Default SPACEWALKER ll 40 BY SEAGULL - GAS TANK PLACEMENT

Just got a SPacewalker by Seagull [link=http://www.horizonhobby.com/Products/Default.aspx?ProdId=SEA2050]SEE HERE[/link]
and Im having troouble deciding how to install gas tank... Ive looked at the manual s picture (barely any directions and one incorrect picture that doesnt look like mine when I put my tank in), looked here on the Universe ( found nothing) and called Horizion
( which was useless)...boy I think less and less of horizion every time I call...but thats another post...

in any event, I did find [link=http://www.findarticles.com/p/articles/mi_qa3819/is_200408/ai_n9433822]THIS[/link]

which basically states....

The supplied fuel tank has a concave back, so be sure to cut your pick-up line to the proper length, or it won't be able to move freely in all directions. Which I have no idea what he's talking about....


It took me several tries to get the length just right. I also added a small piece of balsa filler to serve as a platform where the tank rests against a fuselage stringer. I secured the tank with two pieces of ΒΌ-inch-square balsa-one across the back and the other across the bottom. which sounds great but I'd like a picture...

I guess my main concern is...placement...

I read that a tank is better lower than the engine than above it....due to leaking fuel into the engine..is that correct???

also, does it have to be perfectly horizontal?
and does the little round part that sticks out...have to go on the top or bottom....

Ive built a few plans, just not in a long time....so Im a little rusty....

Please see attached for the specifics of my problem here [link=http://putfile.com/pic.php?pic=3/670340599.jpg&s=x10]GO HERE[/link]

thanks for any help....


Dave

Dave - I have a Seagull SpaceWalker II, and let me say that mine is very well built. It's my first taildragger, and it has taken a lot of abuse and just keeps bouncing back. As for the tank placement, my tank has flat sides and rounded top and bottom with a flat front and the opening located above the center line towards the top. When you install the tank, your going to be working with the bottom of the plane up, so install the tank with what I alluded to as "the top" towards the top of the plane and install the balsa brace below the bottom and that should get the tank in the proper position, or at least close. The fuel line opening should be in line with the needle on the carb, or at least in the close proximity. You are right, if the fuel line is higher, it will cause the engine to run rich and possibly flood out. As for the tank not being level, in the type of flying one will be doing with this plane, (it won't do any 3d, just simple rolls, loops, inverted, stalls, etc) if your off a eighth of an inch or so, it probably won't effect it very much, if the engine is located as it was set up (at the 7:00 position). I have not had any problem with mine at all. I run an Eveloution 46 in mine, and it is a gas hog. I wish I had a larger tank and had gone with a 51 to 53 engine on mine. It flys ok, but dosen't go vertical nor do the aerobatics nearly as crisp as my previous plane, a Seagull PC9. The SpaceWalker II is more like a "taildragger trainer," and flys very much like my trainer did. It's a nice flying airplane.

I hope this helps, as I have not had any problems with mine at all. The tank appears to be located properly on mine, and if the back of the tank is a little lower than the front, I don't think that will matter, in fact, when making an approach to land, that might be plus as the fuel will have a tendancy to flow towards the front away from the pickup due to gravity with the tank sitting level, causing a dead stick. I would not want it very much lower however.

I'm sure there are other opinions out there and mine may note be correct, but it is my experience with this plane and the set up. Yours may be different.

Dave, I did [link=http://www.rcuniverse.com/magazine/article_display.cfm?article_id=379]THIS REVIEW[/link] of the SpaceWalkerII

Put the supplied foam pad on top, put the tank's neck through the hole in the firewall and secure it like in the picture

MIke, I just realized something.
You said put the tanks neck through the hole in the firewall...MIne doest fit through the fire wall..the best I can position it is just behind it and slightly below it....

did they send me a different tank than yours or what...Ill take a few pics of my situation...for better understanding...



Thanks Again,
Dave

I have the same problem and question. What did we all decide? The tank neck does not fit through the firewall. Is that right? Is this OK? Thanks

[link=http://putfile.com/pic.php?pic=6/16711541375.jpg&s=f5]HERES A PIC[/link]

- it's on a slight angle
- I used 1/2 x 1/2 balsa ca for one piece and double stick tape on the piece that pushes it foward
- should be snug to top against foam and pushed forward - without kinking/piching the line of course

and yes...it doesnt fit through the firewall...

other mods I made...

Has anyone found a larger tank that fits in without modifying or cutting the plane?

Thanks.
