I am running a pro zinger 18-8 and it hauls around the capx nicely. I am mainly running that because I had one... I have also tried a mejzlic 18-8 and it was ok too. I tried a 20-6 and it was not good. If I was going to buy a prop for this plane it would either be a Menz 18-8 or possibly a Menz 18-6. Good luck.
