grunau baby 11b (mark 2)

[gerryb]

hi all, i,ve been doing a bit of building lately, one of fred's grunau baby 1/4 sc semi kits to be exact.

he decided to use a different wing section on the wing for slope soaring and suggested i might build it and see see how it would work out.

as usual with fred's designs, it goes together very quickly and everything fits nicely together.

he and mario (ronan) have full build logs of the model with the original wing, so here's a few photos of mine with the new wing (spot the difference)........





fred supplies a servo tray which fits behind the cockpit floor, but i like to have my servos 'getatable', so i'll fit them here instead.



i like to build both halves of the wing at the same time, so i cut the plan and just did everything on the double.



 this is where the airbrakes will go. i'm working on them separately until i'm happy with how they work.



 this is where the a/b servo will fit. i'm using a couple of hi-tec 82mg.

more photos later, soon as i can drag myself away from the building board

As usual, flawless and clean build  :clap:

grunau is progressing nicely............


i left the rear end open until i've connected the elevator control horn...



first proper look at all the bits assembled.....


airbrakes built, painted and installed.....


and up close...


that wing really does look nice 'in the bones'....!



next up, sheet the wings and make some struts

[Fred]

WOW!  :clap:  :clap:  :clap:

Now that is looking really good! :clap:  :clap:

[gerryb]

thanks fred.

and your vimy looks the biz too!  by the way, the 2nd programme of the history of aviation is on next thursday night.  i missed the start of last night's prog,  did they show the vimy?

[Fred]

Thanks Gerry  

Recorded it, as one of the girl got sick as I was watching it  
Did not had time tonight, I'll watch it tomorrow, but the Vimy is not featured in the documentary for sure, as it was only made for the World Premiere  

But President Higgins  and the CEO of Boeing saw it  :lol: (and got some nice words about it   ) Still have to get these pages about the Vimy done  :!:

update on grunau baby.

i ran into some bother last year while working on the air brakes. clumsy fingers and fairly delicate pivot arms don't go well together.  i had the a/b's working nicely, then i dropped a screwdriver into the  a/b well and while getting it out, i broke one of the pivot arms. 'oh dear' is a polite version of what i said!!!  i tried to make new ones from birch ply which were stronger, but they were never quite right.

so the whole build ground to a halt for months until a friend of mine made me a set of arms from aluminium exactly as per the originals. problem solved.

now i was back on track,  building was resumed and in the space of a few weeks the model was finished and covered.

at the moment i'm putting on the primer coat of paint, so should be gloss coating soon.  the colour scheme is basically white with some coloured trim.  my problem has always been paint creeping under the masking tape and causing all sorts of grief.  if anyone can suggest a better type of masking tape or technique, i would be delighted to hear from you.

a few photos of the gb as it is parts of the a/b's
parts in place
parts ready for assembly
and ready for painting

That looks fantastic Ger!  :clap:  :clap:  :clap:
Just can't wait to see it finished and in the flesh  :clap:  :clap:

(on a side note, the A/B arms are in 2mm epoxy now)

[gerryb]

thanks fred, epoxy is a much better idea

Hi Ger,

I am absolutely no expert at painting, but I found that Tamiya masking tapes improved my edges  enormously. Tight curves are still a major challenge for me, but gentle curves and straight lines are now almost pleasant to mask off and paint.

Maybe someone who is better at painting can chime in here.

In case anyone is wondering - finishing models is the part of the build I dislike most, and I reckon it shows.

Chris

[gerryb]

thanks chris, appreciate that.

where can i get tamiya tape? my lines are straight, so that tape could be exactly what i need
