The Voracity tuning thread

i just hit 60.2mph with an abc 1915 prop! the boat ran awesome with not torque roll .

Nice Paul! You are the first! I have had a 1915 on order for a while now. Can't wait to try one!

Mine has been steady losing speed. I wasn't sure why. Well I found out why over the weekend. With the esc I have the wires on the motor and esc are short so the wires any pretty much straight across to the esc. Evidently that wasn't a good idea unknowingly. The insulation on one of the wires rubbed through and started grounding on the can. The last couple runs I was getting some serious amp spikes and lots of heat. I'm sure I ruined my mgm esc in the process. The last time I went to run it, it shut down on me for a few seconds. Then I babied it in and looked it over. My son talked me into letting him take the motor apart (I have a new spare anyway and I think he just wanted to see how it was built...so did I hehehe). So after looking it over and analyzing the build quality which was very high quality looking, just like a castle or older neu except six poles, I saw where the wire cut through. At this point I just haven't had time to fix it.

Nice Paul! Is that with the stock electrics?

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.

Nice Paul! Glad you like that 1915. I lost my flex and a new ABC prop on Tuesday morning. OSO HD flex and a replacement prop should be here tomorrow.

I raised the strut as high as i could and i got 61 mph then my flex cable broke. Luckily i didn't lose my prop. I Also have an upgraded ose cable on order. I am using the stock motor but have upgraded to the seaking 180 esc rabosi

I received the OSE HD Flex cable and replacement prop today. It's a nice piece. I like that its a little longer so it inserts further into the collet. It comes with a brass bullet nut but I chose to go with the OSE-8135 "OSE Locking Prop Nuts 10/32". They are tight on the flex threads (like they should be) but they work fine. I have read that bullet nuts don't help at all. If you guys have experienced good results, let me know.

Tonight I ran a Octura x452. It ran better than I expected. 59.4mph on 6S and 40.3 on 4S. Still stock motor and ESC. That's just barely the fastest 6S speed I've run but it's the first time I've had it over 40mph on 4S. The water was very flat so there might be a little bit more in this prop with little wind ripples. Very little prop slippage out of the hole since the X props have a big tongue.

Temps after 4 sets of up and back passes
Motor - 120
ESC - 114
Capacitor pack - 160
Motor Wires - 150
Batteries - 102, 104

How about the torque roll with that large prop ?

[arrover]

It didn't seem that bad actually.

Cool. Seems like the OSE flex might be a required upgrade.

I ran a ABC 1916-10-50 this morning. The water was flat so the speeds might be a little low because of that but still, not very fast. Stock motor and ESC. 49.7mph on 6S and 34.4mph on 4S. Lots of prop slip.

Temps after 8 or so passes:
Motor - 105
ESC - 121
Capacitors - 165
Motor wires - 170
Batteries - 99 95

A 1916 is not a good choice for this boat. I've noticed that the higher The pitched the abc prop is the faster it wants to go before it hooks up. The 1915 is a much better choice at this speed and rpm. Ideal? Not really but still a fast prop. I did talk mr Jim into making a 1914-17-45 which is going to be a better choice. The should be done next week. There's also a 3 blade coming that's very similar to the octura 447/3 but it's going to be faster and more efficient. I'll keep you guys updated. I'll likely get samples to try.

My testing agrees with what you say. The 1915 ran 59.2 on my boat and 60.2 on Pauls boat.

When the new 1914 comes out it should be faster because it will unload the motor more. That's my prediction based on a depitched 1915 my buddy just ran.

I'm very interested in that prop ..
