Great as usual.
If you are reading this is because you thinking if this is your right choice. YES! this is a great ESC! It comes WITH a cooling FAN! This ESC (Electronic Speed Controller) has many great options but you need a LCD-program box to program it. (it is NOT programmable via Transmitter) Car/Airplane AND different helicopter modes especially the "Store Governor" (an electronic constant speed controller ) for 3D flights. Also possible to check relevant data after flight (max temperature/voltage) I strongly recommend you to purchase a LCD-program box. (it is also a lipo battery tester). for the maximum use of this ESC. You don't need a separate battery for your receiver the SBEC function is built in. After a 3D flight with a 700 class helicopter this ESC was cool. cooling fan is included, LCD-program box is NOT included. After your first experience with this ESC you want it in all your models. You get what you order from this company! no doubt about it! IT is what it is!
