First post, sorry if I mess something up. I have a 1300 kv, 420 watt motor but can't figure out how to make a plane around it. I know how to build most of the plane I just need to figure out what wingspan to use. I used a calculator on radicontrolinfo to try and find out what the dimensions should be but it spat out ~61 inch wingspan which felt large for my small motor. Can anyone direct me to a resource or just give me a rough estimate of what wingspan to use? thanks in advance!
