Default Re: Timing the model a....

I may be misunderstanding some of the suggestions but you would be lucky to get close to TDC by watching the piston through the spark plug hole. It can however assist you in knowing you are close to finding the indent in the timing gear. There is approximately a 15 degree range of crankshaft rotation where the piston will be within .010" of TDC.

Assuming the car is currently running you can use the location of the distributor rotor to know when you are getting close as previously suggested. My link below will offer more info which may be helpful.
