Hi! I am thinking about trying a project to fly my rc car. I have a power pack C for propulsion and was planning on building the airframe around the rc car so that I could still drive. The car weighs a little less than 6 lbs, and I think the power pack C weights a little over a pound. I think it will give me around 2.5 lbs of thrust. So with the right wing, is it possible to fly 7lbs with 2.5lbs of thrust?
