[pipeous]

I have a Sidewinder in my B44 with a 5700 and running matched packs. I don't think I'd push it to 4s even without some cooling. I even wonder what 3s on the 5700 would do without cooling. I think take it for what it is, a super inexpensive brushless setup for 1/10 racing that fits in a smaller space than the mm. 4S on the MM is pushing it's limits, so if the SW is 60% capable.... I know a lot of guys push things to the limit, but for performance it's better to have too much headroom than too little... besides, I am very superstitious (born Friday the 13th) and letting the genie out is bad voodoo
