Every time I visit the lake the more I want to finish this Walrus. The calm water and open wide space is waiting for the Walrus to sail and take off. The upper wing plans are already printed (8 pages) and ready to be transfered to foam. The wing consist of 3 segments, left and right wing and wing base in the middle. Each segment have two parts, top and bottom parts. The top parts need to be bended to follow the shape of the wing formers or ribs. I use plywood for the wing spar instead of balsa like my previous corsair that easily to snap from a small crash. I also thicken the wing a little bit with the hope it will generate more lift.
I am very excited to start building this plane, this plane is very unique. The plane is Supermarine Walrus, it is a seaplane and a biplane. It fits so much with what I want, I was looking for a seaplane with a single engine. I also searched for the specific seaplane, the one that use the fuselage as the float, not with separate floats. I also want a slow flyer, the biplane type is perfect. Pusher prop configuration on Supermarine Walrus also an advantage. Every Saturday I sail my RC boat on Lake Babakan near my place, I think if I have an RC seaplane it would be fun. I plan to use power plant from my previous Cessna 185, so the weight will be strictly not above 1200 gram. Both wing area is 45.6 sq.dm, so with 1200 gram the wing loading will be 26 g/sq.dm or 9.19 oz/sq.ft. It makes the plane very easy to airborne, like a glider.
As I promised that I will post an update on Wednesday, this is what I've been doing for today, so far. I've managed to assembly the canopy as the battery compartment hatch. The canopy is temporary, it just for test flights before adding cockpit interior and other details onto it. I have to remove formers on fuselage which behind the cockpit, because if I use it, it will not fit to the fuselage part that just below it.
I finally finished the F4U Corsair's plans for more than 3 months working on it. I started on January 10th and finished on March 26th. This Corsair is my 7th homemade plane, and it is also one of the coolest looking plane that I ever made. The most difficult things when designing this plans was when design the constructions of the wing. I use two balsa spars, that was new method for me. It worked out well, until I crashed the wing to the concrete
This is my 6th homemade RC airplane, but I share the plan first with you. Actually this Cessna 185 was not on my wish list, it was a commissioned model. I was paid by my fellow Gaero forum member to design the plan, build it and test it. This plane is the first plane that crashed of her first maiden flight, although I never had it on the previous plane. Then after investigated the crash, I had a conclusion.
