THANKS ive never heard of alumide befor? i just started reading about it and it is aluminum mixed in with the the plastic im not sure how good it would work as an heatsink but for only 2$ more it's worth finding out

Quote:
Virtox on 2010-02-25 14:12 I'm no expert, but I had a look :
The datasheet for alumide shows 0.5W/(m*K)
While normal Aluminium is 237W/(m*K)

So I don't think it will make a very good heatsink.

Too bad, would have been cool >:-)
ok it will be a terrible heat sink sorry nitro so the heat conductividy of the alumide is correct (0.5W/(m*K)) here is the Data on diffrent matterals http://www.frostytech.com/articleview.cfm?articleID=233 so i would take it in silver then lol

From Shapeways:

Quote:
Alumide is White, Strong & Flexible with Aluminum dust mixed in. It is made using the Selective Laser Sintering process. The material has a higher heat resistance than regular plastics. Its melting temperature is above 172 Celsius It costs $1.99 per cubic centimeter (plus $1.50 start up costs per model).

The surface is smoother than White, Strong & Flexible (WSF) and is a matte grey with speckles of shiny aluminum dust thrown in.

Hi NC,

Have you tried the 9000kV outrunner sold by SydneyRCJets on your EDFs?

http://sydneyrcjets.com.au/motors-c-...-edf-jet-p-317

I was able to get about 70g thrust on a 2S, 35mm EDF. Would be awesome if this motor fits the 25mm EDF case!

This outrunner is too large to fit into the GWS 30mm EDF case. A 10.5mm motor housing would be perfect.

Rough info on the motor:
10g (including wire leads)
Mounting plate 10mm dia, screw hole-to-hole 8mm
Outrunner can 14mm
Total length 38mm
Shaft 1.5mm (threaded)

The 35mm EDF (5 blades) is gutted from a resale HK MIG 15.

http://www.hobbyking.com/hobbyking/s...dProduct=17309

Specs:
Wing Span: 390mm
Length: 390mm
Flying Weight: 95g
EDF: 35mm with 9000kv Brushless Outrunner Motor
ESC: 6A w/BEC
Servo: 3 x 2g

Can't advise on the amp count as i do not have a watt meter. However, the following are some stats from my last measurement:

Thrust: 80g
2S 500mAh 20C Zippy lipo
TGY 6A ESC (39C) after 30 seconds WOT

Based on similar SkyAngel 35mm EDF planes, this motor can take 3S on 3 blade. It will be interesting to see the results of a hot wind on this.

For anyone interested, I've just uploaded another request - a 25mm EDF Case with flange for 8.5mm motors.

NC,

I can fit the TGY 1015 into the 30mm GWS housing but not this outrunner. You would have to provide more tolerance for a 10mm can in the 25mm housing. How about a rotor with 1.5mm (shaft) to boot?

For those wanting to gear up ready for the Great Planes 10mm motor when it lists as a spare part, here is a 20mm EDF case (no flange) to suit: http://www.shapeways.com/model/45289...0mm_motor.html

.

You will get ~45g of static thrust on 3S using a GWS 30mm rotor chopped to 3 blades and clipped to 20mm.
