i have a .51 supertigre engine and i was wondering if the u-can-do .40 or the funtana .40 would work well with my engine. i just want somthing to learn to hover. i know most of you guys use big 4 stroke engines at least thats what i usually see but will my .51 give either of those planes enough power to have vertical? any help would be appriciated as well as other suggestions
