Build of an old Graupner Eurofighter

[Roberto Gava]

Last week I received from RCTecnic the motor, esc and basic things to start building this plane.

Is an old Graupner kit designed for a .25 IC engine in front with propeller.

I've decided to make it electric to keep propeller, but allow a much cleaner nose without cylinder head and muffler on the side.

I hope next weekend I'll start building it.

Here some pictures of the plane and materials.

 

Out of the box

 

Propulsion system (except the batteries, I'll buy a couple of 3700mA 4S LiPo)

 

Detail of the motor (equivalent to a .32 2T glow)

 

Last picture for today, the ESC.

 

Y choose the battery-motor-ESC-Propellers combination to have the same weight as the OS .25 FSR + Full deposit + gas servo + receiver battery and to have a similar power as a .32 glow engine.

I hope it will be enough.

If you have any comment that could help me, please don't hesitate to make it.

Advance will be slow because I only have some time on weekends.

Seems a good plan Roberto

[Roberto Gava]

Thanks Timbo.

This Sunday I'll upload some pics of the progress on it.

I just have some hours to work every weekend.

Today I just started the build.
Before the Eurofighter I advanced with the reparation of the Olympic.

Now some pictures of it!

Foam beads joined to support the but join of the wing halves.

 

Testing the join prior to put glue.

 

I decided to use white glue.

 

Wings glued together.

 

Some weigth to fix them in place.

I've been doing a few advances on it.
During the week, I glued the nose and tailboom structures on plywood.
Now I have to glue them over the wings.
Tomorrow I'll put some pics of them.
I'm stuck with a doubt on the instructions (they are only in German), so I posted in a German Forum asking for help. I hope soon it will be solved.
Does anyone here can help me with the German translation?

Hello again.
I'm here with more pictures of the build.

Nose structure, glued with ciano, presented over the wings to verify the alignment before gluing it.

Same with the tailboom structure.

Both structures glued to the wings with white glue.

Now, according to the instructions, it's time to start with the cockpit.
I think it is to take profit of the waiting to the white glue curing time.

 

In fact, it is different to the real one. I found this picture on the net.

I still don't know if I will work on a new one more similar to the real one.
I think I will do it first with this one to test its flying characteristics.
