If I may ask you a couple of more questions concerning modifying guns in SP?: What units are you using for muzzle velocity? The default value is "800", but is that meters per second? I see you changed yours to "890". Also, how did you determine burstCount and timeBetweenBursts and why did you go for .7 on the spread? Thanks in advance!
Great build, very fun to fly...strafing ability against convoy vehicles is impressive and satisfying. I assume you reduced bullet spread? Anyway, great replica build!
Looks good so far...not really partial to the canopy outline thing unless there’s a functional cockpit underneath because it’s unnecessary unless there is. Is the tailwheel going to retract as it did in RL?
Interesting. Everyone builds the A-10 and no one remembers its competitor in the CAS competition. The A-9 was itself much more similar to the Su-25 in concept, which itself is a fairly useful and robust aircraft. I’m sure the A-9 would have done fine in its intended role, but the A-10 was the superior aircraft at the time.
@ArrowheadDesignCompany well, good luck. I graduated pilot training in 1994 and spent 24 years in the USAF. If you want to fly, it’s the service to be in, but you need to avoid RPAs if you can...though an RPA early on may still lead to a cockpit later on. I’ll consider a helo later on, but I take a really time so you might not see it for awhile.
@QingyuZhou Dutch roll is a characteristic of swept wing aircraft. When the aircraft path is disturbed along the longitudinal axis (side to side), the aircraft yaws, the leading side swept wing becomes “less swept” in the relative wind and produces more lift. This causes the aircraft to roll. An aircraft with dihedral wants to return to wings level (dynamically stable), so as the leading wing rises, it rises to the point that the vertical lift component becomes less than the opposite, low wing. The low wing then, in turn, produces more lift at that point and reverses the roll to the opposite direction. The cycle repeats itself until either the pilot counteracts it with the proper aileron and rudder input (the exact technique varies from aircraft to aircraft), or an automatic yaw damper mechanism intervenes (almost every large jet has a yaw damper) or the aircraft goes out of control or breaks up. What mystifies me is how this aircraft emulates this because there’s really no relative wind or swept wing effects present in SP. Try it: Fly your build above 35,000’ and start rolling...it will Dutch roll, pretty significantly, just like a real swept wing jet.
Pretty good for a brand new guy...the flaps are where the ailerons should be and the ailerons are where the flaps should be, which would help speed up the roll if they were swapped to where they should be 😃
@greasytortle you still kept the acceleration from being ludicrous, so...nice! I have to multiply engine power on my builds, usually at least 2x power, but still low-level speed tends to be low, while airspeed at higher altitudes tend to be high. Oh well, that’s the price of replica builds.
Nice, especially at only 253 parts...accelerates a little fast, but that’s a byproduct for f overcoming SP drag physics. Can tell lots of effort went down to this one
@F104Deathtrap true, you can't drop out of a nose door! Some planes, like the C-5 have both, adding to their flexibility when handling, or dropping, cargo. The Globemaster, shown above, C-124, I think it was designated, only had the nose doors, but could also drop troops out of the side doors, but certainly not larger items. You're probably correct in your thought it was probably designed that way for aerodynamic reasons, etc.
Very nice, you nailed the shape perfectly! Both the rotation/takeoff speed as well as the top speed want to make me yell “ludicrous speed!!!” I’d really like to see a 3.0 version of this as @EternalDarkness suggests, tame some of the negative flying qualities, also with red stars and without the 2000 lbs of ballast, she flies fine without it.
@Franticmatty saw your YouTube video where you flew my plane...very entertaining. In case you were still wondering, the trim slider on the right of the screen is the trim, which works the same way trim does on real aircraft. You slide it down to pull and keep the nose up, or push it forward to push the nose down. You mentioned "I have to keep pulling the nose up", well, that's what trim is supposed to do for you so that you don't have to keep pulling back on the stick, you set the trim and the plane should fly close to level flight. You seem to be interested in aviation. If you ever do graduate from simulations into real life flying, this is one of the first things your flight instructor will teach you about.
Very nice build, I like the subject, flies decently well, managed to take out part of the convoy before being blown out of the sky. One doesn't see too many WWI era aircraft on the site, even though there has been more of them as of late. To fix the (albeit slight) pitch down, recommend trying to stack a couple of rotators on top of each other, one set to pitch, the other to trim, that way you can build custom control surfaces which have both.
