@Lotusrocks Like ADSFASDF1 said, it's the weight. Most of the plane's weight is on top, and slightly forward of center, so the plane wants to flip tail over nose.
What you need to do is shift the center of mass lower so that it wants to stay right side up, and either further back (which will probably require moving the wings back) or bring the floats forward to counteract the tendency to pitch forward.
I posted one way to deal with it (under successor aircraft), but there are lots of other ways to accomplish the same thing.
@LiamW I figured it wasn't simple. As for "easily" getting the right shape, well not necessarily for me, at least not yet. I tend to work on smaller designs and often run into situations where I can't quite get the shape I want out of it. Scaling helps somewhat, but it also brings new problems.
But it was just a thought. There are quite a few good 3D plane models out there.
@BoomarooFlyer Use the "Share Aircraft" button in the game (it's right above Mirror Aircraft), but you should really ask something like that in the forums.
Depending on just how complicated your cockpit design is, you might be able to do simply by overlapping some fuselage cones. Pick one cone for the nosecone, and possibly give it a bit of a drop at the tip, then use a smaller, squashed cone for the windows, and color them in a glossy black or blue.
Add a gyroscope, then you should be able to take off and land like a helicopter. You should probably raise the wings to keep the props and jets from touching the ground, too.
@Gvb2003 Thanks. I'm working on it. I'm surprised at how well it's working out so far. I kinda eyeballed it for wing shape and such and it actually worked. I'll need to adjust dimensions, mass and drag a bit more to fit with official specs, but at least it flies.
I replaced the nosecone with a fuselage inlet and got rid of the the slim inlets. What happens is that even though, on paper, the fuselage inlet produces more drag than a nosecone, it sucks in the air that would be producing drag, and ends up being faster.
BTW, It's a really decent design, since it handles 1600 mph well. It doesn't shake, wobble or become erratic or anything like that, it just flies. Good design job.
If you want upvotes then you have to post aircraft that appeal to people in someway. Most of the experienced people here, the ones with thousands and thousands of upvotes, tend to make very advanced and aesthetically pleasing designs, and they probably won't be all that interested in basic designs unless they have some sort of novelty to them.
I don't quite have as many upvotes as you and I got most of mine from a handful of Ornithopter designs, that caught some people's interest, and even then most of my upvotes were from a handful of people who were also interested in ornithopers.
Just build aircraft, post the ones that you like, and let the upvotes fall where they may. You can even enter some of the contests, but do so for the fun of challenge and the learning experience of building a plane under constraints, don't do it (or anything else here) just for the upvotes. It's not like they are worth anything.
I tried to fix it just enough so that it can fly, the link is under successors.
BTW, just what are you trying to do with this thing? Five x1000 BFE 500 engines is more thrust than this, or just about any other vehicle can handle.
@Hyattorama Yeah, I doubt it's possible. SP is a simulation, and it doesn't mirror reality exactly. So even if someone did an exactly replica, it wouldn't perform exactly the same due to those differences.
@Hyattorama More like 5 times as heavy. The real thing was around 1300 pounds when loaded. But lightweight planes are a pain in SP. You have to XML edit things and then deal with the fallout. Case in point, in order to get the thing to run for 1hr 45min on 20 gal of fuel, I had to lower the fuel input to around 3.5% of norm, and multiply the power by a factor of 28 to keep the 110 hp output. So now SP thinks my Bristol got a 3000 hp engine, even though it can only make 115 mph.
As for your 130 mph, I've seen 132 listed in some places, but that was for the C model with the 130 hp engine.
@Hyattorama
I haven't posted my version. Mine is mostly scaled, and flies, but needs some work to fix trim and adjust match up properly on performance. If I know how to post it "unlisted" I'd let you take a look at it for a laugh. I think my Vickers machine gun looks decent, but the rest is rather crude.
Yours looks so much better.
What I was thinking about your was to see if it could be scaled down in weight and power to match up with actual specs. I have a machine gun and some UK emblems you could have for cheap, too!
Yes it is rudimentary, except for the twin props, but it works. There really isn't a need to make it more complex, and it is fun to fly. Now if you wanted to do something more with it, Idunno make it a seaplane, or STOL or something, then you'd have a reason to make it more complex, but even then, I'd rather start with a good basic design and add to it, as that way I know what the effects of any alterations are.
BTW, I was doing some research for a plane and stumbled upon your Bristol M1. Are you still working on that? It looks pretty good, much better than my M1.
While, as already mentioned, structural wings are the way to go, if you don't want to or can't XML edit things, you can reduce wing wobble by just using normal wings at the points where you want control surfaces, and structural wings for the rest, combined with nudging the wing a big into the fuselage for a bit of extra support.
Just how much this will help depends on you design and just how much it pushes the envelope.
If you don't or can't XML Mod it, what you can do is build your wings in two sections. Use a structural wing for the part that connects to the fuselage, and a standard wing for the part with control surfaces.
You can also use the position tool to nudge the wings into a fuselage a little. That seems to help reduce wing flexing.
@Minecraftpoweer Yup. But I'm thinking more about scaling down a SP build to match up better with a real airplane.
For example, let's say I'm building a replica of an old WWI biplane, and, once I work out the shape and parts, it weights 3000 pounds in SP, but the actual airplane weighed 1500 pounds, so I scale down the mass to 0.5 on everything to get the weight down to 1500.
Now if I wanted to reflect the lightweight, and less durable materials used on old biplanes I might scale down the Health from 100 to 50. I just wanted to make sure that I wasn't double dipping.
Oh, BTW can one 2 unit long section take the same damage as one 4 unit long section, or half?
The problem is with the inner back section of the wing fuselage (the one that holds 241 gal. of fuel). They are slightly off (less that 1/1000th of a point) in the X coordinates from each other, and that's what causes the bank. I tried to correct it in
Overlord. but SP seems to it adjusts it back in play. I think I was able to fix it manually though.

