After all of the "what decals should we give you?" All they put in the kit is that. What a waste of time.

I felt the same way too

That's one of the many reasons for the budget price.

Yup, theres no pilot, no drop tanks and no bombs. Looks like i might have to look for the depron option. But BartDude and Me are glassing the bird, i still wonder how much it will effect the performance

What we had shipped the EDF75 BL2815 within the GWS A4 kit is the same motor that GWS RD had tested and flown in the past months.

Every time take off from the ground, not by hand lunch!

There will be no reason what we can fly will unable to be flown by you!?

Well I got my A4 yesterday. This will be my first EDF. I think the kit is very nice, Getting the entire thing for $100 shipped is huge. The fit and finish looks very good, and the kit itself looks easy to assemble. I cannot wait to fly this bird! I do have problems with my fan assembly also though. Without even running it up I can tell that my fan will rub on the housing. I'm not even going to attempt to run it up without getting a prop balancer first, it looks like there have been a few issues with that so far. Overall though I think this kit is pretty darn good. I like the size of the A4, though I realize it's probably going to be pretty heavy. I guess I'm not as worried as most are about overall speed of it. Being my first EDF, I think something a little slower and more stable will benefit me in the long run. Good job to GWS for making a great bird for an honest price.

What are some other fan options for us if I wind up having some of the same problems with rubbing? I looked and found a couple 69mm fans. But measuring the fan DIA with my calipers last night it measured over the claimed 70mm

The fan is supposed to be 75mm, not 70. Check out the sticky thread here in the GWS forum and also the A-4 thread in the Foamy EDF forum. Those are the two active threads on this plane and have lots of info so far.

With GWS EDF75 plus BL2815 that you can take off from ground!

However, you need a good Li-Po which able to give enough current.

A 2200mAh 3 cells 20~25C will be a good match.

I like to tell you how GWS EDF75 recently had tested with proto type brushless outrunner motor to get such result:

EDF75 4 blades: 1728g at 5 cells 81A ( 1498W ) 3260KV
EDF75 4 blades: 1180g at 4 cells 50.2A ( 743W ) KV=?

Any one here may be even already got better test datas?

Hope this increasing of speed and thrust will bring GWS EDF75 powered models up grade their performance a lot!

However, need to be careful not to bent the wings!

Some of the old test datas that measured by using GWS BL22xx out runner BL motors during 2007 summer for your reference. However, I feel that were not good enough at that time.
