Hi Friends,
ESC 45-50 amp (45 gm weight)
http://www.hobbyking.com/hobbyking/store/uh_viewitem.asp?idproduct=15442
Is it having any programming option ?
Safe to use with almost any motor with Max Current of motor below 50amp?
Any drawbacks?
Will this ESC work with :-

The description says " limited range of programming".
This ESC will be over kill for your motors, except for the first one. You can easily use the bottom four motors on a 30A ESC.
Hi Snehal
The ESC has limited programming ability but donno wat all can be programmed... and also it states not to use motor above 2200 kv
so dont try to use this motor, http://www.hobbyking.com/hobbyking/store/uh_viewItem.asp?idProduct=12919
the motor may err on the rpm limits.

Motor and the load Kills the ESC and and Not ESC Kills the motor...
Its all messed up.i am a begginer. Sorry
i want to use 2200kv motor as well as 1000,1050 kv motor.
2200kv for F-117 and 1000 or 1050kv for Airtruck.
i havent bought anythig yet.
And i want to invest my money in one esc only .So what to do?

i meant over kill = "An excess of what is necessary"
@snehal
The one ESC for all plane thing never works out, better get two different ESCs.
i dont think so...the esc will supply the amount of current required by the motor if the motor ets above the capacity of the esc ...it will fry off... else it will run cool
;D
BTW I am also thinking about buying the 2200kv motor, if only someone can confirm it can run a 6x4 on a 40A ESC. Thats the biggest I have.

akky! I know all that man. i'm talking about weight. How many guys have you seen flying a 15A motor on a 45A ESC.
So what i am understanding that 50A can be used for all motors below 2200kv but the drawback is its weight.
@sunlikestar but weight of HK 25-30(programmable) is 40 gms.
and Hk 45-50 amp ESC is 45 gms.
sooooooooooo....????
i have :giggle: :giggle:
plus its not the KV which decides the
esc...it the wattage and the power a motor draws
So which ESC for 2200kv motor. (not that innerunner). Suggestions plz ?

HK 25-30 is only 24 grams.
I use this one http://www.hobbyking.com/hobbyking/store/uh_viewItem.asp?idProduct=13429 its 28 grams and still considered heavy.
See there is no big problem using a bigger ESC on small motors, but very soon you'll get fed up of swapping ESC and will want separate esc for your plane. So you better decide what motors you want to buy and buy one ESC for each current range. For the motors you have listed above 25-30 and a 45-50 ESC :thumbsup:
F-117 is not for beginner, so be very careful, i think u should built other one, hav lot of practice and then go for F117.
as sunlikestart has mentioned, using same ESC for 2 plane will never work out!!!!!
better invest for ur 1st plane and once comfortable go for new setup for F117
Ashish
Thank u very much Guys.I am going for Airtruck or FPV plane from mickeys rc with motor 1050kv with 25-30 HK(programming).
is it fine?
I will later go for F-117.(coz 2 reasons ,its motor and it is not for begginer).
Which one is better? why?
http://www.hobbyking.com/hobbyking/store/uh_viewItem.asp?idProduct=6458
(why this one says 25-30A and not simply 30A??)
or
http://www.hobbyking.com/hobbyking/store/uh_viewItem.asp?idProduct=13429
(can be used with 2-4 lipo and less weight)
which one has advantages in programming?
Hi
I still dont understand y u still struck with programming? u dont require any for a beginner airplane.
The lower Amp rating gives u how much of continuous current go through the ESC and the higher rating for burst current( wen u suddenly give full throttle and come out from a nose dive)
selecting a motors in not jus looking at Kv ratings... u have to check the power rating and prop size.
i've actually used this ESC but a 40A one http://www.hobbyking.com/hobbyking/store/uh_viewItem.asp?idProduct=13429 and found it to be nice
http://www.hobbyking.com/hobbyking/store/uh_viewItem.asp?idProduct=15442
I found that weight is less than all 30amps ESC.
Inbuilt BEC 3A
Can be used for all motors below 2200kv motors. And also for 2200kv but burst should not be used as precaution.
BUT suppose 1000kv motor the throttle should be 30%.And if accidently the throttle is increased above half,the ESC will fry. AM I CORRECT???
hmmm.... burst current depends on ur motor and prop combination, may i know which motor are u gonna use?
u will fry this ESC only if the current goes above 50A
and the current will go above 50A... if accideltly i will push the throttle to how much percent??
http://www.hobbyking.com/hobbyking/store/uh_viewitem.asp?idproduct=5690
i have ordered this one.
It depends on the max current rating of the BLDC. For example the A2836-8 BLDC has a kv rating of 1080 and max current rating of 22A. So you can safely use a 30 Amp ESC. And, as far as I know, there is no maximum throttle % rating for a given kv rating.
Vivek, correct me if I'm wrong.
@snehal
The motor's burst current capacity is 23A, full throttle will take 23A current (at burst) and it should be less than 10 Seconds.
@ swapnil
U r right nothing like a throttle limit for Kv rating and all !
Man,
Safety comes from Burning. and burning comes from overload (Mechanical).
So, from Motor's point of view, watch it's prop size and loading (Watt/weight of model).
You can choose smaller dia or lesser pitch for lower loading with RPM. Similarly, AIW should be less than recomended.
From ESC's point of view, Choose the capacity that can be safely supply the max current.
And not but least, check the battery max current limit (AH Capacity x C capacity)
Please keep 2-3A relaxation of normal current for servo and dont go for max discharge capacity. It may reduce Rx voltage and link can be broken if separate Rx Battery not used.
Motor is an electrical item and ESC is electronic item. Electrical items can withstand overload a little bit but electronics dont ( if not safety factor already designed.) .
And some basic equation will always help you working with electric setup.
Watt = Volt x Amp -------- (You can get motor watt or current).
AH x V = Watt x time -------(minimum Flight time with full charged setup)
And happy flying without burning.

:headscratch: :headscratch:
Kalyan,
Do you mean that overload results in increased safety?? This is very contrary to all engineering beliefs! :headscratch:
-Ismail
I am very much confused
Please help me in selecting ESC
currently my motor is
http://www.hobbyking.com/hobbyking/store/uh_viewitem.asp?idproduct=5690
Weight is almost same for these ESC
Which one to choose Turnigy or Plush?
Why not 45-50 amp HK if it can be used safely for motors below 2200kv and weight is almost the same?
http://www.hobbyking.com/hobbyking/store/uh_viewitem.asp?idproduct=15442
http://www.hobbyking.com/hobbyking/store/__2164__TURNIGY_Plush_30amp_Speed_Controller.html
http://www.hobbyking.com/hobbyking/store/__13429__HobbyKing_30A_BlueSeries_Brushless_Speed_
Why not ? :)
All those ESC's are fine.... choose any one!
Order which is in stock HK takes quite a long time to replenish it.
Someone said that that 45-50 Hk ESC is not good ? I dont know why.
I dont want advance programming but want basics.
ANYONE USING THIS 45-50 HK ESC . Please Share your experience.
A 30 amp esc can be used upto how many Kv's motor safely.?
