The Voracity tuning thread

[Brushless55]

Yes but I was trying to get the boat back to where it was in the beginning first.

Well tonight could have been better. I was testing a new ABC 1816 "turbo cut" prop and the GPS kept losing signal. A couple runs showed in the 49mph range and then on the third run I was a lot closer to the opposite shore than I meant to be and hit a floating tree that was about 20'x4". Canoed over to the upside down boat and I thought everything was ok until I noticed the crack on the transom. It's really not horrible considering I was probably doing 30-35 at the time. After that I still ran some 4S packs and it ran fine. Once I got home I noticed a ding in the new prop.... The rest of the hull only has some tiny tiny chips in the paint. So the prop sucked and I wrecked the boat. I'm a little mad at myself right now.

Yeah, that should not be too bad to repair. One thing I noticed is that I can get about a 5 mph difference depending on batteries. Dinogy 3S 5000 65c in series was 48.3 mph. Revolectric 6S 3700 70c in parallel 52.4mph. Everything else stock. I love the boat though, especially at it's price point.

Sorry about your boat man, l have cracked one of mine up before.

[arrover]

Thanks guys. I don't think it's to bad and the boat is runnable as is. It looks to be mostly just cracked paint and the epoxy holding the top deck to the hull. ProBoat built a fantastic package in the Voracity. I wonder why they didn't spec a flip up rudder? Do you think it is a cost issue or are there other downsides to a flip up rudder?

[montymike]

Same reason why they didn't put bigger speed controllers cost!

Tonight I tested a detounged and cupped Octura x646. I thought this might be a good prop but the diameter has been decreased to 42.75mm. It only ran 50.2mph on 6S and 32.9 on 4S. I didn't write down any temps because it didn't seem like the prop was taxing the system. So it had been a while since the boat had ran a higher number and after the crash yesterday I wanted to make sure everything was ok. I put on the ABC 1915-17-45 on just to check. It ran 59.2mph on the same batteries that already had several passes on them. I was amazed. Still stock ESC and motor. I think the water was just a touch rougher with a little more wind. It must have freed the boat up just a hair more.

Man i think with good water conditions you will be the first to hit 60mph with your 1915 prop. I am going to order a 1915 tomorrow

I saw last night that OSE has a upgraded HD flex cable listed for the Voracity for $35. So it's stronger than stock and cheaper than Horizon. My flex is working ok for now but I did spin it in the collet a few times before I learned that the cable tip needs to be cleaned and the collet should be pretty tight. Thought you guys might want to know.

I thought the factory cable looked pretty stout myself. But that's good to know. That will be much easier for the newbs.

Great thread keep it up.

Great thread guys keep it up. I just flipped mine a few days ago and taco'd the canopy broke one pin out of the front of the canopy and cracked up both sides guess its time for some carbon reinforcements :-( I'm stock configuration and getting mid fifties with 6s2p and with a magic massage and balance on the stock prop and balanced the coupler/cullet took quite a bit of material off to get it running smooth as butter without vibration. Love this boat it's a Blast to run!

I'm thinking it would be a good idea for me to reinforce my canopy also. Guess that's the next thing I'll be doing.

I decided to add a little more floatation just in case. 1" foam pipe insulation with 3/8 wall thickness fits great in the sides of the hull. It's just the right size to slide up beside the existing foam in the nose and fit in the gunwales. My left side extends back to the cooling water exit and the right side goes way back to the servo area. The insulation is so cheap ($1.25) that I thought it was worth it.

Pool noodles also fit snug in those spaces. I ran mine today with a couple props. 55mph with Octura X645 s/b. 55.7 mph with Octura M447 s/b. 6S packs for both run. 6S 3700 x2 for X645 and 6S 3200 x2 for M447. Stock prop got 52.4mph with 6S packs. Originally I ran Dinogy 3S 5000mah 65c in series. 48.7mph with those and they got hot and puffed slightly.

i just hit 60.2mph with an abc 1915 prop! the boat ran awesome with no torque roll . the boat was gliding on the water. i am very happy with this prop.
