A few of us are thinking of doing this and we may get together an have engineering plans drawn up.

The plane are in good conditions don't have many hours of fly, but have the old taildragerwheell and I want to replace for a Sprung tail wheel. I should be grateful if some body can help me to find the sprung tailwheell to buy, because in Spain is a litle difficult to find, no many H-36 fly in Spain. Thank you in advance.
