RCPowers - F1 Hydro 3D

F1 Hydro 3D

Instructions

IMPORTANT: This is NOT a beginner plane! If you are not already an intermediate to advanced flyer, do NOT get this plane, you will not be happy. Picture the F1 Hydro 3D as a super stunt plane, not something you want to start out on. If you are new to RC, get a flight simulator and learn how to fly before you attempt to fly anything.

*BUILDING TIP: The toothpicks add tremendous support and strength through out the boat. They act as rivets, really. I highly recommend using them; they are worth the small amount of extra weight. Yes, you may not use them if you'd like to save weight, but you will trade a minute increase in flight performance for a noticeable decrease in durability.

	1) "45" Control Surfaces
	Take a straight edge and a razor blade and “45” the control surfaces. Then tape them down with some good tape.

	2) Install Carbon Tube
	- The carbon tube goes about 3.5” back from the leading edge. - Lightly score (do not cut all the way through) where you want the carbon to go. - Then “pluck” out the foam with a small standard screw driver. - Epoxy in your carbon tube. It should now be flush with the foam and not be sticking out the other side.

	3) Glue Down Outside Sponson
	- Start from the back of the boat and work your way forward. - Let this piece dry in place and build the rest of the sponson around it.

	4) Glue Down Inside and "Square" Sponson Parts



	5) Seal up Sponson
	Once the 3 sides of the sponsons are dry, then make sure all the joints are water tight. I slop in some 5 min epoxy just to make sure.

	6) Close Up Sponson
	Once you are sure that it’s all water tight, glue down the bottom piece real good and cut off the access.

	7) Glue on Fuselage



	8) Install Control Horns

	9) Shave Nose


	10) Install Rudder
	- Bevel the rudder as needed and tape down both sides real good. - Then trim it here and there so it moves left and right without hitting on the vertical stabilizer.
	11) Know Where to Mount the Motor!
	- No matter what motor or prop you use, make sure the bottom of that prop is not hanging much farther than 1 ¼” If the prop is any lower you will start to hit the grass and water.
	- You also want the motor as CLOSE to the wing line as possible for the best performance.
	- The Welgard jet motor with a 6x4 will give you the best performance in the air. - The TurboProp 2205 motor will give you good light weight all around performance with a 7x3.5 prop.

	12) Make Break Away Motor Mount
	- With this all in mind, mount your motor right where you want it to be depending on what prop you are using. Again, whatever motor or prop you are using, make sure the prop does not hang lower than about 1 ¼” from the bottom of the nose tip as pictured or you will hit the ground. - Like the original F1 Hydro, the glue joint of the motor mount is what you want to come apart in a crash protecting your nose, motor, and sponsons.


	13) Install Fuselage Top and Vertical Stabilizer


	14) Finish the Nose


	15) Cut out Hatch


	16) Make Servo Tray


	17) Install Servos
	- If the servo install looks too crazy for you, just install them on the outside of the boat.

	- When using the carbon / metal push rod combo for light weight, go with something like JB Weld glue as it works well to get carbon and metal to stick together.

	18) Install Linkage




	19) Glue the Wings On
	The wings are fun, you’ll like them. Trim them off when you outgrow them.
