Rune Posted January 7, 2015 Share Posted January 7, 2015 Ok I need some help on this. http://i.imgur.com/fpY5Yii.jpghttp://i.imgur.com/HYP8JJs.jpgOnce the plane's pitch goes below the prograde marker, it will immediately pitch down uncontrollably. No flips or spins, just a lawn-dart. Meanwhile, keeping it pitched up will allow it to fly perfectly, no issues there. I've tried putting canards on the front, in the back, etc. but it refuses to even change it's flight characteristics. Putting that lift indicator in the front or back or on top (as in the pics) of the CoM also has no effect.It's not an aerodynamic issue. Basically your thrust is over your CoM and that is creating a downward pitching torque. Move the jets down or the CoM up, and the issue should solve itself. Although a CoL before the CoM is another recipe for disaster, especially with full tanks on the rear of the plane.Rune. It's often overlooked.

It's often overlooked.Not entirely sure about this... It did make it easier to take off, however now it seems to be worse. After putting the CoM and CoT as inline as they could be the plane now pitches up when above the prograde and pitches down when below prograde. The thing cant stay on the prograde marker.

Balance problem should be obvious then.Yep, flys 100% straight. Besides, any thrust issue would mean pitching in one direction, not both up and down.

inigma Posted January 7, 2015 Share Posted January 7, 2015 Yep, flys 100% straight. Besides, any thrust issue would mean pitching in one direction, not both up and down.Then the prob is either wings or misaligned torque. Quote Link to comment Share on other sites More sharing options...

You have an inherently unstable plane right there. CoL should be behind CoM at all times, so check what emptying the fuel tanks does to its position. More than one SSTO found that out the hard way when coming back to land...Rune. So in other words: the pics you showed were wrong in every possible way. Sorry!

GusTurbo Posted January 7, 2015 Author Share Posted January 7, 2015 (edited) Preparing to release this:At 479 parts, it's my lowest part-count Saturn V yet. I still haven't touched the LEM, which should yield even more part savings. My apologies to Kurotenshi for the timing. I've had this on the back burner since .25, and .90 has allowed me to make some incredible improvements to the design with the new gizmos.

GusTurbo Posted January 8, 2015 Author Share Posted January 8, 2015 Thanks. I'm shooting for a balance between playability and detail. After a total redesign of my LEM, the whole system has 424 parts, which includes 4 launch clamps. I've completed the visuals, now I'm going for functionality.Old LEM for comparison: Quote Link to comment Share on other sites More sharing options...
Kurotenshi Posted January 8, 2015 Share Posted January 8, 2015 My apologies to Kurotenshi for the timingThat's ok, let's just say great minds think alike or something like that You're ahead of me though, as you already have the LEM. But then again, mine comes with a Saturn IB and Skylab, both of which are finished. Just down to the LEM and refining the Saturn V now.Also, awesome job on the interstages, especially the spacecraft adapter (the top one). Small question though, what's the use of the double decoupler between the SII and SIV-B? If it's for a two step stage separation, that's unneccesary. The SIV-B interstage stated attached to the SII, even though it was constructed as part of the SIV-B Quote Link to comment Share on other sites More sharing options...
GusTurbo Posted January 8, 2015 Author Share Posted January 8, 2015 (edited) Thanks! The big 3.75m decouplers are only there for added length. They're placed at the top of the stage list so they don't get triggered by accident.I think your version is more accurately scaled for diameter in the S-I and S-II stages. I made it narrower to get the stripes to look how I wanted. Edited January 8, 2015 by GusTurbo Quote Link to comment Share on other sites More sharing options...

Guest Posted January 8, 2015 Share Posted January 8, 2015 (edited) Here's the front fork teaser (warning part abuse not for feint hearted ^^): I went this way because it's low on part and effective, but before that I also tried something with 2 symmetrical tubes like the real thing, KSP kept crashing for some reason and it wasn't neutral (it created some asymmetrical ghost forces) ...But hell it looked cool!

It sure did. I see a problem though. This is for the front suspension right? I foresee that it will move minutely, if at all when used on the craft. I see it takes a lot of thrust to move a little. There wont be enough weight on the bike for it to move. Quote Link to comment Share on other sites More sharing options...
Guest Posted January 8, 2015 Share Posted January 8, 2015 (edited) Hey MJ,I clipped 8 medium battery in the command pod with radial symmetry to add weight on the main body, but it really all depends on the speed you're at and if you go on jumps etc, the main purpose of the 2 wheeler is also to have this inherent instability that put the frame at works all the time, so even if suspension travel doesn't move very much it improves handling greatly.Here's the early craft (87 parts) with the mod I recommend to use with included (Hullcam for parts that give 1st person view, and ImprovedChaseCam for chase view moving with speed vector).It feels like being on a cloud above the road =)at high speed too (up to the rover wheel speed tolerance), but it's not perfect, too early for that and not really the point anyway lol.It needs infinite fuel cheat btw (i'll fix that).https://www./?59pluoxhqumq0oo1 Toggle Engine / 2 Rear Brake / 3 Front BrakeIt's set up for joypad, so if you want use a keyboard, which is fine too, you need to click uninvert steering on all 3 front wheel to turn properly.

soulreaver1981 Posted January 8, 2015 Share Posted January 8, 2015 hey guys here is a little something i'm working on.a copit with stock moving canopywhat do you guys think should i release it like this or should i build a plane around it?

problemecium Posted January 8, 2015 Share Posted January 8, 2015 You should make the whole plane look like it's flying backwards, too, just to enhance the silliness So I'm just about wrapping up my new Station in a Tewb for 0.90:The whole thing is supposed to be able to fit within a 2-meter fairing and then "unpack" in orbit.

Majorjim! Posted January 9, 2015 Share Posted January 9, 2015 (edited) Hi all, I've been trying to come up with a small stock bearing for a while and I have finally managed to stabilize it.In the video you can see it set up as a turret demonstrator. Sorry to be a tease but the method is a secret at the moment unit I finish a craft using it. I will say, I haven't seen any other bearings that are built like this.It is really stable and can, as a turret pivot up and down for aiming. Have a look at the video below. I will add that the ailerons are there simply to cover the mechanism. Its a bit smaller underneath.

Plot twist: The ailerons make a great bearing, you just need to make the ring a bit smaller.Ok, I haven't actually tried it, but you still gave me the idea.
