I will assume that you want to trailer over a long distance and not just a mile or two to the nearest airport.
First off, use a light trailer. A car hauler
will transfer every road bump into your airframe since it is sprung for cars and light truck loads. Lightly sprung boat trailers work great with some modifications like longer tongue, winch for pulling the Kitfox up onto the trailer, ramp decking for main gear tires, tool box ect. Remember you are only hauling 600lbs. approx.
1. Make sure fuel tanks are 1/2 empty or
better completely empty. This will reduce the stressed on the rear wing spar attach points.
2. Remove and safely store the turtle deck in your tow vehicle.
3. Winch the Kitfox up on the trailer before folding the wings.
4.
Elevate the tail onto a support bracket that attaches securely to the trailer and utilizes the through tube near the front of the tail wheel spring attach bracket. This is also done before the wings are folded otherwise the tail will be very heavy and hard to align the support bracket. This can be a homemade bracket. This through tube will accept a length of redi-bolt that you will run through the support bracket and the Kitfox fuselage. This support will take the weight of the folded wings and tail section of fuselage. The tail wheel and rear fuselage will not be able to handle the shifted weight of the folded wings during transport. This is how vertical tail posts got broken in combination with too heavy of a trailer suspension. Damaged tail posts are not always easy to detect just by visual inspection.
4. Unpin the front spar and fold one wing back , then the other. Secure the wings with supplied hardware that should come with the aircraft.
Caution! Before folding, on my model 3, I had to have the flap handle in a specified setting and the control stick centered to avoid damaging the linkages from control rods to flapperons during wing folding. Your model 2 has the same control system if memory serves.
5. When securing the airframe to the trailer use ratchet straps to secure only the main gear tires to the trailer deck. This allows the aircraft to bounce on the main gear/tires to absorb road shock. Do not use other strong points on the airframe to tie the airframe to the trailer. This will override the main gear suspension and again transmit road shock to the airframe. Securing the airframe incorrectly will put more stress on the airframe during a moderate distance haul than likely a lifetime of flying.
6. Secure flight controls, rudder and elevator with padded boards or the like to prevent them from moving during transport. I'm making the assumption that you have loaded the Kitfox to have the tail forward and not the the nose. Secure the stick too with with bungee straps or seat belts.
If you have a two-stroke motor you may need to secure the prop so it does not windmill the whole trip.
7. Use support rods for the forward spar attach points down to your strut attach points on the fuselage. This will take stress off the unsupported front spar during transport.
8. Some owners like to seal up the open turtle deck area against rain and debris during long hauls. Shrink plastic could be used.
9. Make sure all switches are off on the panel and secure the doors.
