Thanks for the advice, I got in touch with the distributor in my country. They are gonna try and get me another fan even though the fan is a non replaceable part. Bbloody annoying that the fan has failed within 3 battery packs.Unfortunately yes, call warranty AGAIN and have it replaced. I've all but lost all confidence in the Arrma electronics.
Nope no water, totally dry.did you run it through water get the fan wet?
