R680 Powered Beech 18

Does anyone have time in a R680 powered Beech 18? If so, what sort of
performance numbers are they capable of and are they reasonably safe on one
engine?

It must be extremely marginal on one engine with any kind of load. A Bamboo
Bomber won't hardly stay up with one running.

Isn't the "Bamboo Bomber" the nickname given the Cessna T50 Bobcat? I never
heard it used to describe a Beech 18.

Are you sure that it isn't a Jacobs-powered MOdel 18? I used to know a
man who had one (late 1970s) in CA. He used to take it to all the
fly-ins. It had smaller fins/rudders than the C/D/H-18 and bumped cowls.

That seems way underpowered for Beech-18. Fully loaded, the R-985 Beech-18 is
interesting single engine.

The Bamboo Bomber is A Cessna T50 or UC78. I did not refer to a Twin Beech
as a Bamboo Bomber. Simply stated a BB with similar engines has trouble
staying in the air on one engine even though it is a considerably smaller
airplane.

Sorry. I missed the part in your original post where you mentioned that the
Beech 18 "is a considerably smaller airplane". Or where you pointed out
that the two aircraft have similar engines. I guess you wrote those bits in
invisible ink.

The Beech 18/ C-45/ AT-11 were the same 'basic' airplane.

The first 40 built in the late 30's had 330 HP Jacobs with P & W 450
HP engines in the Military C-45/AT-11/etc.

I got some time in the C-45.with the 450 HP P & W engines.

Your R680 is the 300 HP Lycoming (Model HRE). Didn't find any mention
of this engine in the early D-18's but may have been a proto or first
engine before they went to the 330 Jake?

C-45 bird flew ok. Would fly on one engine after airborne an cleaned
up . Not any super performance of course. Max altitude on SE was
probably 5K or so (from memory).

Much better performer than 'Bobcat' on SE.

Was a good little twin for its era.

Some are still flying today.

On the Lycoming and Jacobs. Don't have the weight on these birds but
were probably much lighter than the military versions (Military always
added a lot o 'junk' and gross went up). Even with a light civilian
bird, I'd guess the Lycoming was a little short on power so they went
to the Jacobs?

Enough. Others may have some more first hand experience on the Twin
Beach and knowledge of very early versions?

It was clear to me. Anyone else have a problem with it?

Robert,

Where in the world have you found an R-680 powered Twin Beech? That
has got to be an incredibly rare beast. I thought only one or two of
the very first ones had other than Pratt and Whiskey R-985s. The
early ones were much lighter, but, still, the performance had to be
marginal at best.

Have you ben able to get your hands on a manual for the R-680 powered
model? Given that it would have been written in the 1930s when most
manuals were pretty basic, I'd be curious what it reported about
performance. Does the airplane even have feathering props? What is
the serial number of this airplane?

All the best,
Rick
