The one thing about this hobby is that there is NO limit to what we can imagine will work.
Keep up the good work.
Just imagine 10 years ago even thinking that Tricopters could fly.
A POX on those who limit their vision on what we can achieve in model flight.
Remember- the sky's the limit and there is lots of that stuff.
