Seems like there is a lot of noise in this thread with people not collecting
easily available data before their comments are posted.

Flaps up is the correct POH procedure for a short field takeoff in the later
model Bonanzas. Ten degrees of flap was used in early models, but does not
apply to the A36.

Four adults, moderate bags and full fuel is a normal (within limits) load
for an A36 Bonanza. This is a 6 passenger plane. Useful load by the book is
1560 pounds. Gross weight is 3600, typical empty weight slightly higher than
the book 2040, more common is 2200.

I looked up the airport 061 Cameron CA. It has a 4000 foot runway and is at
1287 feet. Google maps show long overruns which slope uphill.

I looked in my Bonanza's POH. My plane is a V35A and is similar but not the
same as the A36. The A36 has lower book numbers because they are computed at
an additional 200 pounds of gross weight. Norm Colvin (Bonanza guru) says
that with the same power and weights all Bonanzas will perform about the
same. The A36 often has the bigger IO-550 engine improving things. Using the
Beech tables and charts for my plane at 110 degrees F 3600 pounds and 2000
feet airport elevation I get a takeoff distance of 3500 feet to clear a 50
foot obstacle.

In short given the conditions and load I would have no qualms about
departing in a Bonanza from Cameron. My worst case numbers above show
substantial margins.
