Hi...looking in to what wheel and brake combo to use. I have decided to go withthe 800-6. Looking at the Matco variety on AS&S. Can someone explain the StaticLoad figures and the Load limit figures? What Part number are other buildersusing? I intend flying off a grass strip so am going for the larger tyre. Alsowhat are the pros and cons between hydraulic and cable brakes?Sorry for what probably sounds like a mundane question but im stumped!ScottyAustralia--------ScottyTamworth, AustraliaBuilding a Corvair Powered Pietenpol Air Camperwww.scottyspietenpol.comRead this topic online here:http://forums.matronics.com/viewtopic.p ... __________

I've operated my Cessna 180 for decades with 6:00-6 tires, frequently off of grass strips. Even a beach one day, and often at gross weight (2,550 pounds). I've landed off-airport on a mesa a few times as well, keeping a keen lookout for prairie dog hills.No problem.For an alternate opinion, see this:http://www.bentpropproductions.com/Go for the hydraulic breaks. If they are sized right, they'll give you smooth, solid braking with minimal maintenance.Static load is the load on the tire while the plane is standing still on the ground. Limit load is the maximum load encountered during a landing.David Paule> >> Hi...looking in to what wheel and brake combo to use. I have decided to go > with the 800-6.

As with David's experience, so with mine. NX41CChas 6.00x6 on the main gear, with hydraulic brakesstraight off an older Cessna 172. I operate offof grass whenever possible and I love the waythe Piet flies off of grass with this setup. Iknow that the people who have motorcycle-typewheels have things a little bit different thanwe who have fat tires and spring or bungee gear,but they both have their pros and cons.I prefer the slightly larger and fatter tiresfor appearance as well. The smaller ones seem tobe out of scale for the airplane.The brakes on the airplane work very well in allconditions, readily hold the airplane during staticrunup, but are not overpowering for the 1080 lb.gross weight.Oscar ZunigaAir Camper NX41CCSan Antonio, TXmailto: taildrags(at)hotmail.comwebsite at http://www.flysquirrel.net ________________________________________________________________________________

I also have Cleveland brakes off (I believe) a 172, but I have 21"motorcycle rims. I use the Matco MC-4 master cylinders, which have a pistondiameter of .625". I believe 6.00 x 6 Cleveland brakes have a 2" diameterpiston (don't remember exactly), which would mean a 50 lb push on the mastercylinder would generate a hydraulic presure of 50 /( p(.625)2/4) = 163 psi.When this pressure is applied to the brake caliper, it generates a force of163 x (p(22/4)) or 512 lbs, so you get about a 10:1 advantage.With the tall wheels, I find my brakes are adequate for stopping and to holdit for a runup, but they can't hold it against full power.Jack PhillipsNX899JPRaleigh, NC-----Original Message-----

Thank you all for your replies. I am looking at the Matco W60 setup from AS&S.These are the specs. Does this look reasonable?Regards ScottyMATCO mfg produces a superior 6 inch wheel and brake assembly for use with aircraftrequiring less than 1420 lbs per wheel. This model uses 1.25 inch TAPER/ROLLbearings. (Check the product comparison table for other bearing and caliperconfigurations).DimensionsThe W60 is a 6 inch wheel with 4.375 inch width with an additional 1.23 inch caliperspacing. Bearing spacing is 2.5 inches and axle spacing is 1.25 inches.The total weight of this wheel and brake assembly is 7.1 pounds. The bearing axlediameter is 1.25 inches.PerformanceThe W60 is designed for the following standards: Static Capacity: 1420 LBS Load Limit: 4260 LBS Maximum Accelerate/Stop Kinetic Energy: 189604 ft-lb Torque Rating (@450 PSI)[/b]--------ScottyTamworth, AustraliaBuilding a Corvair Powered Pietenpol Air Camperwww.scottyspietenpol.comRead this topic online here:http://forums.matronics.com/viewtopic.p ... __________
