Last night, I made a replica of the P-80 Shooting Star using mostly stock parts, with a few pieces from SXT, AirplanePlus, and Firespitter. I got it to look almost exactly right, only to find that the stock small jet engine I was using was far too underpowered to match the P-80's real life performance. So I decided to make one out of MODEL nodes.

I have the look I want, I have the performance I want, I even have the attach node at the right spot. But every time I save and load the craft, something weird happens: the engine jumps back about a meter! I thought it might be a problem with the attach rules, but I've tried it both ways and it does the same thing.

Here it is when it attaches at the node:

And here it is after a save/load:

And here is the cfg file:

You might try and add scale = 1 like

For future reference, if anyone else happens to stumble across the same issue, it turned out to be a problem with the attachrules. The ones I had before prevented it from being clipped, and so whenever it loaded, it sprang away from the clipped 0.625m tail pieces. Proper attachrules to allow it are:

attachRules = 1,1,1,1,0
