I am now long since retired and ready to get back in the airplane business.
Barry Jay at TAF tells me that my entire kit order won't be coming for a while so I have settled for an empennage kit that is coming in February

I am really impressed with the Sling TSI and am looking forward to the build. By the way, I have a 40 X 40 X 15 foot heated and air conditioned shop
where I have been building large 1/4 scale RC models for about the last 6 years. I have been modelling for the last 70 years, now time to build a big one! I am being assisted in this effort by my oldest son who is an Aero engineer and by Oxley who is a member of this forum.
Promise to not be a pest but I hope I can call on you guys knowledge from time to time.
