MG19a STEINADLER 1/4 SCALE

Post by chris williams » 09 May 2019, 11:46

Since I injured my throwing arm some time back, my priorities have shifted to building lighter models, hence the spate of recent 5th scalies...
The recent Minimoa at 1/4 scale proved that it's possible to build a reasonably-sized model and still have a light wing loading, so my current goal is to build the Steinadler at 1/4 scale and keep her under the magic 7Kg's...
I still have the much larger version I built many years ago, but there's little chance I can self-launch her now!

The fuselage is built the old fashioned way: in two halves. This is quicker and simpler than a jig-based assembly, but you have to take steps to keep the fuselage straight...

Thank you, Martin...

Once enough of the 1.5mm planking at the front has been added to stiffen up the front of the fuselage, and the diagonals at the rear fitted for the same purpose, the half-shell can be removed from the board and the formers for the other side fitted...

Hello Chris,

Have you never try to launch her with a bungee. It is also more safely safe and no injury for yourself ;)

Did you do a plan for the big one Chris?

Patrick,
Do you know what sort of Bungee we would need for this?? Models are 10-12Kg

It would not be appropriate for our models, Pat, because we are using flat wing joiners. The acceleration would cause the wings to pull back under the ensuing forces. All is not lost: I still have the services of 'Iron'Man' Motley ;)

The small ply plates act as an interface between the 1.5mm ply planking at the front and the 0.8mm ply sheeting at the rear. The cross bracing at the rear of the fuselage is completed, and a card template used to make up the ply top decking....
