What happened to the Viper idea?[

The Viper would be faster but I have always liked the Sundowner since it has been out. I talked to Dub jett and he is building one for his friend and thinks it will have good results. I was wanting to see how it turned out before I totally made my decision. Its pretty bad when you buy a Engine and try to figure which plane to buy for it. Its ussally the other way around I really like the Hanger 9/ E-flite planes. I have always had good luck with them. I wish the Sundowner was alittle smaller/lighter like a 50-55 inch wingspan and 3-4 lb weight. I guess you cant have everything you want. haha Im thinking the plane will do over 130 striaght and level. I radared the Pulse XT with my .55ax/ 10 x 7 prop and it done 105-109 straight and 133mph in a BIG dive. I was pretty happy with that. The Ultra thrust pipe seemed to gain 5-10mph. It went from 12,900 to 14,600 on a 10 x 9 prop with the ultra thrust.
