Here is an economical suggestion.
material list
one cable TV converter with remote.
sufficient 12-2 wire with ground to get from converter box to relay switch.
relay switch
110-12volt converter out of RV Trailor
12volt off road power winch
1/8 in cable from home base sufficent length from back of hanger to outside
where you will attach to aircraft
misc clamps, hooks to attach to airplane.
misc hardware to mount winch to back of hanger
I used the remote converter to trip the relay switch thus passing 110volts
to the inverter located near the winch at the back of the hanger. The
converter is located in the left front corner of the hanger so the infrared
remote can activate the converter. (Distance is a factor with the infrared
sensor).
I hook up my 360 using two wooden dowels covered with auto radiator hose
slipped into my wheel gear assembly. ( I have outback gear) These dowels are
attached to a nylon rope and a pully is attached to the winch cable thus
allowing the rope to roll through the pully and apply equal force to each
wheel. You might tie to the tail if you so desire but I wanted to eliminate
the vertical force component of the winch. The remote works fine unless you
are farther than about 30 feet. What I usually do is hookup the plane, get
it all ready, walk towards the converter until it activates then return to
the plane and control its entrance into the hanger. Once all gear are on
the floor, I stop the winch and push the plane to the final position.
Safety factor in case the remote fails, I have sufficient time to disconnect
the power source and prevent a tail aft hanger collision.
I used the smallest winch available at your local parts store. The cable
length was insufficient for my use so I had to acquire a new length of
cable.
The converter is available from your local RV trailor supply stores.
Good luck.
