cant be right. Both ESC and motor are cooler in 5cells than 6cells. The only thing that might get a bit hotter is battery.

Could be a GM-related problem. But their Genius 70 is also specified 7.2-xxx but it works fine in 1:12....even without Rx-battery.
