From: "Keith84" 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?

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. Stuart -----Original Message----- From: owner-kolb-list-server@matronics.com [mailto:owner-kolb-list-server@matronics.com] On Behalf Of Keith84 Sent: Friday, October 16, 2015 1:04 PM Subject: Kolb-List: What will you replace your rotax 447 with?

From: "Keith84" 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!!! -------- 98' Kolb FireFly Read this topic online here: http://forums.matronics.com/viewtopic.php?p=448026#448026 ------------------------------------------------------------------------------------- Other Matronics Email List Services ------------------------------------------------------------------------------------- Post A New Message kolb-list@matronics.com UN/SUBSCRIBE http://www.matronics.com/subscription List FAQ http://www.matronics.com/FAQ/Kolb-List.htm Web Forum Interface To Lists http://forums.matronics.com Matronics List Wiki http://wiki.matronics.com Full Archive Search Engine http://www.matronics.com/search 7-Day List Browse http://www.matronics.com/browse/kolb-list Browse Digests http://www.matronics.com/digest/kolb-list Browse Other Lists http://www.matronics.com/browse Live Online Chat! http://www.matronics.com/chat Archive Downloading http://www.matronics.com/archives Photo Share http://www.matronics.com/photoshare Other Email Lists http://www.matronics.com/emaillists Contributions http://www.matronics.com/contribution ------------------------------------------------------------------------------------- These Email List Services are sponsored solely by Matronics and through the generous Contributions of its members.
