I started on my first dime scale.  It is pretty challenging.

For what it is worth I built a Robin from the Paul Bradley plan and am quite pleased with it. Trimming was little challenging as it seem to be hell bent on turning left quite sharply.  However with some right side thrust, a tiny gurney flap and a dab of plasticine and the benefit of a very calm day it now seems to be flying quite nicely.  Just need the turn (to the right) to be tightened up slightly to reduce the trudge to retrieve and I will be happy! There are some nice colour schemes.

David - It is nice to hear that you built a Robin from my plan and that it is performing for you.

Glad to be of service Paul.  I might even build a larger version as it is a nice little aeroplane.

Had a little time to work on it.  This thing better fly because it is kind of a pain to build!  I'm no watchmaker!

Sympathy, I'm building the Howard DGA (W12) from the nickel range and the fuselage was a right fiddle.   How on earth Comet expected 10 or 11 year old kids to be able to make a flyable model out of these baffles me.

They are a bit of a challenge but we have fun contests with them,

I had never heard the term 'nickel/nickle scale' tho I think I built a Culver Dart that size. I didn't know it was a thing!

Not sure there's really a Nickel scale; more that FAC run events based on Comet's Nickel range of models most of which are about 10" span so would (probably, maybe) qualify for Dime scale.  We're giving the idea a go at Trinity in December.

Some pictures of the wing.  I made shims out of card stock to keep everything in place.

I guess this should be in the Dime Scale forum.  I didn't see it.  Sorry.

The frame is finished.  5 1/2 grams as you see it here.  I'm going to cover it with prepared tissue.

Nice work, useless idiot! the weight is right where you want it at this point. What kind of prepared tissue are you covering with? I love the old Comet designs. The Robin has a solid reputation with no un-lady-like behavior in the reports! Good luck covering! So far so good!

Thanks.  I'm covering it with domestic (Peck) tissue that is pre-shrunk and given a coat of Krylon gloss clear.  The nose already has it because the window frame had to go on top of it.  I used cellophane in the inside of the frames.

I decided to go ahead and cover the wing bottom chord.  The tail graphics are my first attempt at printing on tissue.

I decided to wait on finishing the details to do glide tests.  Why break them off?

What you see here is 9.7 grams and I still have to balance it.

I remember building one of those, back when I could buy the kit at the store down the road.

Here is a link to the initial test glides.  It flies very well!  Right at 12g balanced to the spar.

Congratulations on producing an aerodynamically sound and beautiful plane!  I do believe that as a kid I had many rubber-powered flights that were far shorter than your glides.  Well done!

I'm calling it done.  I had to take out all of the nose weight from the glide test so it sits balanced at 17.6g without any additional weight.  I'm sure that will change.
I used a Guillow's C6 6" prop with Nason clutch (from the Bird Dog) and a 12" loop of 1/8" braided with a 12" loop of 3/32".  Never done that before.
