I currently have a modified SIG Four Star 60 with clipped wings and a ST 91 up front. It is very fast and very aerobatic. Most importantly it is built like a tank. I am considering getting the Seagull Edgev2, however, I am a little uncertain as to whether it is sturdy as I've read posts where the tail will come off. Any opinons from people who've had the version 2 of this bird would be appreciated.

My most important question is what size 2 stroke engine can I put on it. I have a ST 91, and it pulls the Four Star around good. The 4 Star weighs around 6 pounds. What would be the max size engine to put on the Seagull? No Four Strokes.

We have the V2 of the Edge 540 and I think it is as good as, or better than, most ARFs in the sturdiness stakes. (You've probably been spoilt with the sturdiness of the SIG though - IMO, they are excellent when it comes to strength). I heard about the tail issues and as we tend to 3D a bit, I recently fitted some better tail wires to it. We haven't had a problem but I felt it would be better to be safe than sorry.

Ours is currently fitted with a Saito 1.25 which, being a 4 stroke you are not too interested in however a couple of my fellow club members also have this plane fitted with 2 strokes. One had a ST 91 in his and it flies it OK but I think it is marginal in the power stakes. Another Club Member has an Evolution 1.00 in his and it flies it pretty well with no problems when it comes to 3d'ing and vertical pullouts. The third one has an OS 1.20AX in his and it has more than enough power for anything - including "unlimited vertical".

OK. Any other fliers have a 1.20? I like the big end of the power range.

If I was doing the Edge again, I would go with the 1.20 AX, I had the Edge with the OS1.08 and it flew very good.

Hey Guys,
I just bought the Segull Edge 540. How do I tell if it is a version 2?

Thanks
Mike

Easiest Way - Look at the color scheme - if it has a lot of yellow - it's a version 2, the wingspan is also bigger on the version 2 (by memory 68" instead of 67")

mshick

Hmmm - mine has yellow striping and the box says the wingspan is 68.2. So what do you think?

Thanks
Mike

Mine looks just like this: http://www.horizonhobby.com/Products...ProdID=SEA4000

with the same dimensions listed

That's the V2!

mshick

Thank you Sir! Just got it out of the box and the quality looks pretty good. Anyone using the stock motor mount. I'm not sure what material it is but it's a blue color.

Thanks again!

Most of the people I know use the stock mounts from the Seagull kits - they work fine.
I'm using a Sullivan mount on mine because the stock mount didn't fit the Saito 1.25 too well. Depending on how hard you want to thrash it around, the standard hardware is OK too. If you want to "3d" it - upgrade the horns and linkages now.

Saito 120 in mine, not quite enough power, Saito 125 or 150 perfect, nothing less than a 120 2 stroke. Also bent the wing tube when I did a real hard blender. I am replacing it with carbon fiber. Other than that good airplane.

I bent the wing tube in My Version 1 - All I did was deadstick during a flat spin and the tube got bent at around the same time that the wood splintered

Anyone flying this plane with a 61 size engine? How does it fly as far as general sport flying?

Thanks

Mike,

I have a Magnum 91 2 stroke on mine and I like the combination. My servos are mounted mid ship in the cabin area, and I have needed no additional weight up front to balance. A strong 61 will have the same weight as my engine, with less power. I use a 15X6 prop on mine with good result, I would use a 13X6 prop on a 61. You can see there will be a big power difference. The plane will probably fly on a 60 (mine takes off at 1/2 throttle) but it will have limited performance, surely not near the capabilities of the plane's design.

My set up is not "3D", but it is very able to fly aerobatically to my liking.

I know this plane is advertised as a 60 size, but I don't think it will be a very happy combination with a 61 engine. I see a lot of postings where people put way oversize engines in this plane, and I guess it holds up for them.

You might try it with a 60 size engine and upgrade it later if you find the 60 "not enough". Good luck!

Mine's one of the ones that is "overpowered", It 3D's pretty well but I am cautious about keeping the top speed through maneuvres (Currently running a 16 x 6 APC prop). I usually manage to "end the life" of my planes due to dumb thumbs instead of through mid air breakages.

another guy at my field has a 61 in his v2 edge. for sport flying its ok. very little vertical capability however, but flew ok. i flew it myself. flew very light. i have a saito 120 in mine. slightly underpowered for my flying tastes. for good sport flying i would use a 2 stroke 90 and for hardcore 3D and IMAC use a 120 2 stroke. i flew mine in the Basic Class at a IMAC event this past Sept with the Saito 120 four stroke. Just enough power to due all the manuvers but would be much better with a 125 or 150 four stroke.

mshick

Thanks for the great info guys! I think I will go with an OS 91.

Thanks again.

What is everyone using for servos. For general sport flying I was just going to use the standard Futaba digital servo that came with my radio. Anyone using high torque on the evelevator or rudder?

Thanks

I'm using Hitec 475s on all flying surfaces and 425 on throttle, with a 5 cell battery.

aussiesteve

I'm using Hitec 5985 on the Rudder and 5645's on the elevator and Ailerons - a bit of overkill but fast and furious. I never have doubts about whether or not the servos are up to the job. I have a 5 Cell Pack and HS475 on the throttle. I use all Hitec gear and run this model from an Optic 6 with a PCM receiver.

mshick

Thanks Guys. Do you think the Futaba digital 3151's will be good. They provide 43oz of torque at 4.8 and 54 oz torque at 6 volts.

i use futaba 3010's(non digital) on all flying surfaces at 6 volts(.16 speed and 90 oz torque). they work great. digitals are always better if you want to spend the extra money.
JR 821 sport digitals(.15 speed and 88 oz torque at 6 volts) are only $25 a piece( at my LHS) and would be great for this airplane if you want digitals.

I have only seen or read about the tail or some part of the tail coming off twice. On both occassions the builder used a different tail wire material, or installed them in a different configuration. Stick to the manual and you should be fine.

I'm running a Saito 1.25.

(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.
