KR> Jabiru engine location
Dan, I can't help you with that, but thanks for the general CG location points. Iv' been trying to find this in my info when I didn't get it off the KRnet. I still haven't found it. Interesting that you are putting a Jabiru on your KR, I just received a new crated 2200 that I canceled the order for as they could not deliver it when I needed it. It will not work on the Sport Hornet application I wanted it for so I now have a new engine to add to my collection of goodies that I don't need. I see why you didn't need this cowl as it sure won't work for the Jabiru application either. Anyone out there need a beautiful new 2200 Jabiru pusher engine. I'm not sure what the difference in a pusher and a tractor engine is but I think its accessories. la...@lebanair.com I thought dealing with Rotax was as bad as it gets but dealing with Jabiru Pacific isn't proving to be much better. Oh well it will cost him some sales as it has Rotax. -Original Message- From: krnet-boun...@mylist.net [mailto:krnet-boun...@mylist.net] On Behalf Of DAN INA GLANDT Sent: Saturday, May 01, 2010 5:16 PM To: kr...@mylist.net Subject: KR> Jabiru engine location HI, Would someone be willing to help verify a reasonable engine location for my KR2s for a Jabiru 2200.
