320 or Rotax and Position of firewall
Posted: Sun Feb 19, 2012 6:15 pm
Hi Bob,
I have read Darryl's message about moving the firewall depending on engine.
As you know I am a few months away from installing my firewall and would
love the option of a 320 now which could be changed out to a Rotax later to
meet the sport pilot category if needed. I am hopeful that the Canadian
rules will change a bit to allow for an easy transition from homebuilt to
sport pilot should we adopt that.
All in all, the positioning of the firewall will be an issue for me (3" back
or not) when I get there. Any thoughts on the best approach to take. I know
of at least one other builder in SW Ont who has a 320 hanging on his soon
to fly kit, and is planning at some point to move to a Rotax. He left is
firewall position unchanged.

Hi Tyler !
That's the great thing about the Rebel - you don't have to decide
on an engine until you are ready for one, and you can always change it !
You'll have a couple of years to shop for an engine while you are
building - and things might change by the time you are ready ...
who knows, maybe even a diesel, or electric !! ;-)
The original 80 hp. Rotax Rebel, on 1500 straight floats, could
get off the water in 6 seconds solo and light, and 34 seconds with
2 big guys and 3/4 tanks, and still climb at 400 fpm. My old Rebel,
with the (much heavier) 100 hp. O-235-C2C, on 1500 amphibs, could
get off in under 17 seconds - if I was solo and very light ....
Flying well with lower power (and much less weight) requires
finesse, but it is very satisfying - especially at the gas pumps !
Ask the guys who are flying Rotax Rebels now about flying through
the Rockies on 100 degree days .... ;-)
Last Ramble to the coast, I put $2,630 worth of 100 LL through
my 150 hp Lycoming O-320 - the 80 hp. Rotax Rebel used $880 worth
of mogas, and the 100 hp. Rotax Rebel still used under $1K.
My <next> Rebel will definitely be a 100 hp. Rotax 912, set up for
1500 amphibs..... :-) Should be fun, very safe, and also meet
the US Sport Pilot requirements - which we might get, someday,
in Canada !

madeTyler, I am in BC (Langley) and used to run a 150 hp O-320 in my amphib
Rebel. Worked good up to about 3000 ft lakes. But higher than that, you
really extended your take-off runs, especially on a hot day. In fact on a
hot day, glassy water, heavy load, you probably wouldn't get off. And of
course, your climb rate is really down at higher altitudes on hot days.
Could be a real issue if you need to clear trees or a rise coming out of a
high elevation lake.
I now run an O-360 (only 8 pounds more than a 320) in my Rebel, and it
reallya huge difference in performance. Also, found that this engine has better
fuel consumption than my 320. That is probably due primarily to having EI
in the new engine.
And for perspective, my old 320 Rebel was no slouch. Near sea level, I
could be off the water in 10 seconds when lightly loaded, and less than 30
seconds with a heavy load. It still out performed any Cessna floatplane.
But if you are talking about flying into small alpine lakes (which I
engineenjoy), that is a whole different story.
One of the local guys here running an Elite amphib, is just in the process
of switching out his 180 hp 360 for an O-375 (205 hp). This engine weighs
the same as a 360, but has a stroked crankshaft to get the extra
displacement and hp. If you want to run mogas in this one, you need to
select the lower compression pistons (195 hp).
As for fuel, I use mogas whenever I can. In winter, and on trips, I use
mostly 100LL. Most airports do not sell mogas. Both Superior and ECI
Tylermanufacturers approve mogas, but recommend 100LL for break-in and
occasional use afterwards.

Thanks Drew,
I was concerned about that as I live in BC and there are a lot of high
altitude lake I'd like to visit. I'm fine with the idea of a lycoming
it'sbut I'm concerned with all the talk I hear of 100LL becoming a soon to be
forgoten commodity. any thoughts? anyone?

Yes. Maybe. It Depends on your mission. If you're near sea level and
mostlynot too hot it's probably just fine. What gross weight are you planning?
I swapped out my 125HP lycoming for 160 hp because I felt I had
margional performance at gross weight on a hot day and I'm in southern
Ontario
600-100'ASL.
