The Voracity tuning thread

[paulfromtulsa]

I got the upgraded ose flex cable today. The cable looks to be stronger than the stock one and is made nicely

what is the stalk voracity prop in mm please!

[montymike]

Same as a octura x 645 so diameter 45 mm 1.6 pitch

This morning I tried a ABC 2014-10-50. The water was a little rougher than what is probably ideal for SAW passes. The wind was gusty. Stock motor and ESC. 52.7mph on 6S and 38.8 on 4S. I think there may have been 1-2 more mph to be had on 6S if the water would have been better but the prop wasn't that great. This is the largest diameter prop I've run and the first one that actually torque rolled the boat onto it's side while it was running. Between that and the chop, it wasn't ideal for top speed. It also take a while for the prop to hook up on acceleration.

After I saw that the 2014 wasn't going to run well I switched back to the Octura x452. I'm liking this prop. I didn't improve on it's 59.4 6S speed but it did run 42.2 on 4S today (on packs that had already been run with the ABC2014). Since the x452 is stock and has a full tongue, it accelerates great and is very fast. Sometime I want to run it harder for a full battery run to see how it would work for general bashing.

Stock boat, I was at 44mph with a Gens ace 5000 6s 65-130c just fueled up with a new pulse

It's am amazing what different batteries will do.

This morning I ran a Octura X455. Stock motor and ESC. Water was good. 59.4mph on 6S and 41.4 on 4S. Like the last prop, this one torque rolled the boat to one side. I noticed that it was rolling to the side my GPS was on so I swapped it to the other side and that seemed to help level the boat out on the passes. Still a fast prop but almost identical top speeds as the x452 and the handling wasn't as good because of the torque roll.

After I did the 6S and 4S runs, I swapped to a third set of batteries with only a 40c rating just to see what I could get out of them. The boat wouldn't do a full pass without going into ESC protection. The water had calmed down to almost glass so it might have just been drawing to many amps and hit the over-amp protection that Rafael has talked about. I swapped back to my main 6S packs and it did the same thing. It's possible that those packs were close to the low voltage cut off. Just a little strange....

Have you tried a 1915 or 1815? Those seem to be the fastest and most efficient props. I don't thing the motor has enough for a 2014. That's a pretty stout prop. Even a buddy of mine told me his 1577kv 1521 Neu on 6s was struggling to turn that prop. Evidently it's more aggressive than I initially thought. The 1914 and 1915 and 1815 do well.

[arrover]

Yes the 1915 ran 59.2 on my boat. I have not tried a 1815. The Octura x452 and x455 both ran 59.4 but I wouldn't recommend the x455 because of the torque roll. I believe that this boat (at least stock) likes large diameter, low pitched props. It seems like the limit on diameter might be somewhere around 2" before the boat starts laying over on its side. So far, these are the props that I've tested on my Voracity:

Stock Proboat prop
Octura x642
Octura x645
Octura m645
ABC 1817-17-45
Octura x646
Octura x646 detounged and cupped
ABC 1915-17-45
CNC 5014
ABC 1816-10-50 "turbo cut"
ABC 1916-10-50
ABC 2014-10-50
Octura x452
Octura x455

Wow you have a lot of props! When you ran the x455 did you go through a whole battery pack? How were your temps? I didn't think the stock 120 esc could turn that big of a prop without overheating. I am wanting to run that size prop in my Outrigger but wasnt sure if the esc would work with it. Any info would be great thanks

[arrover]

Hey Paul. No I did not run full packs through the boat with the x455. After I found that it wasn't as fast as the x452 and had some torque roll, I didn't run it much longer. The ESC got up to 125 degrees, capacitor pack on the ESC wires was 175, motor connectors were 145, motor 98. These temps could probably have gone higher but that's where I stopped figuring there just wasn't any reason to go further. Also, at least in the Voracity, the x455 seems like it is on the verge of pulling to many amps and putting the ESC into over-amp protection.

[arrover]

Reached my goal of over 60 on the stock ESC and motor! Actually stock everything except 5.5mm bullets for battery connections and OSE heavy duty flex (because I lost my stock flex). I ran the Octura x452 again to see how hot things would get and it ran 60.7mph on 6S. The water was a little bit rougher than normal and it was running pretty loose into the wind. I kept running it through one set of batteries, bringing it in every 4-6 passes to check temps, and then right back in the water. It was not race pace. More like sport running. Temps got pretty hot and one battery puffed slightly. My low voltage cut off is set as high as the stock ESC will allow and I did run it down to the LVC. I really like this prop. So fast and great acceleration. The high temps that I saw were:

Motor - 99
ESC - 115 (around 130 on the caps mounted to the ESC)
Capacitor pack on the ESC wires - 188
Motor bullet connectors - 170
Batteries - 118, 105

I think you guys might like this. New top speed for me:

Good job! Your the fastest so far!

[montymike]

Wow: nice job...

[paulfromtulsa]

Nice job arrover! My 61mph record only lasted a week lol. I wonder what it will take to get this boat in the 70's
