RE: Seagull Models Edge 540
 

Hi RCB, I can't tell you anything about the Vector Flights Edge but I do own the VF 66" Extra 300 and as soon as I get my P-47 and
P-51 finished up I want to get the VF SU-31 and put my Super Tigre 90 with the Davis diesel head in it so I am very happy with Vector Flight products. The Extra is a nice plane and the company has top notch customer service. I am waiting on the brown truck to bring my servos to finish up my Segull Edge. I hope I have better luck with the Edge then some of the people that I have read about on here.

The stab on my Razzle felt weak when I put it together...so I braced it...maybe that's why I never had that problem.

Upon inspection on my Edge wing (after it folded), the wood quality was poor. The wood inside the covering was warped...like the wood got wet sometime or another. I'm sure that's why it folded...and I'm still really steamed about Horizon not doing anything about it. Another person in our club had a wing fold on another Seagull Edge...same thing, wood was warped inside the wing. Weird thing...they came from different suppliers. Horizon also ignored his email as well.

RE: Seagull Models Edge 540
 

steven04 I have had nothing but good luck with Horizon! I have even had a Trainer replaced from them! He even through in a JR T-shirt! I have even had some work done to a Saito 100 that had been lost in a bean field for two months. Give them a call 877-504-0233

RE: Seagull Models Edge 540
 

I just cut into the wing on my Seagull Edge to see how the thing was designed. I was going to add some color to the bottom of the wing anyway so it wasn't a big deal to take a look. It appears that the wing joiner box is not part of the spar. Most ARFs use the spar for one side of the wing joiner box so you are, in effect, splicing the two spar halves together with the joiner. In this case there is a separate box for the joiner. So the spars would be held together by a butt-type glue joint where the two root ribs are glued, but no connection is made using the spars. I think I am going to cut into the root ribs and add another joiner in the space between the joiner box and the spars. Might be able to just slide some hardwood dowel rods in at the top and bottom to join the top and bottom spars This will add a little weight but I will have a sort of parallel set of joiners to connect things. The joiner box only goes to the edge of the sheeting so it isn't very long. A fast dive and hard pullout could cause a wing failure. Sort of a scissor type of hinging between the joiner box and the two spars that are only butt glued. The wood looks as good as any I have seen, but the design is lacking.

RE: Seagull Models <span class=
 

If you buy any model plane built by another person, you are taking a gamble.

RE: Seagull Models <span class=
 

I cut farther into the wing this evening. They tried to couple the joiner box to the spar by gluing an insert between them. However, the insert is not a tight fit nor does it have enough glue to tie them together. I put 1/16" plywood in the gaps and squirted the whole thing full of CA. Tomorrow I will epoxy the sheeting back on it to help fill in some more. Then I will join the wings and fiberglas the wing center top and bottom. I'm not sure that glassing on top of the sheeting without gluing the inner parts together will do much as there is a gap between the sheeting and the box. Won't really add that much weight. I will say this, they used shear webbing all the way out on both sides of the spars, and it is some hard balsa.
I may lose it the first flight but that's OK. I just wanted to try one. We have a wide open field and plenty of plowed ground to put it in. Just won't buy any more Seagulls.

RE: Seagull Models Edge 540
 

So let me get this right. Out of all of the Seagull EDGE 540 planes bought and flown, there have been a few that had poor,shotty,questionable,construction. Not all will be built the same, just like a Computer. I have one of these planes and plan on flying it this spring. If it dies, then fine. IT DIED. There are other planes and MFG out there to take my money.
I will bet you that there planes crash just as well. So a few bad planes got out, it sucks but there just isn't much we can do about it.

RE: Seagull Models Edge 540
 

Just wondering what torque servo's do you guys use for the various controls? I only want to know what is required and not overkill. I will be getting one of these as my next plane and as hi torque servo's are very expensive here I wanted to make sure I didn't get really powerful servos that are may not be required.

RE: Seagull Models Edge 540
 

Im using Hitec 605's on Ail. Elev. & Rudder, and a standard 148 Futaba on the throttle.
Should work great for you.
NEDYOB

RE: Seagull Models Edge 540
 

Grant ed,

It depends on what sort of throtle management you use

I'm using hitec 645's all round (I orginally bought em' for my 72' Katana), but the reality is that as long as your rudder servo is high torque and you don't do full power dives and pull up on full elevator, the others can be standard on a 6v flight pack as each surface has it's own servo. I reckon something like a hitec 422 would be fine.

RE: Seagull Models Edge 540
 

I flew mine for the first time flew good for the first test flight no trim needed I only did one or two snap rolls and a knife edge the wings stayed on so did the elevator I did't fly it much two or three flight but in knife edge flight I could not keep it going straight wanted to go the ground I have a hitec 5925 digatal servo and pull pull may be a little nose heavy ? not sure I have a saito 100 in it also I could not get it to

RE: Re: A FEW MORE QUESTIONS
 

Ok. I have read about 15 pages and I'm tired so I am going to skip the last 7 pages and just ask away.

I have had about 10 flights on my Seagull 540 Edge, and I have a .91 OS FS on it and I think it flies great.

My problem is with everyone talking about the servos in the rear. I want to know how I am supposed to make the two elevator servos be equal when the rods are of different length. I don't have lots of money to throw away at new servos and a new something to fix polarity and all that other crap. I want to know the cheapest way to get two elevator servos to behave equally as one.

