I don’t work for flipsky, but this has to be a pretty good deal. They’re in theory offering buy one get on free on any 6.6 FSESC, meaning you can get the heatsink one for $155, ship it for another 20 and tax for another 20 for a super cheap dual 6.6 setup.

I just saw this on Facebook before. It’s so bloody tempting. The problem is I’ve seen lots of people having problems with the 6.6s. Mostly over current on acceleration or braking
