I've seen the SWB Mamba at various jet flys starting at Flordia jets 2003 where Bob Violet was flying it in his P80
I have also seen it at heart of ohio and at the last Superman flyin where it was flown in several types of aircraft, the most impressive
was a BVM Bobcat XL the (larger of the two bobcats) it was staying right in there with the larger turbines in the 20 lb class (very impressed) also what I learned was that the fuel consuption is only 6.76 oz/min @100% .

Good luck and Merry Christmas
