Policar Lotus 72

Recommended Posts

Received mine in the post early this morning and just had to track test it after reading all the hype and yes what a very good slot car best F1 i have driven in ages , it is well planted straight out of the box and with the tyres it comes with really holds the track , looks are stunning and the body detail second to none , drivability is great the FF style motor is extremly fast obviously slightly tight but i have given it a light lube and after 30 laps around my track is running very nice indeed and that gear train works very well , only thing i may do is add a bit of weight up front other than that this is a very good car.

Hi Peter

 

I picked one up today too and gave it a good run. Mine also drove very well out of the box and was hard to stop driving once I had done a few laps.

 

I am thinking of doing a review with it and the Scalextric Tyrrell 002 that just came out. The new Scaleys are probably a little better finished and with good tyres drive similar. Scalextric have also included a deep guide like they were selling after market which is helping their latest cars when running non magnet. The guide may be set back a little too far in the Tyrrell's but they are very good all the same.

Hi Peter and Vinno.

 

I got mine yesterday too. Do not have a track so still to try but after your comments may pull out some of my Scaly track.

 

Must say I was not very impressed with car as racing machine first off but perhaps I should track test first. Front and rear tyres made no pretence of being round and front axle would barely turn. Also disappointed that no ali wheels on rear. Plastic wheels are push fit.

 

I have already had apart which is a bit tricky because of rear suspension. Putting back together was even harder. Suspension componets however are very flexiblible so no problem. Also fitted exhaust which came unfitted.

 

Agree gear train seems a bit stiff but as stated I am sure that will soon free up.

 

Looks wise car looks fabulous so will make collectors happy. I had fitted some Slot-it GP ali wheels and F22 GP tyres but will return to standard for trial.

 

I will return.

Hi Chas

 

I had similar issues to you although I didn't mind the plastic wheels as they appear to be typical Slot.it plastics so quite true. Mine is a bit dodgy around the exhaust but I will detail more about the car when I review it.

Interesting to know how people rate this car & livery combo...

IMHO, I'd have it in my top 10.

Stunning.

Hi Vinno.

 

Have noiw run my car on Scaly track. After free running in for 15 minutyes I carefully re-positioning tyres and got them fairly true loose fitted. Ran a drill through front axle and can now spin wheels a few turns. Agree exhaust could be a continuing problem as it keeps falling off engine mounted section. Would be tempted to glue on but that would probably affect ability to take body off. Another option may be to leave off but reluctant to do that at this early stage.

 

On track agree car performed quit well.but not much grip out of some corners. Cleaning tyres on sticky tape improved a bit but glueing and truing probably necessary. Will not do so until I have had a chance to run on wood track as I want close to OTB impression . Car certainly ran very smoothly with good acceleration and brakes so a promising start.

 

Certainly looks great on the track and has a solid feel when driven. Does not appear to have any magnet but at 48.6 grams it is certainly no heavy weight.

Hi Phil.

 

Yes I agree on F22's. As stated I did fit these with ali wheels but Peter and Vinno's comments convinced me to put back to standard.

 

Depending on how glueing and truing of original tyres go I will fit N22's to plastic wheels as that is our preference locally rather than F22's.

 

Weight and sloid feel of car is interesting as the average Tasman Cup car is between 50-60 grams.

Been running now for a couple of days and have fitted N22 1172,s on the rear wheels which are a perfect fit on the original wheels, mainly as the car is now bedded in nicely and running faster, found the F22 started to bobble , not had the front axle issue mine was free think i have to much sideways play in the front axle which i will deal with and no problems with the plastic wheels, i used dry lube on the gear train which is nicely settled in, still think the front end was a little light but have improved that with a small quantity of lead , i have ordered a set of the rear alloys they do just that i prefer alloy wheels with the grub screw fixing rather than push on.

Vinno and all, be interested in your thoughts of the rear suspension feels very fragile and a bit of a performance getting the chassis out through the plastic piping , and getting it back again , my personal opinion is this is going to be a problem if you remove the body from the chassis very much as you may do as there is a axle stop with a 2mm grub screw in it for adjusting the slack in the rear axle which i have just done , now fitted a little more lead up behind the front suspension each side and that has helped keep the nose down, replaced the braid for me to hard prefer a softer one, on the track very happy with the mods a very fast car and handles very well., did notice there are 2 holes underneath where you can put 2mm grub screws in, and 2 on top of the axle holders to adjust the front axle up and down but no screws, wonder if all the cars are like that.

Hi Peter. Yes removal and replacement of body was one of the things I commented on. Suspension bits as stated are very flexible but might break in time. You need three hands to put back together.

 

Agree all the holes you mention are unpopulated if that is the right term. Same occurs on many Slot-it cars. They are just an enhancement that can be used if rules allow. In our Group C for example being a standard class they are not but would be in unrestricted GT class.

