I'm looking forward to it myself! I emailed Topflite about the tailwheel info and possible ship date .

I was told:
" The date that I have is 8/11/06. I can not say if the date will change or not. If it does change Tower Hobbies will update the information."

And on the tail wheel info:
"On our prototype the tail wheel that we used is the #121 (ROBQ2210). The servo that we used is the FUTM0035 it is a car servo but it works nicely. If you do not want to use the same servo be sure that it has at least 90 oz of torque.

The main gear is ROBQ0536 and the air vale kit is ROBQ2302."

I hope this helps. I have the mains and air tank kit from Tower. I could not find any retract tailwheel information until I emailed Topflite.

When I spoke to Robart they stated they shipped the entire run of Mains to Tower.
