Getting the 3-views should be the very first step. Trying to re-engineer a build after the fact is sometimes more difficult than a whole new build. Hope the 3 views help. If you need a tester, have a question or need some help, please let me know.

@ChiChiWerx I was planning on doing that next, as a mater of fact, i was looking at the blueprints.

@AikoFoxNeko good. Now, you should work on flight characteristics. In order to attain realism in your replicas, you need to make them reasonably easier to takeoff and land, plus turn realistically. There are ways of doing all those things in SP. Since you’re trying to build a Blackbird (by no means an easy build), download this 3-view of the jet. It has a scale next to it which is vitally important in getting proportions correct—in SP, 2 units equal 1 meter. Don’t get caught up in details, just get the proportions of the major parts, fuselage, wings, tail, landing gear placement correct. The Blueprints sure is great for 3-views, almost everything is on there.

@ChiChiWerx The engines and wing were amazing, i actually got the plane to Exceed 3000 Mph

Here’s the same pack, someone added a structural wing. Good luck

Here is a useful engine pack I’ve used in the past.

@AikoFoxNeko and you have not yet discovered that you can search “parts” in SP. Both structural wings with control surfaces and more powerful engines are freely available for you to use. Go to highest rated builds of all time, find a parts pack (many towards the top of the list), click on the “Parts” tag. That’s what I did when I built this on iOS.

@ChiChiWerx You seem to have forgotten that ios users can’t use XML

@AikoFoxNeko there’s no difference between planes flying 800 mph or 2000 mph in SP. Besides, in RL, the different airspeed regimes are around .8 M to M 1.0 (transonic), then faster than Mach 1.0 (supersonic), and faster than around Mach 4 (hypersonic), all of which actually don’t correlate at all in SP. There are no Mach effects, no rapid increase in drag in transonic flight, no Mach tuck and no shockwave. Going faster simply increases drag on an exponential curve and requires an exponential power increase. If you can build an 800 mph airplane in SP, you can build a 2,000 mph in SP. The difficult part is building an airplane that can take off well (i.e., rotates at/around 200 mph or less, accelerates realistically, is controllable on takeoff...no wild swerving) and land well (controllable in pitch, roll and yaw at approach speeds—around 200 mph or less, has enough nose up trim to fly hands off, enough pitch authority to flare and not bang the nosegear or explode on touchdown and is controllable on touchdown). THAT’S the challenge in SP. Flying faster than 800 mph in SP is not a challenge. All you need is to XML edit structural wings and engine power. Anyone can do that, no problem.

@ChiChiWerx Actually, i have been playing for quite a while, im just used to building small, slower planes with speeds up to 800 mph. This project is pretty difficult, but i worked the problem out. I had to use structural wings on structural wings for details, and put primary wings inside to pull up or down. It is kind of hard since this plane is going in excess of 2000 mph.

@randomusername some points are valid, but many simply aren’t true or understandable without building experience. This guy has 119 points, perhaps the basics or more explanation would be more useful. Better yet, how about he links you to his build and you can try and analyze what’s wring with the build. He’ll learn better that way.

@randomusername I see, i have all of those things now. Just a few differences.
