i run an lmt 1950/8 non high amp with a quark 125b on 5s or 6s lipo. i have a problem though. the quark doesn't work properly on 6s. from what everyone claims 4s is great with the quark, so i would like to run a 1950/6 on 4s and 5s with the quark. what would be the performance differences if any? thanks, tally!
