Hey guys.  Just wanted you all to know that I plan on building the Tiger 60 with a Magnum 91 4 stroke.  I emailed Tower because I I had heard here in RCU that it has a retract option, but I could not find it in Tower's catalog.  They emailed me back that that option was not in production anymore....but they would send me the instructions if I wanted them.  Of course I said yes. I recieved the instructions today along with the parts list in snail mail.  Tower is a great buncha people.  I will buy the plane and start building in late August.  I also just got a digital camera today so I will post pics as I build it.  So.....if you wanna retract the Tiger, just email Tower for the instructions.
