There's actually a group of people working on a vtol kit. Sorry, but I can't find the link now. Click on this link and scroll towards the bottom of the page. There's a video of a home made vtol, featured in MAN a while back. [link]http://www.radiocontrolzone.com/plane/video.asp[/link]

I found the link I was looking for, but its not an Osprey. Predicted available in 2005. Priced at around $1000-$1500US. Here's a small thread about it [link]http://www.rcuniverse.com/forum/m_1339382/mpage_1/key_vtol/anchor/tm.htm#1339382[/link]
