Ultra Micro Sopwith F.1 Camel
I recently and with much regret, decided to put my first attempt of a micro Bf109 in moulded depron onto the shelf for the time being as I was having a hard time keeping it in the air. More down to my lack of flight experience with this type of bird than the plane itself I may add but I thought I should take a step back in one sense and try something a little more docile (I know - a camel isnt exactly the best choice with it's ultra short nose) while tackling a more complex build and pushing my depron manipulation skills further in the process.
Using the plaster mould method I used for the 109 I set about creating the moulds. This time however I had got hold of some 3mm Depron Aero - a lighter weight Depron if their could be such a thing & I wanted to test it out to see how it performed and see if more weight could be saved with little or no degredation of quality.
The other thing I was banking on was the expansion properties of Depron as the wings were 4.5mm at their thickest point so the depron would need to 'grow' between the male & female mould to produce a scale aerofoil.
I used a very hard plaster this time (Crystacast) with a liquid polymer added for extra strength. On advice gained in the forum chats I also washed the moulds in diluted epoxy resin before using them - UREEKA - I still have all of them and each is still in one piece. This made me a very happy man
It took a while to strike the right temperatures for the moulds and plenty of wax release agent between presses too but I got what I wanted - the upper & lower wings, port & starb'd fuselage halves and the tail feathers too. Not perfect by an means but acceptable and worthy of a build.
So currently in the few moments I do get, I am slowly piecing together the Camel, just completed the U/C and am currently working on the struts.
This will be a slow build from here as I have a number of commitment to fulfill but I thought I would take the opportunity to get down the progress so far.
All the components unassembled on the scale including the brick, motor & battery come to 13g, so with control rods, paint, rigging and other scale details this will climb a little more no doubt!
