Subject: | What will you replace your rotax 447 with? |
I have 70 hours on my 447 after 3 months of flying and I am starting to think ahead.
Instead of rebuilding the rotax wouldnt it be wiser to buy a current production
engine?
I spent sometime on jack b harts page and he it looks like he is a big fan of the
mz4.
It seems our current options are the mz34, victor1+, maybe mz201, h-33, and kawasaki
440. Is there any I am missing? What your opinions on what or if to replace
the 447 with?

Well the price of a 447 rebuild, especially if you have the mandatory crank
replacement, puts you well on the way towards a new engine.
The new Hirth would be way up on my list. The 2702 is the closest
replacement for the 447. Also very interesting is the F-23 opposed cylinder
unit. Weighs a lot less and has more HP than the 447.
At the rate I am putting hours on my 447 it will probably last me the rest
of my life. :( At the very least, it should last until there is a good
electric alternative. With 5 Gal. of fuel providing 1.5 hours of flight for
a weight of 130# the Rotax is a pretty good setup. But with a 10# motor, how
much battery weight does it take to fly 1.5 hours? Not there yet, but
hopefully in the next few years...
On the other hand, if your 447 is performing well and can be rebuilt for a
reasonable price, you might be able to get another service cycle out of it.
By then, who knows what will be available?
A tough decision that only you can make when it comes to
reliability/convenience/dollars, etc.

It really seems like electric is a long ways away. Even when it becomes possible
in a part 103 application I assume it will cost a fortune. Interestingly enough,
I met a fellow a few months ago that designed his own plane and is going
through the process of getting his plane certified (through the faa?). He said
it would be an electric hybrid 5 passanger plane. It would have a very small
deisel generator onboard that would contine to charge its batteries in flight.
I forget what the performance specs were but they pretty impressive. Anyways,
i doubt such an idea could be impletmented in a part 103 plane, but who knows!!!
