I'v had this for over a year and have just completed it, not without making a few mistakes of course! :o
I really like the look and sturdiness of the airframe and the fiberglass cowl. I used an AXI motor mount from www.smoothair.ca.
I should have weighed it first, but as I have another one, I could always weigh that.
Once again I am using SP400 stuff I had previously. A Mega 16/15/7, Castle 25 and 8 2/3 GP1100 and some 8 cell Kan 950's (last season for these).
I may go to Lipo for all my SP400 this year as prices continue to drop and the quality has increased across the board.
I also bought a Berg 4l for the receiver.
All up weight is 22 oz. which is about 1.5-2oz. heavier than others who have smaller motors and 4 oz. lipos.

OK,
This was purchased about 2 years ago and I finally completed it about a month ago. It's a 7-8 cell (round cell) pattern plane with a fiberglass fuselage and a balsa sheeted foam wing. It has about 270 sq. inches of wing area and weighs 49 oz. That's about a 26 oz. per square foot wing loading :eek: With 8 IB 3600 NiMh cells, I get about 400 watts fading to 370. So it's about 120 watts per pound. Motor is a Mega 22/20/3e spinning a Graupner CAM 11x6 folder. Definitely not a floater. I haven't flown it yet as I'm conflicted about using the NIMH cells or taking the plunge into Lipos. I made the mistake of telling the wife about Lipo fires and she hasn't forgot :( . The good news is that A123 cells (Dewalt 36V packs) offer a significant weight reduction and are safe. Either Lipos or LiFE will give an 8 oz weight loss.
I have to say, this is the second F/G fuse from the Czech replublic that I have had to fix. They put plywood disc in the fuse while it's being molded and the disc is never parallel to the nose. I had to grind it out and put in a new fire wall. THe other thing that really annoyed me about the plane is that the chord of the wing was longer than the canopy opening for it. I had to grind out the canopy opening and now it looks like :censored:
I decided to leave it as it is as this is one plane that you could spend hours on trying to get it look perfect and right now it's good enough to fly.
I decided to have a split "Y" elevator linkage and it was a pain but it will work better than the "U" shaped wire that came with it. Kudos to Foss1997 for the idea he used in his Rumfal. He made the mistake of relying just on the glue. I used a mechanical connection as well The red scallops on the vertical stablizer could be done better and I will re-do it once it has flown a few times. The Testors dark blue paint isn't a cloase match to the insignia blue covering I used, so painting will be done later.

On board video
I even have on board video of one of the flights of it as well. I had the camera mounted on it's side and had to rotate the image. I'll do much better next time:

I just received an E-FLite six series 2000kv motor and F-27C mount. I'll be putting that on in the coming days. As cold as it's been, I doubt it will see any air time soon.

Well, I've been on RC groups for quite some time but have not posted pics or a build thread, so I think I'll start trying to become a little more active and share with others what I've been doing. Last year I decided to get another flying wing to replace the FMA razor I foolishly sold. The flying wings greatest attraction to me is that you can't really hurt them, which makes it a perfect plane to warm up on or try new things with.
The downside is that without a ruder, aerobatics are more limited. However, I'm going to upgrade it to brushless and maybe start using lipos with it in the spring. I may just keep the NIMH in it and pump up the watts a little more.
I painted it with Testors enamel paints trying to make it look reminisent of the Thunderbirds scheme. It was also a test of the paint and the colors for another airplane. The Testors did not attack the foam at all. Even though I really didn't bother to do a "perfect" job on it, the more i look at it, the more the chrome paint on it impresses me. So much so that the next one will probably chrome paint also. Here is a picture in good sunlight:
