RE: *Seagull Extra 260 90 ARF*
Thanks, I'm leaning towards the 125 also, plus trying to gather info on the aircraft weight, understanding the wing loading concepts etc and I already have a Zenoah G20ei just sitting around now...

RE: *Seagull Extra 260 90 ARF*
Hi,
I didn't get any feed back on this question when I posted it before. Since then I wrecked the 260 (battery failure, my fault) but I have bought another one and I'm starting to build. It's going quicker since a lot of the hardware is already together.
Question:
I’m just finishing the Extra 260 and realize that the canopy doesn't fit. The front bottom brace hits the fuel tank. Did anyone have this problem or did I do something wrong. I fallowed the manual and the tank seems to be in the correct location. My next step will be to cut out the front bottom brace so it will clear the tank and figure out a way to reinforce it.
The new plane has the same problem. I called and left a message with Horizon Hobby product support, they must be very busy this mornig.
Does anyone have any input.

not alot of build info in this thread other than the balence issues with these planes. however after a long sleep in my basement ,i opened the box for the first time today and started my build. i used west system epoxy and coated the engine box and landing gear area both inside and out as is standard now with my ARF builds. i then ironed the coverings and did all the CA hindges. all were very easy with this model and things turned out as hoped for. i have other 3D planes and what with the wieght of this bird i am going to set this up as a swoop and loop beast. i am sure it will hover but with flat tall feathers i believe it will do best in"above stall speed" mode. she is about the same wieght and sq. in. as my H9 P51that i enjoy flying very much. but this bird carries a bigger engine so i am goimg to maximize my bird for speed! i believe she will be alot of fun to fly this way!

I have this model with the Saito 125 installed
3D performance is a bit heavy, but I like it. Hovers rather well too.
Mine weighs in at just under 4Kg(9lb)
I've just finished building it's bigger brother the 71" 160 size version
The build quality and finish is also excellent
This with a CRRC 26i gas engine weighs 5Kg(11lb)
Not flown this one yet
I really love my 90 size version and hope to love the 160 size as much
I'm sure you'll like yours as well
I have some build pictures of the 160 version, which I might put up sometime

Awsome thank you for the input, do you think the plane will fly well with the OS .91 FX motor?

Mine is complete, but while breaking in my newly rebuilt Saito 125 it threw a rod so had to send it back o Horizon. What CG are using for 3D with this set-up? Thanx

I've tried the CG between 6.5cm to 9.5cm (2 1/2" - 3 3/4" ) starting at 7.5cm
My current CG is just over 8cm (3 1/4" ) and APC 16 x 4W Prop
I find adding a 25g weight in between the stab supports is easier to prop hang
I really haven't measured the CG at the fuselage, but I think, going by other posts somewhere it's about 14cm (5 1/2" )
The manual says 7-8cm at wing tip

If you want to find the CG at the fus, assemble the wings to the fus then attach a string to one wing tip at the CG and pull it tight to the other wing tip CG. Any where a long the string is the corresponding CG.

RE: *Seagull Extra 260 90 ARF*
I just finished mine this evening . Installed a ASP 1.20 fs.and was a little concerned with the extra weight. By careful placement of battery and electronics was able to keep final weight at 8lbs 15oz. Also using7.5 cm at the wing tip for a CG starting point.
Was unsure of using the ASP 1.20 , this well be the first I `ve used it . Bench ran it with a 15x6 and seems to have lots of umph . I do like 3D as well as pattern , not big on hovering , but like inverted harriers and want to be able to pull out of a tight spot , if needed. Does anyone have a Magnum or ASP 1.20 fs on one of these ?
Generally I build kits . But at a $179.00 , cannot build it as cheap and it`s a decent ARF . And they really used glue on it . Liked the 260 so much , I ordered the 540 Edge .60 , should be here Monday .
On the 260 I used JR821`s digitals on everything but the throttle , which is a stardard BB servo .and 1650 ma. 6 v. battery . Will 88oz. torqe on the rudder be enough ?

RE: *Seagull Extra 260 90 ARF*
I have the Futaba 3152 digitals all round and a 3001 on throttle
The 3152 is about the same spec as the Jr821 at 5kg / 4.8v and about 6.4kg / 6v, which is 88oz in/6v
I'm using a 2s Li-po and 6v regulator for power
I find the 3152 adequate for rudder but slightly spongy
But not having tried a stronger servo for rudder, I'm not sure if it's just the way the rudder is on this plane
If you're into hard 3D, then a stronger servo for rudder would be better
My 2s 2200mAh Li-po / regulator is good for 6 x 8mins of hard flying, using about 1500mAh from battery
I would definately NOT use a 'AA' cell pack on digital servos doing 3D
Do not use thread lock on your JR821 servos!!! it will make the spine brittle and snap

RE: *Seagull Extra 260 90 ARF*
servos are now in and i have gone over every joint i could reach CA. as i work on this plane i am impressed with the quality that this ARF seems to have. sure it is a little heavier than some of my other builds but the wieght seems to make for a nice robust airframe that should give nice long service for grass strip flying that i do. it just seems to be a nice meat and potatoes plane. still about 90 days till the flying season around here. i can't wait!