What else needs to be done?
@Milo1628xa I thought it looked a lot like a minisub, with that great forward view and fin-like forward wings.
Simply Gorgeous design.
+2I had a similar problem, but it told me to disable all mods, and then it worked. Try disabling mods.

@LiamW Aren't you always working on designing a plane?
@LiamW I figured it wasn't simple. As for "easily" getting the right shape, well not necessarily for me, at least not yet. I tend to work on smaller designs and often run into situations where I can't quite get the shape I want out of it. Scaling helps somewhat, but it also brings new problems.
But it was just a thought. There are quite a few good 3D plane models out there.
@BaconEggs LoL! Considering that SP has nothing to reflect stealth, that's pretty much the truth.
+1@LiamW I was thinking that even if the object was turned into bunches of fuselage blocks it would still be a way to get the right shape into the game.
@InternationalAircraftCompany It should work except there is no way to import the files. In theory it should be a two way process.
This is a really clever way to do a powerless engine.
@BoomarooFlyer Use the "Share Aircraft" button in the game (it's right above Mirror Aircraft), but you should really ask something like that in the forums.
+1Nice.

+1@stig27 No, I just typed it. I could build it. Hmm, maybe a triplane would be better?
@Gvb2003 Thanks. I'm working on it. I'm surprised at how well it's working out so far. I kinda eyeballed it for wing shape and such and it actually worked. I'll need to adjust dimensions, mass and drag a bit more to fit with official specs, but at least it flies.
@AWESOMENESS360 Stack two layers. Lol!
Shouldn't this be a biplane? ;)
Glad to help. Your first small jet is a lot better than my first small jet was (R.I.P.).
@F104Deathtrap Don't forget the mass production factor. Smaller aircraft need less materials to build, so you can make more of them.
+3I replaced the nosecone with a fuselage inlet and got rid of the the slim inlets. What happens is that even though, on paper, the fuselage inlet produces more drag than a nosecone, it sucks in the air that would be producing drag, and ends up being faster.

+1Kinda neat
@randomusername A 1 pound spaceship with 1000 pounds of thrust should be able to accelerate at 1000G's, which is over 21,000 mph per second.

+1This is a pretty good basic jet, and a lot faster than 800 mph. I got it up to 1080 mph at 65000 feet. With jet a minor tweak this could break Mach 2.
+1@DustyT33- I think the key to faster water speeds might be to put a flapper at the BOW of the craft. Putting one aft makes it go in reverse.
Oh, and horizontal flappers work just fine underwater. Most of our earlier designs function underwater.
While, as already mentioned, structural wings are the way to go, if you don't want to or can't XML edit things, you can reduce wing wobble by just using normal wings at the points where you want control surfaces, and structural wings for the rest, combined with nudging the wing a big into the fuselage for a bit of extra support.

@Gvb2003 You're welcome.
@jamesPLANESii Thanks. I only installed Overlord last week, so I had to find some solutions to problems that didn't involve editing the XML data.
Nice place you got there Grandma. With all the Ack-Ack, watch towers and and the Zero you uploaded earlier I take it this isn't a Club Med resort?
If you don't or can't XML Mod it, what you can do is build your wings in two sections. Use a structural wing for the part that connects to the fuselage, and a standard wing for the part with control surfaces.
You can also use the position tool to nudge the wings into a fuselage a little. That seems to help reduce wing flexing.
+2Do you still need help?
Nice looking plane.
+2BTW, If you use the water pedals, you can take off without using the flaps. Great water pedals.
@jamesPLANESii Congrats! I bet if you contacted them, they'd let you use those logos, too.
MB 152?

This is great!
So you need a mile clearance on either side to land it! Lol!
This is a very nice bomber. It can reach speeds of Mach 2, and uses a VTOL engine and thrusters that help with maneuvering.
