Dualsky XC550 question

[Chris56]

Im really temped with the £65 Dualsky esc - I notice that it is rated down to a 6.5T. Out of interest, how well does it handle a 6.5t in a 2wd buggy? any overheating/cutout issues when advancing the timing?

Im also tempted with the SP Reventon-R, but am wondering wether it is worth the extra £20 when the fastest motor I will be using is a 6.5T in my TLR22
