Along with the KEDA 190KV motor, 24V 15A p/s, an $8 motor tester,
runs the Clarke Mini Lathe very very well.

I am so disappointed about this product, I buy it about having gov function.
I calibrated the gas and I have made several flights with auto timig and auto degred and 8khz and 6º
heli has no power one half of the previous esc,, even got a whiff of burnt engine,,, I have removed it and put back my old Turnigy plus and go back to perfect the engine ...
estoy muy decepcionado con este producto, lo compre por tener función gov.
he calibrado el gas y he echo varios vuelos,con auto timig y auto degred
el heli no tiene ni la mitad de potencia que con el anterior esc,, incluso empezó a oler a quemado el motor,,, lo he quitado y vuelto a poner mi turnigy plus y vuelve a ir perfecto el motor...

Just sent back the unit to get a replacement. It is everything HK claims it to be. I used it on my Align 450SE V2. I worked as advertised for about 8 months. But then I broke a tail rotor link and decided to rework the Heli and do a complete rotor head alignment and replace the main motor. After the rework, I used a YEP program card II to finalize the rebuild. After programming the RS 45A, it lost all power regulation to the main motor and BEC. I had either no power to the main motor or full blast power on. For some reason, it also affected the aileron and pitch channels. I tested the Rx and servos without the ESC and they worked fine so you got me how that happened. Other than that, I thought it was a great ESC with a lot of features. If you buy this ESC, I highly suggest you also get a programming card with it as it comes with no instructions on how to set it up with the Tx. Happy hovering!

good esc for the hk450 heli but it is a little big.
it doesn't even get warm with a typhoon 2215 3550kv motor at 90pcnt throttle using a 11T pinion.
it comes pre programed for heli use and the soft start is nice and slow and fluid.

At this price, a perfect controller for my 450 Setup - easy to install with the RC-Setup (from the YEP Controller) or better, more convenient and to be attained all functions (ex.Cov.Store, Softstart Speed and more) with the YEP ProgCard.
He has a very smooth Softstart, in my Setup (3450kv/3S2200 - Startup Power 2pcnt-Proged with Card), with full cells (4.2V): to 60pcnt approximately 25 seconds to 80pcnt app. 30s
Speeding from 60pcnt to 80pcnt needs about 2 sec.
(measured only with my cheap wristwatch).

The previous 15 flights he worked very well, within my flying style (round trip, soft 3D) the Gov. has no speed drops and I see no problems.
It looks like a YEP in another heat shrink but he has also installed "Anti Sparking!
