  • cant beat the price

    posted by dragonsfire

    Great motor, and cant beat the price. I ordered 4 of these, and none have the defective bearings other people are talking about. They are fairly high powered and relitively quiet. I was using them on a quadcopter until one ESC died, and now i am using 1 direct drive with a 10" prop on my slowstick
    It might be worth it to pick up a couple spare prop adapters at the same time, just in case
    I will most likely buy more in the future

    Contains:
    Two 35v 470uF electrolytic input caps
    5v reg TA7805F, max Vin 35v
    Atmel ATMEGA 8L
    LT1262, a 5v-to-12v charge pump, presumably to make 12v for gate drive
    Three IR2101S gate drivers. Uses floating high sides, the high side can go up to 600v.
    12x output transistors, 2x per half-bridge:
    In mine, 11x are FDD6688 (30v Vds, 84A, 5mOhmn @
    10V Vgs) and oddly enough ONE FDD8896 (30v Vds, 94A, 5.7milliohm Rds-on @ 10v)
    Cheap controllers often don't use gate driver chips. So this is pretty decent.
    The 5V reg is not well heatsinked. If operated with a high input voltage, if you draw a lot of current out of the BEC you can easily overheat the 5v reg. True in most of these.
    Absolute max voltage is 30V here, limiting factor is the transistor Vds-max.
    It sounds like it CAN go up to 6lipo (4.2v*6=25.2v). Just barely, but it can. Should be able to work on a 24V sealed-lead-acid battery too, but that could be 28.8V while charging, very risky. If the ESC isn't turned on until it's taken off the charger and left to rest a minute, it'll be FINE.
    Oddly enough, when both sides of the H-bridge are off, the transistor voltage breakdown rating is up to 60v, in which case the 35v rating of the caps and voltage reg are the limiting factors.
    I've never actually turned it on. This is an Aspie Tech Review.
  • Great ESC for airplane and mybe cars

    low price and high power with a good heatsink:75A continuous, drop at 50A at 100°C the cooling in fly is enough to void this , the internal resistence is low because use all n-channel fet P75N02LDG.Fast response during fly.
    recomanded for 500 watt brushless motor
    it is a good choice if you are beginner, good compromise between performance and price
  • Great littlle ESC

    posted by IACEI

    - Works very Well As Expected - Lightweight - Seems to be Good Quality - Way more resistant then most of the small esc that I tried, most burned because the Amps were over-rated- Fonctionne tres bien, rien a redire- Leger- La qualité est bonne - Beaucoup plus résistant que la plupart des petits ESC qui ne respectent pas l’ampérage affiché.
    Installed it on a Multiplex Fox on 3S and it works just great unlike a Red Brick ESC from HK.Je l’ai installé dans un Fox de multiplex et ca fonctionne très bien en 3S.
    If you need it, buy it!

    This looks like a high quality ESC with a good sized heat sink. The inbuild BEC is very good. I have run this ESC at 50 amps and it holds up extreemly well. At 60 amps it will need sufficient cooling otherwise it is getting too hot for my liking. Of all the 'Cheepo" ESC this is by far the best I have seen. A real bargain for the quality provided!
    I hate that I have to write 1000 characters when everything that needed to be said has been said.
    I will buy more of these!
