I would put the hand crank in, and put the nose wheel on a dolly, problem solved. The dolly would need to cradle the front wheel with some wood. You can put your weight on the back of the plane by the rudder, and the nose wheel will come up, put dolly just behind the nose wheel, and back up slightly with dolly behind the nose wheel while elevated, to drop the nose wheel into the cradle on the dolly.
At the risk of sounding terribly negative, this suggestion of the use of a dolly for the nosewheel is a non-starter. (Sorry for sounding so harsh). I've tried it, albeit on a larger, heavier aircraft. Even with fairly large rubber wheels (3" wheels on a professional mover's dolly) the slightest resistance encountered by either main wheel caused the aircraft to **** sideways; the dolly under the nose wheel would literally jerk sideways.
My interim solution was a combination of things. I installed a hand-crank rope winch which, I believe, saw prior duty on a boat trailer. I equipped the winch with cheap yellow polypropylene rope. This rope is far more stretchy than one would naturally assume it to be.
My method of moving our aircraft (typically about 1700lbs) up a slope and over the hump caused by frost heaving at the front lip of the hangar floor was as follows.
- push the airplane as far up the ramp as possible, then secure in place with a nosewheel chock installed both in front of and behind the nosewheel
- attach the winch to the tail tiedown hook (in this particular aircraft there is fantastic "beef" at this point in the structure because this is also the attachment point for the tailwheel spring)
- wind the winch up, placing tension on the rope (remember the chocks are preventing the airplane from rolling uphill and downhill)
- go back to the nose, remove the downhill chock and put it in my pocket, kick out the uphill chock and push the aircraft backwards picking up the chock as you walk past it and while using the towbar to steer the aircraft; the tension and stretch on the yellow poly winch rope acts as a gentle "helping hand" to move the airplane
- once the tension on the rope is relaxed, reinstall both chocks and repeat the process
This has proven to be a far safer technique than I had ever thought it would be, and it gives terrific control over trajectory of the aircraft. Cost is darned near nothing, especially if you find a used boat winch or similar.
The other solution, the one I use now, is an electric tug which fully supports the nose wheel, lifting it completely off the ground, thus removing it from the steering equation while also providing motive force to the aircraft.
