Like sebbe said, A small high rpm prop would haul the X faster than the "hotliner" setup.
But is it more fun? I dunno... Flicking the go switch results in big grins and swear words from innocent bystanders with the big prop and lots of watts
You'll struggle to find a 32mm spinner suitable for conventional pylon props BTW.
Id like to see (AKA build/fly) an X with an 8-10" high pitched speedcup prop
