I would say they do look like a nice hinge. Most poeple with larger faster aircraft use pinned hinges. thier just better. For my pt 40 I used the ca hinges in the kit with now problems. If youre new to flying, You are going to beat the pants off her . Most trainers dont last long enough to wear out the hinge anyway. I would buy them for youre 3rd airplane ,because youre second plane will be a low wing trainer. (Ive murderd 3 trainer planes before I could fly)
