Oh boy..............this ought to be good. He may have the interest of which I admire but not the HP to get that 'thing' airborne! At best there's a total of 10 to 15+ HP by the looks of things & that is typically used for toy planes weighing in at around 20+ or Kg's. The props appear to be Master Airscrew brand (used on toy planes) placed back to front in order to produce thrust in a rearward fashion. If that is the case then talk about inefficiency!
Hopefully someone will guide this keen young fella in the right direction to fulfill a dream of a memorable flight rather than a memorial one !
