Thanks for the reply Frank. Sorry to hear you crashed the edge. If you don't mind.. what happened??

For all you guys building your edge now, here are some recommendations.

1. Use nylon Dubro hinges especially on the rudder. The lower rudder CA hinges have broken twice and I finally replaced it with a Robart round hinge. Nylon hinges are better for high strass control linkages!!!
2. I am also replacing all the push rods. Two of mine have head thread slippage under the clevis. The lock nuts stripped the threads and the clevis slips. I am replacing them with Dubro ball joints and safety lock quick link and 4/40 push rods. I'm never using metal clevises again. The threaded base seems to open and slip on the threads from the vibration or when the locking nuts are strongly secured.
3. The aileron servos are mounted so the control horn is in the center of the hardwood block in the aileron. I think this is toward the root.
4. I now have flown my Edge 120 times. I use 12.5% nitro, a Saito 125 with the stock 10 oz tank and get 14 minutes of great Pattern and 3D flying. After trying several prop sizes I prefer the 16x6 APC. It does both types of flying better than with a 16X4 or 16x4W. It hovers well also.
5. I also removed the wheelpants. It now balances with no added weight, except on the left wing tip, and knife-edges with rudder only. It doesn't look as pretty but it flyes a lot better!!

I hope these suggestions help!!!

Hey Jeff. I was hovering well the best that I can anyway. Before I knew it it was over my head,I mean right over it I was almost doin a backbend.. I tried to save it then I saw I was over the pits and put it in so not to get anyone hurt. just before it hit i pulled back power and up elevator and it caught it bottom of cowl and landing gear. Flattened the gear right out,took the firewall out,and pulled the wingbolt through the fuse.. I will say it is one tough bird. It didnt even pull the gearblock out!! I would buy another Seagull Model no doubt. The new Yak is looking pretty nice.. Although I just got one of the ExtremeFlight Yak 74".

Just finished my seagull 540 edge and i will be running a saito 100. Wondering how much weight have you guys been adding. It seems that mine needs about 8or 9 oz up front to balance at 100mm.from leading edge of the wing. I place my servos in the tail as per the manual and the 4.8 volt battery up front as per the instructions. It seems like allot of weight but just wondering what you guys have found. Thanks in advanced for the replies. Lou

With a Saito 125, I ended up adding 2.0 oz. to the firewall, and my current balanced CG is slightly forward of 100mm.

When I built mine with a saito 100 I added 0 weight. Just placement of the battery and it balanced as per manual

I had a YS 120sf and my 6v 1650mah nimh was next to the tank.. Balanced nice there.

If anybody needs parts for their Edge. I have some after the crash..
Canopy Hatch
Both wings One need slight work.
Elev.rudder and stabs..
Cya,

Frank, you have PM!

I'm not a 3D flyer, just a sport flyer that dabbles in some pattern stuff. So, that being said, what do you think of this plane and a Super Tigre G90? I'm looking to replace my Hobbico Sukhoi.

mtwister

Having owned that motor, and having this edge, I will tell you that with that motor, it will be very scale like in flight, so power will be marginal at best.

jbloom

Hmm... well.. perhaps I should start engine shopping. I've looked at the OS Max 1.20AX and the Saito 150. I don't have anything in that range.

Tesla1856

I'm running a Saito 1.25 4-stoke in mine, but if this spec. from Tower is correct, it should work:

SuperTigre G-90 Ringed w/Muffler
Output: 2.5 bhp at 14,800 rpm

This is what the Seagull manual says on recommended engine size for the Edge 540
.61- .91 cu.in - 2-stroke.
.91-1.00 cu.in - 4-stroke.

With 15%+ fuel and the right prop., it should fly fine for sport and pattern.

mtwister

Good luck getting a ST G90 anywhere close to 14K rpms, unless you want to run an 11x6 prop.

The only prolbem i have had with this bird is the wing tube bends. i have had some carbon fiber tubes made for my edge. I have 4 tubes on the way. This should fix the wing tube problem.

I have a Saito 125 in my Edge and it balanced perfectly fore and aft and needed some lead on the left wing to offset the side-motor-mount.

It flys pattern maneuvers very well. Axial rolls and hands off inverted flight. Four and eight point rolls without rudder input. I use a 16x6 APC prop and it handles the faster speed for pattern flight as well as the slower speeds for extreme 3D and hovering.

