View Full Version : How fast?

I have never seen a hobby-style r/c boat run before. I have traxxa rustler. I just want to know how fast is the Villain?

40 ?
Maybe, but that would be the very extreme upper end of the scale.
Dang, I really need to get one of those radar guns. I am fairly certain I have the fastest Villain ever assembled http://www.traxxas.com/ubb/wink.gif I would like to see accurately how fast it goes. On my web page I declare 35 MPH with 6 cells packs, but this was a rather unscientific statement. We conducted the test by stop-watching the time through a given distance. The person with the stopwatch was a human and could not stand at both the beginning and the end of the trap, so error is certain. We did the test like 5 times. I averaged the numbers to reach the 35 MPH figure.
Where to get a cheap radar gun ?

jeepinator,

what turn motors are you using? although your villain is fast, it is not as fast as possible. if you had a super rooster esc from novak (which has no motor limit and forward/reverse) and like some 3 or 4 turn motors with 7 cell batts, i guarantee you it would be in excess of 40mph. radar guns can usually be ordered from mail order companies or somewhere online. don't know exactly where though.

You need to suck-up to a cop and ask for his radar gun for a day. It helps when your first cousin is the shariff!

the villain can do around 15mph or so in its stock form. with mods it can do in excess of 40mph.

Sirs,
Hydrodynamics is a very complex science. For sure there is an exponential function between power and speed. If 10 units of power yield 20 MPH, 10 more units will not yield 40 MPH. If 10 more units added 10 more MPH, for a total of 35 MPH, at 40 MPH 10 more units would add, say, 2 MPH. In other words, there is a diminishing return.
I tried 12 turn motors for a while. All that happened was super short runs, smoking hot motors, and a very slight speed increase.
I tried 18 turn motors. I tried 15 turn Reedy Sonic motors last. The Sonic motors have the large comm and seem very well suited for the high, constant load boats require. The 18 turn motors worked quite well, but the Sonics got the same run time with slightly less speed that the 12 turn motors. Read my web page, it's all there.
Anyway, I promise you, anything less than 14 turns or so will not yield any appreciable speed increase over something in the 15-18 range. One attribute of having more turns is MORE TORQUE, something boats require tons of.
I have run my boat with up to 12 cells. 12 cells was just downright silly. I actually ruined the two 6 cell packs I put in series doing it. The shrink wrap melted right off ! It was mighty fast, but 3 minute run times is stupid. 8 cells seems to be the magic number with the 15 turn motors.
Don't think that I have not spent in inordinate amount of time and money finding the solution that is resaonable (5 minute run times or better, doesn't burn up the brushes or batteries in one run, etc) and very, very fast.
Short of a brushless solution, I feel that I have the best combination of motors, gearing, and batteries (15 turn Sonic mods, 8 cells, 2 teeth less than stock on the pinions).
Like I mention on my web page, I can beat a 3.5 cc tunnel hull boat in a straight run. Of course as soon as we need to turn I get wasted. I have had sooo many people wonder what in the HECK I have in that thing for juice http://www.traxxas.com/ubb/wink.gif

Jeepinator what is the address to your website? I want to check it out since i am new to boats. Thanks

jeepinator, I have been to your site and love it. However, I would not take alcodesign's advice with the Super Rooster. The Super Rooster will only handle 10 cells, so running in series with two 7 cell packs is the equivalent of one 14 cell pack, which will burn out your Super Rooster within the first run.

The ESC you mention at your site is the Tekin 432M, which from my experiences is an excellent site and will handle comething like 20 cells with no motor limit. Stick with this ESC.

For hitting the 40 MPH, some modifications will have to be done with your boat. Running with Octura propellers is a must, along with bearings and aluminum strudders. With two 7 cell packs and 9 turn Reedy or similar motors you should be in the upper 30's and low 40's.

Guys, I've been gone a while, but I remember posting about the Super Rooster not being able to handle the Villain if it is wired in series. I also remember making a post explaining the 40 MPH mark.

If you are directing this at me, I don't understand. I don't want a Super Rooster.
9 turn motors ? Did you even read my above posts ?
If you have put 9 turn motors in a Villain and seen substantial gains, without burning something up, I don't believe it. I shudder at the thought of you even recommending such a thing. People, DO NOT put 9 turn motors in your Villains.
Sorry if I am being rude here, but that is just simply bad advice. Besides, do you want to play for more than 3 minutes, not have to change the brushes every run, and break stuff ? OR, do you just want a pretty darn fast Villain that is easy on parts, is stable in the water, and will run 6-8 minutes on a pack ?

BTW, CChase86, while our opinions differ, I do appreciate the compliments. Let's just not get overboard here ! (get it, hehehe "overboard" http://www.traxxas.com/ubb/wink.gif )
