RE: model tech mach racer
I have a ST .45 with a t/pipe (maybe not tuned good yet, this is my first try) 9X7 APC, getting a little over 16,000 on the ground. Flies ok I guess, manual suggests not diving at full throttle, I guess things might blow apart (flutter!) I like how it slows down to land, this is my first delta. No radar or speed guesses, but I figure it's a little over 100mph? Nothing like when the ST was on my Viper (Jett muffler) turning the 9x7 over 17,000, that was fun...
