Wife and I used to operate out of a private
grass strip. Lighter weight Longez (847# dry – actual weight, 1400# max
gross) than the L-235 with the same Lyc O-235-C2C, 118 hp.
3300 foot very well maintained grass strip (X09)
is SCARY with 2 people and 40 gallons of fuel (52 gallon capacity). And this
was a well maintained runway, crowned, cut short, dry, hard – all the
good attributes. Admittedly it was heavy on departure but if you want to go a
long way, you fly with lots of fuel.
We sold that property and moved to where the
runway is paved.

Thanks for sharing the
info. All very good information.
Swaid asked about
320's in 235 airframes also. The 320 in the 235 airframe here may not be
a good one to use as the engine is not stock and is underpropped. It gets
2550 RPM static and on takeoff with the fixed pitch prop at field elevation of
1330. Climb is about 1300+ ft per min solo with an aircraft
weight of 1012 lbs. empty. I weigh 170 lbs.
I too have never
utilized a grass strip. My personal runway minimum length is 3000',
although, as you have said Tom, the aircraft would operate from a shorter
strip. Short strips in Southern Oregon are all usually at higher
elevations. For me, it is not the takeoff distance that is a concern,
rather it is the landing distance. No stopping assist with a fixed pitch
prop. So, it's all with the brakes and with the roundout and flair that
starts before the numbers.

I routinely flew my
lancair 235 with a fixed pitch cruise prop in and out of a 2600 foot paved
runway at sea level. Climb performance was around 650 ft per min solo with full
fuel. I have never operated this aircraft from a grass field, so I can't
comment on the performance impact. My aircraft weights 930 empty and has an
O235 L2C with high compression pistons. I would get around 2400 RPM static. I
replaced the fixed pitch prop with a MTV1 and now climb around 1300 fpm.
Last week, I departed from a 3800 foot strip at sea level with a 130# passenger
and full tanks at 100 degrees F. I weigh 170#. The limited climb performance
was obvious, but I was able to accelerate in ground effect to a safe speed long
before running out of pavement. I feel like this was the limit for my aircraft
and ability. Later, with 20 minutes less fuel, long runways at 104F, we had no
problem whatsoever.
