Thanks for the info fella's. the reason why I asked is because I got a 12 t etronix unsensored....which goes like the clappers and I get wheelies on grass using a b4 & 4000 2s 30c lipo ....this I can honestly say never happened 10 years ago.
MY lad has also got a b4 with a 17 turn brushed which is only slightly slower than the brushless...but the brushless seem to have a lot more 'grunt'
