Help!
Having a tough time finding a brushless motor for my EasyStar

I am looking for a brushless replacement for an Easy Star, and I am having trouble finding one for less than $50.

I know this question has been asked for years, but times change and answers in threads from 2007 and 2008 no longer apply. I have done a LOT of searching on this question. The HXT 2835 appears to be the perfect choice for an inexpensive drop-in replacement, but it doesn't appear to exist anymore. There are E-Flites and Great Planes motors available, but I'd rather not pay $30 for a brand name sticker applied to a $30 motor.

At this point, I could go either inrunner or outrunner with a mounting mod. Can anybody suggest any motors (and matching props) that are currently available? I would really appreciate it!

I was going to say Eflite Six Series but you already made your point about them.

Try HeadsUpRc.com he had a 2835 Inrunner last time i looked at his site.

Thanks for the replies thus far. That Emax motor looks like a perfect match.

I am still continuing my search, mostly through the myriad of EasyStar build threads on the net. I just ran across this little motor that only costs $7! It is a TowerPro Brushless Outrunner 2408-21 from HobbyKing (http://www.hobbyking.com/hobbyking/s...idProduct=4321). I'm not normally this cheap, but there is something appealing about getting an EasyStar in the air as cheaply as possible. Sort of like Spirit and Opportunity.

Cheers.

You did see they recomended a 8x4 prop.
Plus it is also an outrunner so you will need to come up with a way to mount it.

Yeah.. heh. And it's out of stock as well.

I'm new to electrics, but it appears that this brushless outrunner might work... and it's in stock and priced right. D2822-141450 - D2822/14 Brushless Outrunner 1450kv (http://www.hobbyking.com/hobbycity/s...er_1450kv.html) perhaps with a 7x4.5 prop.

I would say, again, the KV of this is a little low (I'm assuming you are going to use 3s 2200s ?) and I feel, you are making work for yourself using a brushless outrunner in the EZ*. I believe Heads Up has a good reputation and I agree that 2836-24 looks like a great match for the EZ*. I have three EZ* and all with Inrunners. I haven't used this motor, but it looks good to me! Good luck with what ever you decide! Terry

I had this same problem when trying to source motors for my Twinjet...for which I had similar priorities. ~2000kv, 28mm, cheap.

That Emax motor from Valuehobby is ok by many critera...and it's probably a good enough qualiy motor but it's heavier than it needs to be at 93g. The EasyStar can handle the weight...but it's a bit of a waste, IMO. I think you would want to stay closer to 75-80g if possible.

I ended up biting the bullet and going for some nice motors...because it IS really hard to find a light, inrunner, 2000ish KV that doesn't cost a small fortune.
http://www.lightflightrc.com/ ARC-37-28-3 would work amazingly well with a 6x4 prop on 3s....but it's $60

I used a A2212/6 http://www.suppomodel.com/ on my (cough...ahem...) son's Easystar. The easiest way of attaching it is to take an old brushed motor and remove the guts from it. You can now screw the outrunner to the empty can, although it's a bit fiddly, and glue the that into place (or zip tie etc). You can either leave the outrunner over hanging slightly (check your prop clearance), or remove a small amount of foam to allow the outrunner case to spin freely and push the empty can in a bit further. On a 6x4 prop, 3s 1800 20c it pulls about 28a. But it's too quick for my son, and a 6x3 may be better. It's also a sweet motor on a 5x5. The Suppo 2208/12 (1800kv) might be a 'calmer' choice of outrunner tho.

Try a Micro Jet Motor with a 6x4 Prop. It's lighter than an inrunner.

This I do have! This is the best combination I have! You end up with a hot EZ*! I believe I got mine with a 30 Amp.ESC. They are great people to deal with! From my experience, they are very good at backing the product as well! I believe I have 50+ Hours on this motor. Terry

It's helpful to at least give an indication what country you are in so appropriate sourcing recommendations can be made.


Assuming you want to run 3S power, here are a couple of inexpensive 28mm inrunners of 2200kv:

Hi Guys,

what do u think abt this brushless, which one would be better for the EZ?

Turnigy2836 brushless Outrunner 2350kv

Turnigy 450 H2218 Brushless outrunner 2500KV

KD A22-20L Brushless Outrunner Motor
