Yeah, it's true... But running your boat in salt water sucks! It's just hard on your running gear
I had to give the Motley Crew a little love today...I ran 47.5mph today with the 1800kv stock motor and x642 prop so I wanted to update my post from a few weeks ago that had prop speeds for anyone who cares...lol
Done a few test with different props and the replacement 1800kv motor if anyone is curious on the speed differences between them on my set up. No strut adjustments were made only prop swaps and the test were all done on the same exact day and water conditions (average with some mild chop). The boat still has more in it but I wanted to find out which prop I liked best and be faster for me then I will fine tune the boat for maximum speed without blowing over.
Batteries 2x Zippy 2s 5000mah 45c
42x55 Grim 43.6mph (sharpened and balanced by me). This prop would probably get 44.5mph with the nano tech 6.6 batteries since they traditionally pull another mph than my others
Prather 220 s&b 39.3mph This run was on the packs that I had already ran 3 laps on with the 42x55 prop, so maybe add 2mph more if they were fresh charged batteries. This prop got out of the hole very well with very little cavitation if any at all.
x642 s&b (Dasboata) 45.2mph
Batteries 2x Turnigy nano-tech A-SPEC 6600mah 2S 65~130C (these batteries always log one mph more than any batteries I use in this boat)
x442 s&b 43.1 mph
x642 s&b (Dasboata) 46.1mph
Battery 1-4s Revo 435 blend 5800mah
x642 s&b (Dasboata) 47.5mph

You should use the same batteries for each prop test. You'll have more accurate results that way.
Thanks Johnny. I knew I forgot something. see the above post. I updated the other speeds on the x642 s&b

Good to see the winner is a Dasboata prop and Revo lipo's.
Out of that group, the 642 will have the best top speed
Good amount of pitch
When I ran a X645 it was awesome! LOL

Did the x645 have more top speed of any you used? Any cons of using the x645?

Another data point: my own MC uses the AQ1800 motor and a 4S1P5000 pack. With the m445 it hits 47 mph and can complete a 6-lap NAMBA heat without excessive heat on a 95* day - and win. The m545 only added one mph. Switching out to an m645 it tops out at 53 mph but after three laps it has reached the same temps as the m445 did after 6 laps. Not a prop for Texas summer racing, but in winter it performs awesome on the race course.

That's interesting, the m545 loaded the motor more than the 645... would be interesting what an rpm data log between the two showed...
