    Looking good Sparks! I had been looking at the Popsie plan with a view to building one myself. In the end I decided to build my own design based around the Popsie idea (just about ready for its first crash once the wind dies down in Warwickshire!) but am thinking of building a scaled up Popsie one of these days so will be following your blog from now on!

    Nice work John! Got a way to go on mine yet. Let us know how the maiden goes.

    Well I think I'll definitely fit some flaps to mine. I may even fit them without servos, pushrods etc but fixed in the up position so that I can try the model out without flaps and make them operable later if required. That way if I decide not to use them I won't have added much weight unnecessarily, but if I do decide to use them I won't have to retrofit them. Jim

    I have used flapperons on previous models with mixed results. They make an acceptable compromise if the only alternative is major wing surgery but I won't be using them this time - just curious to see if anyone has given it a go. Jim

    Has anyone tried using a computer radio to make the ailerons work as flapperons? Highly non-scale of course but might save the hassle of hacking into a wing to retrofit flaps. Jim

    It seems the general opinion is that flaps are all but essential on this model, so I will be incorporating them on my wing. I am going to try and keep the pushrods internal if I can. So far I am undecided about whether to use the wing lower rear spar as the starting point for the flaps or to let in another spar further aft - the existing one would result in unnecessarily large flaps. Has anyone established the pitch couple on lowering the flaps in flight? John it should be entirely possible to have flaps moving with the gear - either with the mixing facility on a computer radio or with a Y-lead on the retract servo. However, I was thinking of having three positions for my flaps - up, take-off / approach and landing and using the three position flap switch on my transmitter. Jim

    Thanks for the info John. I certainly will post some pictures once I have some pictures to post - at the moment I just have some part built components! The build is about to be slowed down considerably by the arrival of Newberry Junior! Best wishes all, Jim

    Hi All. I'm building the Nijhuis Spitfire - just got to the stage where I am about to start sheeting the undersurface of the wing (I'll be sure to remember the wing bolt reinforcement before proceeding any further!!) For info, I have decided to model the Mk IX of the BBMF when it was in 443 Sqn colours as 2-IV (although my model won't have the clipped wings as I like the iconic wingtip shape and anyway I reckon chopping useful wing area off a model is not something I want to be doing!) I am making up scale ish rudder and elevators with ribs which will be covered in Solartex to give a fabric look before painting, and the rudder has the pointier outline of the later Mk IX, as per the BBMF model. I am interested in John's use of Poly C on the fuselage - I have never come across this product before and am interested to hear a bit more about it - is the finish tough and lightweight? I have used glass cloth and polyester resin a lot in the past and will be using this on the wings - but you reckon Poly C just painted straight onto sealed wood will do the trick for the fuselage? It certainly sounds simpler than skinning the fuz with glass cloth. Jim

    Hi All, I have used Compufoil for my PC but now having moved onto a Macbook I am looking for something similar that will work on a Mac. Every programme I find on the web seems to work only with a PC. Any ideas?
