Made a good start due to the poor weather.

I'll be using the laser cut parts and going electric as I don't have anything IC that small! Plus I have the motor and ESC left over from my BH Speed Air so I might as well use the bits up.

Fuselage under construction and other sections of wings being CA'ed.

That looks a great start Chris.

Slow progress as I have been doing other modelling and non modelling bits and bobs.

Got stuck with wing ribs as near the centre section as I have too many ribs and did not realise the importance of which one goes where.

Lesson 1 - make all the ribs are in the right place for aileron plate and wing root for joining

On to the fuselage and I thought I would dry fit all the way back to the tail. Its not clear to me how the stringers all converge on various ply formers. I'll post photos on the main MB forum thread.

Back to the wing tonight and after LPP suggestion that the centre line for the wing on the plan was in the wrong place and a few checks by me I was happy to glue it together.


I need to make a couple of 36mm wingtip blocks to get the 3 degrees of dihedral and I should have the basis wing structure finished.

I seem to be a bit confused with the rear fuselage so there might be a few questions for the main forum blush

Making progress

Joined the wings and continued with the front and middle of the fuselage



+ the pilot tested the suitability of the cockpit for size

Good progress with odd bits here and there over the last few days including:

  • Front cowl
  • F2 to instrument panel
  • Rear longorons glued
  • Rear fuselage infill sections
  • Wing LE and TE strips

Looking quite nice, just hope it is!


Had a bit of success with the electric motor mount as I didn't like the look of long studs (nothing wrong) just I remembered I had a couple of "spare" motor extension boxes from ARTF ic models. Completely justified storing a shed full of bits and now I have used a part! Photo to be sent once I get to the shed again.



Do I just glue the rear fuselage together construct the tail and sandwich it (seem logical to me), just can't tell on the drawings?

Is it better to shape the things like the top rear fuselage capping and then glue or glue the square and shape in-situ?

Hi Percy,

Tony's looks like this and I was wondering if its easier on or off the model to get the shape?

Apologies for a poor quality photo

PS - I have found a photo of the rear fuselage, so that's sorted.

I glued it to the model and then shaped it. Still to sand a bit yet, but i found that easier than if it was loose.

Cheers Tony,

Looks like gluing and shaping tomorrow then

PS I used a motor mount that was spare from an ARTF kit ...just need to find my ESC I have left somewhere!

As someone else said, that is a solid motor mount!

Update time even if it just a couple of small things!

Centre section of the wing progressing and a bit more of the front fuselage done.

Servos have turned up (thought I had enough, but a couple short...the expense!)



If anyone has finished the back of the wing mounting holes etc a photo would assist.

Not a lot of progress due to distractions, but that's my fault frown

Making a start in the rear end


and rudder

hi Chris, I have started on the wings and would ask what size of block did you put under the ends to get the correct dihedral? would save me calculating It and getting it wrong lol.

Will do once I get home as I didn't record what I did. Don't forget to use your washout blocks when you are gluing the wings together so as to the dihedral and the washout.

Still need to work out how I the do it again upside down when sheeting the wings, as that apparently stops the tristing in the future!

I glued one with the dihedral braces and let it set. Then glued the other tipped up.

Not saying I am right, but here's my logic!

Wing length (mine was a bit shorter as I mistook the drawing centre line crying) is 687mm at 3 degrees

Using a web calculator it comes up with 36mm (not forgetting your washout block!) so lay one wing flat and set the other on 72mm (dihedral for both wings!) blocks.... still not forgetting your washout block!

Hope that helps...or just ask away smiley

Thanks chris, so if l understand one wing flat with 6mm block under the end of the last former, other end 72mm in the air but the trailing edge 78mm to allow washout. Then sheet to allow this little distorsion to stay in the wing.

If you do it the normal way can join them, but not sheet the underside!

Lifting the horizontal wing 78mm and upside down would mean you could join and sheet..too complicated for me.

Once joined I was going to invert the wing by 38mm in the middle. Pack the LE up 6mm. Pin it all to the building board and sheet away blush

PS there is probably a much easier way to do this...someone chip in, thanks
