RE: FADAC speed low indication
I know this is an old thread and out of date, but just wished to report that the Merlin 90 is still operating faultlessly and driving my Sprint around with great authority, if the new ones are better it looks like I may have to invest in another.
The old covering started to look a bit dated and it was that horrible to see against UK sky's Navy scheme, so it got a make over.
