if you've got the slipper you may be ok, but the diff has no plates and the bosses wear quickly and bang goes the diff( ive had a new diff fail within one heat running a 19t motor), the top shaft in the gearbox is not the greatest with brushless either, a couple of people i know who run them with ezrun systems had some new alloy ones made to stop the wear.
It can be done but you'll have to call upon your own modelling skills
I was going to get myself a new cobra last week but after speaking to Chris at Mardave decided to wait for the next couple of months for the the new with all the old little niggles sorted and ready for the next 20 years!!
