Lower the nose to double this distance. This should equate to 50-52 mph. If the air is smooth this airspeed will give you approximately 200 f.p.m. down on the vario. This method will provide a safe speed for your landing approach. Now for some final thought on safety.
All aircraft have different flying characteristics but all respond similarly to the basics.
You will find much lighter and more responsive controls in a 1-26. Keep a light touch and fly by nose attitude relative to the horizon. In all your flying, plan ahead and think safety.
