Confused with the new aerodynamics model...

[Candlelight]

I have never used FAR, but i have used NEAR once.

The thing is that i got used to the old stock aerodynamic model, now it's really hard for me to launch anything with this new FAR-like model.

Can anyone give me some help, please?

EDIT: Just wanted to say that using MechJeb makes it worse, my rockets flip out of control.

Turn about 5 degrees immediately at launch and then follow the prograde marker. You should end up turning very gradually aiming to be at about 45 degrees at about 10km up and around 25-30 degrees at 25km up. Above this point the air rapidly thins out and by about 35km has almost no affect on your craft, you'll probably be at about 10 degrees by this point. From there it's pretty easy.

Gravity turns with low torque and/or TWR is a bad idea.

Decoupling anything just got 10x harder.

Heating, then exploding.

Fairings are now useful.

Jet engines are your best friend.

Nuclears.

More nuclears.

Nuclears in atmosphere are actually not great, nor good... or even decent.

Nosecones matter.

And last, winglet exploits.

Thx.Now i can get ALL the probes into orbit.

I did a switchover to FAR a couple of months ago; the new aero is a lot like FAR, as you've already observed. You might be able to learn out of my own shenanigans.

For rockets - aim for a 1.2 stage TWR, and plan for about 3500 m/s of delta-V. In my experience, this usually translates to "build a rocket like you did before, but add nosecones and fins". The extra mass of the aero stuff will bring a 4500 delta-V rocket down to 3500 pretty efficiently.

For planes - not all of the mods I use have been updated yet...

Planes are simple, just keep your CoL just behind your CoM and dont get crazy with your design. The simple rule of thumb is "if it looks right it will fly right." Is very true in the new stock model.

Well, to be fair towards the LV-N, its ISP is low, but at ~1500m it already becomes on par with the other engines.

Still, low TWR.

I haven't seen this mentioned yet, but you really want to be concentrating on serial staging versus onion and asparagus.

Plus it's a good idea to make your first stage last until you're in the upper atmosphere, if possible. It's not always possible, especially if you're playing career and you haven't gotten very far into the tech tree. Boosters should only be used to get you off the launchpad and moving in the right direction.

Last but not least, when building rockets, design darts. Top heavy is good. You really want your CoM well in front of your CoL. This actually makes your rocket more stable.
