It's 1 pound 4 ounces or 600 grams. I don't have any footage yet but I will do when I can fly again. The flaps are surprisingly very effective actually, they really do help alot but my mechanism is already beginning to fail because I used only one servo to make the flaps work so I have quite long lengths of wire which flex quite a bit but its OK I guess. The ailerons definitly work, I'm really glad I added them but they need a lot of movement to control. I think that's because they are quite small so don't have as much effect. I haven't had a chance to use my crow brakes yet which in really proud of making work because I'm no good at that side of things with the transmitter. But yeah a good modification and a great test.
I'm gonna go ahead and plug my Instagram here for anyone to follow for more updates on this plane and my other projects :
