Help with spaceplane drifting on runway (checked wheels already)

[Noblejms]

Hi guys, I am currently testing a space plane I built, which is designed to take off using propellers and then use rocket engines when it gets to upper atmosphere.  Unfortunately, I can't even get it take off from the runaway without severe drifting issue.  It all starts well, but after getting to about 30m/s on the runway, the plane starts to drift and very hard to take off. I checked that the wheels are all aligned so don’t know what’s the issue. Spent several hours to fix this problem, but my attempts so far had been unsuccessful. 

 

Of course, I checked the wheels and made sure they're all aligned.  So I don't know how to fix the issue.  Wondering if you guys could help me take a look if you have time?  I uploaded my craft to KerbalX.  Though I'm using mods, the spaceplane itself should be made of all stock parts.  If you could help me take a look, I would be very grateful!  Thank you!

This probably has something to do with the fact that the runway is flat, when Kerbin is very slightly curved, causing the drift. It should be going to the left, correct? Try tapping the D key periodically. There's not really much else you can do, it's not your fault.

Sorry for the brief description of the reason for the problem, it's hard to put this thing into words. I believe the official wiki goes into more detail in the page for the runway.

Hi guys and Clamp-o-Tron, I solve the problem with some suggestions from people on another forum.  The solution is to set front wheel friction to zero, disable rear wheel steering, and put a tail fin (vertical stabilizer) to counter the propellers at the front.  My plane no longer drifts now.  Eve here I come!
