I'm just going to go ahead and guess that the craft was built without the center of lift and mass being relativly equal. Also, more control surfaces and struts or even SAS would help, but unless you build it properly its not going to work.

All you need to do is add bigger sets.

Why cant you just put the old slots into custom ones

I suppose that since pilots have some sort of auto control now that people who don't use mechjeb can finally have some sort of autopilot(that isn't OP)

While I may have never used mechjeb before, I feel that some people are overestimating the difficulty of the game and just going to it. I have read some past threads that say thinks like " getting into an orbit, lifting off, landing, docking, etc is to hard" but the thing is in stock ksp, it really isn't. Also those are essentially core gameplay elements your taking away from your self. I guess if your a scot Manley and have the biggest space program ever and done it a million times, go ahead and use mechjeb. But if you arnt doing orbital manuevers in the game because they were "hard" doesn't mean you can learn from your mistakes. Aldo we have tutorials( hopefully more soon) and community videos. Anyway, just my two cents
