SunnySky X4112S 320kv

[eyeflying]

Just ordered a set of SunnySky 320Kv motors. I can';t find any reviews on them so I was wondering if anybody here knows anything about them or has any experience of SunnySky motors?

I';ve never had any of the SunnySky motors but, I have seen them about they look like they are good quality, that';s a very low kv rating what size props will you be using with them 

[icedfusion]

Well, I have bought shed loads of the sunnysky branded motors and they are very good motors IMO. I can';t compare them to the Tigers etc which usually cost 2x or 3x as much - but I suspect they will be on par with them at a significant cost saving.
I have bought:
2212 1400kv (at least 15 of these)
2212 980kv
and a few other versions which escape me at the moment.
The only problem i had was a box with one of the motors was missing a collet. Bit annoyed at this, but it was OK, as I had an almighty crash that ruined a motor but collet was good!

I was looking at those motors you have, but I wanted to put some large carbon props on it but I don';t know if it would be best to have the props bolted directly to the motor (i.e. as some of the rctimer motors allows).

I will be interested to know your thoughts on these motors. Out of interest, where did you buy them from?

5s and big ****** prop lol

I';m going to fit 15';s bolted directly on to the motor - I believe there';s  choice of prop mounts with this (see pic).

And whilst you';re on the subject of RCTimer - why do so many people buy stuff from them? - they seem really expensive to me. I';ve never bought anything from them as I always manage to find the same or similar elsewhere for much less. Although I may make my first purchase when they get the APM2.5 Clone back in stock!

I bought these SunnySky Motors from here: http://www.himodel.com

I';ve got a wholesale account with them so pay less than the prices the show on their site. I was going to get the Hengli motors but they were out of stock - these are a bit of an experiment for a serious ';Heavy Lift'; Hex on a hybrid frame - the bits have just arrived today - its like Christmas here! (no motors yet though  )

[icedfusion]

I agree about RCTimer being expensive for some things. However, for certain products they are reasonable and you know that you won';t get screwed.

i.e. carbon props are reasonable
apm2.5 is sooo cheap
some motors

For the sunnysky - I tend to buy them from hobbydream - they tend to be 25% less than on other sites I have seen - however, they only sell the models on the site and not some of the low KV ones.
I did a search for the motor you list on himodel but I can';t seem to find it?

They';re definitely there. Try this link

Great Morning! Christmas has come early (in the shape of DHL). Just had my delivery of the SunnySky 320Kv Motors and 15" CF Props.

Initial comments... the build quality of the motors looks excellent, very nicely finished and machined. Incredibly long cables - around 500mm - plenty to play with there. And yes, the props can bolt directly to the motor although they do come with a prop adapter as well. Nice sturdy 4mm shaft too and what looks to be serious heavy duty bearings.

Initial reactions? - very impressed but just need to build something to fit them in now

[Gaza07]

Couple of pics would be nice  did you get stung for duty ?

[eyeflying]

Will post some pics later.

Haven';t paid any duty yet. They came via DHL and they tend to send the bill in later. TNT and Fedex do the same. Its only Parcelforce that won';t release the goods till the Duty has been paid.

I';ve never paid ';Import Duty'; - just the VAT and admin charges. There';s no import duty on goods imported with a value of £135 or less and HMRC waive the Duty on goods with a value of more than £135 if the Duty Due is £9 or less. So, in effect, that';s goods to the value of around £160.

The trick is to get the seller to under declare the value of the goods on the shipping invoice to say, less than $230. Most decent Chinese companies do this as a matter of routine. However, what you DON';T want them to do is declare the goods as a ';Gift'; - this rings alarm bell at our Customs & Excise Office and they will then make an assessment of the value!

Probably teaching you guys to ';suck eggs'; here - sorry if I';m stating the obvious

Pics of my new arrivals. I fitted one of the props to show that they can be mounted directly. The box says that the bearings are Japanese but it looks like it says ';Thailand'; stamped on them

[Gaza07]

They look very good thanks for posting the pics, I like the way the props fit

Google bought me here :)

Keen to know how you got on.
Are they really 150g?

Not done anything with them yet - still in the box 

I can';t make up my mind on the frame. Don';t know whether to build a custom frame from scratch... Use an ';off-the-shelf'; carbon fibre frame... or make up a hybrid frame by mixing the two previous options. I';ve got a Q800 frame that would do the job and I';m thinking of changing the motor mounts to Sigma Mounts to cope with the larger diameter motor can and also house the bigger 45amp Esc';s which I intend using. My reservations concern the stiffness and strength of the booms - although they';re 16mm carbon fibre, I';m still not sure whether they';ll be strong enough for a motor with this amount of torque.

And yes, they DO weigh 150g each - I just checked them on my scales 

[icedfusion]

They look like some awesome motors! When/If i get my CNC machine I will make a frame and use those on it!

[mr_westie]

150g, Ouch.
I guess that does include 600mm of wire :)
So motor on it';s own might be about 120g?
Which is about right for that class of motor
70g, 100g, 120g.

I am getting some custom large plates made by these guys.
www.rccut.com
Roughly 260mm.
Qoute came in at us$40 each.

The largest commercial plates are about 230mm.
Even in the really big ones like the cinestar 8

What are you going to use for the booms?

[mr_westie]

16mm CF
If the 1mm wall is not stiff enough then will go with 1.5
http://www.flycarbon.com/


Staying with 16mm for now as I like these clamps.
http://www.shop.aglhobbiesllc.com/cart.php?m=product_detail&p=33
Lots of surface area vs the usual ali ones.
http://www.omgfly.com/index.php?main_page=product_info&cPath=1_41&products_id=649

A flyer I talked to did say he had issues with torque problems on the 16mm
He was using the narrower ali clamps.


If that is still not enough boom then go all out to 25mm

I bought a load of these for my next custom build:

http://www.kiowa.co.uk/products/c3_standard_polypropylene_pipe_clamp/FC3A16

16mm polypropylene clamps for 76p - this company supplies hydraulic hose fittings - and guess what, 16mm is one of their standard sizes. I got a big bag of them!

[mr_westie]

Good point on alternative sources for parts.
It does not have to have "Aircraft Grade" on it to be useful. :)
