It's not helpful, because it wouldn't help anywhere near as much as you think it might. I can guarantee you'll crash just as many times trying to work out how to pilot the VTOL as you would in building it from scratch. If I did make and release it I would be flooded with just as many people asking how to fly it, because taking off is harder than landing, and in general it flies like a brick. A sporadic, ill-behaved, angry brick, with the turning circle of Minimus and a half.
