Being even older technology than the flat engines, the Gipsy needs a little more care if it is to reach TBO without problems. Some points to watch; none of them unique to the Gipsy, but all of them perhaps more critical if you ignore them:
Always pull through 4 compressions before start, checking for no hydraulicing, 4 good compressions, and the impulse mag click.
After start, warm it gently and thoroughly before roaring off into the blue.
On T/O, open the throttle gently, don't slam it open.
Dont wang the throttle shut at TOC, ease the power off gently instead.
Be 100% religious about rpm limits - NEVER exceed them especially in aerobatics where it is all too easy to do.
In aeros, be gentle in throttle handling - no slamming it open and shut.
Never shock-cool it.
Keep the oil tank regularly topped up. Too little oil and it'll get too hot to do a good job protecting the bearings.
Allow some running at idle RPM to even out temperatures before shutting it down.
Shut it down from idle with both mags 'off' and throttle wide open (to prevent running on).
Just treat it with care at all times and it won't let you down. None of this should be news to any pilot (except maybe the pulling through).
