A470 Soaring: ME - 109 Build cont.

About A470 Soaring

This is the blog for a few guys who spend their time flying radio controlled gliders, or slope soarer's, from the many and varied slopes around SE Wales.

This usually begins at the northern end of Cardiff, driving north up the A470 up to the Heads of the Valley's and the southern fringe of the Brecon Beacons. But the A470 road continues its windy way all the way to N Wales.

There are many slopes available for most wind directions, the most famous being the area between Nant-y-Moel and Treorchi known as The Bwlch, which has some of the best slopes and flying in Europe with many F3F competitions being held there each year and visited by many fliers from Europe and around the world. At 1500 feet (450m) above sea level, there is usually more wind than not, and certainly more than at sea level.

If you require any further information, are new to slope soaring or are visiting the area, please contact Steve at steve.houghton59@gmail.com . I look forward to hearing from you.

ME - 109 Build cont.

I need to add some strength back to the fuselage that I'll lose with the thinner correx, so I decided to add some stringers running down the model.

Bearing in mind that I am a cheap-skate :-) and want to keep the build cost to a minimum instead of buying carbon rod I looked around my sheds and found some strong, light weight plant support sticks which will do nicely.

I rebated the top and bottom of the formers with my Dremel type tool and hot glued the stringers in place ensuring that they were straight.

De-fluteing.

Correx sheet needs to be more flexible to allow it to bend around curves, to achieve this we 'de-flute' it.
To do this you use a hooked Stanley knife type blade and slit open the flutes on the inside surface of the correx by drawing the blade down the length of the sheet, ensuring you only cut through one side of the flute or you end up cutting the sheet in half.

Normally the plan will show you what sections you need to de-flute, but as this build plan is not intended for a correx model I have to decide as I go along where the curves are needed.
