This ESC is simple to set up, especially when using the programmer card. I did have to re-program it one time, for some unknown reason.
However, I was quite disappointed when it burned out last night. I had it on a 48" Zagi, with a 3S lipo, and a Turnigy B2835-2700 and a Master Airscrew 5.5 X 4 prop. It flew well - plenty of thrust, but only lasted about 6 flights or so :-(

Using this for 18 months in a Mini Pulse with a KD A22-20L, and 3s 2200mAh - very happy, never had one issue. It is amazing, the plane saw lots of rough landings from my 7 years old student, 2 big crashes that sent the plane for total rebuilds, but the electronics are working just fine. Very happy with the choice.

I bought this controller for my .25-class models. Great combination with Turnigy 35-42C 1100Kv. Peaks at 45amps - only small rise in temp. Usually fly at 10-30amps where it is cool. I use 4 micro servos BEC peak at Which I'm sure you know total 1.5amps can use with larger servos. Will definitely get more of these. With the motor TR-35-42c-1100 rpm and a blade 11x5 set adapted to these models. Very reliable even when using extremely mild in most it can also be used as a controller for helicopter having the function of the governor system maintains constant main rotor rpm. I recommend it for the low price and of course for its excellent performance.

This a awesome speed controller only wish they had the 30amp also for smaller applications like the Bixler plane. Would never fly again with out cells being monitored, can't remember the last time my batteries went puffy.

I finally got my helicopter in the air. I've got this ESC with a Typhoon 2215motor, 3 HXT900 servos, a N590 KDS tail servo and a HK501B gyro setup. This ESC is a must for a 450 heli setup especially if you want your batteries to last longer. The direct cell monitor, monitors each cell individually and as soon as one of the cells reaches the set point the ESC slow down the head speed which means land now before you have to auto rotate to the ground. It does give you enough time to bring it in and land it before it slows right down and stops the engine. With the typhoon 2215 motor, timing set to medium and a 12tooth pinion I am reading a optimum head speed of 2850rpm with a lot of torque for 3D or aerobatics.

I only have one suggestion for this product, the battery monitor cable should have been at least 2" longer for better mounting options, but I did manage to connect it to the battery will increase the cable's length at a later stage. As us heli pilots know by this stage the battery normally goes flying through the windscreen of the plastic canopy and would pull this cable with if the connector is not properly mounted. Thank you HK
