Welcome Tony, In my opinion the KR2S is a great choice.
Engines (the controversial subject) a.. Certified engines like the O-200, etc are too expensive and a bit fuel hungry b.. Corvair engines are an auto engine and unless you are in the US may be a bit hard to get parts for. Also as I understand it, the crank shaft lateral thrust bearing is on the center journal which could cause problems for the cracking of cranks (someone please correct me if I'm wrong where the thrust bearing is). c.. VW conversions, yes another auto engine but they have been in aircraft for ever. The problem here is that they are heavy for the horse power they deliver. People try squeeze more HP out of them and then they become unreliable. You have to check the tappets regularly. d.. Jabiru engines are light, designed for aircraft, reliable and fuel efficient, but you have to check the tappets regularly and can only use a timber prop. e.. Rotax 4 stroke engines (don't know much about the Rotax 2 stroke engines) are light, designed for aircraft, reliable and fuel efficient. They have water cooled heads, hydraulic tappets, you can use an in-flight adjustable prop (if you want). Very user friendly in that you don't have do much on them, except turn the key and fly, but a bit expensive. Best Horse Power for weight against MY dollars is the Jabiru. The above are only my opinions and will no doubt cause some heated discussion :-) This was the process led me to deciding on a Jabiru. regards Barry Kruyssen Cairns, Australia RAA 19-3873 k...@bigpond.com http://www.users.bigpond.com/kr2/kr2.htm ----- Original Message ----- From: Antoine F8CKH To: kr...@mylist.net Sent: Friday, September 09, 2005 6:44 AM Subject: KR> Hi from a new comer / prospective builder in Europe Dear all, My name's Tony, I'm a 24 year old Flight / Attendant for a british airline. I've been flying since 3 years now (I've got my PPL in France) and I would like to move on to something else: build my own aircraft and enjoy flying that way. As my dad had begun a Cozy several years ago, I was already pretty much aware about what is an experimental aircraft but now it's time to go for my own project. I'm ready to spend hours in my workshop and now here are some questions about a KR2S project: - I didn't have a look yet at the plans themselves but I'd like to know how is the building process divided into parts. Whilst I'm looking at the different groups (1, 2, ...) of raw materials, I guess everything has to be built from "'scratch"? (apart from those molded parts) - What would you think of mounting a Rotax 912 (100 HP) on the aircraft? Apparently, the Rotax has a gross weight lesser than a Continental O - 200. Anyway, This was just a quick introduction and I hope to hear from you soon, guys!