It is not a a top level competition aircraft in either area but if you enjoy flying both with a single plane the Edge 540 is the ticket

rwbennett

I've been flying mine for a little over a year now and generally like the plane. I've got mine powered with a Zenoah G20 and the plane rocks. It'll pull verticle from an idle, nail it and it goes out of sight. Perfect power. The only downsides I have with the setup is my wing loading is bit on the high side and it tends to want to snap out with too much elevator or to low an airspeed. But landing speed is no faster than a traditional sport plane.

I've also balanced per the manual and tried different CGs but to no avial I can't seem to eliminate the coupling going on with rudder, when in knife edge i get a nasty oppsite roll and down pitch..so knife edge flight is a bit crossed sticks.

Overall though the plan is a keeper..and if powered with a 90-120 size 4 stroke to keep the weight down it would be even better.

I replaced my wingtube with a CF tube (I bent 3 stock tubes) and had rock solid performance since. I do need to replace the pushrods still. I do not liek them one bit. I will do as Tom suggested. I replaced my tail wheel and bracket with a sullivan since the old one broke after straightening it too many times. It has been great since. Never a problem with it. In order to balance it I used a sub c 5 cell battery and mounted it just behind the fuel tank. Since I am using the YS110 I also used a hayes 16oz tank. Have to say I love this bird. It is one of my favorites. Sure wish we had a good 3D pilot at our field who could fly this plane and tell me how to adjust it. It does not knifeedge without elevator input and aileron as well. I can do them rather well but it takes some work.

No offense to any piolot. But I always felt the pilot should "fly" the plane. Not the transmitter. That is why my opinion is that no matter what it takes to do a knife edge or any other thing for that matter means the pilot should be doing all the needed inputs. Not some fancy smancy computer. After all, if the computer is doing it, you aren't really responsable for what it is doing. And if that is the case how can you take the credit for it? Letting the computer do it for you isn't "Flying". I do all my flying and "stunts" total 3d. Meanining, any control inputs required on all 3 axis' I do from the radio with my thumbs. No mixing, no auto mixing from a switch throw. I always felt to do so was cheating and not actually flying the plane. Do the full size pilots just throw a switch for a needed stunt? Just the way I prefer it. After all, a knife edge is nothing more than level flight turned 90 degrees. If you can't do that in your mind perhaps you should stick to cars on the ground? Just the way I prefer it.

Mr. Mugen

I see....your stubborn. Thats ok.... I however am not. I can adjust to technology and use it to my advantage. I can do a knifeedge with no problem but making it easier to trasition to another move is helpful. I don't "need" it but prefer it. So in your mind I am not flying it....I can deal with that. However I did not ask for advise on how to fly with a flintstone radio. Just a simple how to with a mix. BTW if you don't use mixes then why try to answer? Applause for your awesome pilot skills though.

I asked about my thoughts on another forum about what I said earlier. It seems the majority don't agree with me. That's fine. Every one has their own way of doing things. I always said, "if we were all the same the world would be a boring place". And perhaps as I advance in skill maybe I will change my mind. I guess I may have learned too much from my teacher. He always flew it as needed and didn't worry if it was trimmed right or not. Just held in the needed correction all the time. I kind of questioned it at the time but it worked for him.

And I apologize for the car on the ground remark, that was out of line.

The important thing is that we have fun and enjoy the hobby. So keep flyin" and have fun.

Mr. Mugen

It's all good man. Take care and keep the nose out of the dirt.

So has anyone come up with a definate CG location for this bird?

Rick

Tesla1856

My recommendations are:

95mm for sport flying (and maiden if new to this size/type of plane)
100mm for 3D flying

The heavier nose makes the elevators less sensitive (less extreme)

I put an Irvine 60 in mine (about 1.8bhp) with a BCM Pitts silencer.
I used a Perry VP20 after a while because the pressure nipple for the Pitts was at the bottom and the engine kept choking on its own snot after a few minutes.
Scale manouevres were fine but it wouldn't hover. I needed to move the throttle servo forwards to get it to balance, so I gues with a 90 or 120FS it would be about right.
Landings were quick and I used -35% exponential in pitch and roll otherwise it was very touchy around neutral.
Model 1 damaged by a muppet in the pits in a taxying accident.
Model 2 didn't fly straight at all and I think there was a warp somewhere that I hadn't spotted. It dug a smoking hole before I could investigate!

I picked up the edge 540 and installed an evolution 1.00NX in it, but I have not had a chance to fly it yet. The wind has been terrible here!! I'm going to try the CG at 100mm for the first flight. I'm hoping the evo 1.00NX pulls this bird well.
