I have a TD 049 that has the crankshaft modified. It is made to look like a HD crank but looks to just be a standard crank ground down on each side. Was this a common mod or just someone experimenting?

Below is a picture.

Looks like you may have the helicopter crank but there is one difference, the crankpin isn't drilled on yours. That shaft may be from a Jerobee Cox TD .049 car engine. Then again it could have been a home mod, a real good home mod.

Most likely a home mod then. The crank web is not as thick as the helicoper crank on the right.

It could be a Cox experiment. I have an .049 in my gallery with a very similar modification.

NO his also has counter ballancing as well as the side cuts so this was probably just an experiment.
