Whack off the nose and rebuild.  Or see if you can move the battery back (I dunno if that's in the cards, use your judgment).

Next time, move the wing forward in the fuselage.  Banshees are made to work with unmuffled Fox 35's, which are pretty darned light.  They also tend to have a fairly short-coupled tail, which was popular back in the day but isn't how it's done now.  Increase the area of the horizontal stab by 20% or so, and you can call it a "Fancherized Banshee".

Are you sure you're not using way too much motor & battery for the plane?

So, I also have to lengthen the tail or make a whole new fuselage, now I feel worse (lol).  How much longer do I make the tail?

No no no!  You have to get the dang thing in the air as expeditiously as possible.  Then you can start thinking about what to do to the next model (assuming there's another Banshee in your future).

A Banshee will fly just fine with a stock tail length -- it'll just fly better with a longer tail.

Cut the fuse and move the wing 2 inch forward. I did this before I built the wing.

Thanks for the number but the wing is already glued in. I just built this plane so I could prove you can put a battery box on center in the wing and not have it fold. I'll just shorten the nose and add tail weight to trim it if I have to.

Thanks,

I cut 2 1/2" off the nose of my electric Banshee.  Wing set in normal place.  C/G is 2 1/2" back from leading edge which is about 1/4" forward of the plans.  Battery box was mounted on wing to get the C/G desired.  After all that, the plane flies like a blimp and I'm not smart enough to figure out why.   
 
Please keep posting on this build and how it flies.

Be more specific.  What is total weight ?

Weight 48 oz with battery.  Engine is an Arrowind 2832/05.  Motor running about 85% and doing 5 1/2 second laps.  Plane very sluggish and erratic behavior.  Will  do a loop but extremely large.  I have changed the motor thrust angle but haven't gotten a chance to try.  Any help appreciated but don't want to hijack thread.
