Hello everybody,

I have a hexa (2200-2300gr AUW) running dt750's on 4s with 1047 Gemfan cf reinforced props. The dt's are pretty old already and some of them sound like a coffee grinder...
I am sick of low quality motors, I also believe the dt's have a pretty bad efficiency.
So I am seriously considering an upgrade, I have come up with 3 options:

RcTiger MT2216: http://www.rctigermo...p?contentid=143
I haven't decided between the 900kv or the 800kv but 800 sounds more suitable to me.

Sunnysky 2216: http://www.foxtechfp...otor-p-383.html
These are multirotor special (short shaft, bolt on prop adapter).

Sunnysky 2216: http://epbuddy.com/i...products_id=270
These are for airplanes but the only downside I see is that the prop adapters rely on friction so they might slip...

I plan on using 1047 for the 800kv's and 9047 on the 900kv or 880kv.

So do you guys think that the Tiger motors are actually worth the nearly double price? (50*6=300, 26*6=156!)
And if not which one of the Sunnysky's are better?

Thanks in advance,
Exyator

you could simply change the bearings, it's a question of minutes, almost no tools neaded (plyer, small screwdriver), and should not cost you more than a few bucks.
I've rewinded my DT750s. They now have a kv of 900 and the thrust of 1600g on 3S with 11x4.7 gemfan (stock 1200g) !

Gravity, which Tigers are you using and what are the specs , prop size, weight of the motors, purpose for building etc.
I am planning on buying some good qualilty motors and esc's for my next build and am thinking of the AXIs' Anybody using AXI's here?

Thanks for the idea but I kind of want an upgrade :P , also this is an fpv hexa so not really looking for extreme power.

I'm using Tiger motors.

Seriously considering them but before I drop 350$ I would like an opinion on the Sunnysky's, I know SeismiCWave uses them so they must be not bad.

My hexa doesn't have room for more than 10" max 11" props, also I really don't need that much power (I'm only carrying a GoPro and FPV equipment).

Thanks for the reply's!

Anybody using the Sunnysky's?

Cheers,

Himodel also has SunnySky 2212's (980kv) and 2216's (800kv)

I plan on using the 2216's for my Discovery build. Should provide a bit more pop than my RCtimer 2830 750 motors.

Tigers and the Sunnysky as far as I know are the same quality of motor and likely made by the same company. I love my 2216-900 Tigers. Have them on both my QAV500 and my soon to be built Discovery.

So my brother just bought the 980s from foxtech and got them the other day. They seem well built, and are very similar in design to the tiger motors. I just purchased the 800s from himodel and I'll report back on how I like them. I'll be putting them on my Discovery.

I have these on my big hex, and I've only flown it a few times, but they seem well made and all of them spin true. They're an incredible value for what they cost. I think you'll be happy with them.

Nice! Thanks for that. Makes my investment seem less risky now.
