ProSlot motor mounting on Plafit
I am building a new Plafit PF1700KSLP chassis and will be using a Proslot PS4000 motor. This is what we use for club racing here. What is the best way
of mounting the motor on this chassis?
The motor is quite smaller that the Bison it is designed for, and will be off centre. I hope to get it as close to the center and as low as
possible.
One problem is that the motor mounts don't fit. We are waiting for some new ones that could be usable, but I think I will try to make my own.
The other problem is that the rear gear (44 teeth) will interfere with the chassis plate when I put the gear as close to the ball bearing as possible.
If I move the gear outside the plate, I also will have to move the motor 4-5mm more off centre.
Another solution is to reduce the size of the gears.
Does anyone have any ideas or pictures of a similar setup?
Except for this the PF1700KSLP seems very fine. The only thing that needs adjustment is the guide holder and of cause the height. Everything else
lines up very good. The price is also nice.

Hi there,
well we use the motorholder made by Jürgen Stüdemann aka. Felgendreher. This motorholder lowers the Proslot motor like if you would use a bison with
the original delivered holder. The only thing is, that you don't have a second holder to secure the motor from behind!
Concerning the 44 teeth gear. We never had the problem that the gear interfered with the chassis plate. I could be that you'll have to add a 2mm or
3mm spacer between the axel holder and the gear. But that's what we always do (nearly every day) and it works fine. Once you've fides the motor in
the holder and the holder is screwed on, you'll find the correct placement for you gear on the read axel.
check the link below. there you'll see pictures from martin bartelmes (developper of the SLP version of the Plafit S24 Chassis) who builds up a
chassis with bison motor
SLP Chassis pictures
so what are the negative points on the chassis? kinda curious to know 
cheers,
Mike

We use 27.5mm wheels, and that requires about 1mm spacer for 1mm ground clearence. Then I have almost, but not quite the clarence I need for the 44
teeth gear.
What is your wheel diameter?
I think it will be OK to use motor mount in just one end if it has two screews and is stiff enough.
I don't have any negative points on this chassis except the motor mount problem, but that will of cause be the case will any motor that the chassis
is not designed for. I like it

Hey there,
well at the Worlds last year we used the SLP-Chassis with the 44 theeth gear, but note that you can't use the original axel holders. You'll have to
buy other axel holders from Plafit. They have 4 different kinds. Then you can use the photoetched spacerplates to do fine tuning on the setup an you
can reach the 1mm clearance without getting problems. I raced the 27,5mm wheels but I had 1,1mm clearance at the front and 1,3mm clearance at the
back.
Little remark: you have to use higher axel holders in order to decrease the clearance! same principle for front and back.
you're right that chassis was developped for the bison motor that is used in the 3 SLP series: SLP, SLP Challenge and SLP Cup.
but for the so called "lady-shave" motors you can already get the motor holder including the counter-holder. Don't think it will fit the
Proslot-Motor!
cheers,
mike

Hi Mike,
You are right about the axle holders that come with the kit . . . not tall enough for the 1,0mm clearance specification . . . and even the tallest
fronts (7,0mm) and rears (14,3mm) still need to be shimmed. I thought I would speak to Mr. Ono of Plafit when I am at the DPM about adding
additional sizes to get us closer to our IMCA spec. You (and others) have probably built a lot more of these SLP chassis than I have . . . what
should the front and rear spacers measure?

Scale Racing America
p.s. I noticed that the clearance is down to 0,6mm for the F430 sprint races (only) at the 2008 IMCA Worlds. Good thing the track
is new . . . and flat!

Hi Guys,
the SLP chassis and the parts were developed for the SLP series as raced here in germany.
The 14,3 rear holders will give you you 1mm clearance with 27mm Wheels the front 7mm blocks will give you 1mm with 24mm wheels - SLP specs. We run
27,5 at Imca/EEC and should have about 0,8mm-1mm meaning that you need shims of about 0,25mm. Shims you need just incase you need to adjust the ride
height during the race, plafit has the quick fit shims that can be added or removed without having to take off the rear axle holders ... nice and
flexible the fronts.... we run 25,5 mm minimum if you mount the
stabilizer under the actual axle/bearing holders, you gain another millimeter...... and do not need shims.....need to play around with the shims or
without or just use bigger front tyres....

Hi.
Can anyone tell me where I can buy this motorholder made by Jürgen Stüdemann aka. Felgendreher. ??
So the "PF1708" does not fit the proslot motor?

