Hi Joe,

Thanks for your kind comments.

What motor are you using in your Delro?

The 20 x 13 RASA performs quite well in the Spark but I think I have the headroom for a little more grunt hence trying the different props. AXI recommend the 20 x 13 for the 5325/24 but with a maximum current of 48-50A I feel safe in moving to a bigger prop. I think the 20.5 x 14 is in between the 20 x 13 & 20 x 15 props load wise.

Cheers
Jason.
