Rats, I'm thinking electric gyros now.
Marko,
Electric instuments are noisy, unreliable and expensive.
An ordinary aircraft vac. pump can be modified to be driven by a 10mm
internal toothed timing belt by removing the shear coupling and adding two
push fit ball bearing races. The pump can be driven at a lower speed than in
the Lycoming by selecting the appropriate cogs and driving from the water
pump pulley. For aircraft use smaller a smaller crank pulley than standard.