 

On suspension must see if bottom section unclips from the bottom of body. At a glance it appears to be glued. Alternatively if you could put axle in later this would fix problem but there is provision for tighening likes of axle stopper from outside so that rules this out.

Hi Peter and Vinno.

 

Gave the rear tyres a little sand and tried again. It was a little improved with better traction than my Scaly Ferrari with Slot-it F22 tyres.

 

Getting rather excited about trying car on wood track. No suggestion of lightness in front/de-slotting Peter so.do not see why this should be a problem. Tracks here are very smooth 2 pot finish. What sort of surface did you run yours on?

Carrera Charles loads of traction with the rougher surface , have added grub screws to adjust the front axle and stopped nearly all of the front axle rock also added a couple of washers each side to cut down lateral movement now the front stays well planted weight is just right with the adjustments i have made so far. yes the bottom under section is firmly glued on mine as well, very impressed with the gear box this is now so quiet after dry lubing and the brakes are really impressive better than some of my S can's.

Hi guys

Here's`a link to some handy info:

http://www.policar.it/Download/FAQ_PDF_en/01-PolicarF1assembly.en.pdf

and there is a thread on SFI discussing the car and any problems encounted. Andy and Maurizio are contributing as well.

Thanks Lenny.

That explains it quite well, and should reduce the damage once I attempt this.

 

Been patiently awaiting my pre-ordered car to arrive...

Runs off, checks mail again, nope... :(

Mine finally arrived...

 

I must say, that whilst it looks great, and drives well enough with it's stock motor, I'm kind of disappointed in it.

 

I must of gotten a Friday / Monday car...

One of the front wings is broken (internally only thankfully)

One of the spacers has a slot in it (C shaped), and only just doesn't fall off of the shaft

One of my front screws was an incorrect type, and jammed into the chassis

3 out of 4 tyres were not fitted to the rim properly, and as such, are now mal-formed

 

 

Also, it's definitely going to be a pain to gear these correctly for slower motors.

To work out the gearing, I built this chart Red writing is parts that don't exist yet, and Green writing is the stock parts.

Also, if they had just made the exhaust 'extensions' go towards the front of the car further, the whole thing would be SOOO much easier to disassemble / re-assemble.

I haven't got one yet, but agree that these cars look fantastic from the pics above.

 

I'm more interested in performance though. Do any clubs plan to race these? I'd be interested in how these cars hold up when the inevitable wheel to wheel contact causes cars to hit barriers.

 

The gearing assembly looks prone to problems if the rear axle takes a shunt. Also, how well will the front axle assembly hold up?

 

I've raced the Ninco F1's & performance is quite good. The simple inline gearing is fairly robust and the fronts have some "flex" to absorb impacts

 

Interested in any feedback

Hi Rusty sorry to here about your car , and interested in what you have there about gearing i think the motor is about 24,700 performance wise which is pretty quick i have SRP 25's in FF form and it leaves them well behind but what makes the performance really outstanding is the brakes never driven a FF can size powered car this good before, i think there are mods to come for the bodywork , i saw something from Rowlands on Slotforum about this , my second car is fitted with the alloys on the rear they do and it is a bit easier taking the wheels of to get the chasis out of that suspension, try Slot it N22's 1172 on the rear found they are better, would like a set of urethanes myself if Syd is reading this

I fitted MJK pro slot 21x11's to mine. Pretty good fit and they don't look out of place.

Even With the 14k bwa in it, boy oh boy does it have brakes, and is surprisingly quick lap time wise arround my small track.

That said, you are definitely hitting the rev limiter very early.

 

As for the gearing, Unfortunately, the pinion is a different size and pitch, so replacement pinions are out of the question.

Crowns ate a specialist item, and I don't think policar have released the axles, so gearing is stock or stock.

Top Slots and trains over web site over here have the spare axles along with other spares rusty, if you have a problem getting them PM me and i'll get them for you they are 16 and 18 tooth and the standard one is 17 in the car.

Hi SR.

 

One of AUSLOT's sponsors - Slotraceshop - also has them in stock. 16, 17 and 18 tooth I think. About $10NZ if memory serves me right

 

I am surprised you would want one until car well sorted though. I still have to run my car on decent wood track but it certainly flys on my short temporary Scaly track. Car is so light I would have thought it will pull well over a wide range of conditions.

 

Confirm great brakes too.

 

Wood track I am likely to try on has several very tight curves so should be a good test. Will report further ASAP.

We run BWA 14k motor's here in our classic F1's, and the gearing is just way too short for it.

Yes, I did notice that NZ has them, and I'm hoping a friend places an order there shortly, and I'll get my axle with it.
