Hi Guys,

I was going to upgrade my easy star to a brushless..

Can anyone please recommend me a motor and esc ?

I was thinking of this motor - 2200kv Brushless Inrunner & i have a brushless 18 amp esc will that work with this motor and the battery i have is Turnigy 2650mAh 3S 20C Lipo Pack ?

Can anyone please help me out here..

cheers

hey atul bhaiya
if the motor u are using is the same as this

then its a go ahead for you

before you fly just ask prady uncle to test fly it

I found my old post where I wanted to convert my easy star to a brushless setup... :giggle: :giggle:

Finally getting to it as time permitted.... ;D

Using a 2200kv brushless motor, 30amp turnigy esc, 9gm servos, 2200 turnigy 3s 20c battery..

Right now just soldered everything to its place..I guess will put on the motor tomorrow..Did some spray painting  :giggle:

Will get all the stuff in the bird by today..anybody's got a 6*4 prop & a prop. calculator..looking out for an excel made sheet or something that would easily calculate the prop. required..

Hi Atul,
as far as i have seen the easystar, i guess that there is no extra space to put a prop bigger then 6x4. if you want to use bigger prop then you have increase the height of motor mount from main fuse......

Morning Sandeep,

yes you are perfectly right..I don't want to put in a bigger prop. I was just looking out for a prop calculator for other builds..

hey what kind of paint is it ? can you share what kind of equipment/setup have used !

Its just normal spray paint cans..you can easily get them in the market for 100rs or so..

The equipment I have used is as follows -

motor - http://hobbycity.com/hobbyking/store/uh_viewItem.asp?idProduct=5203&Product_Name=HXT_2835_(380S)_2200kv_Brushless_Inrunner

esc - http://hobbycity.com/hobbyking/store/uh_viewItem.asp?idProduct=2164

battery - http://hobbycity.com/hobbyking/store/uh_viewItem.asp?idProduct=8932

prop - 6*4

and 2 normal 9gm servos..

no i was under the impression you had a proper spray painting setup like compressor etc.

thanks

sahil

ohh..no dude..I would love that maybe in the near future..In btwn that would be costly right ?

i don't know it might be, even i want to try it  :'( we should find a low cost solution   :help:

some thing to start with

If its on e-bay for that cost then those guns would be rather cheap outside in the market...need to find out locally..

The upgrade is DONE.. ;D  ;D

I have successfully completed the brushless conversion..check out the pics..

thanks

This diwali weekend, after more than 10 hours of flying in 3 days the permax 400 on my easystar blew up both its brushes. So can you recommend me locally available brush less motor and ESC. I am also ready to cut the foam motor mount and put in a hand crafted mount. In the mean time i am hunting for a permax 400 motor so that i can have some flights this week end.

Sun like star. EasyStar is too excellent plane to mess up with. Get the Turnigy outrunner Atul has mentioned above. I used exactly the same setup to upgrade my Friend's Easy star and they fit so perfectly as if made for EasyStar.

Please stick to a similar size (not just in power but also dimension) motor instead of modifying the mount.d

i think you meant the inrunner Atul is using. doesn't look like its available locally :(
BTW santosh just said that he will give me permax 400 motor for free  :o :bow:

My intent was to covet you from  outwardly modifying the plane for whatever motor is available locally, instead have patience and get the appropriate motor (original Brushed/inrunner brushless) from Hobby King etc. Not many LHS Selling Inrunners anyway.

Its great that Santosh has offered you the motor. You can get 20-30A Brushed ESC from RcforAll if you have your ESC fried too.

Cheers.

ok, looks like i am ready to place my first order to HK. thanks ujjwaana.

Go with an 1800mah instead of 2200mah..

Atul, if you have upgraded to the Turnigy brushless Inrunner, 2200mAh would be better than 1800 - both CG and power consumption purpose.

SunLikeStar,
Better follow the EasyStar Fan page for more details before ordering. I could be wrong as I have used this setup for static test on my friends Easy*.

i am placing an order for
Motor: http://hobbycity.com/hobbyking/store/uh_viewItem.asp?idProduct=5203
ESC: http://hobbycity.com/hobbyking/store/uh_viewItem.asp?idProduct=9483

which prop and shaft adapter should i take??

You are tack right on the motor. But people have reported that this gulping as much as 23AMP. So you better use a 35/40AMP ESC instead of 30AMP. I some how follow rule of having 1.5x larger current capacity ESC.

