Question Booster cutoff?

[Wolfer]

I've recently been trying to attach 2 boosters to a core stage. A bit like in a delta IV heavy. I've been partially successful with velcro rockets and multistage2. The problem I encounter is that once the boosters have started, I cannot shut them off. This is a big problem since I am planning on using this stack in an interplanetary mission. So basically I was wondering if anyone here knew how to do such a thing. Or if there is a module that allow docked vessels to share their engine controls.

Never heard of anything that could do that.

Realistically though booster engines like the SRB have solid fuel, once started they cannot be stopped, (they can only be jettisoned)

Best thing to do is to limit the trust of the boosters or select a 'starup' amount of fuel for the booster altered to the mission.

If the boosters are working with Solid Fuel, it is impossible to control thrust.
Liquid Boosters can be controlled with the Remote Vessel Control or by changing Focus to them.

Perhaps I was not clear in my explanation. I am not using boosters properly speaking. I am just trying to attach 3 identical stages together in parallel burn. I am doing this because if I use only one stage instead of three, its mass would be ridiculously high.

Thanks, I think that's the best option I have at the moment.

Maybe the 'Vessel Stack MFD' is what you are looking for?

Just tried it and it works perfectly! Thanks a lot!

If you want to keep using only "Multistage2", you may do that by defining stages instead of boosters. This means they will not burn in parallel, but i guess you can trick it by having 3 engines as 1st stage (with proper coordinates for the exhaust) that burn for the whole Booster burn time. The second stage has only 1 engine which is the central core and burns for the remaining time.

I don´t know if that´s clear but I think you can do that by playing a bit around with multistage
