As above is a Losi Excellorin 6.5turn and brushless esc combo (losb9500) . This came with a car i bought but is miles to fast for me.I have used it and is fully working. there is a problem with using the usb adaptor for updating the esc via a pc .This happened after a firmware update via there website but,this is a fault and can be rectified by sending it to horzon for repair if you want to.free of charge. It does however come with a programme card that works fine.Comes boxed with instructions
