Too fast landings

[Hodo]

Stock no moded parts, just FAR. Now I'm trying to use canards, but when it reaches high AoA it starts to roll, it's really easy to recover, but makes it hard to fly.

I understand just stock parts, but I was just showing you the CoL and CoM relation. As long as they are REAL close you can get a really maneuverable craft.

Like this craft, it was from a few versions ago but it wasn't that maneuverable at speed because of its large distance from the CoM with its CoL. It handled about like a truck.

But this one was quite agile for what it was.

Notice the CoM and the CoL relations.

So des anybody knows how to stop that rolling sensation on high AoAs?

This is kind of a shot in the dark, but wth.

I'm not sure exactly how FAR models the airflow, but I'm guessing at a high angle of attack, the rudders are blocked from airflow and the high angle of attack disrupts airflow over the wings, meaning their control surfaces aren't effective. I'm also assuming that

So here's rub: I think it's really hard, if not impossible, to prevent this. The best solution is to avoid the high angle of attack (Kind of curious what you're qualifying as "High angle of attack").

You may be able to place rudders & control surfaces on the ventral wing surfaces to prevent the roll using aerodynamic control. Another solution may be to use RCS and SAS to arrest the roll.

And, as always, if you're not providing pics of the craft, there's very little the community can do to help you. Also, more information about the conditions under which you're having issues (e.g. high altitude) would help.

Do you mean that nose up and down oscillation that happens? If so that is from over control generated from the SAS module. FAR does not play well with it lately, Regex had a plugin called the PID which let you set the control authority in it to about half or one third of stock and it eliminates that issue. The other way to help lessen this problem is to set your control surfaces to a much lower sweep angle. I think they are default 20deg, you should set them to about 3-5 and that will help with the problem.

It only happens when I add canrds to the front of my jet. I want it to be near supermaneuverable like most of modern Sukhoi aircrafts.

It is because of over-control. Try reducing the max pitch angle of the canards.

I've just realised, that my FP-17 was pretty carppy compared to my new ones...

[slumpie]

I just tested your FP-17 and to be honest, it's crap. Pitch control is almost non-existent...

I'm sorry, but it's true. Not the speed or lift is the problem, it's the controls.

Using FAR?

EDIT: You know what? It is really a crap.

Edit: Remember, a deployed parachute will cut automatically during descent if propulsion is used to increase vertical speed past zero.

Heh, I ran into this on one of my very early flights. I was trying to use the last of my fuel to slow down enough to keep my engine from exploding on landing (I didn't have landing gear yet). So I'm coming down, chutes come out, I'm tapping the throttle, I can see my shadow. I throttle a bit to try to get just below zero. Oops...too much throttle, now I'm going up a bit. Wait...what happened to my chute? Then my fuel cut out and I slammed into the turf and the only thing to survive was my capsule.

Two things:

1. Angle of attack has greater impact on speed than anything else: simply turn the engines down/off and slowly pull up your angle of attack until you are going slowly on your glide slope. Just be careful not to stall.

2. Use pairs of wheels for your rear gear: If you place 2 wheels next to each other, where you would normally place each rear landing gear, they can take a lot more abuse.

3. Use flaps. This is self explanatory. If you want a plane that normally can't fly slow to fly slow for landing, add flap functionality!

4. Learn to flair: Flaring to the point of a partial stall right before touchdown can really slow you down.

5. If this isn't obvious, you can always use parachutes to assist in landing. Deploy them right before touchdown and you can make your landings much faster without wrecking, or make your plane land with parachutes. It's your choice. Don't say it's cheating to make planes land with parachutes, NASA and the Military do that all the time. Most drones land using parachutes, because it's simply easier. The only reason most radio control planes use runway landings is because it's more fun.
