What's difference between - Speed Passion GT V2.1 ESC Pro Stock & V2.1 EX Version

[carlin]

Hi Guys,

I'm bit confused whats the difference between these two Speedo's

Speed Passion GT V2.1 EX Brushless ESC vs Speed Passion GT V2.1 Brushless ESC Pro Stock Edition

It's to run with my FS2 4wd on a 6.5t SP V3 motor.

The EX says ok for 2wd but doesn't mention what about 4wd it's more about running onroad 1/12th & 1/10th stock.

Any advice would be great, which model does Lee Martin run on his?

Thanks

the 2.1 ex has a low profile heatsink and can run 1cell lipo with out a battery pack for the rx and servo, its for a 1/12th car

Ah right thanks, so which one best to run in 4wd do I need fan too?

I guess no body really runs these models in there cars?
Or SPassion ain't that popular nowadays.

I've took the plunge gone for this model to run in my 4wd with 6.5t SP V3 Motor

SPEXT98802SCB Speed Passion GT V2.1 Brushless ESC Pro Stock Edition

Fingers crossed :D

That model should have the turbo profiles loaded onto it rob but shouldnt really be needed for.your 6.5t. Handy to have anyway though. Buy the program box and then you can update and change firmware to whatever you like then.

Yeah I got a program box already a HWing one which works with the SP models so should be fine :D

I run a 6.5 on my speed pasty pro stock in my 2wd no problems whatsoever

But follow the recomened guide lines and you'll be fine

I'd say the 5turn is max and aimed at Onroad
I would say 6.5turn Offroad as the demand is higher !

But I'd temp check just to be sure !!
