In a thread on TMP there was a discussion on building the Siler with magnets to swap out the anti-grav elements with tracks. So that's what I did. I got some rare-earth magnets from K&J Magnetics. These are very powerful magnets for a very reasonable price and I've always gotten great service from K&J.
Pic below shows the Anti-Grav elements with the K&J magnets in place.
Pic below demonstrates how the magnets are holding the Anti-Grav elements in place.
Pic below shows the base with the tracks glued onto it on the left and the underside of the hull with the magnets in place.
Pic below shows how well the magnets hold the flying base to the tank.
This Siler is a beautiful model and I'm very glad that Jon from Khurasan made it available as either a Tracked or Anti-Grav version. When you buy the tracked version with the Anti-Grav conversion, it's almost like getting a second Siler for just another $5. Stand by for pics of when I screw up the paint job.
