Greetings to all mutually helplessly addicted flyers -A friend of mine (John Peschong) has a hay field which he desiresto place a runway for both part 103 and 61 restricted light airplane.He wants to build a Murphy Maverick or Rebel, which has some verygood short field performance numbers.There is about 1900 ft of runway, but with tree clearance and side-sideclearance requirements, the 'official' runway length will likely beabout1300 ft.I am trying to put together a list of actual performance numbersbased upon those who have a good feel for the Piet's performance:1 - GVW field elevation of numbers listed for below2 - Takeoff Roll distance (paved or turf)3 - Height at a known distance from start of takeoff roll.4 - Timed climb from 1000 MSL to 2000 MSL (seconds) at what temp and/or any other timed climbsdone.5 - Horsepower of ship, Engine prop pitch/dia info.6 - EVW of ship7 - any modifications aerodynamically from the original plans (airfoil,size...)The plans simply state '500 ft per minute for the first minute guaranteed,'butnothing else concerning performance was given. This was alsofor the model Aengine with about 40hp! Most are flying with at least 55-65 hpand some asmuch as 100hp.Thanks for the help.David Scott/-------------------- |~~_____/~~__||DAVID SCOTT |______ ______======)-+|scott(at)haulpak.com | o'~~|~~~ |--------------------/(O)________________________________________________________________________________

How high are the trees at the end. Could it be used as a one way stripif trees are only at one end? 1900 feet is more than enough for a Pietif trees aren't a factor. With good aproaches, anything down to about700 feet would be usable. I've been in and out of 700 feet with aTripacer, used to operate a banner operation with cubs out of about 800feet and have been into 1400 foot strip with the Howard!David Scott wrote:> Greetings to all mutually helplessly addicted flyers ->> A friend of mine (John Peschong) has a hay field which he desires> to place a runway for both part 103 and 61 restricted light airplane.> He wants to build a Murphy Maverick or Rebel, which has some very> good short field performance numbers.>> There is about 1900 ft of runway, but with tree clearance and> side-side> clearance requirements, the 'official' runway length will likely be> about> 1300 ft.>> I am trying to put together a list of actual performance numbers> based upon those who have a good feel for the Piet's performance:>> 1 - GVW & field elevation of numbers listed for below> 2 - Takeoff Roll distance (paved or turf)> 3 - Height at a known distance from start of takeoff roll.> 4 - Timed climb from 1000 MSL to 2000 MSL (seconds) at what temp> and/or any other timed climbs done.> 5 - Horsepower of ship, Engine & prop pitch/dia info.> 6 - EVW of ship> 7 - any modifications aerodynamically from the original plans> (airfoil, size...)>> The plans simply state '500 ft per minute for the first minute> guaranteed,' but> nothing else concerning performance was given.