6x4 Master Airscrew/EMP Sports Prop would be apt. Dont go for GWS as they are no good for high speed (>1700kv) motors.

you would need a 3.2mm Grub Screw Prop adapter. Though the the shaft was exactly 3,2mm as on my digital caliper, I had to sand the prop a bit (by putting steel file on rotating shaft under power). So don't get paranoid if 3.2mm prop adapter doesn't fit first.

Get some 30/35mm Heat shrink and cover the the motor with that before gluing the motor into the Foam Motor mount in the Easy Star. It giver better grip and you can easily remove motor, if either of the motor or Easy* is destroyed.

Ujjwana - 1800 mah would be perfect fr the CG and will fit in the easy star cockpit.

I agree with the prop adapter.. You can get it locally as well..

I found the 30amp esc to be sufficient .. since its not in stock go fr 40amp.

Sunlike star - If you read some reviews below the motor specs you will get a clear idea of what to buy. Make sure you secure the motor properly on the Ez *

We will catch up soon anyways..

Thanks to Ujjwaana and Atul, my first easystar brush-less conversion went pretty well.
Now that my new EZ is on its way home, I am thinking about putting an outrunner to it.
The thing is I want this one to be a light weight slow flyer which can haul a sony cyber shot. My current does the job, but gets quit heavy and fast. I am thinking about putting and <50 gram ourunner saving me around 60 grams. Also with a small outrunner i can replace my heavy 30A ESC with a smaller one saving me some more. Plus i am willing to put a custom motor mount to facilitate a 7 inch prop.
Any recommendations for the motor?

I am thinking about these motors

Guys,
Very soon I will be converting an EasyStar to brushless.
SunLikeStar, Did the HXT 2835 (380S) 2200kv fit into the stock mount/space ?
How was the power ? was it just OK ? or a little overpowered ?
I intend to carry a small payload of camera and electronics so need something that can haul it all up

Atul, would also be great to know what you used for yours .

Thanks
Gaurav

Hi Gaurav,

I used this setup as below -

motor - http://hobbycity.com/hobbyking/store/uh_viewItem.asp?idProduct=5203&Product_Name=HXT_2835_(380S)_2200kv_Brushless_Inrunner

Esc - http://hobbycity.com/hobbyking/store/uh_viewItem.asp?idProduct=2164

Prop - APC 6 * 4

Battery - I would say use a 2200mah or 1800mah. You can try both to correct the CG.

and this above motor is a perfect fit for the easy star. As if it was meant for it :D

Its an awesome fit!! I use the same motor with a different brand name, but its the same. I am sure it will give you enough power to haul your electronics, I think upto 300 grams should not be a problem. The only catch is that as you are running a small prop you have to throttle up to get that much power, which makes the plane go very fast.
Thats why i am thinking about raising the motor mount and running an outrunner with 7 or 8 inch prop.
If you dont have a heavy payload then the 2835 2200Kv runs like a dream. You can fly slow fast vertical, what ever you want.

Ordered TR 28-26 1650Kv Brushless Outrunner (http://www.hobbyking.com/hobbyking/store/uh_viewItem.asp?idproduct=5655) and SF E-Prop 7x4 Prop (http://www.hobbyking.com/hobbyking/store/uh_viewItem.asp?idProduct=9840). Will post result when the motor arrives.

The motor and prop arrived yesterday.
PFA pic of the motor attached on empty can of a permax 400.

My easystar with a new power plant, more power on half the current and still 50 grams lighter than my previous setup :)

I tried my new setup today, the plane is definitely flying much better than before, more thrust at less speed.
Only one problem, even tho i have not timed it in any way but i didn't notice any major improvement in flight time ???

((My easystar with a new power plant, more power on half the current and still 50 grams lighter than my previous setup ))

If you are using the same battery then you should get more time, if not double.

thats what i was expecting, i am planning to time it properly tomorrow.

I love how the plane flies now, almost like  pattern flyer and if you want to glide; just go WOT for 30 seconds and the EZ will climb up to thermaling height, previously it used to take more than 1 minute for that.
But still not sure about efficiency of the motor. Is there any way i can do a static test without a watt meter or ammeter ???

What is the voltage the battery , type and capacity?

Jitender

3S 2200 mAh lipo 25C.
I think I have sorted this out. I did 1 minute runs with both setup, each time recharging the battery and checking how much charge i am putting back in the battery. After doing multiple tests i found out that at WOT this setup is 50% more efficient and at half throttle it is 30% more efficient than my previous setup. Very happy and satisfied by the results :)
