Beanie, here is the way I did my flying stab. It's how I do all my flying stabs. The vertical stab is thick (maybe half inch) where the metal sleeve is at. It's hooked up to a servo and it feels real strong. It barely has any play in it.

This may be a bit optimistic, especially considering how long it took me to get this far, but I think I might get it in the air by next weekend. Really all I have left to do is add the motor/esc, make a battery tray and skin the bottom, then fly!

Thanks guys.

Done with working on the panther for today (I think). The nose still isn't perfect, needs more sanding.... It's coming along nicely, I loooove the curves on this bird!

Thanks Walt.

Anyone know a rough idea of where the cg is supposed to be? I need to know before I make my battery tray...

not really... that's why you're the beta builder! you can ask J or CN where his CG was and that should give you a good starting point.

So is the motor going to be mounted at/in the exhaust nozzle or on the tail? A prop slot would be required for an exhaust mount and I imagine the tail would need some reinforcement since it will take a lot of the aero forces generated by the elevator.

osprey- yes, you're right, the motor is designed to be coming out of the exhaust port. a notch will need to be cut into the fin. the fin is double thick and has either balsa LE reinforcement x2 or CF. its a pretty short stubby fin, so i'm not worried too much (unless a massive prop is used).

I don't think a massive prop will work John had to cut his just to get a 7x5 in there

Thanks Bob.

Some more progress made on the Panther. Mounted the motor on it, I'm using a Grayson hobby super mega jet. Made a canopy in the meantime, it will be glassed then pulled for a clear canopy. I think I'm also going to make a pair of wing tanks to go on it, I think it looks so much better with them.

The more I skin it and look at it the more I realize how big it really is. Can't wait to fly it.
