Here is the last set of pictures showing what i have done so far in terms of the vinyl. Next is to vac form the canopy and spray it (misted silver, probably) then I can balance the plane by adding weight to the nose cone.

It has been a while since my last update, and there is good reason! I have spent the past few days (yes, days) covering my Mig 7. First off, let me say that I know that my colour scheme is not very original, and I feel a bit lame for this, especially considering that I am studying design and that I consider myself a creative person. However, that being said, I chose the Red Bull scheme because I think it is one of the best and most recognizable brands of my generation. This is partly because I love adventurous and extreme sports (kite boarding). Anyway, enough blabble. Here are the pictures taken over the past 6 days (of which i spent almost all of my time covering the damn thing as best i could!)

So I have installed the servos, pushrods, battery, receiver etc. Next was the canopy. I could just use a 2l plastic bottle, but i thought it would be better to shape my own! It starts with a block of polyurethane which i will then cover with some fibreglass and smooth with bodyfiller. I will then vacuum form a canopy over this. Ive done the same thing for my previous, smaller Mig. This time, i have changed the shape slightly too.

I spent the majority of today getting the wings right. i wasnt happy with the way they turned out initially (see detail in pic) so i cut a new set, this time leaving some extra correx to trim off afterwards. I also fitted the turtle deck (which i am very happy about after I spent some time trimming and fitting it). I will upload pics of that part next time.

The new wing was made with a slightly smaller aerofoil. I have only decreased the height of the spar by 2mm. This seemed to give a much better curve over the whole skin too.

So, having built a couple of migs in the past, I decided to make a few more (as mig builders will know ). However, this time I have decided to make a few changes and adapt some of the things that I have learnt from building the migs previously. I will also mention the Mig 7 blog http://correxmig.blogspot.com/ where i have learnt a lot from Sean!

I am currently busy modifying the original plans by adding changes to better suit the aircraft for slope soaring. The list of changes seems to be never ending! Feel free to give me advice on that front... I have many changes in mind!
