Hi! FS98ers
Nice surprise finding  Cayuse YV1801 on FS98 downloads. I uploaded this chopper model to Keith virtual helipad, finished to be published on July/02/1999, The first long legged 500C, rebuilded the obvious parts that distinguish the Cayuse from the 500D, departing from Navin Bopitiya's AFX file on Hughes 500D. Then added moving parts with aircraft animator by Constantin Kukushkin, by that time could not sample real aircraft sounds to complement the job.
I´ve a 2D concept model in two colors, Developed Then with Af99 on PentiumIII 550 + Creative Riva Tnt2 32Mb video and first published at Keith's Virtual Helipad dec/2000, that can be used up to FS2002.
I might be uploading the files later, when I figure out how to move and do so on this site. I tried to upload an image  to post and went quite weird and lost windows before copying the code, have not idea where the image of chopper ended, just in case the file is Wh2k02B_02.JPG. will appreciate any guidance on this regard and to add an image to my profile.
By the way the credits on the FS98 Helicopters download page 15 do not mention my first name: "Wilfred" and my last name is "Sanchez Chicco".
Cheers. Wilscco
