WOW thank's this will really help.

Just found Motek for 180cm but it still needs VBOX.

Motek HH Motor for 180cm

Sorry did not see this Motek .

Might be better to go 180cm as I can mount it on roof and mounting does not equate to extreme measures / concrete etc.

3 feet x 3 feet brick chimney might be best mount place , or even on south facing slope of roof.

Thank you again.
Sorry for the last post I was just as depressed as a chicken laying a ball bearing. Better now.
