Polaris Seaplane Parkflyer by Steve Schumate (jetset44-RCGroups)

For the lake... I have built a boat (actually an airboat). I have built a sailboat. Now its time to do some flying at the lake, and i'm thinking of a parkjet that has been long listed in my build list which at that time i dont have the reason to build one as there's no near by flying site to play it. Now i have just the right reason to build one, and its a great build. You wont regret it if you decide to build one. But! Make sure you really make sure no water can get in. Else, you will end up wishing 'if only i build it better'.

I would say you need an intermediate skill to build one of this without giving you the headache. Some simple fabrication and soldering skill needed. Follow the step by step guide by steve. Pay attention to every notes/remark made by steve in his build guide. Align parts that should be aligned, sand what should be sanded, fill any gaps/holes with glue. Make it water tight to save your electronics. Check that you have enough thrust in your power setup and check your CoG on every flight. You are good to go. It will take of the water easily.

My setup :

Blm : DYS A2822-8 260W 2600kv
ESC : 30A
Servos : HS 55 (Ail), 8g Esky (Rud and Ele)
Bty : Giant Power 11.1v 2200mah 25c
AUW : 21oz

Glue Used :
Epoxy
UHU Multipurpose
3M 77 Super

On the water:
This parkjet will float nicely on the water with the rudder partially submerge making it easy to move around. But u need to put in throttle to make it response. The faster your motor turn, the faster it response. This is due to its rudder located right behind the prop wash.

Im enjoying myself just by cruising around the lake with this parkjet.

Taking of the water :
My Polaris take off the water with a breeze in half throttle. For taking of, i just make sure theres no obstruction in the line of my Polaris will be taking off. Cruise in 1/3 throttle and gradually increase it to 1/2 throttle, and watch as it start gaining speed and the tip float begins to leave the water surface. Then with just a small and smooth input on up elevator it will take off  the water nicely. Most of my fellow rcier who watch it says it looks beautiful the moment it leaves the water.



Flight and landing :
Still got to familiarize myself with flying above the water. As the fear of drowning is still haunting me :)

Control wise, the rudder and elevator will gave you enough authority as it is mounted behind the motor. The ailerons is doing their jobs just great. But make sure to dial all controls in with some expo's and set your dual rate for fast and slow flight. Which i still trying to do, cause till today i just manage to made two flights out of it, cause by leaks. If only i had build it better :)
