Hi Wireless,
I seem to remember the following
2300 rpm on downwind - about 85 - 90 kts (and trimmed)
On base reduce to 1500 rpm - maintain 1,000 ft (or whatever)
Speed in white line 2 stages of flap. Hold trim wheel at top most part and move to bottom (makes sense?) - do this twice and watch the speed settle to 65kts. Always worked for my instructor - hope that might help
