When I got into electric models I was looking for good equipment that was cheap. Nothing against Cobra and Badass engines, Castle and Jetti ESCs and active timer. O just think they're expensive for entry-level models.
I'm using a Hobbyking 3536 (2820) SK3 motor in my electric Flitestreak, which is a good performance motor for a reasonable price.
For the ESC I was using a 40A YEP/ICE which has good features such as soft start, braking, freeweling and Governor with good results for sport models.
I recently bought 2 40A ZMR ESCs with BLHELI firmware with Governor high, P-gain, I-gain, soft start, break for 14 dollars is a really bargain.
If a 14 dollar ESC can replace a 70 dollar one, certainly not, but it could become a good alternative for sport planes.
