Gordon- FYI I have sent Bay turbines an email re- their hydrualics and SU27 explaining the interest in their system for the MIG 29, being the weekend still! I will wait a few days for a response. There does not appear to be much mention of the SU27 and its systems on the Bay site, so I am pressuming the SU maybe a prototype. I hope to hear back from Bayturbines early next week? stay tuned.....
