Status: offline 		Guys, Just received My Seagull 90 Ulti. Fine looking bird. The one thing I see as a problem is the firewall. It looks like soft-ply and pushing on it causes it to flex. I have read all the forums concerning this Ulti and no one has addressed this problem. Has it even been a problem? It just seems weak to Me.
I have read that a Carl Goldberg can take a 180 Saito. It weights just 2 oz more than an OS 120 Surpass E. The planes are very close in size (and hopefully ,construction). As I had planned on utilizing the 180, what would be a good plan of attack to strengthen this lil bird up?
From what I've read , Daveopam had one with a Saito 125 and was not really pleased with its performance. I know it is not a 3D monster, and at the weight it is a big engine will likely make it a flying brick, but that's ok. I want it to hover at 1/3/ to 1/2 throttle and pull-out like a rocket ,straight up into oblivion... Thanks.. TJ. oh yeah exactly 5 years ago to day I was on the forum trying to find what engine was right for this bird (http://www.rcuniverse.com/forum/m_4713909/mpage_8/key_/tm.htm)....now I have the bird .. Good things come to those that wait??????

I have only seen this plane one time at the flying field where I fly, but here are a couple of suggestions I would reommend you do.

- Epoxy some triangle stock behind the firewall if there is none there.
- If the edges of the firewall are not exposed, you can pin the firewall to the sides of the motor box with epoxy and wood dowels.
- If you are serious about using the big Saito, I would recommend adding flying wires on the tail feathers if they are not already included.
- Some of the Seagull models I have seen are weak around the landing gear block, so I would beef up the area around the blocks.
- If the firewall looks too soft, you can remove any existing triangle blocks with a heat gun and add another layer of plywood and epoxy it behind the existing firewall. Then pin the new firewall in and epoxy in new triangle stock.

If you do all of this, I don't think you will have any issues with added weight, especially with the Saito 180 bolted to the firewall. BTW, the one I saw had a YS120 bolted to the firewall. Good luck with your Ultimate................

David

Status: offline 		I've build a few Seagull airplanes. You definetly need to beef up the firewall. I put 2 oz glass around the outside and added triangle stock inside where I could fit it on the Cap 232
I just build. If you don't I've found that the firewall has come loose on all the ones I've built. I'm sure you will love the way it flys. My Seagull airplanes always seem to be the favorite in my hanger. Also if you can get some epoxy around the landing gear area it will help also.

Status: offline 		hrrcflyer, sounds like some good tips. I was a bit worried as the sidewall flexes. I didn't know You could use a heat gun to loosen the tri-stock glue.. kool. Was afraid I'd be forced to slice it out with a razor knife and I heard the lg block was weak, so I was planning on strengthening it up but it looks almost impossible to get to.. Gonna be fun, Me thinks.

Status: offline 		zacharyR , lol.. yeah, I get it. But that's the American Spirit. It was never designed as a lightweight 3D machine. I knew it was a sport flyer from the start. But I have a 180 Saito and as I always say, "If a lil bit is good, a whole bunch is better and to much still ain't enough". TJ

Can't help but wonder if ole Zach here EVER has anything positive to say about ANY other ship OTHER than the one he owns?

I have a SeaGull Ultimate 90. I have had it with a 1.20AX, a YS 1.10FZ and currently a DLE-20. Mucho fun on the DLE. 3D machine? No, but a smokin sport flyer (despite Zach's opinion) that flys IMAC stuff with ease, tracks straight & turn, holds upline and downlines, inverted or upright like a much larger ship. And she lands like a puppy dog. 

How can anyone complain about a good looking Ultimate BiPe that flies well, comes with decent hardware and gets delivered to your door for $199.99? I know Zach, it's not an ultra light super expensive Aeroworks or Pilot piece, but it's decent ship at a low price and as long as you are up to the task, the Ultimate can handle what you throw at it with ease.

Status: offline 		Giant_Scale_Gasser , just no pleasin' some folks. lol. You are right in that for the price, it looks like a great value as well as kool looking. I'm not really wild about the color scheme, but it ain't real hateful, Ya know?
By the way Gasser, did You ever have trouble with the firewall flexing? It just seems a little on the light side.I went through it and the hardware isn't all that bad.I will probably upgrade some of it once it is air worthy. There are some things I was a bit worried about..like the firewall and landing gear block, but all in all I like it.
And as far as over powering it, In the Parkzone "Gunfighter" forum, I got over 900 watts with a 4s1p 2200 40c battery, 3542-1250 kv motor and APC 8x8 prop. It flew most awesomely....I built 2 more for guys in the club. I am old skool on power. It was the great American spirit that made my grand-pappy put a V-8 Lincoln engine in a '40 Merc and a Caddy big block into a '34 Ford Coupe. Best Regards, TJ

Personally, I have had no firewall issues with it. In fact I have had no issues with the airplane at all. As far as the landing gear block goes, I have several airplanes that I read about needing to support or reinforce the landing gear blocks, of which I have done none of them. I prefer to learn to land each ship better to be honest. I am a stickler about greasing my ships in. The Ultimate is a big baby on landing and you can set her her down just about as gentle as any trainer with a little practice.

I love my Ultimate. I have her for sale currently because I am mout of room in my shop, but I think I have that resolved and will not need to sell anymore planes.

Status: offline 		I've had mine for about 3 years with no major problems. This winter though I was doing my usual look over of the plane looking for anything fishy and I did notice a little flex when I wiggled the nose cone. I haven't taken the cowl off to investigate further, so I'm not sure if it's just my imagination, the motor mount, or the firewall. Either way I'll probably do a little beefing up while I have the cowl off.
Another thing to watch for is the cabanes coming lose. The bolts that held mine to the fuse liked to vibrate loose. A little loctite fixed that.

This a one of my favorite planes.

Status: offline 		Giant_Scale_Gasser, how did Your CG work out with a heavy engine up front. It was "designed" around the Saito 125. My Saito 180 is 10oz. heavier. Don't want to add weight at the tail so I'm dry fitting everything then will balance it from there. May have to move the servos... Sure hope not. How did You do Yours? TJ

If I remember correctly, it balanced on the recommended CG with a receiver battery up front just behind the firewall.
Flied great!
