I've got a Villain IV, upgraded to evx 2 emaxx 21 turn motors and new u joints, it still chine walks on me, it pulls really bad to the right at full throttle , i can hold the left turn stick about half way to keep her straight but the boat has a bad lean on it. I've tryed trim up trim down trim in the middle and it still does it. any ideas on what i could try next to fix this problem? I had 20 tooth pinions and went back to the 15 tooth gears and it still does it, It will chine walk on venom 6 cell 3000 mah a little, and with the lipo 5000 mah 7.4 volts its horrible. the props are brand new no dings dents nicks or scratches either. The boat even has a pretty good riding surface still in tact with the water when it chine walks as well.

Wooley, i hope someone with more knowledge than me helps you out, im at a loss for whats up. As you know i have the same exact setup as you, 21T, evx2 etc................You may have to call Steve at offshore electrics. I keep watchin this post.

Are the motors spinning opposite of each other? One clockwise the other counterclockwise? Sounds like both are spinning the same direction. That or the motors arent matched up.

Im beginning to agree with chimaira, i think you may have one motor spinning much faster, your counterclockwise motor may be newer and faster, the clockwise may be more worn and slower, also due to the fact its clockwise to start with, they sell a reverse rotation motor for $18 bucks. You could be running 3,000 rpms, or so, different. Heres what i did..............i think i may have mentioned this to you in the other thread, its not real scientific, but i took my motors out and ran them off of a 12v lead acid battery, and "listened" to the tone/speed of each and they were very different one way, then i hooked them up opposite and they were dead on the same, so i went with them that way. I wont hurt to check it out, all you have to do is take out the four screws and pull them out, you've come so far it wont hurt to try it.

also do your props spin away from each other or towards each other? whichever it is try changing it to the other way just swap props from one sie to the other and change motor polarity accordingly. you may also have a bad speed control sending more voltage to one motor than the other

I'll have to give that a try rebuilder, did you leave the pinions on for that or take them off?
Samich, the speed controller is a brand new evx 2, the right prop spins clockwise and the left counter.
for the motors they are both standard rotation, the one i just switched the wires how the old setup was. Im really lost on why it is doing this other than maybe one motor is spinning faster than another.

I believe the erevo motors have 15* advanced timing. So just running one in reverse, it would be slower than the other. Hopefully you just have the motors mixed up. If not you may have got two with advanced timing.

Here is a thread that supports my thoughts on the timing. Its funny cause Traxxas official says it doesn't but the motor part number shows it does.

If you look at the motor positions in the Erevo you can see the motors run the same direction, that the reason they have the timing in those motors.

It probably doesnt matter if you leave the pinions on, but i took mine off........once again, you will hear a "note" or pitch the motor makes, i keep that pitch in my head and quickly hook up the other and compare. I am not saying this will work for sure, but it worked for me. Your props are spinning in the right direction as i saw in your pics on the other thread. The e-maxx motors are made to run c-clockwise, and your spinning one clockwise, im almost certain they will be at different rpms. Worse case scenario you could buy two new Ex marine replacement motors(one for each direction) for less than $40 bucks, thats a small price considering how much you've spent so far. Go to www.thefind.com and search titan reverse motors and standard motor.

try setting it up so the right one spins counter clockwise and the left spins clockwise. that is if your looking at the boat from the back looking at the drives. it will only take a few minutes to change the props around and reverse some wires. it may fix your problem

The e-revo needs one reverse motor with its setup, the one in the front of the photo is a reverse model. If both motors were in the same side of the spur they would turn the same way.

the motors are emaxx motors, nietherare marked for a reverse rotation. im going to pull the motors and put them on 12v and listen to them. also switch props and wires to reverse the 2 sides

Opps your right, the Emaxx has the motors on the same side. You can actually see on the motor label, on the erevo pic, the front one has "reverse" showing.

So get the erevo motors instead of emaxx motors

It is possible your rudder servo is not holding under load..
I have a cat that did this, and when I went with a stronger MG servo, the issue went away!

FE baots are loads of fun

I have the JR z590m servo in there, its pretty strong i think. plus when i hold at a steady speed you can see the boat go side to side like one prop is pushing more than the other.

here are the specs on that servo

Z590M Torque Race Servo: Metal Gear Specs
Size Category: Standard
Type: Analog
Torque: 70 oz/in @ 4.8V, 85 oz/in @ 6V
Speed: .18 sec/60° @ 4.8V, .15 sec/60° @ 6V
Dimensions (WxLxH): 0.73" x 1.55" x 1.46"
Weight: 1.6 oz
Motor Type: 3-pole ferrite
Gear Type: Metal


I am not sure what the voltage would be considered as since I am running no seperate battery to the receiver just 2 two cell lipos 7.4 volts each 5000 mah

Hey Wooley, look what i found...............i'm ordering a set for my villain, neutral timing (runs same rpm's both ways) more power according to the chart and by the guy on the traxxas forum who tried them, I love Johnson motors, you just cant hardly find them anywhere................he said when i order to let him know what length leads i need and will put that length on with the gold bullets on the end.

haha bay city thats kinda close to me but not so much. That is a good deal but for now I just have to stick with what I have until I get some extra money, I still havent even gotten the landing skids for my raptors 50, and thats all I need to fly that again lol. I have many projects goin on. Thanks for the link though I do appreciate it!

I could always sell the motors i have now......

If you want to wait til i get mine i'll let you know how they do..............they have 59 sets available according to their listing, Also, the reason i'm getting them if you're wondering is because mine are tired, they ran in my e-maxx that i bought used from a guy on e-bay who probably was real tough on them anyways.

alright yeah sounds good, only thing tho we have pretty much the exact same setup but mine still chine walks [&o] thats y i think i need an adjustable motor to work the kinks out.

I dont think you need an adjustable motor, you need motors that spin the same rpms as each other while going opposite directions.

That's abut the specs of the servo I was using, now about 200oz at 6v and it holds strong!

It is very possible you need a reverse motor from the erevo..
I'm not sure if these motors have any timming in them, if so this is the problem as one motor, the reverse one is not spinning as fast as the forward motor..
http://www3.towerhobbies.com/cgi-bin...?&I=LXVDT4&P=Z
the emaxx uses two forward 550s, but the erevo needs one forward wired and one reversed wired to run at the same speed..
both the emaxx and erevo use the same forward motor

I've looked at those motors but unless they change something on the insides, the only thing different is the wiring to the poles is backwards.

have yoiu checked the solder on the wires to the motors?

also if you servo mount is some what loose, the rudder will drift..
