I was afraid of that, made a somewhat unstable ship to fly around the mun & it doesn't require alot of thrust & are low on eletricity, so wanted lower engine thrust to make sure I didn't run out before landing again. Also very annoying since I always forget to change the parachutes deploy height, & need to do that manually when landing higher up from water level.. Thank you for the answers though

First of all, perhaps this have been asked before or are easily fixable, but didn't find anything about it in the manuals nor by google searches.. Furthermore my english is not very strong so the explaining of the problem are probably not the best. Anyway the problem is that I want to change the thrust of my engines in the same stage, but are only able to change it one engine at the time.. (I know, not the most elegant or effective rocket, but that not the point) As you can see I have 4 Ion engine, but I want to avoid having to change 1 and 1 engine to lower the thrust, and then increase the thrust later when landing.. Can't find how I do that, but pretty sure I have managed it before, but that was, if I'm not mistaken, in the assembling process.. So is there any way to mark all the engines at the same time so the thrust changes for all of them when changing it for one of them? Thanks in advance for any answers
