Tell another owner
Your model needs 20 more owners.
This is the one thing you can do that money cannot. There are 216 Bellanca 7KCABs on the registry and every one of them wears out the same parts in roughly the same order. The page only starts answering questions when enough of those owners are writing things down.
Nobody has posted a Bellanca 7KCAB squawk yet. Post the first one and it shows up here immediately — every owner who lands on this page after you sees it, and the ones who recognize it are the people worth comparing notes with. Here is what this page becomes.
Here is something to send
Rewrite it in your own words. A note that sounds like you beats a referral link every time, and the people you fly with can tell the difference.
What you get for it
Better answers about your own airplane
This is the real one. Every 7KCAB owner you bring in makes the page you care about more accurate. You are not doing us a favor — you are filling in your own picture.
The model opens for everybody flying one
Including the owner three states away you will never meet, who is about to find the same thing on his airplane that you found on yours. That is the entire point of the exercise.
Your name on the model page, if you want it
The owners who started the record for a model get listed as founding reporters. Entirely optional, and off by default — some people would rather not be named, and that is the whole ethic of this thing.
Nineteen dollars is not worth gaming, and paying people to recommend something turns a favor between owners into a transaction. If you tell somebody about this, we would rather it be because it is useful.
