Hi Mike. Re the QuikR speeds on final, the answer is, it depends on the conditions and how your aircraft is set up.
If you have wingtips and no under surface vents, 70 mph. Avoid any crosswind landings though because those wingtips will catch you out. Without wingtips and having undersurfacee vents, you can come in at 65 mph and not worry too much about moderate cross winds. Use the trim to set up the approach speed so you can "feel" when you speed up or slow down. If no crosswind, a fully held off landing gives you the shortest landing run. I fly from Clench and can easily get in and stopped before the runway intersection (200 meters) 2 up without brakes. With a crosswind you need more speed and fly it onto the runway. If you have wingtips the crosswind pushes on them and creates a turn you will not be able to control if you do a fully held off landing and that can roll you over. You need a lot more speed to keep control, especially if you do not have the undersurface vents.
All of this assumes you are 1 up. 2 up changes things. Doing your annual check flights at max weight are very different and you will have more kinetic energy to lose. Approach speeds can be the same but rounding out and holding off requires a bit more runway.
Now when it gets windy (above 15 knots), it's all change again. You can increase your approach speed by about10mph, but rounding out and holding off is made more tricky because you can suddenly go up when it gusts and drop like a stone when it stops, so come in faster until you are just a few feet above the runway, then let the speed drop off and try to fly onto the runway rather than a fully held off landing but try to touch the wheels when you are below 50 mph. Practice in all weather conditions with every weight combination you can. I hope that helps
