(4) Futaba s3010 ailerons and elevator
(1) s3305 for rudder
(1) s3004 for throttle

Excluding the throttle ... all servos should be high-torque, and even metal gear as needed. It kind-of depends on what engine you choose and how hard you are going to push the air-frame (and control surfaces).

Those 3151's are digital so I don't know but some guys used some similarly torque rated analog ball-bearing s3004 for all surfaces on some of the first Seagull v.2 Edge 540s and they were stripping gears and losing servos in flight. I would rather spend a few extra bucks for some "insurance" or performance buffer.

I got the OS 1.20 AX and the problem is that the included stock fuel tank is only 300cc. Would that be enough ? anybody moved with this setup ? any suggestions about larger fuel tanks ?

300 cc is only about 10 oz. Not a lot of tank for a 120 AX. I think i'd want at least a 14 oz. I'm putting a 16 oz tank behind my YS 110 in this plane.

I have just finished my edge 540 but not flown yet as the weather is rubbish,high winds and rain for the last couple of weeks.
I have fitted a Saito 100, Hitec Digitals, 5 cell nicad (4000ah) ,need the nose weight,also the rudder servo is amidships.
Any comments regarding performance with this setup might be appreciated!
The only bad comments I would make about the hardware supplied is the softness of the engine mount screws, I managed to strip them usung a medium crosshead screwdriver!

Jonseys,

Your setup sounds fine.

During my initial build I used standard thread cap head screws for the engine and used the longer metric set through the firewall and put metric nylok nuts on the back, up against the metric blind nuts. I did have a landing gear screw strip out once (also metric and same size as others).

42etus brought this thread back to life from 2006, but if you want, check out my original Edge 540 thread here:

You might also be able to pick up some tips from my website's build page (see sig. below)

I have te same plane and run a saito 125 with a hayes 16 oz. 2 line tank in it. I run JR ds821 all around except rudder. Which is the hitec hs525bb (fast servo)

the gear on the plane is junk. I switched to graphtec main and tail gear and a cf wing tube. I swing a apc 17x4W prop and the plane is an animal. Great flying plane and a joy. Does every maneuver with ease.
I also have not used hte elevator suort wires either. I wrung the hell out of the plane and anked full elevator from a full throttle 300 foot dive and it stayed on the plane. No cracks either. So I say they are uselss dead weight as long as you epoxy the tail feathers on liberally with 30 min epoxy your good to go.
Been flying with skis in it...

I'm curious which Graphtech part you used on your Seagull Edge. It looks like maybe the one made for the Aero Works .60-.90 Edge is a close match to the Seagull gear.

YEAH 60 TO 90 but, we are modelers. I can make any gear work on any plane as can you if you want to put the time in.

Fellers,

Is this the Hayes tank that you used? Did you have to do much 'modificaton' to the inside of your plane to get it to fit? Also where did you find the right size wing tube? Thanks?!

Yes that is the tank. I had to cut the side supports out and epoxy popsicle sticks a half inch out on either side of the tank. I screwed smal circle hooks to the fuse bottom on the side of the tank. I then wrapped tank in foam and used # 64 rubber bands to hold the tank down the fuse with the hooks.

I got the tube from TBM, TNT can help you to. If you can't find the exact size like I could not, get a very tight fitting dowel in the cf tube, chuck it in your drill and spin sand it to fit.
Talk to Bill at TBM troybuiltmodels.com any of the guys can set you up there. They are great experienced wise modelers! Can't say enough great words about them all and their top notch operation !

I have an evolution 26cc gas engine and am thinking about buying this plane, has anyone tried this combo yet?

It is a fairly strong airframe. If you reinforce it a bit I don't see it having a problem with that gas engine.

I have a Toro 25cc conversion I have been thinking about putting on my Edge. I haven't done so because I am too lazy to mess around with a good flying plane. Y'know, "if it ain't broke, don't fix it"? I would sure like to hear what you think after you get yours together! You might consider it a public service!

I am presently using a Magnum 91 XLS 2 stroke. So, I think you should go for it and report back.

A public service indeed it would be. I have a few smaller cc engines I have been wanting to try. So this plane would be a great candidate. Do it up and give us step by step brother.
I was just looking mine over and to be honest I don't think you really even need to reinforce it. Triangle stock is already fore and aft of the firewall on mine and the rest of the fuse is rock solid. DO it man. If this works out all my small planes will be smaller gassers. Nitro to darn much, lol...

I am still considering on buying the edge and installing my 26cc gasser in it, can anyone give me the lenth from the center of the prop shaft to the ground as I will be using a 16 or 18" prop on this engine.

thanks
mike

The shaft to ground distance on mine is 10 5/8" with the H. Stab level. I run a 15" prop, another flyer in my club runs a 16" (1.20 4 stroke) on his. 18" prop will probably work, but I haven't seen one in action on this plane. Of course, the kit wheels are replaced with 2 3/4 or 3" wheels.

I run a saito fa 1.25 with a 17x4W APC prop. I have 3.25" wheels and have good clearance.

[img][/img][img][/img]a friend of mine put a supertiger 90 2 stroke in his with a 16/4w prop and flies it just fine. I got a 540 edge for christmas and have a choice of engines i already have 2 strokes, 61 rossi, os and ervine, 1.08 os, & a 4 stroke 91, & 70 os, or buy a supertiger 90 , for the money and 3 year warrenty its hard to beat.what do you guys think.

Haile, if you want crazy unlimited sky tearing power, the OS 120AX is the way to go, use an APC 15x6 prop and mount the muffler in the pitts style and remove the internal baffle to have great roaring sound. All other engines are a compromise ! and I would definitely never buy a supertigre, it is cheap and you get what you pay for, after 3 or 4 gallons of fuel it will start loosing its punch very visibly, the needle will become hard to set and the engine will start dying in flight more and more frequently.

Hey gus,
I bought my Seagul Edge 540 V2 when they first came out. I have had NO PROBLEMS with this airplane. I used a HiTech 645 Servo on the rudder and HiTech 638s for the elevator and airlons For the throttle I used a HiTech 225. For power I used a YS 91AC and aan APC16x4 eide prop. I had to add about 1oz of weight to the nose after moving my 4.8 volt 1400mah Nicad as far forward as I could. While I am not into 3D I found that the YS 91AC had plenty of power for all the normal pattern manuvers. I was ablr to hover but pull o a fuel hungry YS, I really like this plane.

Gentlemen, After reading the thread I am still confused on what servos to purchase. To start out I will admit I am a Pilot First and just barely a Modeler. Modifications will come few and far between. That being said, I have purchased an already built Seagul Edge 540 V2 and a Saito 125 for the powerplant. I was told that the airplane does not like hard landings so thanks for the Gear information but I would love to know if there is a bolt on set out there.

As far as Servos go, I would like to get some suggestions for reliable servos that will not break the bank. That being said I would like to do it right the first time. I am a Futaba man in my heart but will take suggestions on any brand.

Thanks

Look back in this thread a bit (or visit my website) and you will see what I use.

I used Hitech 635 servos on the ailerons and elevator and I used a Hitech 645MG servo on the rudder. For the throttle I
used a Hitech 425 BB servo. That should take care of the servos. As for the landing gear I would check with TnT and see what the have to offer. I hope you enjoy your Edge 540 as much as I enjoy mine. By the way, I am using a YS 91AC in mine.
