Hi,

You may use the ch. 6 Aerobird Challenger Fuselage.
You can get it from your dealer, or at horizonhobby.com
The part # for ch. 6 is HBZ3546. It is in stock.

The original Aerobird fuselage is also in stock. HBZ6046
So, There are TWO parts in stock you can choose from!

If you are having technical difficulties, please send the entire product with Tx back to HH service, and I am sure they can take care of it.

Best Regards,
David
