I own an M12 and the trigger broke on the remote. Where can I get it repaired?

I went to the following page but it doesn't work - http://www.airtronics.net/index.php/contacts/

I can repair it myself, just need to order the part and can't get a hold of anyone at this company

You might want to try Sanwa instead. Airtronics was really just their U.S. distributor. I can't confirm they'll have the part but they'd be your only bet other than finding one on ebay or in the forums.

their phone number is on this page. try calling them.

Airtronics technically no longer exists. When they closed their doors, Desoto Racing / Serpent America was named the US Distributor for Sanwa. Shoot them a message and they should be able to get you the part you need.
