Re: Electric Model A's
More than likely his wife could drive a stick and he was jealous
Yes learning to drive one should be a requirement for license

Re: what is this? mag drive?
It is an attempt at a side drive magneto
The gear is properly sized for a mag with 2:1 gear reduction or a governor
Most aircraft mags are 2:1 or crank speed.

Re: Donovan 4 Cylinder
Chris
The V4 classes are Vintage strictly meaning original blocks of pre 1935 manufacture
You can run the Donovan in the displacement classes but the architecture is a disadvantage

Re: Donovan 4 Cylinder
This was a couple years ago, "D" block and a Arnold Birner head a friend was making.
I did a build on another "D" block made for the Birner head, without intake ports or valve chambers.
