# When should I perform the inclination matching maneuver?

I'm sending a manned mission to Minmus and, as Minmus' orbit is inclined to Kerbal I need to perform a maneuver to align inclination. From one of Scott Manley's newbie career guide videos I hear that I should do that as early as possible, i.e. at some LKO as it will be more efficient, but its not obvious why and at which exact point on the orbit (Ap, Pe, An, Dn being just a few possible cases). Thus my questions are:

• Why should the inclination matching maneuver is most efficient at low altitude?
• When I'm in some stable elliptic LKO, at which point of the orbit should I perform that inclination-matching burn?
• Going further, as I intend to go into a transfer orbit next, could it be more efficient to combine burns and perform inclination (normal) & transfer (prograde) burns at a single node?
• Scott Manley is the Chuck Norris of KSP - he's always right. If he's wrong, it's KSP that needs to change. But it sounds like he would be recommending a inclination change during Hohmann transfer from LKO. If you're using a maneuver node you can see that an inclination change at the same time as Hohmann transfer will add only a few meters of delta-v - free inclination change! If you perform a course correction halfway to Minmus you're looking at around 50 meters. Commented Aug 19, 2015 at 1:33
• He actually is doing this on his way to LKO, directing the rocket slightly south/north. But, for the newbies like me who risk spinning the craft out of control, inclination correction is suggested at the LKO. Commented Aug 19, 2015 at 8:59
• Once you know what you're doing, I recommend using MechJeb to avoid the tedium of minor course corrections. I have 700+ hours of KSP under my belt and I use MechJeb to perform simple course corrections like fine tuning planetary (or satellitic) intercept. These are best done at high transition nodes (usually half way between LKO and Minmus). Commented Aug 20, 2015 at 1:04
