so i got a decent deal on an x cube 2 and a tfv4 mini ($65) over the black friday weekend. the x cube is a tank and has more settings than i care to learn (i hate destruction manuals) lol. and the tfv4 mini seems ok. i love that it comes with an rba deck. i'm wondering if i sould be looking for a better tank or do i have a good one? now and than it seems to leak some juice out of the airflow holes. not sure why.
