You'll be fine. The ME fleet are about to introduce the Helmet Mounted Pedal System (HMPS), which allows you to operate the rudders through power of thought. Trials are ongoing but early indications are encouraging. By thinking 'Hot Dessert' you get left rudder and by thinking 'Choice of Main Course' you select right rudder.
The beauty for you of course, is that you can now remove the seat and stand up, therefore, height is not a problem. The only downside is that the prototype helmet weighs 70Kg and only comes in one colour.
Good luck.
