[rebel-builders] Rebel- CONT. IO-240 MOTOR MOUNT

Bob Patterson · Post by **Bob Patterson** » Sun Feb 19, 2012 5:07 pm

Hi Cris !

Will the O-200 even FIT on the mount for the IO-240 ???
I'd be surprised, but maayyyyyybeeee.....

If it does, you have NO worry about the O-200 being too
light !! The Rebel worked nicely with the Rotax 912, which
weighed 128 lb - - HALF what the O-200 weighs, so there's
no problem with C of G. You could/should leave your battery on
the firewall, especially if you use a small Odyssey battery...
shorter wires, less weight, and simpler wiring. You don't need
a sealed box for those batteries - I've seen nice ones made
of Lexan (makes inspection easy !) . :-)

Sorry Drew, but DON"T EVEN THINK ABOUT building a
Rebel without the rear floor ! It makes the lower fuselage
into a box beam that more than DOUBLES its strength !
This has been proven by calculation AND in practice !

Hi Bob, Yes, I am sure the 0-200 will fit on the 240 mount. I have been told by Cont. mechanics that the IO-240 is basically an 0-200 with Cont. 360 Cylinders. But I am not positive of that. I have also been talking with "Jeff" at MAM and have given him the dimensions for the 0-200 engine mounting and he concludes that the 240 mount is exactly the same.
Bob Patterson, my friend, You have suggested the Rotax 912 engine many, many, many times. As much as I like the power to weight ratio of the Rotax, I refuse to seriously consider this engine UNTIL local airports start selling unleaded fuel at the "airport". "Right now" in the Southeastern States, the only fuel one can purchase at the airport is 100LL.. I cant see running 10 miles into town for car gas that is probably contaminated with ethanol.
My two cents, Cris

Hi Cris !

I know there are economics involved - and that's the real reason.
Didn't mean to nag !

We flew our 912 powered Rebel all over North America for 10 years
- and I <NEVER> "ran into town to buy car gas " !! I don't think
that's fair to the FBO's .... and besides, I'm lazy ! ;-)
We loved flying down to Florida, with stops in South Carolina
and Georgia, and out to Oshkosh, and all the way to the West coast,
and back through Quebec, and out to the East coast ....
It ran just fine on 100 LL, for 50 or 60 hours at a time, on trips -
I just changed the oil at 25 hours, (just like a Continental)
instead of the 50 hours I could run with mogas. Running 100LL
didn't hurt the 912 - it's still flying, 18 years later, with compressions
the same as new, and never been opened up for service ! There
are a few with over 4,500 hours without overhaul !!

At home, I'd stop for gas for the car, on the way to the airport,
and fill up the cans for the Rebel at the same time - no big deal.
Someday - maybe sooner than folks expect - 100 LL will go away,
just like 80 did --- at least the Rotax guys can keep flying !!

Many people now try to use car gas in their 'aircraft'
engines, to save money -- and pay more for early overhauls....

Just my 1.5 cents US - the Canadian dollar is diving again ... :-)

Hope you get it flying sooooon ! :-) :-)

Hi Bob When I bought my kit the rear floor was an option that I paid extra
for. This leads me to believe the designer doesn't think it's neccessary
and my plane is 1650 gross not LSA. I don't doubt that the inner floor
makes the tailcone much stronger but I'm not sure there's inadaquate
strength without it.

Hi Drew !

I've been unable to find any price sheet that showed the
rear floor as an option, except on the ultralight version.
Of course, in the early days, there were several "options",
- like dual controls - that weren't realllllly optional. ;-)
(A bit like 'automatic transmission' in many cars ! :-) )
Maybe it was there at one point, but shouldn't have been ....

All A/B Rebel kits are currently shipped with the rear floor.

I can show you pictures of the damage that shows up, eventually,
even on the ultralight versions !!! Anyone who has doubts can
check with experienced builders like Steve Sloan as to whether the
rear floor is necessary or recommended. He has done the tests !

If your primary interest in the O-200 is the ability to run 100LL, then I'm
not sure you'll be much better off. The O-200 was designed for 80/87
unleaded, and is prone to fouling when burning 100LL. I haul auto gas to
the airport to burn in my O-200 powered '68H Cessna 150, and it is much
happier than when I have to use 100LL.

If you can get a used one cheap, the O-200 could be a good engine for an LSA
Rebel. Won't have the performance of the Rotax, but should be a lot cheaper.
I think the 912S is 95 hp continuous. Even the 80 hp version of the 912 has
79 hp continuous which is more than the 75 hp continuous of the O-200, if
you want to lean it. Of course, if you go up to 8000 feet in cruise, all
that doesn't matter.
