jonryan Posted January 12, 2017 Share Posted January 12, 2017 Anyone tried one of these? I'm after a motor for a Sharkface (target weight about 10oz), and this looks the biz. But 6g? Doesn't seem it could be very robust at that weight. And what's that connector? Quote Link to comment Share on other sites More sharing options...
Denis Watkins Posted January 12, 2017 Share Posted January 12, 2017 That connector is a regular PCB header Jon, from electronic shops or eBay Quote Link to comment Share on other sites More sharing options...

jonryan Posted January 12, 2017 Author Share Posted January 12, 2017 Ah! Thanks Denis. Will it take a 10A/10.8v set-up do you know? Quote Link to comment Share on other sites More sharing options...
PatMc Posted January 12, 2017 Share Posted January 12, 2017 That motor is too small to give the required power & it's overpriced - should cost about half as much. You going to need about the same weight as an 049 glow or .8cc diesel so may as well get a motor of around 50 - 60g. Never had a Sharkface but I'm using an AXI 2208/34 in an X-Kraft. The AXI is really too pricey for such a model but I got it S/H. Something a similar weight, KV & max amp rating should be good in a Sharky. It's 57g, 1100KV & around 10A rated - I use 3s 900 lipo.

jonryan Posted January 12, 2017 Author Share Posted January 12, 2017 I was planning to get a 17g 1600kv on three cells. That should work out at around 14oz of thrust with a 6x4 prop. Axi aren't half pricey! I'm yet to be convinced that the extra cost is worth it on chuckabout models. Quote Link to comment Share on other sites More sharing options...
Phil Green Posted January 12, 2017 Share Posted January 12, 2017 A 6 gramme 14mm motor is too small for a Sharkface. Our group flies a lot of Sharkies and we generally use these on a 2S 800: Emax GT2205 Cheers Phil Quote Link to comment Share on other sites More sharing options...
MattyB Posted January 12, 2017 Share Posted January 12, 2017 Completely agree with PatMc; that motor is way too small for your purposes. Remember the 3W/g rule for cheap motors - multiply the mass by three to get a rough real world max power in Watts that the motor can generate without overheating. From that you can calculate a max current at the voltage you are intending to operate it on. Edited By MattyB on 12/01/2017 11:32:38 Quote Link to comment Share on other sites More sharing options...
John Emms 1 Posted January 12, 2017 Share Posted January 12, 2017 How does this look for the Sharkface? **LINK** The dimensions are for the outside of the case. 5x5 on 3S would keep the pitch speed up. Regards, John Sorry, the complete thread had not loaded when I posted. Please go with what is proven.

jonryan Posted January 12, 2017 Author Share Posted January 12, 2017 Phil: Thanks. That's about what I thought. Is my weight target about right (~10oz)? I'm putting an elevator on mine. And 6x4 prop? John: That looks OK. Does it have connectors? Quote Link to comment Share on other sites More sharing options...
John Emms 1 Posted January 12, 2017 Share Posted January 12, 2017 Posted by jonryan on 12/01/2017 11:43:01: John: That looks OK. Does it have connectors? Hi, the two smaller motors in that range don't have connectors, simply bare ends. I was looking again at the specs for the smaller C1826/31, but you need the power equivalent of a can 400 6V - which beats a Cox Black Widow by 1000rpm on a 6x4. I like the look of the 2028/20 far better for the Shark Face. Regards, John Quote Link to comment Share on other sites More sharing options...

I Yep the one in the pic is about 10oz, quite a bit lighter than Eric's original Posted by jonryan on 12/01/2017 11:43:01: I'm putting an elevator on mine. What on earth for? its a single channel model, probably the most popular single-channel model ever! Cheers Phil Quote Link to comment Share on other sites More sharing options...
jonryan Posted January 12, 2017 Author Share Posted January 12, 2017 "What on earth for? its a single channel model, probably the most popular single-channel model ever!" I'm still a rookie. This will be my first small, fast model; I'm going to need all the help I can get! It isn't going to fly quite the same as the Astro Hog I'm working up to my 'A' on.

Phil Green Posted January 12, 2017 Share Posted January 12, 2017 Loops, rolls, immelmans, and land at your feet without an elevator and with sequential rudder only: Here's one of Rons many Sharkfaces.

jonryan Posted January 12, 2017 Author Share Posted January 12, 2017 At the moment, I can take off and land, sometimes on purpose. Single channel Immelmans will have to wait for now! Quote Link to comment Share on other sites More sharing options...
Denis Watkins Posted January 12, 2017 Share Posted January 12, 2017 Jonryan, thee examples shown illustrate what can be achieved, but the easiest model to fly, and to get out of trouble, in my view, is 4 channel. Now, a rudder only, almost free flight model can be guided around, an is a pleasure, especially if you built it yoursef, but if a gust puts it inverted, you would be glad of ailerons. There are 100s of suitable models out there. HK has a 4 channel Mini Stick, ready built, with the motor and connections that you queried in your original post for £20, and it just needs micro servos, lipo and RX to fly, have a look.

jonryan Posted January 12, 2017 Author Share Posted January 12, 2017 That's why I'm mostly using an Astro Hog for learning. I've got a lightweight 3 channel for calm days in the field next to my house, and a four channel trainer I built from a Traplet plan but which can be a bit of a handful. The Astro was built by a very experienced flyer, and is a delight. Quote Link to comment Share on other sites More sharing options...
