Great ESC. Performs as advertized. I now have 9 of them and am extremely happy with all of the Hextronic Pro's I have purchased. The ability to use the USB to configure and actually run the motors is a great help in setting up the right prop.I use it on my T-Rex 450 XL with a 450 TH outrunner. No problem, soft start is OK. I also use HXT900 9g Micro Servo and Lipo 3s1p 2200mA. That's a cheap set fun to fly about 12 min.Its a lot cheaper than other options and works just the same. I have used this esc with the heavist pulling motors such as Medusa and have no problems. Programming was flawless.the Hextronik product are very usefull end hight quality. Lipoly and controller are all very wellThis speed control is easy to program and has alot of programing options. I have used it a few times and think it is a very good value if compared to other name brand controlers with similar featuresI was used to CC escs but this esc has same options and performs great for a fraction of the price.With USB link and a notebook i can change settings in the field :).
