Wing Envy! Old Fogey Biplane.

Old Fogey - double take!

When I saw the recent article on the brilliant Anvil by kactiguy- it got me thinking about biplanes. Sadly my Baby Blender met a sticky end and is currently recycling through a number of new builds, so I wondered about building something new(ish), maybe something a little quirky....

Well here it is - the Old Fogey biplane. We do it because we can :)

Not quite a sesquiplane (bottom wing area needs to be less than 50% of original) but still quite pretty - in an ugly Old Fogey kind of way.

UPDATE - 31/08/2016 - I've been exploring the topic of Angle of Incidence more recently, both from research and from experimenting with builds. The conclusion I've come to is that for most model planes, no more than 2 degrees Angle of Incidence is required for the vast majority of more modern designs. This actually led me to reduce the 'real life' Angle of Incidence on model versions of biplanes I designed - why? Because with the 'real life' angle, the wings produced too much lift, which needed to be countered by negative inputs like; adding lots of nose weight, excessive down elevator, or a steep downward thrust angle on the motor. Basically the plane is fighting itself - one part trying to lift the plane, the other part trying to keep it level - it is a waste of battery power that could be used to keep the plane flying longer. With this version of the Old Fogey I kept the 4 degrees angle of Incidence of the original, and relied on a pile of nose weight to keep it flying level. If I had known at the time, I would have re-profiled the wing seat to reduce the A of I and flown it on the correct CG, which would have given me much better slow-flying performance. I discuss this in my recent article 'Grouchy' Old Fogey getting you down?
