Posted: Sun Jan 26, 2014 7:48 pm Post subject: turf runways

I have steered clear of grass runways in my RV-10 since there is so little clearance below the wheelpants, but I was wondering what experience others have had?  Those of you who fly off of grass, what sort of criteria and conditions do you require?

    I'm interested in moving to an Airpark (probably TN) in the next few years and not having to limit the search to paved runways would sure open the opportunities.



Thanks,

Marcus

We're talking grass here.  If the grass is long enough to cause damage 

to the pants it's probably long enough to prevent you getting in the air.

The thing that destroys the pants are vibrations from many operations on 

a rough runway.  Drive a car down the runway .... at 40 MPH or more 

you'll feel roughness.

I live on a 2200' grass runway.  When I built my -10 I raised the wheel pants a little higher, maybe an extra 3/4-1" is all I could get.  I also made the clearance around the wheel approximately 1" all the way around.   I've had no issues and no wheel pant damage so far in 3 years and ~270 hours.

The bottom of my wheel pants are left with primer color only due to rubbing against grass.  However it is not visible unless you are removing the wheel pants. 

Do not archive.

I took my pants off for winter. It costs me about 8 kts but necessary to avoid damage.

What might seem counter-intuitive, in the desert Southwest, pants are 

needed for engine cooling.

The added drag and lower airspeed reduces air over the engine, resulting 

in hotter temps.

I've forgotten how much Deems said his temps came down after he added 

wheel pants, and I seem to recall the speed penalty was over 10 kts 

without the pants. Currently planning on doing pants during phase 1, and 

not before first flight.

I operate almost exclusively off of grass.  I have had some issues with vibration causing the mounting hardware to shake loose.  I solved that with Sean's spacer for the mains.  The only other thing I notice is a very slow erosion of paint on the bottoms.  You need to watch out for ant mounds and gopher holes though.  The 10 works great on grass.

Just make sure you can get your fingers between the tire and the pants all the way around (and make sure that is STILL the case when you replace the tires).  Also, when landing on grass increase the inflation by 5 or so pounds, you'll be just fine.  Landed at Cedar Mill TX 3 times, Johnson Creek ID about 12 times, and Smiley Creek ID twice.... neither I, or any of the RV'rs in the group have ever had a wheel pant issue.

I operate my RV-10 in and out of a turf runway at my residential airpark on

a regular basis (WN29 - see

http://www.blueribbonfarmsassociation.com/airstrip.shtml ) and it is a fine

performer.  Occasionally the wheel pants get a little ding on the bottom,

but it is not from the grass but rather crossing ruts made by others.  The

RV-10 has such a luxurious amount of power that even soft turf runways are

not a problem unless you combine that with high altitude, short field, and

obstacles that would make a Maule driver have second thoughts.



And if you EVER DRIVE A CAR down our turf runway, especially at high speed,

there is going to be an angry mob taking photos and chasing you out of town.

Don't do it unless it is your privately owned turf runway.

Looks nice. Normally, the gear fairing is held in place by the lower 

pant. How did you keep the gear fairings in place without the pants?

I have flown into SC00 Triple Tree SC twice. We sat watching everyones pants shake like crazy and that runway is supposedly golf course smooth. If I lived on a grass strip I would beef up wheel pant mounts(switch to stainless) and fiberglass or just remove them. 



Maybe we will hear from Bill "Living the life in an airpark with turf" Watson. He might have to put some snow skis on this week.

They actually stay on just fine. They are attached at the top, and the only thing I did different is taper them down as far as I could. They actually stay in place without any special work on the bottom. The nose strut is even easier, it already has screws to hold it in place. I did have to change the piano hinge set up on the mains - a pin to go up, and a pin to go down.

Without the pant brackets, and with hub caps, there's not much drag to worry about.

What you lose in speed/time, guessing...6 kias/15 min per long xc would be nothing compared to time and materials repairing broke pants on a grass strip. I would take my pants off in a heartbeat to save $170/mo hangar rent and walk out to my hangar.

If you go with the Desser Monster retreads you'll sit a bit higher and have more clearance.

Well, the Monster retreads do have a bigger diameter, but you can also add diameter without the extra wt of the thicker Monster tread by using 6:00X6 tires instead of the specified 15X^:00X6 tires Vans calls for. Or you could use 6:00X6 Monster retreads for a HiRider version.
