Default You know that 'itch' you get when not building ?

Well I have boxes of stuff ... motors, servos, all sorts of rubbish ... you know what I mean. Lot of it - you know will not get used - but occasionally you come across something that might just fit the bill ...

I was scrolling through my plans archive .......... loads more than I will ever build ... and thought ... Duckling ... that's a nice little job. Then I thought - I need to convert from balsa to depron ... then it hit me ... the spin off model is the Micro Drake ...

So that is what I decided to do ... 3ch only - RET ... 6mm Depron ..... simplify wherever possible ...

Plan shows a curved sheet wing ... well I thought about it and decided to create depron ribs to the same form and then create a full flat bottom wing.

3mm bottom sheet flat with 6mm ribs and then 6mm sheet formed over the top to create the wing. I know that seems wrong way round - but I wanted the curved form of the 6mm to give the strength so I would not need spars. It worked a treat. Dihedral is by eye but generous !

Span is increased to 800mm, LOA to 600mm

I plan to use either a EMax 2805 2S motor with 7" prop or the Donkey 2204 3S motor with 6" prop. Idea to keep LiPo down in the small size ....

Depending on what power level she has on final ... I may add wheels to give choice of water or hard surface take-offs. The wheels I reckon can be fitted with axle flush to bottom and freewheel in the water ...



Here's build so far ...

I know exactly what you mean about "the Itch", I get it. My stockpiles in pics.
You ever build the undercarriage for this? Magnets or velcro might work a treat.
