Hiller's are great!
We have owned and operated many hillers throughout the last 25 years, maily E models and one soloy conversion.The soloy would easily lift its own weight and more it may be a bit slower than the 206 but it's a far better work horse.
We still maintain Hiller's mainly E and C models in the UK ( well there is only the one E flying at the moment ) If you have all the right contacts there isnt much you cant get for them.
The art in the Hiller is to start from the ground up and set all things correctly, take your time setting up the head and blade assy before you even install it to the aircraft then a good set up on tracking and it will fly nice and smooth.
anyone needs any more info send me a pm.
