Spektrum DX5R/DX5 PRO UPDATE launch control for drag racing

I made a how to for the Dx5r and dx5 pro update. You need a clean micro sd card less than 32g and a Spektrum account in their website to register your remote to access download file. Backup your files or write down you’re profile setting it will wipe out you’re memory. Hope it helps ease the serial number upload to website #dx5 #dx5pro #dx5r #spektrumrc #rclaunhcontrol
