 Posted: Tue Mar 10, 2020 7:57 pm Post subject: Mark III Taxi Crosswind Limit |
 |
|
I am going to be transitioning away from a Cessna 182 this year up here in Wisconsin, and am looking at even lower and slower, so pardon as I ask about Kolbs as I do some dreambuilding for my next plane. Many of my initial inquiries have been addressed on the listerve.
I'm about 240#, and would likely be flying solo most of the time.
What is the experience of the group with regards to a "prudent" crosswind for taxiing (assuming good elevator and aileron technique)? (My initial post asked about "safe". Safe could arguably be 0kts. I've landed the 182 at night with 18G24 crosswind (after several tries), so am looking for what the prudent crosswind limit is for a well-practiced pilot.) Thanks.

A Kolb MKIII will handle crosswinds better than most if not all light sport airplanes.
You specifically asked about taxiing, I depends on how the plane's tail wheel is rigged. If you have the factory option locking/full swivel with the light springs then 10-15 MPH is about the limit. Change the springs to a compression type where you can keep the cross wind from unlocking the tail wheel then 15-20 MPH or slightly more. On a cross country trip I landed right into a 20 MPH headwind just fine but did a bunch of 360 or more turns on the taxi way going for fuel and sheltered parking (and I was standing on one of the brakes the whole time). Changed the springs when I got home.
A word of warning, transitioning from a 182 will be a challenge. Your experience and training will have you flaring way to high with a landing gear bending stall. Don't ask me how I know this. These light planes slow below stall a tad quicker than you are prepared for. Think about flaring at one foot. You first landing should be done with enough power that it acts like a 182 then SLOWLY work towards landings with less power.
As usual worth what you paid for it.

My MK 3C with 80 hp Jabiru 640# empty w/vg,s 175# solo stalls at 28 mph. You have to be on your game to handle 15 mph crosswind from90 degrees

Rick's post was right on- A Kolb MKIII will handle crosswinds better than most if not all light sport airplanes.
You specifically asked about taxiing, I depends on how the plane's tail wheel is rigged. If you have the factory option locking/full swivel with the light springs then 10-15 MPH is about the limit.
I also had a breakaway tail wheel, and did several donuts in the middle of a 10,000 foot runway much to the consternation of the tower. I had no problem with the crosswind. I however solved the problem differently by hogging out some of the interior of the tailwheel body, so that it required full throw to break away the tail wheel. I have had no problem with the modification, but Rick was right, that much cross wind isn't all that much fun. The plane can handle much more than you can.

Thanks for your comments and suggestions. I'll need a tail wheel endorsement, too.
So, where does one find the details about how to rig the compression springs for the tailwheel, or the hogging out tailwheel, or sissy bars on the wingtips?

If you have a "break away tail wheel" from Kolb you will notice when you take it apart that there is a ball that releases the tail wheel to free rotate. Since the housing is of alum, I used a square router tool to gouge out more of the housing so that it would take almost a full deflection of the rudder before it broke away.
My first experience with the tail wheel breaking too soon was on a cross country trip coming back from a Alvord Desert fly in. I landed at a remote Oregon town and decided to land on the main strip. I had no problem with the direct crosswind, but as soon as my speed got below 20 MPH the tail weather vaned and sent me out into the Sage brush. Since the engine is mounted high I had no problem other than a rough taxi to get out of the ditch. I flew off the taxi way when I left.
Not sure how Rick rigged his springs.

I rigged my tail wheel springs so that they were snug so that I had good steering control but not compressing the springs any. There is enough spring travel in the compression springs to absorb any shock but have limited travel enough so that in a heavy cross wind I can compress the springs to the limit and hold the tail wheel where I want to go against a cross wind. My stock tail tail wheel has never unlocked before full travel so I haven't modified my tail wheel. In fact when I first put the compression springs on I couldn't get the tail wheel to unlock. I had to then modify the tail wheel control arm. I drilled the control arm with new holes inboard of stock holes so that I could get the tail wheel to full lock where it would unlock for full swivel. I hope this is clear.
As always worth what you paid for it.
