Why do my planes lose traction and drift on takeoff, but the stock ones do not?

I've tried flying the Aeris 3A, and it takes off straight as an arrow. My planes, however, tend to veer left and right on takeoff. I've managed to take off straight on 0 friction control, where the wheels appear to have no friction, so my engines do not have a sideways thrust offset. I am using symmetry and have tried placing wheels on fuselage and on wings, rotating them to various camber or lack of camber. I even used the Hangar Grid mod to force align all of my wheels to perfection. Looking at my planes, they tend to be back heavy, but I've always built them like that in prior versions, and they do not drift. The actual aerodynamics of my planes are fine, but they just can't take off straight. Can anyone determine the reasoning? It's just frustrating that the stock planes function perfectly while mine do not anymore.

Here is one of my craft that exhibit this tendency.

This is my modlist, the only physics altering mod is FAR and I've had drifting without it.

For me when I moved my old 1.0.5 craft in I had the same problem, I was dealing with a spaceplane though not sure if that changes things any. I found that by having rear wheel traction at max 5 (so most traction where theres most thrust) and 0 traction in the front if im wanting to steer large landing gear it worked. If i didnt want to steer like when taking off I set front to traction of 5 aswell. My best guess is traction at 0 allows you to slide side to side aswell as forwards and backwardsand if you only have auto or 0 traction control on all wheels then your front slides left and your rear slides right and you wobble all over the place. I made a post here 

included a video for reference too.
