Have a 170 question

[Bruce Fenstermacher]

So is the 170A rag wing, or just has no dihedral? And the B has dihedral. Straight 170

Only the 48 is a 170 and a rag wing. The A from 49 to 51 have metal wings unbalanced elevator, do dihedral and small flaps that deploy to 50 degrees. The B model from 52 to 56 has metal wings, dihedral, large flaps that deploy to 40 degrees and a balanced elevator. Of course there are other differences between the models but those are the high points most consider at first blush looking at the 170 line.

Thanks guys!!!

I been looking at a couple of 170A's on trade a plane.

... I think with the mod, the wing has a higher lift coefficient, so you get more lift for the same power. In any case, this is what I know from doing flight-of-two takeoffs with a stock 170B. I could always outclimb the stock airplane.

What PROP did the "stock" 170-B have?

Sorry, I don't remember the prop details. I think both airplanes had the same prop, not a climb prop. The prop on mine wasn't changed when the STOL kit was installed. Both airplanes had approximately the same cruise performance, 117MPH or so at 2450 RPM. My 170 had 8.00x6 tires, and the stock one has 6.00x6 with wheel pants, and red paint -- so it cruised a little bit faster than mine by 1 or 2 MPH.

1300ft is doable especially with no obstacles. I've flown my 170 out of much less. Here are a couple videos going out of Buzzlatka's 1300ft strip surrounded by tall trees. This is with a stock wing and an 80/42 prop. It now has a Sportsman on it as well.

The 170 in the Buzzlatka video appears to have an empty backseat on takeoff. The machine behaves much differently with two adults, a boy, and full tanks.

I did have the back seat out. Actually its always out because I usually just fly with my wife, then have plenty of space for camping gear and the dog. But Buzzlatka and I do go in and out of that strip with 2 aboard and full fuel with our 170s.

1300 ft with no obstacles is no problem with 2 adults and a kid. My strip is a little over 1200 ft and has tall trees right at the ends. With no obstacles you can actually use all 1300 ft.

My 170 1st went into this strip stock c-145 motor with a 7653 prop. I later switched to a 7651 and noticed a little better performance. I went into this strip on a 70 degree day at around 1800 lbs. Thats 2 big dudes and 20 gallons of gas. It was very tight and the little tailwind of a breeze that picked up didn't help.

I would comfortably fly the wife and kids out of a 1300 ft strip with no obstacles. Could probably do it with full tanks and light bags.

If you start doing modifications like the seaplane prop or stol kit (robs setup) you could go out of a 1300 ft strip at gross with a little density altitude. I think his 170 could tow a 180 out of my strip.
