LOL. FAA requires a cutdown device--actually two. I was talking about a valve. Might have to expand my $10K budget though. Need gas money to chase it to the next state as it cuts through the jet stream. As I recall, there is a jet stream trough over NM most of the time, though. If Baumgartner can do 128K, surely our little scale model could hit FL650 and give us some data and bragging rights. Thanks, SG! VR, Indy.
