Adhesives Required HAN8000 6-Minute Epoxy Threadlock Using the Manual This manual is divided into sections to help make assembly easier to understand, and to provide breaks between each major section. In addition, check boxes have been placed next to each step to keep track of each step completed. Steps with a single circle () are performed once, while steps with two circles ( ) indicate that the step will require repeating, such as for a right or left wing panel, two servos, etc.

Float Installation (J-3 Cub) Required Parts • Fuselage • Landing gear • Ventral fin mount • Ventral fin • 3mm setscrew (4) • Hex wrench: 1.5mm • Nylon bracket (4) • 5/32" wheel collar (4) • 3mm x 12mm sheet metal screw (16) • 2mm x 12mm sheet metal screw (3) • Nylon strap (2) 1. Remove the packing material from the landing gear. Attach it to the fuselage using the two nylon straps that were used to hold on the main gear and the two nylon straps included with the float kit.
2. Attach two of the brackets to each float using eight 3mm x 12mm sheet metal screws. Each float uses two brackets, so you’ll install four brackets in all. 3. Use a file or rotary tool to make a flat on the top of each of the landing gear extensions.
4. Attach the floats using the four 5/32" wheel collars and four 3mm setscrews. Make sure to use threadlock when tightening the setscrews onto the flats made in the previous step. Note: One float has holes drilled in the aft end for the rudder bracket. This float is mounted on the same side as the rudder linkage.
5. Attach the ventral fin mount using three 2mm x 12mm sheet metal screws. 10 6. Remove the bottom 1/8" (3mm) of covering from the ventral fin using a hobby knife.
7. Attach the ventral fin to the mount using 6-minute epoxy. Make sure the fin is in line with the vertical centerline of the fuselage.
1. Attach a nylon bracket to the rear of the float using four 3mm x 12mm sheet metal screws. 2. Place a 5/32" wheel collar in the center of the nylon bracket. Slide the rudder assembly through the nylon bracket and the wheel collar. Secure the steering arm at the top and the wheel collar using 3mm setscrews. Note: Remember to use threadlock on . both setscrews.
3. Enlarge the middle hole in the steering arm with a 5/64" (2mm) drill bit. Secure a pushrod connector on the steering arm using a pushrod connector backplate. 4. Enlarge the outboard hole in the rudder control horn using a 5/64" (2mm) drill bit. Secure a pushrod connector on the rudder horn using a pushrod connector backplate.
5. With the pushrod cable inside the pushrod tube, attach the tube to the float using a full brass strap and two 2mm x 10mm sheet metal screws. The end of the pushrod tube is 1 1/2" (38mm) from the end of the float. 6. Use two full brass straps and the half brass strap to attach the pushrod tube to the bottom of the fuselage. Leave the straps slightly loose so it can be moved around for the next step. Note: These straps are secured onto the crossbraces on the bottom of the fuselage.
7. Use a tie wrap to attach the pushrod tube to the landing gear. Slide the tube as necessary. Once attached, go back and tighten the screws for the brass straps. 8. With the rudder centered, secure the pushrod cable using a 3mm setscrew. Place the steering arm parallel with the end of the float and secure the cable at the steering arm end using a 3mm setscrew.
9. Position the water rudder parallel to the rudder of the aircraft. It may be necessary to loosen the setscrew at the steering arm to do so. 10. Test the operation of the water rudder with the 11. Adjust the water rudder to move up and down by tightening or loosening the 4-40 socket head screw on the rudder shaft. The water rudder should be able to deflect up if it hits an obstruction in the water. aircraft rudder.
Float Installation (Ultra Stick 25e) Required Parts • Fuselage • Landing gear • 3mm setscrew (4) • Nylon bracket (4) • 4-40 x 1/2" socket head screw (3) • 5/32" wheel collar (4) • 3mm x 12mm sheet metal screw (16) 1. Locate the holes on the fuselage for the rear landing gear. These are located behind the air exit on the fuselage. Use a hobby knife to remove the covering. Attach the landing gear to the fuselage using three 4-40 x 1/2" socket head screws.
2. Remove the wheels and wheel collars from the main gear. 18 3. Attach two of the brackets and float mounts to each float using eight 3mm x 12mm sheet metal screws. Each float uses two brackets and two float mounts, so you'll install eight pieces in all.
4. Use a file or rotary tool to make a flat on the top of each of the four axles. 5. Attach the floats using the four 5/32" wheel collars and four 3mm setscrews. Make sure to use threadlock when tightening the setscrews onto the flats made in the previous step.
Note: One float has holes drilled in the aft end for the rudder bracket. This float is mounted on the same side as the rudder linkage.

The end of the pushrod tube is 1 1/2" (38mm) from the end of the float. 6. Bend two full brass straps to attach the pushrod tube to the top of the fuselage. Leave the straps slightly loose so it can be moved around for the next step.
7. Use a tie wrap to attach the pushrod tube to the landing gear. Slide the tube as necessary. Once attached, go back and tighten the screws for the brass straps. 24 8.

Float Flying Flying from floats can be great fun. There are a few things to remember when you hit the lake. First, make sure you pick a location where you can take off and land parallel to the shore line with no obstructions. You will want to make sure you are taking off and landing into the wind. Verify your water rudder is down and the plane is powered up. Set the plane into the water and begin to taxi out. It is common to hold full up elevator (back stick) during all taxi maneuvers.
Float Flying Landing on water is very similar to landing on hard ground. Set up like you normally would and turn onto final approach. Maintain power during the approach, as a plane with floats tends to land slightly faster than when equipped with landing gear. As you come down, begin to flair and hold it until touchdown. Once you have touched down on the water, as the plane slows down, begin to feed in up elevator as the plane settles.
2006 Official AMA National Model Aircraft Safety Code GENERAL 1) I will not fly my model aircraft in sanctioned events, air shows or model flying demonstrations until it has been proven to be airworthy by having been previously, successfully flight tested. 2) I will not fly my model higher than approximately 400 feet within 3 miles of an airport without notifying the airport operator. I will give right-of-way and avoid flying in the proximity of full-scale aircraft.
2006 Official AMA National Model Aircraft Safety Code 3) At all flying sites a straight or curved line(s) must be established in front of which all flying takes place with the other side for spectators. Only personnel involved with flying the aircraft are allowed at or in front of the flight line. Intentional flying behind the flight line is prohibited. 4) I will operate my model using only radio control frequencies currently allowed by the Federal Communications Commission.
