It's been a while.....but i'm here now! I've been thrashing my head against the wall trying to think of something cool to build the for the fast approaching Arizona Electric Festival. I think I've finally come up with something worthy of blogging.

So without further distraction-I present project: "Thunderbird".
It's a take on the German WWII plane code named "Silverfish". Silverfish was a Nazi space plane designed to drop nukes' on America, so it has to be cool...right?! So anyways, some general specs.....

Motor average thrust: 54N
Burn time: Approx 1.8s
Guestimated weight: 10oz RTF-Loaded. After burn out- 8.50oz

Build Material: Mostly 6mm depron foam- carbon fiber main spars, 0.125" balsa Tail feathers with carbon reinforcement.
Airfoil: NACA 1210, 1.5 deg washout, 0deg Dihedral/Anhedral
Tail airfoil: Flat plate- rounded leading edge
Servos: E-flite S60J

The Thunderbird is coming along quite nicely, I have the wing sanded (very tedious and painful), the rocket tube layed up on an aluminum mandrel, all of the Balsa wood parts cut out, the hinges and rocket motor selected and ordered, all brand new radio gear sitting on the bench ready to be installed and all of the plans cut out! now to find the time to finish this all before Thursday morning, which is when the event starts (lol)


Here is a pic of a wing half- Note the 'snow' in the shop
