If you notice the engines, turbine jets and edf fans. I say large scale should be fun and also FPV, fly it at your golf course under the trees, over the trees and around the trees. That would be a blast!
well it's good, needs to be better, size is about right, more speed and doing it out doors at night would be awesome! and do both high speed turbine jets and EDFs and do high speed FPV race with all the racers.
The star wars pod racers hovered using some sort of anti-gravity before they set off. So not ground effect, since anti-gravity hasn't been reinvented since the galaxy a long time ago and far, far away hover-props are the nearest thing
