Change Sun 12 blade 120mm


Well after getting the 90mm version in hand I am really excited to get the 120mm 12 blade fan now. Im hoping they increase the price linearly ($0.50 per mm based on the 90mm) so it should be in the $60 range right?

Iíve got a NEU 1521/2.5Y ready to go for this fan and I intend to put it in a Falcon 120 on 12s.

If you get any more info on this one FF please let us know.

Cs claims they are out of testing phase on them Iirc, would love for this to be a low Rpm fan....there are plenty of 5055 & 5065 low kv motors in the 30$ range that can be used

The only problem I can see with those is the current draw would exceed what they can handle. With my 1521 I am expecting 5kW. I donít think a 5055 could handle 100 amps at 44 volts. I agree though, there are certainly some cheap motor options out there. I know itís not $30 but the HET 700-98 670 KV is an awesome motor for $160 and would probably work well with this fan.

Hopefully they are smart enough to make the motor tube large enough for all of the high power outrunners - maybe 50-55 mm?

if not, just do what Lee does and make your own standoff for an outrunner.

I know they are close, they have been testing the hell out of it to try and make sure it is good before they release them.
I hope soon, I would like to put one in my falcon 120 too!

A 1521 is going to be too small for any 120mm size fan. I have burned up enough of them to know! A 1527 with a Kv in the 700 range would be fine.

Even with a 630 Kv? I figured that would be low enough to keep me out of trouble. Im not one to push things too hard.......yet.

or you could send your motor in to Lee to get it rewound. he does some fantastic work. he's deffinitely found the most power on the cheapest budget. 16lbs of thrust for less than a hundred bucks is my kind of budget at this point in time. I'de love XPS, but it's out of my price range after this recession kicked me in the groinal region. LOL.

Lee had been putting 4 to 5000 watts through an HK 5060 sized motor for a while now.

A 500 kv 5065 would be nice for 15 pds of thrust at 4500 watts

OK, your talking about the heli motors right? I was thinking the .90-1.20 equivalent outrunners like the one I have on my Extra 330 and I know it can not handle anywhere close to 4.5kW without melting. Hmmmm...might have to add one of those motors to my next HK order.

Yeap, I'm talking about the SUPPO heli motors (low kv) and the red Turnigys...they can eat some watts in the 4-4500 range and that's what it seems like the sweet spot for fans these days.

Quite as it's kept, the SUPPO 910kv motor can length is 12mm longer than the Turnigy 880v but it's diameter is more narrow. At 37 a piece I got one, gonna try it with the 120mm CS blade fan when I get a thrust stand built.

If the housing remains the same as the old 120mm CS fan unit, then it will take scorpion 4035 motor perfectly. but just to mention that the holes for fixing the motor are probably made for M4 screws, might be a little too big for m3 screws which used on scorpion 4035.

Who carries the larger Suppo motors other than HK? Are the ones HK sells the big ones?

630Kv might be ok, but you can't run it for extended period of time. It's just a small motor. Too small for the job really.
