Hi Members,
I tried this when the 520 came out, shortened them to match the 480 props and then balanced them . I made a jig to make all the same, but still took a bit of balancing. Long story short they were alot quieter and gave plenty more lift but we're too much load on the motors which got very warm compared to normal flights. So if any one is interested I have a set of modified props for sale. I decided if I wanted to improve the 480 I would buy the H plus or 520. The 480's that I have are still doing the job very well, should have saved the $ outlay. But if we don't experiment we won't improve. Johnno Hennessy.
