The Voracity tuning thread

Bet it would be fast as long as you used a 180a e.s.c.

I'm real curious to see some data logging on this boat

I will be logging on my next runs (maybe today) but I won't use a 646/3 lol.

That's cool
the stock prop has good runtimes and I bet does not pull to much

so 4614/3 was ok but a m447/3 will burn things down? If you round the tips it will condense the thrust cone and reduce the diameter which would make the specs just about identical except you lose the lowest pitch part of the blade that ultimately limits top speed. I'm still confused on why this is laughable. I will admit I don't run anything 6s but if my 4s boat can run that prop than I don't understand why a more efficient 6s boat couldn't do the same thing. I'm not saying it's a sport prop or anything but for a couple min at a time I would think it would survive. Oh well I have nothing empirical to back it up and no intention of getting a Voracity so I guess it doesn't really matter.

Respectfully id like to point something out. Just because a certain prop runs well on 4s does not mean it will play nice on 6s. 4s is approximately 24,400 rpm mildly loaded. You turn the same prop on 6a and that's 36,600 (yes over 12k rpm more). Do you really think the load wouldn't go up a bunch too? Just pointing that out because a lot of people don't consider that.

4s at 2200 kv is the set up I was refering to, I should have included that. 32,560 vs 36,600. The latter being less amp hungry because it has a higher voltage.

Two completely different set ups so I do realize the comparison isn't exactly fair but neither is comparing a 36x50 to a much larger motor. I'm also comparing to a boat that is 4 inches shorter so again, not apples to apples.

I'm off camping but the lake looks pretty crappy. I have a small area I can run in but I'm not sure it's worth it. I'm going to run the shockwave in it first. There's pipes and stuff sticking up out the water. The shockwave has a break away rudder so I feel safer running it first. If everything goes we I'll run the voracity. I hate to sink it with a $450 Esc in it. Lol

Let us know bro !

Ran it a couple times yesterday. Not quite sure why but it ran very slow. 44mph is all it could muster. I did change the strut position (without marking it like a dummy) and I'm sure that's what happened. Also in transport I think my trim tab position got screwed up. I really can't wait till ose has the billet trim tabs, I think those will be the best mod you could do to this boat. I'm seriously considering just getting the speed master ones because I don't want to wait. If I can I'm going to go run some more today but bring tools this time.

i did some gps runs today and the best i got was 48mph with a prather 225 sharpened and balanced. i only got 44 with the stock prop untouched.

It seems like the stock prop may be hit or miss? Do you think the boat is running to wet? I trimmed mine up a hair from the way it came from the factory.

I sharpened and balanced an Octura X646 this afternoon and ran it just now. 53.9mph on 6s on the stock motor and ESC. I didn't have my 4s packs charged. Here are the temps after about 2/3rds of one set packs. Seems that things are getting a little hot. What are the max temps that I shouldn't exceed?

Capacitors on the ESC wires - 190
Motor connectors - 170
ESC - 135
Motor - 120
Batteries - 115 and 120

My boat wasn't running wet at all. I actually did a few adjustment and those mph was the best iI got. When it was running wet i only got 41mph. When you ran your 646 did the boat torque roll at all or was it pretty straight? I'm thinking about getting a 6 48 but want to make sure the 646 wasn't too much first

[arrover]

My stock untouched prop ran 48.7 so maybe there's a wide variance in them. The x646 didn't torque roll to badly. I didn't really notice it anyway. I have run a 5014 on this boat and it did torque roll pretty badly but it still ran 55.8. I think you already switched your ESC right? I think I'm probably at the limit of the stock setup with the x646. The temps are concerning at least but I want to hear what the pros think.
