If you wanted to you can route the wires out of site. Just pull the fan wires and plug through to the inside of shroud, then hold the wires down the side of the motor (inside of a row of fins at least three fins from edge of shroud) as you snap the fan shroud on the motor. Doing this leaves a small hole/air leak where the wire use to exit, I just hot glued mine closed.

I would hate to see you buy a new Corvette, BMW or Porsche. They all come with plastic intake manifolds, but it does the job for keeping the air going in cool as it doesn't get hot.

@ suicideneil,

it's made in china so 13$ for alloy is possible or plausible

if it was alloy those grooves will make it look nicer and a little cooler

research for a 14$ thing sorry I'm to busy for that

@brushlessboy16

i know... the not funny part it's a bad render that didn't sow you what you will get.

BrianG,

I first brought it for the 'bling bling' the extra cooling it will give is just nice, i don't now if i need the extra cooling because i haven't run the MMM yet.

lutach,

uhmm okay?...

i have a alfa romeo, have driven a ford mustang v6 and it's crap in the corners, p.s. do you have corners? :mdr:

For $13 plastic is fine, as long as it doesn't fall apart. I would like to see the grooves as a part of the mold rather than a sticker though, that's just cheap.

A Mustang corners just fine for a 2 ton vehicle, if you know how to drive :na: FYI, that has nothing at all to do with this thread.

If you want a fancy fan in a big motor, get a Plettenberg or Lehner.

Let me explain it better. By using plastic, it makes it easier to manufacture and the fan does the job of moving the heat away from one source instead of 2.

What Alfa do you have? I had a 155 back in Florida, but sold it (Made a nice profit on it) to get a BMW. I like the new Corvette and I'm thinking of getting one or maybe a Ultima GTR, but the roads here in New Jersey are not too friendly. BTW I'm not American and I used to race go-karts in Brasil and yes we have plenty of corners in Brasil. Where are you from?

Yes plastic works as good but if you expected alloy it's a bummer if you get plastic with stickers on it :lol: (yes now i can laugh a little about it:whistle:)

I have a alfa 147 with a normal engine not a GTA it's just fine for now. I'm not full scale racing, some events we have here in the netherlands are pretty nice do (bavaria city racing rotterdam)

The thing is, it was said here that it was plastic: http://www.rc-monster.com/forum/show...8&postcount=41. It should do the job for moving heat away from the motor.

I like the Alfas and wish they would still be here in the US. I got to visit the Netherlands, I had a couple of girlfriends from there and they are beautiful. Tall blonde, one had green eyes the other had blue.

Having experience on the subject I can guarantee you that shroud could not have been machined aluminum and cost $13.00. It would likely be 30+ depending on the material used and there would have to be different versions for each motor diameter further increasing costs.

It don't have to be machined aluminum or CNC machined

I don't know the exact name of it 'form poured aluminum' that's very cheap to make a 3d shape like aluminium from GPM and Integy.

Like this one it's 10€ about 13$

Or this one

Ezrun 1/8 Heat Sink it's $4,80:lol:

You probably mean "cast"?

With Castle's finned motors, having an aluminum "clamp" would just be a waste. For aluminum to absorb the motor heat, it would have to make good contact with the motor. Castle's fan is just that; a fan, but in a cool looking "blower" case.

This is different than the "cast" parts, but similar in the fact that you need to make the mold before you can make the part. The parts are quite inexpensive to make AFTER you make the casting. Those extruded aluminum heatsinks are cheap enough AFTER you buy the extrusion head(couple thousand $$), but they are useful only for the motor size/diameter they are intended for. The Castle blower is universal in its fitment - "Fits on motors with outside diameters between 1 1/2" and 1 7/8". This universal utility would not be possible with aluminum(and pretty much "rules it out" for this particular item). I don't think any description of the item eludes to aluminum construction in any way - not sure how anyone would be "expecting" it based on the product description. :)

that castle fan is not a blower, its a YiMeng 7-bladed axial dc fan rated 3.4 CFM deduct some, for that slick shroud with a sticker on top obstructing the airflow

It could be replaced with a sunon maglev 4.9CFM, 30x6mm fan (cheaper than the whole fan shroud with fan): http://www.sunon.com.tw/products/pdf/DCFAN/GM3006.pdf
its half as noisy and more efficient
12 bucks here: http://www.futureelectronics.com/en/...GNSUNON3579810

i use this on mamba max 3-5S with 35V power cap

Sunon KDE1235PFB2-8, 35x10mm 5-13.8V, 0.8W, 6000RPM, 5.2CFM, 0.06A, 19.5dBA, 5 blades and this for 1900kv motor

Top Motor, DF127015PH 70mm x 15mm, 38,9CFM, 4,1W, 3-Pin CPU fan, 4300RPM, 0,34A1 12V, 37,5dBA, 11 blades

both 12v rated fans

"Designed in Kansas - made in China" Bah, sounds so Hollywood. Hobbywing at least use 50mm fans. A 30x6mm fan on a 2-3000+ watts motor is ridiculous. Overall efficiency is better with fans, good ones and big ones.

Pull a fan from your notebook or PC and see what happens to 'overall efficiency' :wink:
