Default Seagull Models EP Extra 300

http://www.horizonhobby.com/Products...ProdID=SEA7000


Brand new and off the shelf from the looks of it. Does anyone else have one yet? Just picked one up after opening the box, quality looks unbelievable.


I'll get some pics soon, going to be using th 480 outrunner and 2100mah lipo's to start with. Control surfaces are huge

I got mine a few days ago. Mostly built, just waiting on some servos. This one should be a pretty good one. Looks great!

I am very curious about this model.

In the pictures on the website it looks "rough" Like on the leading edges of the main wing for example you can see the covering shrink inside each "rib" does youre look like that?

very affordable, might jsut have to give one a try.

I'm thinking of powering it with my kontronik maxi dancer 2.5oz motor, 21A, 40oz thrust from a 10x5E prop. and keeping it light. Possibly powering it with thunder power 910 pro lite 3 cells, 2 packs in paralel for high power usage and single 1320 3 cells for light weight. I used this setup in lighter aircraft with great results. Love the color scheme on this thing and the size looks nice too.

I got a chance to check it out yesterday. Looks like a really nice airplane. Im glad to see its got PROPER amount of wing area, unlike that little E-flite Edge.
I think a E-flite 480 (EDIT: yeah...oops...typo) would be insane amounts of power in it, looks like a really fun 3D bird.

The covering does "sink" in between the ribs, however this is not a mistake. The wings leading edge is not sheeted and that is why it does this. Not to worry though, it doesn't affect the flight.

I am using the Park 480, Eflite 40 amp ESC, with APC 11x7 E prop, TP2100 Pro-Lite. Berg Rx. I am going to maiden mine today, or perhaps tommorrow. I really like this plane and have it setup like the manual said. The only thing I am going to change is the landing gear. The gear is sturdy enough, but I don't care for the design of it. JMO.

Guys I couldnt resist. So I just bought one of these.

OH MY....

WOW what a plane. Ive never been impressed with the seagull models, but this thing is FANTASTIC. I think this is truly gonna be a winner. What a surprise.
Honestly this is on par with higher end micros like the Hyperion birds. The landing gears is a great design, but leaves me wanting more in the "asthetics" department.
Very clean, simple design. Very good classic extra looks. The covering is pretty good, tight, and clean. The turtledeck and aft cockpit deck is flawless....very well done.
I would recommend hitting everything you can reach with CA..it doesnt look like they even glued it.
The leading edge of the wing is just a stick of balsa, resulting in the odd stretched appearance of the leading edge. Its not really an issue unless your really picky, and really...you should be happy. It makes it MUCH lighter.
Im also extremely pleased to see a one piece elevator. No gluing reinforcements, elevator halves together, etc. Just hit the hinges with CA, and yer done.
Based on my initial views, I think they did some serious research with this plane, it seems to be VERY well thought out.

The cockpit design is probably the best Ive seen on any small electric kit. Super Secure latching system, Fliton and E-flite...take notice, Seagull did it right!... it even has the nice added touch of realism by them placing a full color instrument panel inside the canopy. Sweet.

Oh, and they also included a removable battery tray. Rubberband the battery to the tray, and then you can just take the tray in and out with one screw, vs velcro straps everywhere.

Wing area is generous, and surfaces are large, which should equal good 3D performance. I have a feeling that roll rates are going to be insane. LOTS of expo on this one.

The plane goes together in a very short amount of time. A single evening is all you need. Even the most newb pilot could build this in a evening. Piece o cake.

Here's the list of equipment I am putting in mine.
E-flite 480 brushless
E-flite 40A esc
VampowerPacks 11.1V 2250mah lipo
Hitec 05S rx
Futaba 3110's all around.


Looking forward to flying it this weekend.

Yup, I went in...looked at it....walked around, looked at it again....walked around...opened the box to check it out again....walked around....did a mental calculation of finances...looked at it again...and despite my best efforts at leaving the store without it...

I couldn't..

Im SOOOOOOOOOO addicted. I need help.
And to top it all off, Im closing on a new house right now, and the inspector and appraiser are at the new house right now...Im working on this new airplane.[X(]

Its like a mosquito being drawn to the pretty light....ooooooh its soooooo prettttttty...BIZZZAAAAAP.

Good news is I bought it at 12pm...and its 3 now, and all I have left is to program the radio, charge the lipo, and adjust the linkages and throws. I had most of the stuff laying around the house.. All I had to buy was two 3110 servos. Cant wait to put it in the air!!!

Go buy one...its a really cool airplane. About the same size as my Brio was, but I like this thing better. 100 times easier to set-up and assemble.
Its a really nice bird, especially for the price.

