i have fitted a speed 480 race motor in my rc18t.. it has crazy speed now,, almost comparable to he mamba 8000.

since the mini inferno comes with a 400 can motor do you guys think there is enough room for the speed 480 motor,, ,, and this motor with 8 cells rocks,, im currently using 24t/55t with both 8 and testing 10 cells is insane,

It comes with a 380, not 400. :p

..i dont think it fits...we are stuck with a can length same as stock :( If its shorter than stock you are fine...

the 480 is roughly 50mm long. How does that compare to the stock can? :)

...The can ONLY is 37.8mm long...the WHOLE motor is 57mm tip to tip...2.3mm shaft...

hkopium-- from what i have experienced,, the 380 size is about the same if not the same size as the 400 can,, not much difference,,, the 380 is definaetly bigger than the 370 that is for sure,, 370 is like a 300can and the 380 is like 400 can,,, bu it sure would be nice and fast to have the speed 480 bb with a large pinion in that half 8,,, speeds would be equal to that of the mamba

hello guys,

Well, the 480 DOES fit, but with some modifications :
- head of the motor (turn upside down one of the brush holder),
- steering system (I've used a contersunk screw, a servo horn, some aluminium washer and some ball bearings to replace the original part and to make enough room for the motor to fit),
- motor mount,

Easy-to-diy modifications in fact, I've test-run it against a mamba'd mini-T and it rocks... The only worrying point is... the slipper, which i have to strenghened to allow the power to pass through, but top speed is OVER a mamba 6800 with 11 tooth motor pinion for the losi and 21 (yes, 21 !) for mine on the streight (just to give you an idea of how fast it is)... Second worrying point is that with GP 1100 (6 cells), you can only run for 5 minutes...

Some photos to be added soon, once I've tested it on a real off-road track !

Grosquick, if it's posible, after test, tell us about motor heat. Perhaps it gets less hot than a mamba.

Hello,

Yes, it does stay cool enough ! no comparison with baja or other stuff when i runned my own mini-T...

Seems like we are running into runtime issues. 1100 mah may not be enough for these motors.

...my xspeed got SO hot today it made my gear cover start to disfigure...we couldnt touch it and it was smelling from the cooking oil inside or wherever it was..it was really nasty...I bet the mamba gets TOO hot...I hope the K4 can stay cooler...Only time will tell...

..WhoMe..interesting point...maybe we could make a pyramid of 2200 cells? 3 each side? Four?

that would be interesting to see. I doubt that the k4 will be any cooler. I have heard from "someone" that it is based off the 4.8 speed 400 motor by graupner. This motor was designed for 4.8-7.2 volts and that is why it gets so hot with lipo or 7+ cell usage. However, atomic makes a heatsink for the mini quake/anderson that should fit perfectly in the kyosho. Just cut a hole in the windshield and that should definately drop your temps.

...i have two of the quake sinks on my xspeed..see pics in 'Vintage'...cut a hole in front of body but no good..more dust that air....cutting winshield today though...

Somethin like this (http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&category=2565&item=5969528204&rd=1&ssPageName=WDVW) could help with heat. :)

....Yeah i have started to think about putting a fan in...its either that or cooling it with a really big ice cube :eek:

go with the ice cube, it wont draw any extra power ;)
