Hello to all, I present myself, my name is Antonio Beneytez and finishing of 

build a Zenair 601HD in Madrid Spain, after a lot to look for engine is 

almost resolved to mount a subaru Stratus 2000 and I would like to know if 

you have had some problem with this motor and as solving it. I would also 

like to know the benefits that he has the airplane with this motor like: 

consumptions, wheight, speeds stall and of cruise that distances it travels 

before the take off, etc.

That propeller is the most appropriate?

Is there some problem with the ignition?

If you consider some important fact I would also like to know it.

Thank you.

Antonio,

Some number of years ago the Stratus was very popular on this list, now 

everyone is looking at a Jabiru or Corvar. Myself I bought a a Stratus 

and am very happy with it. I have about 60 hours on my 601HD and have 

had no engine related problems. My point was I did not want another air 

cooled engine water cooling has several advantages that have been 

debated on this list in the past. The most important part of a reliable 

installation is a adequate cooling system. I my opinion the Zenith 

system with the "diaper" radiator on the bottom is marginal at best. 

Some have made it work well but I have heard of many that have had heat 

problems especially on hot days. My engine runs at 190 F on any day 

summer or winter, on a long climb out in the summer it might rise to 200 

until I level out. People on the ground comment on how quite the plane 

is. Unlike aircraft engines I have had in the past where 1 quart of oil 

every 10 hours is considered normal, I use about 1/2 a quart between oil 

changes of 50 hours. As far as specifics for my plane I use a Warp Drive 

prop and cruise of 75% power at 105 mph with a fuel burn of 5.6 gal/hr. 

My empty weight is 788 lb.( sorry everything is English measure) but I 

have a full IFR panel. I have heard of some problems with the ignition 

but I have not had any. Let me know if there is anything else you need 

to know. As for the most important item, cooling, I think if the engine 

is adequately cooled most problems don't happen.

Antonio,



I think it would be worth your time to read the list archives.  The list

is very small and everything has been talked about in great detail.

After getting the history then you may have specific questions.



A short list might be this;

- get the dual ignition

- make sure the upper right(?) engine mount is a newer design

- ask for a "short" starter so the throttle springs can be setup to

pull-"on"

- send the heads to RAM for upgrade (stepped valve guides)

- wire a redundant battery supply for the second ignition

- relieve the secondary ignition bracket of the sharp inside corners or

it may end up cracking

- setup the belt tension for 1/4" play at the prop tips when cold



- anything else?



- a 72" Warp Drive 3-blade square tip ground adjustable has worked well

for many people.  



- it consumes just under 4 gallons/hr at slow cruise, 5-6 at high cruise



- there are a lot flying and it has been a very reliable and economical

engine for most people.  I have been very happy with mine.
