So here are 2 designs for my satcomm rockets...they both crash and burn. Can I leave the box out and still have the ascent control window or do I need it.

You need the box :)

on your second rocket have you tried removing all but the bottom 4 winglets?

Yes, still crashes.

My only option at this time is to strap 4 heavy rockets to it and try to go straight...it did once, but then I had 4 heavy rockets orbiting the satellite.

Wait a sec... are you trying to burn straight to 3000km ??? Try setting it to 100 km first then moving your AP to your final destination once in orbit.

No, I have the ascent guidance window up and it's supposed to make the orbital node. I want to reach KEO.

That's likely your problem: DRE.

Problem? Oh I know it's likely to explode hence my desire for an inline module for mechjeb. My next desire is an aerodynamic landing strut etc for similar reasons.

I managed to get 1 up with just 2 heavy rockets attached. But I had to engage auto pilot only at 18k up.

So what exactly is happening when you try to launch normally?

They crash and burn. Tried setting throttle to 50% and it works, but I end up with no connection to either Mission Control or TelSat 1 so....crash and burn. :huh:

Understand RT2 before trying to send satellites up. Understand rocket building before sending anything up.

Wow, I never thought of that. Here I was spending a couple of days reading the OP and all the instructions and tutorial materials on those subjects and it never occurred to me. Thanks. I'll try that out right now.

"I end up with no connection to either Mission Control or TelSat 1"

Obviously. You might want to hit up the last 5 pages or so of the RT2 reboot.

Not needed. The problem was having mechjeb do the launch for me. I had to activate the auto pilot only AFTER I reached a height of over 28k above Kerban. When auto pilot was turned on, it worked.

I'm able to put the satellites up now with no problem...As long as mechjeb isn't turned on when I launch.

Here's a tip I saw someone post recently for RT2: Put antenna and command pods on your lower stages. They can act as relays to Mission Control. It'll especially help in the early stages of a new RT2 game before you have adequate relays in place.

Is there any way to stop Mechjeb maneuvering when staging during a launch? If it's a complicated design and the rocket pitches during staging it can take out an engine bell or two.

That's why you use Sepratrons, rotated and angled as needed to push the spent stage parts away. The heavier the part(s) to shove away, the more Sepratrons you'll need to stick on. Be aware of what the Sepratron exhaust is aimed at or will move across as the spent stage drops.

Sepratron exhaust is quite destructive, which makes them useful for simulating a failure. Mount one aimed at a fuel tank or engine etc and when it activates you'll have rocket parts all over the sky in a couple of seconds.

A word of warning when using them with MechJeb, they MUST have a radial or inline decoupler in the same stage and the decoupler must stay with the rocket until it's time to fire the Sepratrons. Sticking an extra decoupler on a lower stage then putting its icon with the Sepratrons doesn't work because once the spent stage is out of physics range KSP removes the decoupler from the staging list , then MechJeb will go ahead and use them out of order.

Without a decoupler in the stage(s) with Sepratrons, MechJeb will activate them out of order, even if they are positioned to fire forwards. MechJeb will do the same with other engines not paired up with a decoupler, even though that works perfectly using manual staging.

Without having at least one decoupler in every stage that has engines (not every stage has to have engines) the way to block MechJeb from activating engines early is to set the Stop at Stage number to the stage below the one you don't want it messing with. If that's in the middle of the rocket you can manually trigger that stage then change the Stop at Stage number to allow MechJeb to continue automatic staging. Or you can completely disable automatic staging and let MechJeb pilot while you wait for the burnouts and pop the spacebar - and the staging will work exactly as if you were doing everything manually.

I don't seem to have the files/folders for MechJeb 2 in the right place. Could someone please let me know where they should be?

Thanks much!

The primary Mechjeb folder should go in KSP/GameData. If you are using MechJebFARExt then that goes in its own folder in GameData.

Feature request: Integration of the warp helper into the Maneuver Planner and a windows with a scheduled Maneuver list. Save and load of a Maneuver list.

If you want to save your maneuver nodes then get Kerbal Alarm Clock

Thanks for the help. :) It's working fine in Sandbox; which research nodes do I need to unlock for the more advanced modules?
