I have been looking everywhere for the performance specs of the RJ70 & RJ85. Im mainly after the take-off & landing distances at 1000ft. Thanks in advance

Have you tried looking at www.bae.regional.co.uk ?
You should be able to find it there.

Okay, it took me a while but here's what I found about the Avro RJ70:
