I feel that this site can use a revamp.
The upvote button can be moved to above the comment section, below the specifications.
Names of people who upvoted should be placed in an expandable tab as a "?” arrow.

users should also be able to remove comments from their own posts (delete hate comments, etc...)

under the "airplanes" tab under the menu, should also have a "tags" that should solve youtube planes, and keep the site organised.

Another suggestion should also be a "related aircraft" button. this can help new users whoes planes will be drowned out by many other users.

one idea i have is a new kind of user sorting. it can sort users from the most recently joined, number of points, comments or recent activity. this should help with creating opportunities for new users

mentioning the sorting of planes, there should also be an advanced search option.
Aircraft or not,
power-weight ratio,
VTOL?
Etc...
rather than just searching through tags which some users forget to use. again, should settle the problem of not enough upvotes.