I really hope it flys as well as its gone so far. It was actually PLEASING to put together. Everything fit correctly, first time. No trimming, sanding etc.
Honestly, It has to be the easiest balsa built-up ARF Ive ever put together. It almost put itself together..I really had fun building it. The worst plane was the tensor...what a pain in the......

Its in need of some cool graphics though...gonna have to whip something up.
I hope Seagull comes out with a YAK, and a Edge like this. OH god...a edge in Kirby's Red Bull paintscheme...drooling just thinking about it. Thats like my dream plane...a 40% composite-arf with the red bull scheme.

I maidened mine for about 5 minutes this morning and it flys great! KE's good, hovers no problem, didn't really have much more time to really put it thru it's paces but it was sweeet! Some of you may not realize that this plane has what I would call torsion bar landing gear. The gear under the fusalage actaully twists and allows the LG to move rearward if an impact occurs. Truely revoltionary!!! This one's a "keeper"!

My setup:
E-flite 480/910 Kv
APC 11x7E
TP 2100 Gen 2 (yellow stripe)
HS 55's
HS 65 on rudder
Phoenix 25
Electron 6

Hey Jimmy,

did you follow the manuals recommend throw rates?
The manual says 3/8" on elevator on low rates...that sure doesnt seem like enough.

bdavison,
No, I put in slightly more than is recommended for low rates and for high I always go for max (on 3D planes) regardless of the specs.

Well, I went with the manual recommended throws, and it cost me. DO NOT FOLLOW THE MANUALS RECOMMENDED THROWS. If you do, it will crash.
3/16 on ailerons as they recommended will result in ZERO response on ailerons, and the 3/8" high rates are a joke. They too are insufficient.

You need 1/2" low rates, and 1" high rates on ailerons, about the same on elevator (but with expo), and rudder...well I fly with full deflection in all modes (I like rudder, and tons of it)
I CA'd it back together enough to get a flight out of it. It was flying great, about mid-flight, the horizontal stab snapped in two (it was damaged from previous crash) I literally had a V-tail, and the right horizontal stab and elevator was flapping like wings on a bird. All my friends thought it was a done deal. OH no...I was determined not to lose this bird. With the horizontal stab folded I actually brought it around, and set it down in a perfect three point landing smooth as glass. All my flying buddies were looking at me with their mouths hanging open. One of the guys said he wished he had that on video, because no one would have believed it. It was a miracle.

I didnt tell them, but honestly, It was still controllable surprisingly. I had a reasonable amount of elevator control even with all the flapping. I think they were more puckered than I was.

I took the broken hulk back home, and cut the broken horizontal stab out, cut the covering off the wings, rebuilt both wing tips,straightened the wing tube, built a new horizontal stab, and recovered it to match the original color scheme. You cant tell it was ever busted up except for a scuff on the cowl, and the Red is a little off shade.

Now...on to the flying ability....

WOW WHAT AN AIRPLANE!!! This thing flys 100 times better than ANY of the other planes in this size range like the Mini Funtana, Mini Edge, or even the Brio.
Dont worry about it not slowing down. Even at 26oz, it floats like a feather. I was absolutly shocked at how it floats. Coming in for a landing is fantastic. No odd stall charectoristics, no wing rock in harriers. ROCK SOLID. It hovers great. Almost like hovering a foamy. Spins are good, but do require slight opposite controls for exit. KE has a little pull to canopy, but nothing that cant be mixed out. Inverted flight is smooth, and neutral. If you program spoilerons into it, it will do GEORGEOUS perfectly vertical harrier/elevators.

I love the plane. It flys as good as it looks. I HIGHLY recommend this thing to any of you guys that are tired of the poor flying planes this size. Its fantastic.

Here are some post-mortem pics after it is all repaired.....and yes the horizontal stab is now SOLID, instead of built up. The elevator is however still built up.

I couldn't have said it better myself. Today I explored Blenders and this thing is a blender machine! Getting into and out of them is a snap. It KE's great also with NO detectable coupling. I may have been feeding in a hair of elevator but nothing noticable. I certainly don't need to mix it out. This could possibly be my best flying plane and I'm not just saying that because it's new! Comming down in an inverted elevator it just floats, a touch of throttle will easilly slow and /or stop the descent.

built it, flew it, love it.

setup;

ailerons have crappy dynam servos to be extracted asap.
elevator and rudder use d47 dymond servos; perfect.
motor; Kontronik Maxi dancer (2.5oz or less... conflicting info some say 66 grams some say 73)
castle creations phoenix 25
thunder power 1320 pro lites
berg 7 (new by cc) rx
deans micro connectors
10x5 apc E prop
auw= hard data to come soon due to scale limitations, but F%$#NG light!
vertical; unlimited! climbs at 50% throttle.

