122.45 does your Jodel have tailwheel steering? If it doesn't then the only way you will maintain directional control in a crosswind is by judicious use of the brakes. Even if it does have steering brakes may still need to be used. It should be quite hard to get the aeroplane to stand on it's nose by using one brake. Don't stand on the pedals but equally, don't be afraid to use them. As you slow down into the 30-20knts range that is giving you the problem, a trickle of power up to say 800-900 rpm should provide enough airflow to energise the rudder without adding so much thrust that you stop slowing down. Try it on a long field first!!!!!
I have heard that Jodels aren't very tolerant of sideways thrust being applied to the undercarriage but they can't be that bad or there would be legless Jodels all over the place. Any Jodel owners out there care to comment?
Another alternative is to buy an Auster. With a free, unlockabe, castoring tailwheel and a powerful rudder they can be VERY entertaining in a crosswind.
