Here's one way of converting a 36D motor bracket into a Falcon motor (Falcon II or TSR D3) bracket. This modification allows one to use an alternate Falcon motor instead of a stock 36D motor for the '46-'79 NASCAR class. I used this technique to modify my stock 36D NASCAR in order to use a Falcon type motor. Falcon motor bracket on left and 36D bracket on right Flatten Falcon motor bracket. Cut off sides of bracket to fit into existing 36D bracket. The "Nibbler" makes cutting the brass easy. Use felt pen to mark location of Falcon motor mounting holes. A round file was used to make slots in bracket. You can solder the Falcon motor bracket to the existing 36D bracket. Or, if you do not solder the brackets together, you can use motor screws to secure both the new bracket and motor. Remove the falcon bracket and you can again use a 36D motor. Keith

The above modification can be done to an existing 36D NASCAR. I made the mod on my 36D NASCAR and used a Falcon II motor for testing. I mounted the Falcon motor on the same axis as the 36D motor and therefore the CG (center of gravity) was high as the Falcon motor was about 1/8" track clearance. This higher CG did not seem to affect the handling of the car since my 36D NASCAR is heavy (225 Grams).

Good news: Buena Park Raceway now carries a "tall" motor bracket for the Falcon motor which has the motor mount holes drilled. Keith

Keith, have you tried lowering the adapter plate and running it in hypoid configuration? Jim

Keith, have you tried lowering the adapter plate and running it in hypoid configuration? Jim Jim, I haven't tried a hypoid configuration on this particular setup. In general, I don't favor using hypoid myself since the lower CG on these cars is not as significant as say a lightweight retro car. Theoretically a hypoid setup with lower CG should be an improvement over the regular motor mount, but there's a trade off as far as gear mesh efficiency is concerned. The Falcon II, Slick 7 mini brute motors have low torque and the gear mesh is important. Also, these lighter weight motors (vs. 36D) don't have as much affect on these heavier cars. As far as hypoid vs. non-hypoid I always remember asking Duran Trujillo if he uses a hypoid setup on his retro cars. He answered that he does not use hypoid. He indicated that the hypoid setup was not an improvement on the regular motor setup which has a more efficient gear mesh. Hypoid or not, it's your choice. Probably not much difference either way when done correctly. The hypoid setup does require a very good gear mesh to work properly. Keith
