I like it say 1200 -1500 throw away quick change engines.
Would increase units sold (bring down unit cost) and reduce many other maintenance costs.
What's a overhaul/new 172 motor with all fruit cost these days? $40,000+? What ever it is it is redickyouless!
If they were $15,000 for a rubbish bin job after 1,500 hrs/15 years it is $10 bucks an hour or $1,000 a year.
