Crap, now I can't find it either... >< I'll keep looking for it. It was basically an intro to the Edge when it came out last year that I believe Skip?? started. He posted a few things like weights, dimensions, flight report and a few other little details. I think I posted all my unpacking of the Edge pics in it as well just like the OP did on this thread. I too couldn't believe how well it was packaged. It took me 3 hours to unbox the plane and engine.
Anyway, I'll keep looking for it. It was posted under a different titled thread I remember.
Also wondering if you guys had any of the issues with your Edge as I did. My biggest gripes were:
1. The LG slots in the fuse (where the aluminum supports are against) were much too narrow to try and slide the gear in easily on both sides. I'm not sure if it's because it's just so dry here that the wood shrunk that much, but it wasn't even close. I had to go buy a file set and file out each LG slot for a good 10 minutes each. It fits perfectly and VERY snugly in there now and the bolts line up perfectly, but there was not a chance the gear would go in without major filing. Not a biggie, but a bit of a hassle.
2. The wings & stabs all seemed to have slightly offset wing pins? where they insert into the fuse to keep the wings/stabs from turning and to maintain/adjust your incidences. They all were about 1mm too far forward facing. I had to lightly drill these out a bit further as they wouldn't fit in very well out of the box. I think I only took off a 1mm on the front of each slot to make em fit. Didn't affect incidences at all, and was nothing more than a bit of an annoyance.
3. No holes in the cannister tunnel to mount the fuel tank. Not a biggie either as it allows you place it where you want though. I drilled my own holes for the zip-ties and mounted the tank as far back as I could to keep it on the CG point. A dremel would also work well here, but I needed large holes to fit zip-tie clevesis through.
4. The only other issue I've found and it's probably only because I'm using a huge Fromeco Wolverine dual failsafe switch, but I'll likely have to glue in a piece of balsa to actually allow me to mount this beast. :) This airframe is so light that it's hard to find room to mount to! haha I was impressed that it already had 4 predrilled switch mounting locations though. Downside is it's for standard switch sizes.
Other than that my build went perfectly, but yes quite long. I have been very impressed with the quality throughout. I also used MPI aluminum arms, not the included ones but did use all the clevis ball-link hardware that came with it. It's the same quality/stiffness as the dubro stuff as I have both on hand to compare and use. I'm using the stock tank (but with my own tygon lines, clunk, etc). My covering was actually 100% tight when it arrived at my door. Absolutely 0 wrinkles at all. Was the best covering job I've ever seen actually. After sitting in my basement in DRY DRY Alberta for a month, it did start to wrinkle a bit as the wood shrunk, so I went over it with the gun. Still tight. BTW it is TRUE Ultracote from what I can tell. I bought some matching covering for another plane and it's an exact match (both red and pearl yellow).
As for the canopy, nice job on rounding it out. I glued mine on rather than screwing it on but was simply preference.
I'd also do some epoxying around the top of the LG inside the fuse as that's where a lot of the force will be on hard landings as the alumninum protects the bottom half. Probably not necessary, but I'd rather be safe than sorry. :)
Anyway you must be excited to fly yours! I still can't wait and am getting sick of just looking at it in the basement and not flying it yet, lol. I've also decided I'm probably going to open up the cannister tunnel covering so I don't have to vent and hack up the cowl much. That should keep the engine very happy.
Good call on clear-coating the pants. I didn't even think of that at all as mine too are flat yellow. I kinda liked them as is though.
On my weight, keep in mind that I'm using a LIGHT setup. I tried to save as much as I could. I custom built all my extensions so I didn't have a mess of wires (ie. my 6" extensions are 5" on the ailerons for example.) I'm running 2x 2300 a123's I custom built (originally was 2x 1100mah but I figured it wasn't enough for very many flights and I'd always worry about it), 1x Zeus and 1x Wolverine. That allows me to get rid of IGN battery, switch, ect. and I have FULL battery redundancy, dual failsafe, 2x inputs to RX for power, a built in Opti-kill, IGN light, switch, etc. So my component weight is nearly half of what most people run with NI-MH or Ni-Cd.
BTW here's some helpful info I calculated the other night. I calculated exactly the MAC and CG points. 27% MAC is 117-118mm (as per manual which was suprisingly right-on), 30% is 131mm. I'm just going to CG mine within the two to start with and go from there.
Hope this helps!
