To the moderators. Not clear if this topic lies in this section. It is about cars at scale 1/43, the
bodies could be used for slot cars but it isn\'t about slot cars (there is an approach called magnetracing
which uses rc cars in a fashion that is a compromise between rc and slot).

Now let\'s restart the thread.

I was unaware of micro rc till Kyosho announced that was going to enter the slot world at scale 1/43. When saw the Dnano cars (Kyoshos\'s 1/43 rc cars)
I thought...men! Can this work? I imagine a realistic track like the tracks we have in slot cars but with rc cars.
I knew that people have said that racing in small tracks without a slot had been tried and failed, but then I thought if the cars are at 1/43 scale
and one used 1/32 lane width or even a bit larger then maybe it could work and we would have circuits that would fit on a 4\'x8\' table.

I became restless. I tried to know more about the dnano and was surprised to see that not much is known about them and the info about them is very small
compared with slot cars (our hobby is much more developed than the small scale rc, I then also understood the move from kyosho).

I had two desires, 1) a rally track, 2) a road circuit for Le Mans cars. It was clear to me that a rally track with cars sliding would be most likely too much wishful
thinking.

So I went to see what cars are available and there are some rally cars but not that many (only 3, Lancia integrale, Subaru and Mitsubishi Lancer and no rally liveries!!!).
For me the most beautifull would be the Porsche 917 (no running mate), Porsche 962 and Mazda 787. So I decided to get a Porsche 911 GT1!!
What is the logic? I love the classic 911 and thought this car would be a compromise between a rally car and a Porsche 962 so I could test both the rally and the Le Mans possibilities.

I started to get as much info on the dnanos as possible. I have NO experience with rc cars, when entering the dnano and a bit of the Mini Z world I realized
that the rc crowed is basically speed oriented, realism is just not there (our slot hobby is much more diversified than the rc one). I looked at various dnano racing
videos and was totally disappointed. You have tracks with 50cm width sometimes much more for cars 5cm wide and the cars are going ridiculously fast and they bang
against the edges. What I desired was not there, I looked and I looked and the only thing I saw similar is a video of some guys running quite badly in slot car track.

Now I could keep this narrative is the long mode but I am going to accelerate, next posts will give more info.

I bought the Porsche 911 GT1, Starter pack (basic transmitter, battery for car, charger),
Gyro (will talk about it in other posts) and ICS cable (I will talk about this also on other posts). The last two items are not essential on what I have done so far in the dnano project.

I used a 4\'x8\' wood sheet which I already had to do a simply circuit (I have routed on it a slot test track, so I am using the other side for the dnano). I painted the track with some outdoors black spray paint and used cork for the edges of the track.
Here is the track:

How does it run? The key point! I have just completed the track and after 10 minutes asked my daughter to film it. She said she would only filt two trials so here they are, the first slower and the second just a tad faster (I am a complete beginner). Further impressions on later posts.

Talking about F1, there is a japanese guy that did a F1 dnano (there is a rumor that Kyosho might do them). Here is the link to a photo:

Zook, the dnanos are very friendly to the scenery. First they are light, second scale speed is not that fast and finally their motor in the low range does not have a lot of strength (when I ran the car in my slot car track and the car touches the smallest rock of glued bush it just stops).

Today was the first day I ran consistently without touching the borders at all (I have to say that it is a joy to put the dnano on the track and go for a spin).

I should update here my dnano project, a new track is being built, see below.

The dnanos have shown themselves to be fantastic and definitely work at scale dimensions. These are now not first impressions but reality. Some elements are essential in the design of the track. one of them is the use of white line and then a space before the borders. Without that one would be banging on the borders a lot which is a turn off.

Hi rallyP,
I love your track, awesome! I think with the painted MDF it doesn't look synthetic like most tracks do in micro R/C world. What paint did you use anyway? Could you try the track with your HPI RS32? Have you driven it a lot?
I like the RS32 idea a lot: all my slotbody's could fit!
Have been a while since I checked for updates here.
Grtz,
HaCo

Haco,

I knew that you would enjoy it. The dnanos end up being excellent. I hope it is a matter of time till become a prevalent force.
The issue for them now is that the general RC crowd does not really fully appreciate its potential which is of realistic racing that can be done at home.
The crowd that could appreciate this is the slot car crowd, but cultural or financial reasons are building a wall between the two hobbies. I think most slot car racers are not aware of the potential of the dnanos.

About the HPI 1/32 cars. I have tried them less and for me the jury is still out on them. They have for me two main issues: the battery life. They last 12-18 minutes. You can not replace the battery you have to charge them in the car (this is an incredible bad design, but maybe traditional Rc is used to this). To me this is a killer (the dnano battery lasts ... a lot, I do not even know If I have it charged it never ends in one section, probably last over an hour and there are higher capacity batteries available. I am wondering changing the chassis a bit to be able to remove the batteries at will. The other issue is I think a 1/32 RC car needs a bigger track. A track that looks fine for a 1/32 slot car will look small to the 1/32 RC car.

The good things about the HPI car are the motor, it is much stronger, so you can have hillclimbs, the motor has more brakes and the car is very stable on straights (no need for gyro). With respect to brakes the dnano is the opposite. I think both are extreme. The dnanos out of the box are a bit better than the HPI on curves, but I think that if one could take a away a bit of the brakes from the HPI car (maybe the gear mesh is just too tight, I have not looked into it) they will probably handle also very well on the tight curves.

About fitting, there will be only a few bodies you can fit on the chassis (check the wheelbase, very few if any rally cars before 1986).

About rallying: the dnanos will not work as rally cars in my opinion, but the HPI might.

RallyP thanks for introducing this dNano concept.

I agree with you that there is a ton of potential for these with the Slot Car community. My attraction to slot cars has always been because of the ability to scratch build life-like models (both cars and tracks) and to scale down realism - speed has never been my first love. In fact I hated it back in the Sixties (showing my age) when everybody started racing those slick-tyred speed machines on commercial tracks here in Australia.

I've always looked forward to the day when you could build and race scale models on tables without the need for slots. While slots have been necessary, I reckon they are a bit like trainer wheels on a bicycle! (Sorry for sounding like a heretic).

Bring on this concept I say! Give us scale realism and true driving realism - let us choose best lines (not the slots!). I wonder how hard it would to cannabalise an Airfix body into a dNano chassis?

? Maybe an old Airfix Mini?

Keep up the good work RallyP! By the way, how hard is it to learn to drive one of these things? I wonder if anyone's thought of fitting one of those mini-cameras on the front and driving using a screen!

Regards, Ron

Thank you. It takes some time to know how to drive it, but that is a good sign (I had never used a rc car before starting the thread and now I can drive the dnano well enough for realistic tracks). What took me sometime was to set the transmitter to brake in a way that I am used to in slots. If you start with a track that is 30cm wide (my track has 20cm+3cm width) you should be able do well very fast, then shrink the width.

Hey guys, sorry for not following up.
The forum doesn't notify me of thread updates (although) I am subscribed. So until now I decided to check out the threads I have posted before.

About the viedo, I will see what I can do in the upcoming weeks.

Rallyp are you still playing w the dnanos? Do you drive slots anymore?
I did read you post about slot cars having a plus of being all diferent. But I wonder what is you favorite at the moment and why?

You also mentioned the your track is 20cm plus 3. Does the mean 1.5cm on each side of the white line?

I have to say that you dnano track is beautiful. I wish I could come race with you sometime.
