Seagull Models Edge 540
 

DUC, I actually own a TT 91 4C, which is why I said that it probably won't hover adequately if the plane is 8# or heavier. Mine is on my 7# UCD3D and it hovers OK. Nothing to write home about. An 8# plane may hover, 8.5# and you're probably hovering at full throttle, not a whole lot of room for error. 9# and there's absolutely no chance. Anybody know how much this plane weighs with a 26 oz engine? I'm going to go with an MVVS 91 w/tuned pipe which can spin a 16x4W prop over 10000 rpm... That should give me the 2+:1 thrust to weight ration needed for good 3D performance...

f2racer:

wolf123 has this model with the TT and it is hovering. About the weight, you can look at post #147. The plane is on a scale and it is under 8 lbs. :thumbup:

From all the threads I read, it seems somebody mount the engine inverted and somebody did it sideway. So what is the origina design for the way to mount the engine. Can someone tell please.

I got a seagull PC-9 and have about 20 flights but the engine does not idleing smoothly because of the inverted engine. Once I started the engine I got be quick to get in the air, if I let it idleing too long then the engine will quit. That's why I want to know the way they mount the engine of Edge 540.

Thanks in advance.

you may mount engine in which way you wont,side inverted,upright,,,,etc
i 've side because this setup is fine for the position carburettor-tank, but if you place tank right ,,,mount it inverted.
btw which engine you use on pc-9?
i use a lot of inverted mount(majestic,g-trik,cap 232) but i never have problem.

For my Seagull PC-9, I use OS 46 FX with OS#8 plug. Because the high position of the full tank I can see the fuel flooding if I donot stop the fuel line,also I can not lower the tank anymore because the original design. Somebody suggested to use the on board glow drive, but I have not try it yet.

About 540 Edge, if the oringina design is inverted mouting and if you want to change it to sideway, then I supposed you have to re-drill the 4 mounting holes and work out the thrust line, am I right ?

Regards.

hi edward
mi edge have side right out of the box so i don't change any.

Thanks Wofl123,

That makes me feel more comfortable to get this Seagull Edge.

Thanks.

Anyone understand how to assemble the wheel pants without having the axle stick out from the other side?

cut it

Wheel pants
 

Hey Jerry
I cut mine off and used wheel colliers to keep it in place worked out great and even looks good when I put the decals on the wheel pants and there was no rod sticking out the side.

Seagull Models Edge 540
 

I think the way they show it.....well that's a VERY poor method - especially when you compare it to the rest of the plane (1St. Class!)

we hate them wheel pants but they look so nice.

I just bought the Seagull Models Edge 540 and I was wondering if anyone had any advice as far as the type of radio or engine and what is needed for construction what do they include and what do I need to buy. Thanks MUCH ALL

great - follow or search seagull edge right here and read the threads and you should find all you are looking for, enjoy!!!

Edge with SC 1.20 FS
 

Picked up my Edge on Sat, here's some pics of the SuperCustom 1.20 I got for it installed...

I took the choke carb off the back, that saved me a precious few mm! :-) lol

length of motor
 

This pic won't mean much to anyone that hasn't already got an Edge, but for those who do:

as you can see the cowl looks to fit ok with the long motor, the choke flap would have put it a long way forward but I think it will fit just nicely.

I changed the engine mount as the one that came with it had tiny bolts (I wouldn't use them on a .40 they were so small). Replaced it with some decent angle bolts and an Anderson adjustable mount.

Gricey:

Can you tell us the total length of the engine (back to front washer )?

GL

Seagull Models Edge 540
 

I'll measure it tonight and let you know. Any ideas what average thrust you can expect from something like this on a 16*6?

SC rate the engine as 1kg in weight.

Seagull Models Edge 540
 

:confused: Not really !

On the other hand, we have a Magnum at our field and that really is something extra :surprised . Do you have any idea of how fast your plane is flying?

GL

Seagull Models Edge 540
 

My Magnum (as seen in Avatar) has a super custom .53 with a normal muffler. I fly it on an 11*7 which gives it unlimited vertical performance (no joke). I tried it on an 11*8 APC but the vertical suffered and it didn't really seem that much faster in a dive.

Ireland is a very windy country, down wind in Winter (pulling out of a dive) it is ridiculously fast. I don't know that it's 200mph but it's definately sore neck territory :-)

There's no way you can check to see if there's anyone in your way, I find it best to fly when no one else is or else it's brown trowsers time.

I'll do a doppler shift calculation but it will be in a few weeks and will get back to you. I plan on getting another Magnum with West v50 in the next 2 months. Then we'll see some serious pace. :-0

Seagull Models Edge 540
 

The Magnum we have here has a Webra engine and it really has unlimited everything. Like you say, is better to fly it when nobody else is in the air.

Now, returning to the Edge...did you reinforce the wing ? What system are you planning on using for the rudder ?

Seagull Models Edge 540
 

I've been quite impressed so far with the quality and the thickness of the components used. The main wing joiner section is quite thick and is a glued sandwich of different woods. I guess this could be to give excellent vertical and horizontal strength whilst also mixing in thickness and being light? my guess anyway, I'm no structural engineer.

I compared it to a mate's Seagull Spacewalker II (yes it's only 40 size I know...) and it is about 3 times the thickness and feels very sturdy in comparison. I was thinking about doing a fibreglass wrap on the wing centre but I'll be using good quality PVA so I don't think just wrapping the centre will make any difference with such a good center joiner. I'd say if something breaks it will be in the wing section outside of the joiner.

I've yet to look at the tail section in any detail but what I did notice was that the tail plane seemed quite thick. I'll measure it later and post some stats. The rudder is a central rod that passes through the fueslage, a bit disappointing as on the box it shows a servo directly at the back and connecting to the rudder via a short push rod. I guess that must be for the 2M wingspan model. I won't be going closed loop. At the end of the day I'm just a club flyer and I think the extra cost and hassle involved probably won't give someone with my talents (or lack there of) that much extra.

Have to say though, it's a great model, very similar in finish to the Seagull PC9 so I think it should be ok...

Magnum .91 for Edge 540
 

Does anyone think or have they tried a Magnum xl .91 on the edge 540 63" wing. Thanks much all.

Hi Ducatti996,

here's the SC 1.20 measurements:

Rear of engine (inc bolt head) to outer of prop driver = 105mm
Rear of engine case (after bolt head) to back of carby = 25mm
Therefore absolute back of motor to front of prop driver = 130mm
Bottom of case to top of tappet cover = 140mm
Width of mounting plate = 70mm
Mounting holes centre to centre = 60mm

The Magnum 1.20fs should be similar to this as they are made in the same factory.

cheers!
