Horton STOL Procedures on a 206

Horton STOL Procedures on a 206

I have a 1972 U206F with a Horton STOL kit installed. I just got the plane and there doesn't seem to be any documentation detailing the procedures for the STOL kit. I don't know what my new stall speeds are, if my approach speed has changed, or what my takeoff and landing rolls are now.

I'm playing it safe and staying with the POH but obviously having this information would be helpful. Does anyone know where I can get the info?

Thanks,
Anthony

Re: Horton STOL Procedures on a 206

So after some experimenting with my instructor here's what we've found. With full flaps at altitude we got as slow as 40 MPH (about 35 kts) and still maintained good aileron control. So even at the bottom end of the ASI we didn't get a full stall! This certainly doesn't mean that the plane WON'T stall but it appears we have up to 25 MPH of stall insurance. I'll still be flying as per the POH of course but the STOL kit seems to add quite a nice comfort zone.

These results were similar in various other configurations as well. We've decided to minus 10 MPH and call it an even 15 MPH of wiggle room.

Take care all!

Anthony

Re: Horton STOL Procedures on a 206

On my  1963 172-D , i had micro vortex generators instlaled and flap gap seals.while doing slow flight at 1600rpm, i can add 40* of flaps and bring the airspeed  down to below 40 or off of the scale with the stall warning horn blaring. its a great margin of safety too. when on short final ,i try to maintain 60MPMH  .

Re: Horton STOL Procedures on a 206

I installed the Horton kit on a 172K shortly after purchasing the aircraft.  I did not experiment a lot with the aircraft before the kit was installed but I have since.  There appears to be about a 5 knot reduction in airspeed at stall.  The stall is mild and the aircraft is very controllable up to the stall. 

I can make the airspeed indicator go to zero and still have the aircraft flying. You should see the look on pilot's faces when they see that the first time.  After much testing with a GPS the stalling speed appears to be 38 knots at a 2100 pound gross weight and 40 degree flaps.  I regularily fly into short grass and gravel strips and feel safe.  Approach is about 55 to 60 mph indicated.

My only complaint with the aircraft is prop tip erosion from gravel (despite my best efforts to avoid it) and dismal climb performance.  Nothing another 50 hp would not solve.  I can easily be down and stopped over 50 trees in 1000 feet. With no trees I could stop in 400 feet. On a warm humid day 2400 feet with trees can be tight to take off from.

I regularily fly a 172I on floats with 180 hp and a Horton.  It handles great as well. It just levitates off of the water.

Re: Horton STOL Procedures on a 206

One thing is missing in all the previous discussions . . .  That of the accuracy of the air speed indicator.  As mentioned, there is no difficulty dropping the stock indicator to zero or in my case it jumps from 0 to 30 indicated at a pretty rapid rate.  While GPS speed is accurate there is little time to focus on the little digits during final approach.  For all STOL equipped aircraft I recommend the LRI (Lift Reserve Indicator).  These allow a rapid - real time - assessment of reserve lift.  One version of this instrument is available at http://www.liftreserve.com/ and it is worth every penny of the investment.

Interestingly - but not surprisingly - FAA does not recognize this as a "primary" flight instrument.  They would rather that you rely on your inoperative inaccurate air speed indicator that was never meant to function below 40 knots.  For anyone set up for STOL and short-field operations this instrument is definately worth a look.

Be careful up there, and . . .
