Re: Victors or Jaguars

We fried one or two drivetrain Jags last year, due to swarf that got inside them. They were mounted horizontally; i.e., flat side down. We could easily see the burnt mark on their circuit cards near where swarf had shorted two pins on one of the ICs.

This year, we used six Jags (drivetrain and shooter) and mounted them all vertically. This seems to have helped; no failures. Possibly the swarf (if any got inside) settled to the edge of the plastic case, away from the circuit card.

Anyway, I like Jags for their linear response and CAN interface. Victors are nice for their smaller footprint, and they might be more robust against swarf -- because they have fans.

I believe in intuition and inspiration. Imagination is more important than knowledge. For knowledge is limited, whereas imagination embraces the entire world, stimulating progress, giving birth to evolution. It is, strictly speaking, a real factor in scientific research.
