Was not going to get this new car yet was going to wait for a decalled version, but amongst the test cars was a painted yellow one which i rather liked and i knew i had some decals to make it look a lot better than a yellow slab.

On arrival it looked rather good and after taking out the magnet and inserting the front grub screws i gave it a warm up on the track, the rear tyres are treaded Supergrips and after a bit of running came in well as far as grip was concerned, now the motor is the 21-5 k evo which has a good turn of speed as it ran in, now over here this motor has caused a bit of interest as all the motor nerds reckon it,s 21-9 in the k range , i don;t know aBout that but it,s quicker than my older NSR motors in that form, just had to paint that driver.

On the track it,s lively needs weight and softer braids in my opinion , front lifts when applying full power the motors run in and the rears have gripped up, and all is smooth so definitly weight the front, enjoyed the car great slot car , but i knew i could do better as i had the parts to do so.

First was fit the NSR wood guide and softer braids, , motor wise used the Pirana 25 K ballrace motor which i am using a lot now , give loads of control smooth and very quick in this form, as i was using a ballrace motor only right i ballraced the rear axle , then some weight note the picture , decided to keep standard gearing, all the wheels and the original rear tyres as they were operating very well on Carrera track.

Back on the track and yep lap times were soon in the modified Thunderslot range , can see this car being a very good stable mate for a mod Thunderslot in the same configuration which mine now are except for one Lola Spyder which is basically now the slowest of this fleet of cars , next for mods, i have no where to race so it,s me against the clock with each class of car i have and during the pandemick i have really gone to town in my quest for fast great handling cars.

Few pictures.

Yes i always weight the front of the chassis as near to the front axle if possible in that chassis the recess behind the guide post is the best spot i,ve found , apart from that i,ve only weighted the pod in front of the motor .

Have found the tyres that come with it i beleive they are supergrips are ok but have changed to Ultragrips for wood , but the Supergrips seem great on plastic track like Policar or Carrera.

got mine tuned, is tailey compared to my mclaren and 908.  got most of the pod covered in lead.  Wonder if i should put some weight up near the guide ?

They're only a short wheelbase so will be 'taily', try moving the weight from the pod to the area inside of sills on the chassis.

they are quite a big car and very wide.  Got t-slot and 908 running good.  ive got weight in pod and some on the side, i don't really want to load it up with tonnes of weight but maybe ill have to play around a bit with weight setup

Wheelbase is the same, similar or extremely close on all three cars.  The differences are the width:   
measurements taken from my 3 all which are modified from the original and taken at the maximum from the side of the tire, to the other side.  
917 62.25mm  this is where the tire will rub the fender on my car 

908   63 mm as wide as I could get set at 62 due to proxy rule 

917-10 WIDE  64mm  limited by a proxy rule
