Unicorn - Mega Prop Suggestions

[poobear]

I am about to build the 48" Unicorn with the following setup:

Mega 16/15/4
Castle Creations Phoenix 25 Speed Controller
Thunder Power LiPo 3-Cell Series 1900mAh

What props would you suggest I try?

I don't have the prop adapter yet either. Is a prop saver a good idea?

Thanks for the help!

it depends on your altitude but i would say 4*4 5*4 or 6*4
