And what are you basing your above statement on?
As has already been pointed out to you, Bostig primarily develops and sells
the kit/package, EXCEPT the engine. Read their site. Use simple factual information
rather than "thoughts", "presumptions".

It's probably THE most beautiful aspect to the Bostig development ....
the easily-replaceable-world-motor. And $300.00 is a not uncommon
engine replacement cost for these.
