I've not managed much this week. My shift pattern changes have really buggered everything up; modelling and drinking wise! I should get a bit more done later, with any luck. I have to sort out the motor mounting and cowl separation before I can get much further. The kit supplied TE stock is not great, so I'll be stripping my own and I've made a tool to cut the rib notches in said TE to a constant depth.

Back soon,

Dan.

Bit more done today. Motor mounting now sorted and the beginnings of the removable magnet retained cowl. I've built in about 3 degrees down and sidethrust, so I'm hoping that should be about right. The nose taper conforms to the plan, but it ends up a bit narrower at the noseblock. Dunno what's going on there, but I should be ok as long as no judges read this...

Cheers,

Dan.

Bit more done today. Both wing panels are now built. The complete uncovered airframe, u/c and wheels and GM300 (without tank as yet!) add up to 62g. There is quite a lot of material to be sanded off, so I'm quite pleased with the weight so far.

Ta! There is a not-so-deliberate mistake in the pic. Anyone seen it yet??

Wing rib without lightening holes is different left to right......

......and leading edge is (possibly) a little bit blunt.

Good looking build, Dan.

Yep! I stuffed up the strut mounting ribs. A bit of water loosened the aliphatic joints and all is well again. Thankfully, I don't use cyano...

Removable cowl sorted, apart from fitting the retaining magnets. Just the wing strut mountings to sort (now the ribs are both in the right place...!) and it's nearly covering time.

Dan.

Not much major progress to report, but a lot of the fiddly little bits done. I decided to cover most of the internal cabin framing with tissue, so that not too much bare balsa would be visible through the glazing. That should be the definition of "Fiddly" next time they update the OED! Cowl is covered and a coat of paint on the u/c wire. Last major job before covering is set the dihedral and finish the wing tongue boxes.

All good fun!

Managed a bit more before going back to work tonight. Complete airframe with motor installation, prop, u/c and wheels is just over 90g. Just the covering and the wing struts to go on top of that, so it should turn out reasonably light.

Cheers,

Dan.

The tissue covering on the cabin framing sets it off Dan. That was worth the trouble.

Ooh, that looks nice Dan!

I have one of these skulking in the loft, it might just get promoted up the list...

Cheers all! This is what it SHOULD look like... I can't decide to do it with the unpainted cs/root fairings or not!

Both wing panels now covered, so the big shrink starts tomorrow! That means I can leave all the flying surfaces pinned down flat for as long as possible whilst the final bits on the fuselage are done. Dummy engine, markings, glazing etc.

Back soon,

Dan.

Looks great Dan.

I quite like the 'grey' centre-section: it sets off all the red, goes with the black bits, and makes it a slightly more distinctive.

One thing is annoying me. The wing struts are shown as 1/16th on the plan, which must be adhered to for Kit Scale. In my (Brief!) career as an aircraft restorer, I stripped and refinished a few Cubs and the struts are NOT 3/4" thick. More like 2". 1/16th would just look silly. Dilemma!

Dan.

Red suits it Dan - looks great. It might be worth losing points for a bit more realism perhaps? 1/16 struts would also be a bit fragile at that size anyway probably.

Aren't the struts detachable on that design?  In which case make two sets?

I think I'm too bone idle to make 2 sets! Might compromise on 3/32"...

Gotta love a Cub!

Years back someone I knew who was a bit of a maverick claimed he often incorporated a deliberate mistake in his scale models on the basis that it would distract the judges atention from others.  Never had any evidence it worked. That I could tell.
