Ken Willard's "Duckling" for G-Mark .030 RC - are 4 channels too many?
Hello everyone
I need some advice with my first nitro powered airplane (I just built and flown Eflite 2s-size electrics till now, like 80 g AUW)
For these winter holidays I gave myself the task to finally build something for my G-Mark .030 RC that's waiting to be used since a couple of years.
I decided to go for the Duckling, a small 25' ws seaplane (see attached files)
I would like to add ailerons.. should I then reduce the dihedral? Should I modify the wing to a double-surface design or could I just add ailerons to the original single-surface undercambered wing?
Would 4.4 - 5.5 grams servos be enough for this little bird?
Many thanks for your help!

Fun project, just the kind that I enjoy. I personally would stay with rudder control and the diehedral as designed - simplicity is nice.
However, if you do go to ailerons, I think the cambered sheet format for the wing remains fine - no need to change to a full section wing.
That servo size should be fine from a power perspective, though often the smaller servos don't do so well with vibration of glow powerplants. A 6g direction for servos might be a better option.
Have fun, and please share photos of your project along the way.
