Need Help Choosing a Plane Hello everybody, Im having a difficult choice between two planes, and thought that the people on this forum could help. The two planes I am deciding between is the: "Hobbyzone sports cub S"...

I went to my local hobby store and came back and my motor at first wasn't running very good. it made a weird pulsing noise. then i tried it and it only rotates at ~600 rpm. (normally 20,000 rpm) I checked my battery and it was reading 11.7 V. So I'm not sure what is wrong with my E-Flite 30...