Only 5 flights on it and from the second one, after a couple of tweaks here and there i was at ease doing harriers with the tail dragger scraping on the pavement, that's how good it is. (and i have allways been terorized of balsa models and how easy they break vs how hard they are to repair/re-skin. In spite of that thought i am doing inverted harriers right on the deck with full confidence.

I tried balancing my seagull extra tonight and it came in tailheavy. The manual says CG is 5-6cm or 2 - 2 3/8" from the leading edge. Is this where you guys are balancing yours at. At 2 1/8" back the nose required 5oz of weight..

Ha all/read through previous posts.. glad you guys are having good results during violent maneuvers. unfortunately i had an inflight failure about 2 minutes or so into my 1st flight today. its ironic that i had noticed some potential week spots and also suggested some quick fix's for them.. i should have taken my own advice. being the skeptical natured person i am and also the fact that i like testing things etc i decided to push the extra 300 a little harder today/theres several things that could have contributed to this failure. i in no way consider it the manufacturers design or qaulity.. both are high in my opinion.

Factor 1: i was flying on higher than suggested rates.

Factor 2: i was flying a down line at a fairly high rate of speed

Factor 3: i opted for dubro micro hinges and my ca might not have bonded properly.

Factor 4: i was flying into considerable wind on the down line

Factor 5: near the bottom of this down line i pulled up a little more abruptly because i was around 10 or 15 feet and wanted to level at about 5 to 10 feet for pass.

i discussed this with my local shop owner and he inspected the plane.. he suggested asking seagull for warranty on a new stab and elevator/im considering this but i dont believe the planes design is at fault.. whats at fault is my flying style and surface throws.. and posibally my ca joint and ca. i'll have a follow up part two on this. right now im thinking about the repair and what will keep this from happening to pilots that are more expierenced than myself who may be pushing there extra 300s harder than i have.. ive been fairly vigilant to look over the airframe after my flights on this plane because of my initial concerns and until today flying fairly conservative in my opinion. i picked up some materials for the repair and reinforcment of mine. i may just order another stab and elevator and reinforce it rather than fix this one.. the repairs will not be that extensive. for others heres some suggestions.

1: carbon fiber strips across top and bottom of elevator to make both sides more rigid.

2: carbon fiber rods attached from below stab.. possably on the top to

3: this one is optional.. fly the plane as intended and marketed.. aerobatic plane with low throws(i know its hard with this one not to wanna 3D it)

hopefully this helps and no one else has a tail failure.. maybe i just had some bad luck. i'll have mine in the air again soon i hope. it would have been nice to have got this on video.. even with a brisk crosswind and half an elevator i managed to get it down in one piece with a fairly decent landing all things considered (i must be getting better at flying these things)

the manual states cg to be referanced from wing tips/not wing root. this has created quite a bit of confusion for some.. theres about an inch differeance just by eye between wing root cg and wing tip cg/try cg back about an inch. id provide the exact cg marks at root but my calipers battery is dead. sorry about low qaulity pic.

Yeah, put your fingers below the black stripe. It should balance there, or with a slight nose down attitude. If that works...your ready to go.

Just keep it somewhere in the black stripe and you'll be ok.

Default RE: Seagull Models EP Extra 300

Ive got about 7 flights on mine now. Its a spectacular plane. Really flys well, and fun. It will do 3D stuff.
Here's the set-up as I have it now

Ailerons
1" on low rates with 40% expo
1 1/4" on high rates with 40% expo

Elevator
1" on low rates with 20% expo
2" on high rates with 60% expo

Rudder
2" on low rates with 30% expo
2 1/2" on high rates with 45% expo

All measured at the farthest trailing point of the surface. For me this is pretty close to perfect for the plane. On low rates, it has precision performance for flying scale aerobatics, and on high rates its good for 3D. Here's my tastes in how I determine the specifics of the throws. For ailerons, in low rates I want a 360 degree roll in 1 second. In high rates, I want it to be just enough to slowly anti-torque roll in a hover. For elevator in low rates, I want smooth round loops, and pulls to vertical. I dont want it to swing the tail out if I pull to hard. In high rates, I want it to swing the tail out from under it, and I want lots of expo so Im not over controlling it. Rudder. I love rudder...and lots of it. In low rates, I want enough to do KE, and if I jam throttle to it, enough to climb in KE. In high rates.. I like enough for a KE loop, or if I slam it to the stops, I like the plane to swap ends.

One other thing...I found out this plane WILL do climbing flat spins. Fly straight level flight, now jam full rudder and opposite aileron and then full throttle. If you time it right and get just the right amount of aileron at the right time, It will go into sort of a climbing flatspin. FREAKIN AWESOME. You may need a touch of up elevator to start climbing. I got to get video of this. Its insane.
