I have two Racer resin cars (as opposed to Sideways DP and Gr. 5 cars). Seeing as I saw the Gunston Ferrari 350 CanAm race in real life and it was one of my first cars after my return to slots some 5 years ago, this one is unashamedly a shelf queen that sits proudly displayed on my slot car drawers.
Then more recently I got a Ferrari 512: I decided ahead of time this was to be a runner. Before running it I did some standard basic preparation: added urethanes, trued them a bit (just on the car, not on my Razor), lubed it etc. Turned out that it was an OK runner but not great. So I decided to make some more improvements:
* With body float and the pod slightly loosened, it was all but impossible to prevent the rear tyres from touching the body. With the wheels as fitted (significant hub sticking out from the wheel) there was pretty much no way I could move the wheels more inboard. So I fitted some CB Design hubless insert wheels and (GASP!) turned down the original inserts to fit the new wheels.
* Glued and trued tyres.
* Replaced the body screws with Ninco smooth shank body screws. Left them loose enough for decent body float.
* Backed off the pod screws a touch and taped the pod.
After all this I took the car to the track last night. I might have mentioned this before: I am somewhat OCD in this respect in that I take a lap timing sheet to the track pretty much every race night, complete with target lap times. Again a reminder: on Luf's Targa a lap time of anything under 8.5 seconds is decently quick, under 8 is very fast, lap record is just under 7.6.My target lap time for this car last night was 8.1 seconds. Actual lap: 8.234 seconds.
This is OK but really not startling. For comparison: as we were racing Targa cars last night I had a few Fly Classics there as well. Lap times for these cars:
* Fly 512S: 8.555
* Fly Porsche 917 Sandman livery: 8.240
* Fly Ford GT40 #60: 8.161
All of these Fly cars are similarly prepped: Urethanes glued and trued, solid front axle (if not fitted before), body float, guide shimmed (if required) to get the right front end ride height. That's about it. Due to the technical nature of the track, the lack of horsepower of the Fly cars is not such a big disadvantage. Generally they all handle incredibly well so I find them competitive with all but very well prepared and driven Slot.it and NSR cars.
Other lap times last night for comparison:
* Fly Racing BMW M1 (with decent looking wheels and tyres, not the silly looking Fly Racing wheels!): 7.989
* NSR Porsche 917: 7.790
The Racer was clearly a lot quicker in a straight line than the Fly's but did not have the same level of grip. Maybe I have to do some more work to it!
But it sure is pretty!!!!
