About to buy a motor and need help deciding what one I need!!!!!

I am getting a techone Extra EPP (on the way to me!!)

This one here

The question i have is will what one(s) of these motors will work? (if any)

This one: D2830-11 1000kv Brushless Motor

This one: Turnigy L2210C-1200 Brushless Motor (150w)

This one: D2822/14 Brushless Outrunner 1450kv

I need to place the order soon so any help is appreciated.

If none of these will work, can you show me one that will? (from HK that is)

Thanks in advance,

Jeffrey

I have had really good luck with the Turnigy L2210-1200.

Here are a couple more good choices:

If it were me, having to get a motor from HK, I would pick any one of these three.

Hope this helps.

Good to know!

I ended up going with the Lss10-122kv motor as it seemed to have great reviews and good power... "Thrust: 700g" on a plane with a weight of 400-500g I would think would give me pretty good power to pull out of a hover or any other thing I would want to do with it

I am thinking about getting this motor as a backup:

Seems like a beast and low KV so it can swing a huge prop for lots of thrust.

WAAAYYY too big. You're talking about 115g - more than twice the 48g of the 2210.

I think the 2210 is a good first choice, and if you read through the comments, you will find that others have put as much as 200w through it. I think you will find that with a 9x5 prop you can get close to 1000g of thrust with careful throttle mgmt. That kind of power, sustained,will burn up the motor real quick.

FYI, for most 3d applications like your Edge, you will want a 2 to 1 thrust ratio. This plane All Up Weight (AUW) will be around 500g; so if you can get 1000g out of this motor for very short runs (not more than 10 secs) you're right there.

Hope this helps.

Perfect. I saw your other post in my other thread and I forgot about this one and just now saw it. (those posts were done at the same time)

I will have this other one as a back up for another project.

I plan on making the extra as light as possible. (Lightweight servos and battery/Rx etc.)

With the 2210 a 25-30 amp ESC is better than a 20 am correct?

I have both laying around and it seems I would need the bigger of the two to power the 2210.

Should I get a bigger than 25-30 amp ESC for it ro with that be enough?

I am planning on using 100mah 3s 25c batts in it. (90g)

Would a smaller lighter battery, or larger 12mah be better or is that good?

Bluemeane,

Let's look at a couple things:
1. The 2210 motor will give you about 150 watts (according to the specs)
The all up weight (AUW) of the plane is 490g (17.4 oz) or about 1.1 pounds
This gives you 150watts divided by 1.1pounds = 136watts per pound (low 3d power).
A motor capable of delivering 180 - 200 watts or around 30 oz (840 g) of thrust would be excellent.

2. The 2210 specs say it will handle 15a so the larger esc is ok but I always go a little bigger to the 25a ESC is a better idea as it will easily handle the loads and should not get very hot.

3. You mentioned 100mah batteries....did you mean 1000 mah? Then you mentioned 12mah...that would be tiny...did you mean 1200 mah??

On a plane of this size I would a 1300 mah battery. You should balance ok and get good flying times. The 1000 mah batteries might be alittle smallish for this plane.

Hope this helps out a little. Looks like you are on the right track though.

Yes I meant 1000 and 1200 (I am posting these at work and have to type quickly sometimes in order to do so lol)

So the motor will work, just not the best?

It seems that some people can get +-800g of thrust from it fairly easy.

I posted this question in a different forum here and I also asked about this motor:
http://www.hobbyking.com/hobbyking/s...dProduct=23214

And someone said I must be joking because of the weight... But if the power of the motor makes up for the extra weight it shouldn't matter right?

Specs:
RPM/v: 730kv
Dimensions: 41 x 28mm
Shaft: 5.0mm
Voltage: 11.1v~14.8v
Weight: 115g
No-load current: 1.9A @ 11.1v
Max Current: 35A
Max Watts: 330W
Mounting Holes: 51mm

Prop Data:
12x6 - 11.1v - 16A - 1060g Thrust
13X4 - 11.1v - 15A - 1140g Thrust
10x5 - 14.8v - 16A - 1180g Thrust
