I'll put my vote in for Hobbywing ESCs, I run a Justock in my XV and it's flawless. If you want sensorless, their EZRun ESCs are also very nice, I have one in a little Kemora and even sensorless I get no cogging at all.

As for motors, there are many good ones out there, but for my XV I selected a 10.5 SMC. The SMC motors are built by Dualsky and are VERY nice, especially for the low price. Smooth as butter too.

So why not do it right from the get go and save money.

One more thing to worry about? Its a wire, you plug it in and its connected. Without sensors you have to deal with cogging constantly.. cogging is far more inefficient than a hall sensor.

The inefficiency myth was created by Castle Creations to justify their ESC / Motors not having one. Sensored ESC switches to non sensor mode because once the rotor has passed its initial starting point, it is not necessary to know its position. Castle eventually ate his words and now sells sensored ESC as well.
From my point of view you won't have any trouble with cooging if you buy a good ESC. The ESC which came with the combo had al lot cogging and it wasn't fun, but with the Genius 75 you don't have any Cogging. It might be not as smooth as sensored, but it is nethertheless smooth enough for rallying and I am pretty shire that 2013 ESCs have a even better sensorless mode.

But all in all I think I'll prefer the sensored solution.
How does the justock fit the Xv-01s electronic Box?

Which combo would you prefer for the XV-01?
1: http://www.rcmart.com/novak-sportsma...0-p-33580.html
2: http://www.rcmart.com/novak-club-spe...m-p-36075.html
3: or the Hobbywing you stock, which costs 54 Euros down here with a LRP X12 Stock in 17,5 or 13,5 ( 40 Euros)

Does anyone know of softer-than-stock springs that Amain carries, such as this, for example:

http://www.amainhobbies.com/product_...ngs-22lb-Red-2

http://www.amainhobbies.com/product_...gs-17lb-Blue-2

I run mostly on a track I scratch out of a dirt driveway/roundabout, and find the stock springs bounce the car around with every bump.

I the super soft from top cad with 35wt Losi oil in the rear. The rear end doesn't step out anymore off throttle..

Thumbs up First Run.

My XV-01TC PRO is now rally ready!

I took it out for it's first run today. The track was really tacky. Even had a few puddles on a couple of the corners. I steered clear of those.

I had a ball. The car feels great. The track has been used by a lot of 1/8 buggies and was really rutted. I even almost cleared the double, just need a little more power. It's really surprising how well this car flies...

It was, however, getting heavier and heavier due to the amount of dirt and mud that was being held in the chassis.

I think I have either a skipping belt, or I need to tighten up the slipper clutch a little. It sounded like the belt but I'm going to check both once the cleaning is done.

The mud also locked up the rear left wheel, and caused a lot of binding in the servo after a time.









So let the cleaning begin.

Funny you are the 3rd person to use the E30 M3 as a rallye body on the XV-01... I just retired mine. Maybe BMW should have done a rallye version of the car.

Last year I did the same, ran it on an 1/8 off road track.. Car jumped great, left the track with zero damage.. Was thoroughly amazed.

I must admit, seeing one of the E30 M3s on this chassis was what inspired me to do it. It looks cool running over the dirt.

Hey guys,
Any chance someone can post a pic of steering on full lock? I have done a few mods and would like to be able to compare it to the original steering angle but didn't take any photos myself before I started. Too much cutting has been done to go back to the original setup.


For anyone interested I'm attempting a drift setup with this chassis. So far I am overdriving the rear wheels by 25% but also have pulleys on the way to increase it to 50% with the stock belt. I have more info on another forum but if you would like to know more I am happy to share more details here too :-).


Anyway, here is my current full lock. I don't think it's a massive improvement, but it would be nice to be able to compare to stock. Thanks guys!!!

Hey I'm interested. Can you tell us what changes you made and parts that you used. I plan on getting one to use as rally and drift.

They did and won the Corsica Rally in the late ´80s against the Lancias. As far as I remember, BMW rally cars were prepared by Prodrive, the same racing factory that prepared all the winning Subarus.

Sure

To overdrive: i'm using 16t and 20t 3racing pulleys (stock is 18t:18t). The limitation is the lack of slightly shorter belts (that i can find anyway), and the fact there is little room for larger pulleys at the front (photo below shows the room left around a 20T). I have a 21t on the way which i expect will just fit but at this stage i'm pretty sure 22t will be too big.

I also have a 14t pulley and will use this along with the 21t to get 50% overdrive (1.5 FCD). To aid in the tensioning I have also changed the stock tensioner to an 11t tensioner pulley. A 13t or slightly larger would have been a better choice though. With some tensionning innovations the FCD can probably go a little higher.



Wider Steering Angle: Required a lot of cutting and grinding.... I am using the tamiya aluminium suspension mounts and as you can see removed a fair bit of material from them. However, I changed the setup afterwards and removing as much as I did wasn't really necessary in the end. The photos below should give I better idea of the modding needed.

Other parts used were,
Tamiya steering bridge
Eagle extended arms 3860P15
Eagle extended arms 3860P15-8-LBL
Eagle C-hub 3862-88-LBL
Eagle Knuckle 3861-LBL
Eagle Lower Sus Arms 3469
Eagle Carbon Upper Steering Brace XV01-11-LBL
+ some random shims, washers etc and whichever wide angle universals you like. Although if I did it again i would pick something slightly longer than the 44mm's I have. They seem a little too short.

I could have taken the angle a little further by removing some of the center post with a cut in it and some of the carbon brace but I didn't really think that little bit more in was worth weakening the chassis any further.

Was that too much information? Happy to help if there is anything else you would like to know :-)

Very nice of you to share. Where did you get the 20t and 21t pulley from?

In regard to the axle lenght 46mm might be better. It seems like most drift setup are pushing 200mm. So if you got longer arms then 46mm axle might be better.

So, looks like you are trying to go for a counter steer setup right? What is a good ratio to be when it comes to over driving the rear?
