32" carbon rivercat single 4s 102mph, 27” mini Rivercat 92mph, kbb34 91mph, jessej micro cat(too fast) was
I got a CNC 5014 today in the mail and ran it tonight. I don't know a ton about props but I picked it because the total pitch is 2.76 and I wanted to see what a CNC prop was like. Noticeable torque roll when you punch it but seemed to run pretty well and it hit 55.8mph! I pulled it in a bunch to check temps and so I wasn't running hard the entire time straight. On 4S it ran 38.1mph
batteries - 110ish
esc - 117-120
motor - 110
motor wires/connectors - 165
battery wires - 105

The motor to ESC connectors are stock (I think they're 5.5mm?). The battery connectors I have changed to 5.5mm bullets. I guess I should have said that this is with the stock motor and ESC.
Yes, and I think that's why it has more torque roll. I decided to try it because the pitch is 1.4 vs 1.6 on the common Octura props so the total pitch is supposed to be less than the stock prop.
I spent a couple hours today cleaning up a new M645. It's still not very sharp but I had enough at that point so I went out and ran it. 54.6mph on 6S and 36.8 on 4S (stock ESC and motor). If you punch it from a dead stop, it will spin for about two seconds and then it hooks up and takes off. The delay isn't really a big deal and is kind of fun to watch. It doesn't seem to come into play in turns. I think there's probably more speed in this prop if I had it sharper. That's just a guess though. P.S. I still don't have the option to attach pictures to my posts. Do you have to have a certain post count first?

Sorry to hijack thread, but I am attempting to attach a .jpg that I've uploaded from my hard drive.

There is an icon on the reply toolbar for inserting an image. You don't have that?
I'm the one that hijacked it. No worries. No, I only have the option to insert an image from a URL. Same thing in advanced reply.
Went ran it again today. Made sure batts were fully charged. I made no changes.
Abc 1914 58.2mph
Abc 1815 56.9mph
Abc 1915 53.9mph

Interesting. Larger diameter at lower pitch came out ahead. I would have expected the 1815 to be the leader.
Important what's the amp draw on each . Could u run any of these on Stock e.s.c.
Seaking 180a? What Are temps
I finally maidened mine today.
Set up is this:
SeaKing 180
Hobbywing BEC
Speed Master billet trim tabs
Kinetic 4" rudder (for breakaway feature)
Two part foam and reinforcements Adding 1 lb to the hulls overall weight.
on 6s
M545 52mph
ABC 1815 59.1mph
My temps are low on the SK180
Ok, I just did some free mods and just realized the trim tabs were pouting a bit down and one more than the other. Explains why I had to trim the rudder a lot to the left. It's so close to 60 at this point, I'm pretty sure my few mods will put it in the 60's. Here what I did:
Sanded the ride area with 400 grit (paint is super super thin so keep that in mind if you do it....you will sand through in a couple of seconds)
Sharpened the rudder
Sharpened turn fins. One of mine had a slight gouge (my fault I'm sure) so I fixed that.
Charging batteries. Stay tuned.

Pic of mine with hardware upgrades.
Look great. Lot of excellent info in this thread already. Did those trim tabs and rudder match up to the stock mounting holes by chance?
