Scale Supermarine Walrus - Sea Biplane 1200 mm [With Plans]

My newest project after my corsair, this plane will be my 8th foamy homemade plane. Started with my new habit, visiting a nearby lake every saturday to play an RC boat, which also homemade. While looking the lake, I thought it will be a good spot for take off and land a seaplane, if I have one.

I choose Supermarine Walrus because it's a biplane, I love biplane and it only has 1 engine. I plan to use the same power house as my cessna 185, using 1550 kv, 9x6 prop, 20A ESC and 2200mah 3S battery so the weight will be strictly not above 1200 gram. Both wing area is 45.6 sq.dm, so with 1200 gram (42.3 oz) the wing loading will be 26 g/sq.dm (9.19 oz/sq.ft). It makes the plane very easy to airborne, like a glider, I hope

Supermarine Walrus in Action (5 min 31 sec)


This thread is a build log, the plans will be available when it successfully in the air on maiden flight.
