    The Voracity tuning thread

    I promised some guys in the voracity thread I'd create a thread on tuning and modding this awesome rtr boat I just got. Well here it is. Here's my plans:

    First I want to see if there's anything to be had with different props. I also want to see what we can do with tweaking the stock prop (which is a good prop to begin with. There might be a few other tweaks I'm gonna try. I also want to encourage everyone else to share their findings. This thread isn't just for me, it's for everyone.

    First things first. I already know there's a gain to be had with timing. However, the factory Esc (as good as it is) doesn't like it. So I had the perfect candidate to throw in there and get to testing. I may put the factory one back after I'm done testing, but just for safety's sake I'm going to be using a little higher amp Esc. While I was putting the Esc in I went ahead and changed the motor bullets to 6.5mm castle bullets. I mainly did this because it makes swapping things simple because I use these on everything. Next I used castle 6.5mm green connectors. That's what most of my batteries have so why not?

    I plan on doing some running this weekend if the rain stops. Here she is after I made some changes.....I re routed the cooling lines and had to reglue the trim ring for the cooling hose. It felt loose and was moving a little as I was messing with cooling lines. No big deal, pulled it out and smeared a little silicon on it to hold it in place and seal it.

            I too had to re glue the bulk head fitting for the water lines. I re routed my water lines and polished the propeller

                It came like that. Also in my opinion, I feel like the balance of the boat would be better. Weight lower in the hull is always better.

                  I got some info for you guys! I went ran it this evening real quick. I wanted to get a base line. Keep in mind I had it running wet but only changed props (once I got it running smooth) to see if there was a speed difference. I didn't get video because my son didn't want to come. I was in a hurry too. Bats weren't charged all the way either. But still.

                  So the stock prop, I had to adjust the batts and trim tabs to stop the boat from porpoising badly. After running it a bit, adjusting etc this is what I got:
                  1) stock untouched prop 45mph
                  2) m645 (basically a stock prop but s/b and detounged) 48.5mph
                  3) abc 1914 51.0mph


                  Edit. I forgot to put the temps. These were measured after cutoff voltage (3.75v) and using the big prop running wet:

                  Motor. 103.4f
                  Esc. 110.9f
                  Batt connectors. 94.5f
                  Batteries. 101.2f

                        Is the abc 1914 1.9" diameter with a 1.4 pitch?

                          Yes. Essentially 48mm. I didn't have a finished 1815 (45.7mm) to compare. I suspect it being faster. Find out Saturday.
