I recieved my Hornet undercarriage after waiting two years. I sought the assistance of legal council whom told me I had every right to be annoyed. Keep trying to get a hold of them, they will come through with the goods, allbeit very slow.
All my advice is to any CBM jet owner still requiring parts is keep hounding and ye shall recieve (though it should never be that way with business!) My advice is to seek the help of a lawyer, they do good work