I will give THANKS in advance. I appreciate the responses. I look only to RC Universe to solve all of my flying problems, and for that I am greatful. Thank you again.

RE: Seagull Models Edge 540
 

Hey, come on. I have a OS .91 Surpass that turns a 16X6 at 10,000 RPM. So why does anyone want to use a 2 stroke with less torque? I hear so much about the Saito 100 and the big two strokes. I haven't heard much about an OS 91 Surpass. The new ones really pump out more power! You guys should try it.

RE: Re: A FEW MORE QUESTIONS
 

Hi:

Computer radio:

1. plug 2nd elev to an unused channel.
2. slave that channel to elev
3. adjust elev clevis so both are level.
4. deflect full up elev and adjust endpoint on slave channel so they are equal
5. do the same for full down.


No. Computer radio ( expensive ):

1. get 1 hitec digital servo with similar spec to one of your elev servo.
2. program servo speed and endpoints so both elev halves travel same amount.

RE: Re: A FEW MORE QUESTIONS
 

Thank you redzo6. I have a computer radio and was trying to master/slave the elevators last night. I'm not sure what radio you are familiar with, but I have a Futaba T6XA, 6 channel. I have used 1 and 6 for alierons. I'm trying to use 2 and 5 for elevator, but I can't get the GEAR function to go away on channel 5. If any Futaba owners have any suggestions out there please let me know. I would much appreciate it.

RE: Seagull Models Edge 540
 

I flew one of these owned by another club member and it was awsome. I don't think that the aeroworks edge can be $100 better.

"Fat Free" Seagull Models Edge 540
 

Hi:

This is one awesome flying plane at $175 PERIOD.

I was amazed at how well thing thing glided in on maiden flight as if it was on glide tractor beam.

My initial setup was;

Initial weight: 8lb 11 oz.

OS 91 FX W/ Slimline Pitts.
4 Hitec HS625mg, 1 Hitec HS311, 1 Hitec HS645mg
5cell NiMH AA 1800mah Battery
No Wheel Pants
Spin Right 2 3/4 Aluminum Spinner
APC 14x6 Prop

Because it flew so well, I've decide to put it through a serious diet to increase it's low speed performance even further and of course better vertical (you can't get enough).

It is currently at 7lb 2oz. Have not flown it yet (can't wait).

Changes are;

1000 holes in fuse ( exaggerated )
replace LG mounting bolts / blind nut ( 1.5oz ) with 2 #8 screw and blind nuts.
change landing gear with one from Funtana. (3oz savings)
800mah 6V AAA NiMH pack. ( 3.1oz savings )
switch to dubro 2 3/4 spinner ( 1.5oz savings ) - Tru-Turn 2.75 with lightened back plate on its way ( another 0.5oz savings )
TF wood prop ( 1.5oz savings )
2 elev servos to HS-85 mighty micro (1.8oz savings) - I may have to move up to HS-225BB mighty minis

lighten cowl ( 3.5oz savings ) - originally 7.9oz
lighten canopy (4.5oz savings) - originally 8oz

As soon as weather breaks ( 40deg ), I will be test flying it.

RE: RE: Seagull Models Edge 540
 

so, how did it fly?

Jerry

RE: RE: Seagull Models Edge 540
 

Jerry:

No break in the weather yet. We've been in 20's for past 10 days and no break in sight.

RE: Re: A FEW MORE QUESTIONS
 

If you haven't figured this out yet, go to the travel adj. menu and zero out
5th channel . The 5th channel will now follow your elevator channel travel.

Stick2k;)

RE: RE: Seagull Models Edge 540
 

I am still considering the following engines for the Edge 540T.

- Saito FA 100
- OS 90 FX
- SuperTigre G90 Ringed 2 stroke

I am still undecided between a 2 stroke or a 4 stroke. Any advice ?

RE: RE: Seagull Models Edge 540
 

Hey Born:

Makes no difference wether you use 2 or 4 cycle as long as you use equivalent displacement.
I believe that this plane is happy at 23oz max power plant including muffler.

U should consider using 91 2stroke or 120 4 stroke as a power plant.
However, this plane would be happier if you chose one under 23oz including muffler. This sort of eliminates all 120 4 strokes.
You can use saito 100 ( around 22oz ) but you won't be happy with the performance unless your plane comes in at or around 7lb.

It all depends on your style of flying. If running out of steam on upline does not bother you then saito 100 is ok too but if you are like me, then you will not be happy with it.

That leaves only OS 91 FX. How about OS 1.08? You have to carry extra weight penalty which hurts low speed performance.
Stick to OS 91 FX and see how it flies. If you are unhappy with upline or slow speed performance then lose some weight instead of adding heavier motor.





If anyone bought Seagull Edge 540 60 size and have a digital scale, please report your cowl ( uncut ) and canopy weight.
Mine was unnecessarily thick ( I image the cowl will survive a crash when rest of the plane wont at 8oz ) and I would like to know if there is a variety that weigh less.

RE: RE: Seagull Models Edge 540
 

I don't have a scale, but I can tell you for the most part my cowl survived my crash when my wing folded...plenty strong indeed..

RE: RE: Seagull Models Edge 540
 

Guys,
I am building one of these. I was wondering how far away you are mounting you .91FX from the firewall. How far out to the back of the spinner. Thanks. Bruce
