You are most welcome.

Damm you even reply to comment to an old video? You are a great KZbinr!

@@lolermosskoss1834 Thanks

Some of the advantages only apply to real life as KSP doesn't consider fluid dynamics in its physics model. But as far as Newtonian physics it does. This opposite rotation of the propellers cancels the torque and makes the plan very stable and easy to fly. I don't remember what all sources I used as I did a lot of research about prop planes and helicopters. I know I also asked a lot of questions to my friends that are actual pilots.

Thanks for your answer. I would also like to ask you whether there is any additional vibration problem with the rear engine in the push-pull configuration. If so, is there any literature on how to solve this problem? And whether the efficiency of the rear propeller is disturbed by the airflow through the front propeller, causing it to decrease? Finally, are there any design solutions or design difficulties related to the intake and exhaust of the push-pull engine?

@@billcroft449 I know I read up on a lot of this before making the video. Unfortunately, I'm not recalling all of it. I believe there were some slight issues with efficiency with the rear props due to the airflow around the fuselage - maybe it was about 80%. I don't recall reading about any issues with the intake or exhaust. Some advantages I remember were that it didn't have the noise issue that a typical contra-rotating prop design has, but it still cancels out the torque. And there isn't an off center thrust issue due to the loss of an engine. Rear mounted props were a liability early on in aviation as it was very dangerous for a pilot trying to bail out. But with an ejection seat, this wouldn't be a problem.

@@Echo3 Thank you for your explanation

You can also place an engine like the RAPIER on the rover with the exhaust side pointed up. The center of mass of that engine is further forward than the piece itself. So, you can make a rover with the center of mass below the ground. This is very stable.

That doesn't sound like a issue of too much lift, but either an issue with the center of thrust or the placement of the wings.

This is a mod called Rocket Sound Enhancement. It adds effects to the rotors and servos too.

@@Echo3 Thank you!!!

As far as I know, it works similar to a real one. I did research on how they were set up. For more realism (and this would more like how they are really designed), you can add some hinges between the unpowered rotor and the blades to let them flap a little bit and swing fore/aft a little. The game doesn't have a full aerodynamic modeling, but with FAR and the ground effect mod, it would be pretty close

Thank you. Have you ever tried to make an autogiro in the game before?

I think it's either Phoenix Industries EVA Survival Suit or Benjee10 Suits

Alright, thanks!

Thank you.

The Wright brothers did go on to sell some of their early planes to the military.

@@Echo3 interesting.

This is before I was recording in 4k. So, you are making a counter-rotating mini helicopter. The basics are to make the rotors as small as possible, use the duct fan blades, use a KAL-1000 to adjust the blade deployment angle. Bind the blade deployment angle to the KAL and bind the KAL to the main throttle. Set the deployment angle in the KAL to go from 0 to about 8 or 9.

@@Echo3 figured out the issue, my goober ahh self didn't deploy both sets of blades, it works now lol, also I was able to switch from phone to pc to watch this in a higher quality lol, sorry for taking up ur time

@@qie2iqee No problem. Glad you got it working.

Yes, but I found this method to be easy to control.

Thanks

How hard are you landing on the front gear? If you share some video (I'm on the KSP forum and reddit with the same name) I could take a look at your craft. You could also share it on KerbalX, and I could try it if you send me a link.

@@Echo3 Yea, I can get my craft file sent over to you later on. It uses mods but Kerbal x should tell you what mods it uses

​@@bfgedits2024this should work. If I make any changes, I'll share it with you on KerbalX.

That's Kerbal Konstructs

The ground anchor can be buggy. It is probably better to use a mod that has the ground tether instead.

Nice

Haha

It is called Minmus

@@Echo3 For some reason I thought you called it Minimus.

@@mapolinski It is possible that I misspoke

I agree. Using the KAL to control the deployment angle is my preference, this is to be a quick and easy tutorial. No need for that fancy KAL-1000.

Thanks for subscribing. I try to be open about what works and what didn't.

Are you using one or two rotors? If you are only using one, then the torque from the single rotor will cause the craft bank. This is one of my earliest tutorials, so I don't think I explained things overly well. I like to bind an action group to rotor torque. This should get them started and help you control your throttle. Don't hesitate to ask questions, I'll do my best to answer them. I'll also active on Reddit and the KSP forum with the same user name.

@@Echo3 I forgot to add that I also used electric rotors and not those other rotors that use liquid fuel (not that I think it will make a difference).

@@AnonymousUserInUse electric won't affect how they operate, just what resource they need to run. If you are able to show me pictures of your designs, I could probably give you pointers more easily.

Every subsequent video in the series has the full mod list in the video description.

@@Echo3 thanks

BDArmory adds the enemy AI

@@Echo3 ooh very cool I might have to check it out then

@Echo3 I got bd armory and I don't see how to unlock weapons or missions with ai in the career mode any ideas?

@@skurtkobain6117 Oh, in career mode, I got a mod called Contract Pack: Defense Combat Advisors.

I did a few older mods manually, yes

The mod conformal decals.

@@Echo3 ty <3<3<3<3<3<3<3<3<3

@@mertarican5456 No problem

0:17 is not a custom config, it is from the mod Kerbin Side Remastered Gap Extras 2:54 is the dry center of mass indicator from the mod RCS Build Aid. A great mod by the way that makes placing RCS ports and building planes a lot easier.

@@Echo3 Thankyou :)

haha

With my design, I dropped the propeller stage when the atmosphere thinned to the same as Kerbin Sea Level. So, you may find that Kerbin is not ideal for conducting tests. You can assign yaw pitch and roll control authority to the propellers to help with control. =

@@Echo3 Thanks, I didn't realize authority was off by default on the propellers, they must have changed it since you made this video. It's working well even on kerbin now

That is awesome!

I've started recording it but have been very busy with things irl.

Thanks
