Default Airliner EDF Project (Suggestions for a Twin EDF Power Package)

Hello guys!!! I am searching around looking for power suggestions for a new project EDF Airliner.... The airplane is the Mr. Ming Windrider. A 380 style looking Foamy designed as a Slope Glider.... I will make it look like a Boeing-777 with only 2 X EDF's so they can be a little on the big size as is the real one. I can alway duplicate the size with the engine cowls. I will also add a retract landing gear system and a lighting system. More weight will be added by a light covering system and paint. Some specs on the plane from Mr. Ming:

Ming’s Windrider

Wingspan: 1.8 meter
Wing Area: 4.65 sq'ft
Weight: 2 lbs 5 oz(glider)
2 lbs 12 oz(EDF) I think my plane will be closer to 5-6lbs.
Wing Loading: 7.95 oz/sq'ft(glider)
9.46 oz/sq'ft(EDF)

A couple of guys have suggested going with:
2X MINI-480 FansUnits
2X Typhoon Motors: 2W-20
2X 60 AMP ESC's
2x 3000mAh or bigger 4S 20C Lipos

Another option:
2X Mini Fan 480's
2X Typhoon 3W
2X 45A ESC's
1X 3300mAh or bigger 20C 4S Lipo... Better 2X 2000-2500 4S packs.

OK, I am open for all suggestions, I would like to get this sorted out so I can get going on the build....I really don't want to do too much experimenting with the Power Side....I appreciate your valued experience...
Standing-By,
MOJO

Hello Grumman,
I also have one of these planes waiting for an EDF conversion. On one of the forums, I've seen one fly on a pair of GWS edf-55's with 20mm 4100KV brushless motors. It had to be hand launched and the flight was OK. I'd look into the FX EDF from hobby lobby. I've got a few and they perform as advertised. For an extra $5, get the nacell/mounting kit. Two would fly it, 4 would be awesome.

Hey Grumman, sounds like a cool project.

I took the easy way out and got the Eflite Super Airliner. Its Span is only 1.5 meters though so a bit smaller than what you are doing. (by about a foot) I used the suggested setup since I won it with the sugessted 400df eflite motors. It flies superbly with that setup with 2x 20 amp esc's and 2x 1650 Meh 3s lipos. It has more than enough power but at only 3lb 8 ounces it may not have enough for your projected weight.

Here is a vid I made of it with the camera attached which added anour 2 ounces to it.

Nice looking F-22 by the way!

Grumman,
You're on the right tract with the MiniFan and 2w-20 set up.
If your at 6 pounds all up weight I'd go with a Mega 16/20/2 on 4S :p
This is one of the best setups around for the MiniFan; 38 amps on 4s and about 600 watts!

By using 2 of these you will have a 1200 watt power system that only uses 38 amps (per motor) = smaller battery and smaller ESC

200 watts per pound and this baby will scoot

Send me a PM or give me a call during Biz hours at 815-228-7091

Have some other set ups that would give even more power but I don't think ya need it.

Thanks Grumman. I have so much fun with this plane. Everytime I fly everyone stops what they are doing to watch!

The camera setup is very simple. It is a 5in1 eDVR that I attached upside down in the rear air vent hole. I used velcro and some tape as a safety measure just in case but the velcro held fine. The camera only weighs 3/4 of an ounce so it did not take much to hold it in place. I have used it on several planes in different locations for unique shots. I picked mine up used from a user here on wattflyer for 50 bucks. One of my better investments!

Has something changed in electric sport planes ? 200 watts per / lb. ?

Is this airliner plane required to go vertical, or is the power system the worst on the market ?

I thought 60 to 80 watts on Brushes and Nimh does a great sport job.

Here is a page I found with some info from the manufacturer, can't seem to find a Distributor.

http://www.foreign-trade.com/showcas...ngowang&p=7499

Like I mentioned I got mine used from a guy here on WF. From time to time they will pop up for sale. You can find them on ebay from time to time as well.

I've wanted one of those Ming airliners. They look nice.
I opted to scratch build a smaller airliner a few months ago, when I was on an airliner kick. Its in may avatar. I guess the Ming would not be able to fly on stock brushed EDF50 fans, like mine does.

Maybe you could go low dollar with the GWS EDF64 and the bl motors they are using in their ME262?

Cyclops, the confusing thing is that the watt/pound figures do not take wing loading into account. I haven't seen decent tables that show W/lb, as a function of wing loading.

The little airliner in my avatar flies well on brushed EDF50 fans. Its probably at around 60W/lb. Wing loading is in the low 8's, if I remember correctly. Its tough to build that light.

Been using those NiMh's I sent you?

Randy is that 200 per motor? On my airliner I was getting about 125 per on my old batts (12c) but I just got some new 20c's and I am getting 200+ per motor now!

I haven't had a chance to fly it yet due to the dang weather around here. . It felw ok on the old ones so I can only imagine the power I am going to have now!
