Hey there
Maybe late to jump aboard now
But im waiting for arrival of my Verocity

[Keagan-Z06]

It's never too late.

[fweasel]

It's never too late.

Agreed. I really like the boat. I have some new Dasboata props to try out now that the weather is cooperating again. I've got an ABC 1915*17 that people have already run and a custom Octura x450/3 cut down to 47mm.

[Keagan-Z06]

I got a x450/3 I just got from him too.

[BoredHD]

Im glad this thread is still alive
Gonna pick her up later from the lhs
Batts are gonna be a bummer tho
Most are 3s 5000mah with 30c discharge
From what i read it shd be minimum 50c?
Im using 2s 5600mah with 40c for my Miss geico 29

[BoredHD]

Woohoooo
Shes a beauty
Cant wait to launch her this weekend
Managed to get some 3s with 7500mah at 75c
Ill run her stock out of the box
We get pretty flat waters here
Besides greasing the shaft, anything else i shd do?

Picked up a set of Boca 5x16x5 ceramic bearings. My motor has been dunked one too many times. A cooling hose came loose last weekend and flooded the boat, which was the last straw. How the heck do I remove the old bearings? After a quick look, there doesn't seem to be any lip to press the front bearing out, and the rear is pressed into a cap with no center access hole at all. I suppose they could be pried out.

Mine was pried out bud. Stuck something in the holes at the top and off it came.

You can take the end with no holes, set it on a socket or something bigger then the bearing, put it in the oven at 250 degrees, you don't have to let it get quite that hot and then use a cooking glove to pick it up and slap it down on a hard surface like a board or something with the socket and all. It will fall right out. No damage done, let cool off and press in new bearing.

I had considered heat, but ultimately, the lack of access to the rear bearing for lubrication lead me to just drill out the rear cap. I used a 3/16" bit to drill the cap and was able to tap out the bearing with an appropriately sized punch and jewelers hammer. Popped the Bocas in with an 11mm socket, screwed everything back together, and had the boat back in the water today.

So it sounds like the ABC 1914 is a good sport running prop for the boat with all stock electronics?
I'll be upgrading the trim tabs and maybe getting a dual pickup rudder as well, just having trouble getting the boat up on plane. From a stop I can give it full throttle and it'll take 2-3 seconds to get up on plane.

I would say it's a pretty good start. I ran a 1914 on stock electronics last summer and I think it ran 55-56mph when the hull was really aired out with only just the last bit of hull in the water. The temps were all in check. I've been running a 1915 recently and while faster (62.2mph), it's putting a considerable amount more load on the electronics and my run times are only about 3.5 minutes if I want to keep the batteries above 3.8V. Today the ESC was about 150*, motor was 134*, batteries were 120* and the motor wire connectors were 220*. I then switched to a 450/3 prop that's cut down to 47mm and ran 57mph with cooler temps.

How was the handling with the 3blade?

I didn't change anything setup wise so not as good as the ABC. The octura appeared to have more lift in the transom, the hull ran wetter, and had some wobbles almost like chine walk.

[rcboone2000]

This is the setup that I have been running a dynamte1750 4 pole out of a impulse a dasboata2214 prop trim tabs above bottom of boat turn fins rotated back drive all the way up 2 heavy duty 5000 70 to 100 c battery as far forward as possible and a 180 amp speed control it will run low 70s without getting hot I will run battery Down to 3.4 volts per cell.I have have been running this setup for a year. The boat was a little faster with the stock motor but I burnt 2 up. Sand the bottom of boat with 400 sand paper.I also use some stuff on the bottom that we use on our real nitro drag boat it gives us about 3 to 4 mph

[rcboone2000]

I also use the same motors in zelos 36

I'm surprised no one else commented on this. Very bad to give it full throttle when getting on plane. Puts a lot of stress on things especially when it suddenly grabs.

2214? As in 2.2" (55.8mm)? Seems quite big for that hull, no?

[rcboone2000]

Yes I like the the way it runs with this setup I did have octura 452 on it but there was a lot more heat with with the 452.Kfx I know you know your stuff.I have also have been around boats all my life I have raced a lot at full size boats im 65 yrs old and I love to do things out of the the normal.Sometimes it cost me a lot of money but i learn what works and what dont

I'm the same way myself. Have you tried a 1915 or 2015? Maybe the reason that large prop is working for is because you have the strut raised a good bit. I recently figured out that if you run a higher quality and more efficient motor that you can get away with a little more than you can with those dynamite motors.

[rcboone2000]

I have the strut all the way up.I have tried both of those props.I have the 2015 on my zelos 36 with the 1750 4 pole impulse motors.I have even reversed the rotation of the motor just to see what happens

What do you think would be a great upgrade motor for this boat Travis?

I think a tp4060 1720kv would be a really good choice.

Awesome, thank you.

Good morning to all, guys,

I'm very happy to have bought Voracity, my first boat,

I use airplanes normally but too fascinating the powerboat ..

my best result top speed, is 45.98 mph with everything Stock,

but my prop slightly damaged on the tips after losing a rudder screw, I straightened by hand,

the batteries I use are the Quantum Series Sls, configuration 6s (2x3) 5000mah -65 / 130C a slightly heavy 492gr ..

I would like to figure out how to configure the tabs' setting (if needed), and buy a new propeller, perhaps an Octura x645 or an Abc 1914.

What advice do you have to give me?

Thank you and have fun at all.

Marco from Italy

[Revolt Flash]

When my Voracity was stock, I ran the trim tabs even or just slightly down depending on the wind. I ran an Octura x452 sharpen and balanced. I kept the run times around 3 to 3 1/2 minutes. Make sure you keep some distance between the dog and strut on the cable.[4 to 6mm] Have fun!

[MarcoZeta]

Hi Revolt thanks a lot for you reply..

[MarcoZeta]

I have another question for you..my stock esc work well but some friends ask to me.if this is unlocked for a full functionality and may a better speed. .Is it true or not? Need to buy some special program card?

Inviato dal mio SM-G900F utilizzando Tapatalk

[fweasel]

Yes, there is a program card, but for the most part, the ESC is setup properly from the factory and there isn't any locked potential to be had with the stock motor by changing settings. With that said, I prefer to have an actual program card on hand for each type of ESC I use so that if I do what to change something, I can do so much easier than using the transmitter method.

Oh, and I would recommend replacing that prop. I've used the x452 previously, but it caused a lot of torque roll. I like the ABC 1915 or 1815 17* props on the stock electronics with 6S power.
