Dear friends,
I just to buy a old H-36 Dimona motorglider. 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.
Angel
