XV-01 which carbon motor stay?

[Andreas W]

I am about to mount the Hobbywing Justock motor in my XV-01 and have found out that my research has not been sufficient. I have also found out that this is yesterdays news (not for me, though).

 

I can grind off a little of the OE motor stay,  but I see that others are using the carbon part from the FF. Then the question is which one will fit? I have found the partfor FF-03 54259. Is that the right one?

Haha.. i experienced the same thing… so ended up getting tamiya tble02s brushless motor… but would love to know if 3rd party part helps mitigate that issue also.

Hehe. It was exactly your thread I saw earlier today. 

 

I have dryfitted the motor together with a 64t spur and 27t pinion and found a position which seems to give the necessary space for both the sensor cable and motor tabs. 

 

I have also filed off material from the OE motor stay and it clears all ways now. 

 

The end solution is the thinner carbon stay,  but this will work to begin with. Now fill the diffs with 30K and 1K oil and it can come together again.

Cracking work! This looks like a candidate for 3d printing (or a bit of home cutting of sheet material if it can be done in plane but I'm guessing it'd need to have a bit of a step in it). My motors fit (TBLM) but I might stick it on the project list next time I get into my XV-01.

Interested you're going 30k and 1k oil. Keen to hear how you get on. Tarmac?

Thanks for the kind words . Based on your thread about setup I bought 1mill oil for the front. Meanwhile I have got the Carten M210R which fills my needs for a competent tarmac/summer postal racer in an excellent way. The XV-01 will then be an allround runner for the rest of the year. Since I run it on snow I think the 1mill oil will be too stiff (the temps are low), so I  try to go with what Nicadraus is running. The 900 oil which I assume are in the diffs now is giving way too much wheelspin on the inner wheel,  so I need to try something else.

I think in the front of my XV-01 I have 20k, something around about 5k in the rear. When I went from lighter oil to 20k in the front I was very pleased with the change. Much more controllable with my brushless power but still loads of fun. It's a while ago but I recall more controllable oversteer replacing a rather tail-happy character. Rear, no real data points. I think the only place I've used really heavy oil (500k) is in my DT-03 where the diff isn't properly sealed so I was trying to prevent leakage. I suspect 1mil oil in performance terms must be very close to locked out? My TT-02SR came with a locked out front, but I haven't tried that chassis in different diff settings so can't comment. 

I'd be very interested to try XV-01s back to back with a variety of front diff tightnesses going from stock thru 20k to much stiffer. I think that'd be an education. 

NB. I don't know anything much about setting up RC cars!

I am on trial and error here as well. 1mill is certainly more or less locked. My Carten has a spool in the front and that is predictable and nice. The prize for it is not surpricingly understeer in the tightest corners. 

 

I welcome a fruitful discussion about experiences with our lovely XV-01 cars . 

 

Looking forward to see you back in the postal racing again, BTW.

I fabricated my own using 2.5mm CF. I made room to fit brushless motors and still included the wire holder. Because even the Tamiya will need shaving.

[Andreas W]

Thank you for the answer,  @Nicadraus. 

 

BTW is your super tidy wiring very inspiring . I try to do it as neat as you do every time.

Thats lovely neat cutting and finishing work.

You are a carbon cutting ninja! Wow your work is amazing. I have the same tools as you but could never hope to get that kind of finished product!

Yeah I was hoping there was some secret tool but I've got a Dremel too, so unfortunately it looks like it's something called talent, that Amazon doesn't sell!

[Willy iine]

@Nicadraus You the man!   Looks factory finish too.  Great job.

Hello, 

I also have an XV01 that I haven't started building. Am I right in saying that a carbon motor mount means that the justock G2.1 will fit? I have seen some on eBay for around £8

Also does that mean this would be a good combo for the XV01 (with some wire extensions?)

https://www.modelsport.co.uk/product/hobbywing-justock-combo-js4-g3s-esc-g21-135t-motor-1359802

I know there is a few threads but I have ended up a little confused!

 

[Andreas W]

I see I have deleted pics to free up capacity. I'll add them here. 

 

The combo is nice from a performance point of view. I also got a good price and gave it a go. If I was to do it again I would put in a motor with dual sensor ports, or at least the port facing upwards. I see the vurrent Justock handout spec has the sensor port there, while the G2.1 still has it where mine has it.

 

Then you need to position the motor like I did and file off a good chunk of the motor guard. I also used a 40cm sensor harness. 

[jbee-arr]

Thank you! That's really helpful. Good work.

I am not new to RC (built and raced in the late 90s!) but this would be my brushless system. 

The handout spec motor you described is a bit more pricey. Tbh I just want something about 3500kv to play around with. 

The Xr10 looked like an esc that would fit but I don't have to. I do like hobbywing.

Do you have any recommendations around £80-£120? Could be that esc with a different motor?

Sorry, I am a bit clueless!

[jbee-arr]

Or I was thinking of getting a super stock BZ and sticking brushed for now. Then I could run it with one of the many Hobbywing 1060s I have lying around! 

Any thoughts welcome!

[Andreas W]

Hobbywing 10bl60 has more or less the footprint of the XR10 Justock and should be a nice fit. Here in Norway Surpass Hobby Rocket is good value for the money.

It will get hot really fast. I had few SS motors and definitely it is not a motor to use it daily. You will be surprised how thin line is between "hot" and "too hot", which will permanently damage motor.

It is fun to run from time to time for few minutes, but nothing more*.

*If you live in cold area ( temperature not higher than 10C) with clean asphalt, it will be fine.

If you want to stay with brushed motor and do not want to run it on really huge track, Sport Tuned is absolutely enough to have a lot of fun. The best thing in XV-01 is handling, not pure speed in straight line.