PAST is a good acronym to remember this...[Gyroscopic] Precession, Asymmetric Thrust [P-Factor], Spiraling Slipstream and Torque...only occurs in prop aircraft. Real aircraft experience this and it's most pronounced at high power settings and low airspeeds due to high thrust aggravating all of those PAST factors and a low airspeed making the flight controls less effective...at the worst possible time, low and slow. That's why pilots of powerful single-engine prop aircraft, such as most WWII fighters, add a bootful of rudder when applying power, especially on takeoff. When the aircraft are flying faster, the empennage and a little rudder trim take care of trimming out the aircraft to stay straight (@Tully201). Unfortunately, in SP, this is NOT what causes the rolling we've all experienced. It's caused by this; there are ways of fixing this, usually by replacing the offending parts on the aircraft and avoiding causing the problem in the first place (@AudioDud3).
Look here, used multiple parts for wings, plus built up the individual control surfaces as well and made them move with rotators. The Overload and Fine Tuner mods really help as well...I had to use Overload to get the sweep at the right angle ("offset"), so recommend you get those for your operating system.
@Bobplanes322 not really, they're quickly becoming the most widely known indigenous Chinese fighter. But I will agree they're a little less known than, say, an F-16, but that's not conceding too much. My point not, though, is that they're completely over built on this site. A couple of months ago there seemed to be a newly built J10 on the website every day...my suggestion, if you want unique, there are plenty of other jets out there...what about the Lansen or Viggen or Dassalt Mystere? Bet far fewer have heard about those jets...
I'll elaborate with my take on your question. Have you ever flown an airplane in SP and the nose constantly falls down or pitches up unless you hold the stick (pitch) forward or back? A little tiring, isn't it? Trim is a way to "set" a control surface, usually the horizontal stabilizer, to a specific position. This allows you to keep your nose "trimmed" up or nose "trimmed" down a certain amount to enable (usually) level flight, without having to keep the stick (pitch control) pushed up or down, especially when you change speeds while flying. As @SHCow answers below, trim is a selection in the submenu for control surfaces and is controlled by the up/down slider on the right side of the screen in iOS.
Some other things to know about trim: Trim is used in real life for not only pitch adjustment, but yaw (rudder) and roll (aileron) adjustments. In pilot training, the mantra is "trim's your friend" and learning to constantly use pitch trim is one of the very first skills taught to new pilots (believe me, new pilots never use trim enough). Trim adjustment is required whenever aircraft speed up or slow down, as in speeding up after takeoff to cruise speed and slowing down to land. That's why a trim problem in a large, heavy jet that flies fast (such as a 747) is a major emergency, while a trim "problem" in a Cessna 152 is usually no big deal and can be controlled simply by holding the yoke forward or back to compensate (a little pressure over a long period of time does wear out the pilot and make aircraft control suffer).
A link to the build would help illustrate the problem you're having, but, generally, when the CoM is too far ahead of the CoL, that will cause the nose to fall and the aircraft to nosedive.
Amazing, finest Spit on the site...nay, perhaps the finest fighter on the site! I’m amazed I did not see this when you first put it out!
+1Very cool, well thought out, excellent build; fun to fly and destroy things with!
+1An actual rotary engine, pretty amazing.
+1I like how you think: interesting subjects which fly nicely...keep it up!
+1Flies quite nicely, an interesting subject, nice build!
+1Very unstable, but a very pretty build and a nice effort on your part.

+1@Tang0five nice flying weather, finally, now that winter is gone
+1@Tang0five thanks! I appreciate the spotlight and the comment. How’s the U.K. doing right now?
+1@EternalDarkness I’m humbled by your assessment, thank you.
+1@Chancey21 thanks! I’m glad you like it. I think it’s my best work to date.
+1Extremely photo-realistic. And you even got the angle of the third engine correct. Flies very well, speeds are quite accurate.
+1This is really beautiful, makes me wish I was as good as you. Flies beautifully, it’s just a superb airliner.
+1Wow.
+1Nice build.
+1Again, nice. All the more impressive for having been created on iOS.
+1I like it!

+1Noice! Get them MiGs!
+1Deserves an upvote and spotlight if only for the epic number of parts!
+1Have you made a HAL Marut yet? I bet a good rendition of that airplane might get you some good points.
+1Meh, don’t worry about it...you have 47,000+ points, you’re a success in Simple Planes by any measure!
+1@Mustang51 sure, though I don’t anticipate it will be done anytime soon. I might be able to tag you an the build progress, though.
+1@DJ123 yes, I’ve done it, but it has to be a fairly large, slow-turning target...which is exactly what a Bear bomber would be, so it works.
+1I read Vulcan 607, great little war tale. And you should too.
+1Nice work. Very Soviet-y, looks like something the USSR would build because they wanted to be first, then use to haul cattle to the Far East!
