Hi Skippers,
I am building a twin 6s DF41. I need to design the prop spacing so I am seeking advice about what size prop you think I may get to roughly as a maximum diameter without the props being too far apart. My previous twin build (Pirate on twin 4s 30000RPM ended up sweet and safe on 43mm 1.6 pitch props). I am thinking I may need about enough space to spin 47's or 48's on 6s at 31000RPM, but I would love to hear from some of the legends on this forum who have greatly assisted me in the past. I'm only after about 3 mins run time, but don't want to get too close to the smoke zone. We all know smoking is bad for your boats health! Many thanks Running Beer.
