What are the perceived problems with a wheel pilot ?
We have one on Raven that does the job nicely. I'd prefer it to be a tad quieter but it's not exactly horrendously noisy. We do have problem with belt slippage but this is caused by a worn wheel (pilot wheel that is) which is out of production and no longer supported.
This thing is fifteen years old and Ok it's ready for the heave ho but it does steer a most satisfactory course. Yaw is no great problem with it.
I doubt I would ever install another one if only because of the exposure to the elements but I'd rather than a wheel pilot than nothing at all even if it was only used when under power.
If I had my choice I'd also have a wind vane.
