On RCU there's a long thread about a turboprop RC plane that uses a variable pitch prop. It's similar to what's used on helicopters and what allows heli's to hover upside down. </FONT><FONT COLOR="#000000" style="BACKGROUND-COLOR: #ffffff" SIZE=3 FAMILY="SANSSERIF" FACE="Arial" LANG="0"><BR>

Hanno Prettner did that in the 70's when model heli's were barely able to hover. Then Steve Helms did it in this country around '81 I think. <BR>
