I love the Reedy Sonic. I own the RevTech, Viper, Speed Passion, and LRP X12, all in 17.5's. I prefer either the Reedy or RevTech motors. The reedy has a little more torque then the RevTech in my opinion. I try to run them as cool as possible just for the simple fact I don't want to replace them. The motor would come off after a 6 minute heat at 110-120 geared at 33/75... My timing on the can is set two marks past 0 and I am running Blinky on the ESC...
