Some time ago, Scott bought a finished Toyota GT-One from me. His plan was to convert a Scholer i55-1360 chassis to fit a Toyota. Unfortunately, the Toyotas wheelbase was a bit too long for the chassis so some chassis modifications were in order. Scott is relatively new to the hobby so I volunteered to help with the conversion and some tuning. Below is a summary of the process
  • Remove existing front pan and hardware
  • Fabricate and attach new front pan. Notice that I shimmed the V section holding the front pan to compensate for difference in thickness of the center section and the .062 inch front pan. Proper shimming ensures that the front pan and center section create a flush surface on the bottom of the chassis.
  • Check all bolts for tightness
  • Adjust front and rear wheel height to .055 inches
  • Adjust flag depth so that wheels just touch the surface of the tech block
  • Check side pans. These should move freely with or without the body attached. I found that there was some interference and took a bit of material off of the pans.
  • Adjust gear mesh
  • Attach body with mounting bolts
  • Test
In testing the car exhibited a lot of chatter upon hard acceleration. I determined that some additional plastic needed to be cut away to insure that the wheels did not touch the body under any circumstance.

During initial testing Scotts Falcon 7 motor gave out. I replaced the Falcon with an old Hawk 7 that I had. That particular Hawk was quick. The problem with it was that it would not attain peak RPM for several laps. I will inform Scott that he should replace the motor. If he desires, I have several spare Falcon 7 motors for him to choose from (I replaced all of my Falcon 7 motors with Hawk 7s). The Hawks are about .1 or more seconds per lap quicker than the Falcons on my track with relatively heavy hard body cars.

The chassis set up is almost identical to my Toyota GT-One. The car handles as well as mine and in testing turned a 4.83 second lap. With a stronger motor, it could challenge the fast lap record or 4.713 seconds. Below are a few images of the finished product.

Thanks Don,
Since the image was snapped I added some wheel inserts. Watch for the debut of this car in an upcoming race. I think the race at Electron Raceway will be on 4/25. I post the results of all races at Electron here http://slotblog.net/...n-race-reports/ and for our sister track STR here http://slotblog.net/...r-race-reports/
