Wonwings diary-The trials and tribulations of a model Spitfire.
The model of the Spitfire that was scrapped off the other day has quite a bit of history attached to it,not good history but the trials and tribulations of getting her flying,this is how it started with her,a story in itself-
When I had the model shop one of my neighbouring shops was a furniture restorer and dealer,one day he came in the shop and said that he had been offered some furniture,but the stipulation was that he had to clear the house of everything that was in it,the thing was he had discovered some model aircraft parts and things in the loft,would I like to come and see what was there,and if possible make an offer to defray the costs of his furniture,yes there was method in his madness ! I went along and we climbed into a very dusty loft,in the corner was a big box of balsa wood and plans and things,next to it was a very forlorn looking Spitfire not in the best of condition and covered in dust and cobwebs,we dragged the bits out and I offered him a twenty pound note which he accepted gladly,quite honestly I did it out of a favour more than anything as there was not much in the box,just brittle old balsa wood and a few old Aeromodeller magazines.
The Spitfire looked like a Mick Reeves kit,it had been badly built out of the wrong grade of wood,the softest timber that you have ever set eyes on,it lay in the corner of my workshop for three years before I even touched it,one day I decided to see if she could be finished off,I tackled the missing tail first,then fitted a set of undercarriage legs,made some engine bearers from beech,and sheeted the wings with sixteenth balsa,the whole lot was sanded down,the grain sealed and covered in heavyweight tissue to seal the grain and knit everything together,I fitted an MDS 61 a brand motor purchased for the model,fitted servos and modified the aileron links so a servo would drive each aileron via a Y-lead,at this stage I deided not to paint her until after the test flying.
After waiting for some decent weather I took her out,ran the motor anf after numerous pre-flight checks opened up the throttle,she was a right shopping trolley to steer on the ground and I decided to do a few fast runs across the strip first before committing to flight,after a few such runs it was time to get her airborne,she took up most of the strip but climbed away in a rather nose high attitude,I got her up high and let her settle into a cruise the nose was still alarmingly high,I decided to get her down and see what was wrong ? after lining her up and keeping plenty of power on she touched the ground but there was a resounding 'crack' as the back broke just aft of the cockpit,the landing was not heavy and what had happened was the brittle soft balsa had given up the ghost,she looked a very sorry sight and I dismantled the wings from what was left of the fuselage and went home,if you fly model aircraft then you must always be in for the occasional disappointment,just go back to the workshop and assess the damage,in this case more pressing tasks were ahead of me and the broken Spitfire was relegated to the back of the workshop until I could find the time to repair her.
Another year passed by ( as they do ) and out she came again,this time I removed all of the fuselage skin in order to splice together the two broken halves,this time I managed to incorporate some medium grade wood especially where the wing joined the fuselage,it was a very fiddly task done over a period of weeks,I made a simple jig to make sure that everthing was in alignment working slowly,the job was finished and on went the wing again,after checking the centre of gravity it seemed that I had flown her somewhat tail heavy on her first flight,this was rectified by adding a metal weight from a set of old Avery scales,quite a lump but I needed it to get the c of g right,all of the weight on this model was wrong due to a poor choice of timber,the light stuff was used on the nose,and it would have been more beneficial to use heavy wood rather than the lump of ballast that I needed to add which added no structural strength whatsoever.
So after a lot of extra work she was ready once more for the air,did it go well this time ? well you will have to wait and see until tomorrow when I will continue the saga of this Spit.
