I can't take credit for this as a friend of mine told me about this.
Use the huge ship base and peg if you have one
This solves two problems.
1) The huge ship peg seems to fit more snug in the large ship
2) When flying the decimator if it's ramming ships you will no longer need to take it off its peg to prevent the nose of the ship from bumping other
And
3) Added bonus. It looks nice among the smaller ships at the higher elevation
Sorry if this has been discussed
Just read a post where the falling off peg complaint
Hope this helps
