GWS Me-262 Build thread with the GWBLM005A Motor

I have just recieved my Early bird Kit and here are some photos of the way the components are packed in the kit box.

All the small platic bits and things like wheels and undercarriage wires were separated from the foam pieces by a layer of coregated cardboard so there was no repatision of the indents in the foam that mared my GWS-38. Each foam component was inividually placed in its own plastic bag. As Bthree said the nacellel ar huge.

After I finish this post I am going to set up one of the EDF64s with a GWBLM005A 3900kV Motor on my test stand to take some readings.

I have Test run the EDF-64 with the GWBLM005A 3900kV Motor and got the folowing results using the GWS wiring harness supplied with the Me-262. The battery used was a 3 cell 1800 mAh pack.

One EDF-64 with a GWBLM005A 3900kV Motor
10.25 Volts
10.8 Amps
111 Watts
27510 RPM
Thrust 322 grams (11.5 oz)

These figures roughly agree with the GWS Web Site.

This means 23 oz thrust for a 25 oz aeroplane. 27510 RPM gives an eflux velosity of about 100 MPH so the aeroplane should have good turn of speed.

P.S. Yes! The fan is Black and the shroud is too.

I have completed weighing the foam components in the Kit and they came to 296 Grams. After adding together the weights of all the pieces that will go into the aeroplane I get an estimated flying weight of 717 grams, equal to 25.6 oz, without an undercarriage fitted.

The photo from Ken with the ducted fan and BL Inrunner is different from mass product.

I was told -- speical service for early birds was done.

Mass production -- without the ext. wire soldered to the inrunner.

info to help you install GWS-262

Early Birds,

I am still trying to get the manual for you. Still do not have the info.

But the nose cowling is different from requalar GWS kits.

Please see the photo.

1. You open the nose cowling to put battery.

2. To open it, you rotate the nose.

3. There is a spring at the bottom to lock the nose.

I do not have the kits with me to check or see it. Please correct me if I am wrong. I think with the only info here will get your a rough picture of how it works.

will update you.... Welcome to add comment if you have the kit(S)

Secondly two photos giving the measurments of the battery comparment.

Tomorrow I will build the wing and nacelles including the motor mounting.

I opted not to EB the 262, but will pick one up as soon as it hits my LHS next month. Looking forward to reading your progress Ken.

Does the kit include the fan you are using? Is it new version 2 fan?

I have joined the wing using 30 minute epoxy. The use of 30 minute epoxy allows some set up time to get the two halves in alignment.

I placed two 1 inch thick balsa blocks under the nacelle mounting points and a piece of 1/4 inch balsa under the center of the wing. the two surfaces of the wing join were then painted with 30 minute epoxy. The bottom surface of the wing join was taped togeter tightly and this stops epoxy from running out the bottom of the join.

Next the wing was carefully aligned by moving the two one inch blocks to get the right dihedral. Then I used my robart Incidence meter to ensure that both wing pannels had the same angle of incidence. When I did this by eye there could be a variation of around 1/4 of a degree in difference.

I am now waiting for the epoxy to harden properly. About 2 hous should do it.

My kit came with two EDF-64s assembled and with the leads shown already soldered on. They are the Version II black fans. The EDF tested in post No 2 was the suplied EDF-64/GWBLM005A assembly.

Ken

So you got the brushless fans that came with the kit and they are already assembled? Are the fans balanced? Any rubbing?

Getting an assembled fan that is balanced and not rubbing is a very good deal.

I recieved an email today from Joyce that my GWS ME-262 has been dispatched. In preparation, I already purchased the fans and the M005A motors, because the version offered in the early bird email was NPS. Are you saying it comes with fans and motors anyway?

Thanks, John
