Have you experimented with other 24x10 props? I never had good luck with Bambula or MSC, the load appeared to outweigh the performance in my opinion. I had better luck with NX or Xoar Laminated. You can make more thrust with more load at a lower RPM and slower spool up, or more thrust with less load at a higher RPM and snappy spool up. I reach the goal happily with different methods depending on the model. Some simply perform better with higher loading props, and others the opposite. Mejzlik carbon props pull pretty damn hard for a relatively light loading prop and spools up nice. I'm starting to play with the th (thin) blade series props in 24, 26 and 27 inch sizes, and so far I am happy with their pull, while lessening the load on the engines. I like the quicker spool up and the engines are running cooler.

If you could make the ground clearance work....I'd think about a 26x10th I'm surprised you are not turning that bambula a bit faster, to be honest.
