Hey all, I'm having trouble using the tri-coupler with this mod. Whenever I install it on a craft, the center of lift ends up offset to one side. I've checked it in my stock install and confirmed that the center of lift stays smack in the middle when adding a tri-coupler, so I think it has to be an issue with the way the lift generated by the part is calculated. Unfortunately I'm at work all night, so can't add any pics but I'll try and grab some when I get home. Is there any way to fix this, or should I just not plan on using tri-coupled rockets? Otherwise loving the mod, really like the changes to rocket design/flying (once I figured out how to keep my gravity turns under control)
