Here is a weird Rotodyne that I just discovered this evening. I know you mentioned it in the post regarding China toys. MF-821.
Unlike the true Rotodyne, the toy has a single fin which might get in the way of the rotor's wash.
A truly strange feature is what appears to be fuel tanks on the stabilizers (or perhaps they are jet engines like those on the wingtips of the French SNCASO Trident)?!?!?!?!?
The seller states the length is 26 cm. /2.54 = ten inches.
