Lots of additional tweaks to make this a better-flying aircraft than when originally released.

Changes:
Wheel material
Aircraft material
Springy tail gear
Outer engine right thrust to improve/remove sliding due to lack of v-stab surface area
Adjust center engine position to correct roll more
Adjust center engine down thrust to fine tune trim
Many other minor tweaks. I think its much more realistic. Get a good long straight way to land... still not much control on landings unless at considerable speeds. Landing in a straight line is key to this plane.
