Mystic C5000 1140mm new projet build

Recently ordered a pair of 5514/3, they were looking good. From my experience I know that especially the Octura X447/2 works great on hulls like the HPR06 or the Mystic C5000 with 1140mm. But can give it a try, PropShop Props are very good. If you need them completely RTR I can recommend to have them done by dasboata.

@nata2run: Mhh I think I know which props you mean. It was a pair of CMDI 4773/3 CNC props by Andy Brown, made of 7075 T6 Alloy. But he quit producing these, from time to time you can find a used one for sale. On the HPR06 2Face the standard prop was a pair of X447's and on the Golddigger a pair of X457's cut down to 50mm which we recently changed to a pair of X450/3's.

Best regards,
Manuel

Thanks Manuel
can you please let me know the differences in total pitch of a 47mm 1.4 pitch 2-blade from a 47mm 1.4 pitch 3-blade?

Which one will have more spreed?

Thanks

Nick I think it works by multiplying 1.4 x 47 to get 65.8 total a 3 blade 447 has 32.9 more over all pitch so a total of 98.7. Then a 98.7 pitch should equal a 70.5 2 blade, so quite big. I think I got it right, its something like that anyway. A 445/3 should have 94.5 total pitch

If you run the 447/3 you might blow something if on 6s, something is gonna give. You don't want that nice new boat to catch on fire. Stick to 445 or 447

Thanks Kent
I will start my setup with a pair of x442 then will go x445 and if everything is fine regards temp of the motors and esc then I will try the x447 with 4s lipos and then higher lipos.

[nata2run]

445 is no issue for the Leo's if around 35k

[ManuelW]

theoretically a 4714/2 should give the same speed as a 4714/3, thats the idea. Practically this is not the case, sometimes a 2-blade can be better and sometimes a 3-blade. It depends how good the prop suits to the boat and the setup, therefore it may work efficient or not.

Best regards,
Manuel
