SNIP I have my HR for sale.... and I have a serious buyer who wants to operate
on grass.
My operations are always on pavement. I've ventured onto grass recently..
. tried removing pants 1st just to see what the performance issues were.
Rocket is a lot slower and uglier in that config.
I searched back into rocketlist archive regarding grass field operations.
Rob Ray's comments (Desser tires) are good... Andrew in New Zealand, gra
ss operator.
Anyone else ? What are issues ?
If you are caretaker of your grass strip, how close do you crop the grass.
. roll the surface... keep it smooth ??
Thanks in advance for your comments.

Rockets love grass. What's the problem? I'd rather land on a grass strip than paved under normal conditions.
We roll our strip once a year, mow to normal height, and keep an eye out for mole or other damage. No different than keeping an eye out for chuckholes in pavement.

John,
I have operated my Rocket off of my very soft 1800' strip for nearly five years with no issues. I operated my RV4 from the same strip and many less improved before that, no worries. The airplanes were designed for off field operations until more speed became the ultimate goal from the "group" and fairings and wheel-pants became closer faired and nearer to terra firma. I modified my HR2 by removing the Sam James pants and fairings and purchasing a set of Team Rocket leg fairings and Vans Pressure Recovery pants. Using Steve Sampson's RV4 blog as a guide, I installed a set of Aero Classic 380X150X5 main tires and one of Vince's lightweight tall tailwheels on my API tailwheel assembly. My friend Ronnie helped me trim the pants at a height to be 4" above ground at the rear of
the tire in level flight attitude. We cut the hole so the pant blends down around the center of the wheel but is higher at the front and back. The first test flight was on a muddy day and I immediately noticed the difference in ground handling and the first landing on soft ground was noticeably less "digging in". The side benefit was pavement handling improved as well. Other that that I have gotten very adept at 69 knot approach speeds and landing on the first blade of grass on short strips. I recommend nothing shorter than 1000' feet unless you have a mission requirement for such.  I have also experimented with partial flap takeoffs. Ten degrees does help get off quicker into ground effect. That's all I have to say about that!
Good Luck!SmokeyHR2

Here are some facts culled from several sources about the bombing....
(1.) Out of 28,410 houses in the inner city of Dresden, 24,866 were destroyed. An area of 15 square kilometres was totally destroyed, among that: 14,000 homes, 72 schools, 22 hospitals, 18 churches, 5 theatres, 50 banks and insurance companies, 31 department stores, 31 large hotels, 62 administration buildings as well as factories such as the Ihagee camera works. In total there were 222,000 apartments in the city. 75,000 of them were totally destroyed, 11,000 severely damaged, 7,000 damaged, 81,000 slightly damaged. The city was around 300 square kilometres in area in those days. Although the main railway station was destroyed completely, the railway was working again within a few days.
(2.) The Nazis made use of Dresden in their propaganda efforts and promised swift retaliation. The Soviets also made propaganda use of the Dresden bombing in the early years of the Cold War to alienate the East Germans from the Americans and British.
(3.) Development of a German political response to the raid took several turns. Initially some of the leadership, especially Robert Ley and Joseph Goebbels, wanted to use it as a pretext for abandonment of the Geneva Conventions on the Western Front. In the end, the only political action the German government took was to exploit it for propaganda purposes. ("Dresden: Tuesday, February 13, 1945". By Frederick Taylor, page 420-426)
(4.) The destruction of the city provoked unease in intellectual circles in Britain. According to Max Hastings (a renowned British historian), by February 1945, attacks upon German cities had become largely irrelevant to the outcome of the war and the name of Dresden possessed a resonance for cultured people all over Europe — "the home of so much charm and beauty, a refuge for Trollope's heroines, a landmark of the Grand Tour." He argues that the bombing of Dresden was the first time Allied populations questioned the military actions used to defeat the Nazis.

Hi,
as a lurker on the Rocket list ( just interest as I fly a microlight) I am
loth to post this but I just cannot let a discussion of Dresden pass by
without comment.
Being 81 I lived through the war ( and got bombed out) and perhaps have a
different viewpoint than those `second guessers` born later who have had the
luxury of hindsight when evaluating what should and should not have been
done.
Max Hastings is of course right when he says that there was `unease` in
intellectual circles. There was unease after we bombed Hiroshima and
Nagasaki but this was a problem which had to be solved IMMEDIATELY. The
decision would not wait for the luxury of intellectual discussion. There was
a war on, decisions had to be made NOW. The Germans and the Japs were still
fighting, they were not giving up. We had them on the back foot certainly
but that is the time to attack, not ease off. There was no `unease` among
the men who had to go in and die on the ground in Germany or storming the
beaches of the Japanese homeland. They all said `Serve the bastards right,
they started it`
There seems to be the idea that Dresden was sitting there making Dresden
porcelain figures. Were they hell. Any more than Bath or Coventry were.Bath
was stuffed to the gills with Admiralty Planning Departments and you
couldn`t throw a stone in Coventry without hitting an engineering works.
They were all `legitimate` targets.
Remember too that this was the end of the war and we had brought bombing to
a pretty fine art. We had a lot of practice and lost a lot of Bomber Command
and the American Airforce refining the problem. If Germany had been as
expert in bombing in the early part of the war as we were then do you think
that she would have worried about Bath, Bristol, Coventry, Plymouth, London
having `cultural resonance`. Of course not. They did their best to wipe out
those cities, it is just that ,like us at that time, they were not very good
at it.
Poor old `Bomber` Harris got a lot of stick just for carrying out his
orders. He was denied the rewards which were handed out to the commanders of
every other arm of the Services. His men ,who died in their thousands, were
denied a Campaign Medal even. Suddenly, when the need for them had passed
everyone became holier than thou` and began to voice doubts about the
bombing campaign, and decrying the efficacy of the results.
Sorry to but in
Pat
