Been flying a mag 28 on a combat plane with a 10x4 apc. Little slow but pulls well. However I have another hat trick R/C choker with a 64" span and a mag 28. I also have a mac's header and quiet pipe for this combo. What is your recommendation for a prop on this combination. I understand that the pipe performance is matched to a specific prop/plane combination so I'd like your opinions on the prop so I can max the pipe to it. Thanks.