This is what I ended up with. I used a Schoeler Pro Slot motor mount that is slighly modified to be able to lower the motor enought. In the rear end I
made a clamp of 1.5mm alu. Now the motor is fixed good in the correct position, low and almost in centre. It also uses two screews both on the motor
and to the bottom plate.
Spacers was not a problem. I made my own 1mm rear spacers and used the supplied plastic spacers in the front.
I think this is as good as it's get with a lady shaver motor

I was about to suggest the same. I have used the Schöler option a few times too.
FYI the holder comes in two sizes
LONG
and SHORT
I see you have the long version and that is why you have the Spur gear the wrong
way around. and the problem that the gear , if any bigger , will foul on the bottom
Plate. The short version moves the motor out further and eliminates the problem.
Cool thing about it is that you can choose the motor height your self....
IO now use the "Felgendreher " part but it is not adaptable and costs 3 x the Schöler.
Your Rear clamp is way cool!  Well done! I now have a part that is
similar to a motor holder, works well but is way too expensive

looks fine Bimmer
But I have noticed that modifying an original takes the same time as it takes to just make one from scratch from an Alu 'L'-profile. Usually on the
back I make something like the front, where my opening fits over all four sides over the endbell thingie

Fola, I used this motor holder from Schöler:
http://www.norsk-bilbaneforum.com/shop/index.php?main_page=product_info&cPath=2_18&products_id=216
It is specially made for the Pro Slot motor. This is what we use on our Schöler chassis here in Norway. We got it from a Norwegian web shop, but I do
not have the product name for it. Using this I can mount the motor with two screews. You just have to make the holes a bit lower to get the motor all
the way down.

2 screw motor mounting... never don that before.... but safe !
Cant find that holder in German Webshops, maybe coz no one runs the ps4000
motor here.....
They should still make a short version ;-)

Hmm Hmmm, this is my FIRST Plafit experience so... 
Nevertheless this is what I propose as an alternative to a "wild" motor mounting :
The pinion side is equipped with the Schoëler motor holder (short or long, I have to verify, but I think it's the short one...) with 2, yes Fola
read it TWO mounting screws. Next I will try an upgrade with a modified
new "Norvegian" Schoëler ProSlot motor holder, always with 2 holes for 2 screws 
On the opposite side, I'm using the machined holder supplied in the SLP Plafit kit, but modified and fitted with a piece of carbon as an adapter...
pfff 2 screws once more...
You can see how it looks with some pictures on http://picasaweb.google.fr/Philippe.Laudet/TechTips
Comments are welcome,
Kinds regards,
Philippe - Zmachine
be care... Alsdorf, here we come...

Looks good! Nice job with the rear motor mount
You have the short Schöler motor mount. The "Norwegian" 2-screw mount is the long type. Then you will have to turn the rear gear the other way
around and will have conflict with the bottom plate.
Of cause you can make new holes in the motor mount closer to the motor and convert it to a short type.
Another option is to change the bottom plate to the thinner version. The stock is 1.5mm, but you have a 1.3mm option. This should give enought
clearence for the gear whan you add 0.2mm extra shims.

Hi Guys,
just a question : could somebody from the scandinavian countries bring us some of these 2 holes motor mounts, no way to find it over here at our usual
suppliers. I would like to have 3 of them, and will pay for them at the Afsdrol race.
VBR

I am not going there, but I can try to get the product name for them so you can order them directly from Germany. You can also try to order some from
the web shop of Jostein Vandaas linked above. If the norwegian is hard for you then you can email him here:
http://home.online.no/~vandaas/epost.cfm
Are you going to use them on a Plafit of Schöler chassis? The are a direct fit on Schöler with 44/9 gear, but needs to be modified to fit Plafit.
They are also of the "long" type.

Bimmer, thanx for you interesting comments ! I simply ignored that a 1.3mm base was available by Plafit !
Raymond, I have bought such motor holders through Jostein in Oslo.
I will participate to the Liege Gr5 race on Saturday, I will bring one with me if you like...
Kind regards to all of you,
Philippe

For others, the 1.3mm base has the part# PF1701B and you can find it here:
http://www.plafit.de/index.php?uid=C7d482130c905572f6af1b1845ea6a637&go=ALL
I think the difference between the 1700 and 1701 base is that they added some extra mounting holes on the 1701 version. You can also get it in 1.3mm
alu, but we should be needing the low weight of the brass base plate.

I'm going, so if you order anything from the norwegian sites, just ask them to send it to me (Jostein knows how he kan find me) and I'll bring it to

Very nice! Is this the expensive rear holder you were refering too?
Where did you get the heat sink for the motor? Have you done any measurements to see what temperature difference you get? Did you ever have any
problems with the motor overheating? I quess lower temperature will increase the life span of the motor anyhow, and reduce the risk for race
incidents.

yes it is ..... and the set is very expensive (due to small quantities) , but very nice too !
The heat sink is from Jens... in Germany, have not taken measurements, that is a bit
too Tech-ie for me,
