I guess my question is this: I'm building a 4*120 which should weigh around 12.22-12.75 pounds when done. If a DLE 20 has 14lbs of thrust with a 17-6 prop, then will the plane have plenty of power? I've had some say the DLE 20 would have more than enough power, some say it would be light on power, some say a DLE 30 would be better, some say the plane would be ridiculously overpowered with a DLE 30. The answers I've gotten are all over the board...
