Quick question- Super Tiger/Thunder tiger
I need a new engine for a 13 lb scale B-2 model "yes the one in the special issue of Model Aviation". I've come to love my TT46 in my GP Tracer and was considering the TT61 from Tower $100. I guess TT doesn't have a 90 size but I noticed in Tower that Super Tiger does have a 90 for $120. The ST90 will give me .7hp more than the TT61 and weighs just about the same. Do Super Tiger users have the same love for their engines that TT owners have? I like O.S. too but don't want to spend that much $$$.
p.s. In the picture it looked like the muffler on the Super Tiger can rotate. Is this true?
