Welcome to GTM! These days the various RA2 discord servers are more active than this old forum I think, so if discord is your jam it might be worth joining through the invite link on GTM's home page.
It's always nice to see stock bots! To embed your images in your post, put your cursor where you want it to be in your text and click the 'Insert Attachment X' link next to the file in the attachments section of the post editor.
I haven't played stock in so long that I can't even remember enough to give you any solid advice, I'm afraid. Are you able to lower the chassis height at all by stacking the control board in the battery? If so it might be worth a shot, even though that stack is a pain in the ass IIRC (I mean you could just cheat with RA2CF but where's the fun in that )
I really like the shape of it, not much else to say really. Just really top quality work, as always. If I were to nitpick, the front wedge looks a tiny bit tacked on and it would be nice if the yellow top panels were flush with the chassis outline
stock isn't even completely dead. ms2 has his own live streamed stock tournament/ruleset that pulls in a decent amount of new users to ra2, and is also fairly active with people posting stock bots everyday
gtm just really isn't a part of the ra2 community anymore
