monster warranty

[scooterboy]

Hi, my mamaba monster esc died today (while leading the 2nd heat after winning the 1st heat by 3 laps ) had a rather hard landing from the tripple drove for another 50 yards and died, steering works, but no power to motor or chimes when turned on :-(
I bought it brand new from an e bay trader based in the states last februrary but cant find my receipt (I'm in the UK), would a copy of my paypal transaction be sufficient?
What is the actual warranty, 6 or 12 months?

looks like i'm going to miss at least 2 meetings of the autum championship at least
