Fwiw, it gets better quickly. After your landings get better, you’ll rarely break a prop. I have a couple Tiny Trainers and rarely break a prop.
Try the ESC brake first. It’s free to try and doesn’t require experience. Next thing is to land a lot slower. Start your descent much further away from the landing strip and bring it down very gradually until you’re just a couple feet up. You ought to be able to descend with little or no down elevator, just reduce throttle until you slowly descend. If you descend too quickly, you pick up speed, and that breaks props. When you’re right above the ground, cut throttle entirely and pull up a little (flare). The flare is tricky because if you’re still going too fast, you’re immediately just climb again (balloon), but that’s a sign that you need to come in a little slower still. Eventually you’ll be able to touch down with the tail first and you’ll be going slow enough that even though your prop still hits the ground, it won’t break.
Good luck!
