Welcome, Tony.
I own a KR2 which is complete and used to fly; I live in Paris, and you
are welcome to contact me off net.
With a KR, you can build as you go, since the raw materials you need to
start your project are fairly cheap (wood and foam).
As far as engines are concerned, Barry made a pretty good summary. I would
like to add that:
- A KR will fly nicely with as little power as 60 hp.
- You can either buy a certified engine (unnecessary luxury in my
opinion), or buy a non certified "professional" engine (a non certified
Rotax, for instance) or buy an automotive conversion, or make your own
automotive conversion.
(Barry, as far as VW engines are concerned, you don't have to check the
tappets if your VW is a Type 4. Actually, the Type 4 is very different
from all the previous VW versions; it does not crack easily, has hydraulic
lifters, etc., and is definitely a good option; although I doubt you can
get one easily in Europe.)
- If you don't want to start an engine project, and want to buy a ready
made engine, go Jabiru. Cheaper and not worse than the Rotax.
In general, with a KR2, everything comes down to effort versus money.

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.

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!
Regards,
Tony
