Though I have already sent this to you, this is for people who are following this thread !! like i said, will make it for maiden, if it is within these two years
Gusty's Hangar and Introduction.

A Good pilot will practice until he gets it right,
A Great pilot will practice until he can't get it wrong.

Zeroed in on the aircraft to be modeled. My model will be fashioned after N675LF that is currently wearing the pseudo colour scheme of G-ADNV.
Reasons why I choose this particular aircraft to model.
The colour scheme is interesting enough and is easy to achieve.
The full size has tail wheel, that would make my life easy in ground handling, a
The full scale does not have the anti spin strakes so do not need to model that and add weight aft of the CG.
The main wheels do sport the wheel covers with DH logo
The black colour will hide all my sins
Plenty of pictures available for reference.

Spent some time making bits and bobs for the cowl.
These included the fixing for hinge pins, and stays for the cowl cheeks. These were fabricated with few odds and ends of some brass sheet, piano wire, and screws all soldered together using soft solder (since not load bearing) and were stuck at convenient locations with a view of being more practical than scale locations (since all these would be hidden inside the cowl).
Here are a few pictures

The top and side pieces are retained by cutting out the hinge ends and fixing it with screws. To remove these three pieces just pull out the hinge pins from both sides and you are done.
Here are some more pictures this time of the stays that I fabricated to keep the cowl cheeks open. The mechanism is scale but not the location I have chosen on my model.

My sadness at not being to afford the Masala apart, somewhere in these threads there's a video of Gusty flying my Tiger Moth in rolling circles...

Sir Geoffrey De Haviland would be rolling in his grave at the thought of the Tiger Moth doing rolling circles    :-\

Hi all I don't know the image is in this post or not, if not how on earth do get images on this site. If it is there then it is of my falcon model tiger moth.

Ha it worked. I thought this blog had dried up  a while ago but am glad to see it's still going thanks to a mention by Hamish on Peterf's blog. I'm hoping to maiden it this weekend weather permitting.

It works Ron. And I am getting back to the build. Thanks for posting picture of your lovely Tiggie

@flyingboxcar,
Sir,
Got curious after exchanging a few PMs with you.
Went to page 1. June 2011.
There's all sorts of fantastic stuff!
Not going to sell my Dynam Tiger Moth anymore.
And maybe start my Goldberg Anniversary Piper Cub, pending since 1996
And i read your correspondence with a potential buyer of one of the books that you are giving away to the raddi wallah...
And the only guys i saw with 3 stars in my J&K tenure were Lutes (Lt. Generals!)
Hope to meet some day.
Regards.

flyingboxcar

Iyer sir those guys have three stars on the vehicle not on their shoulders. My three were on the shoulders  ;D

Thank you flyingboxcar, my family have banned me from flying it as I am a rubbish pilot, so a friend will maiden it but I will fly at some stage over the weekend. Sorry Manish I wrote Hamish.

Happy to let the forum members know that Ron and his Tiger won the trophy .
Here is a picture of him with the Tiggy and the silver. Sorry Ron had to post this for all to see and appreciate your hard work and accomplishment. Hope you do not mind

Thank you flyingboxcar, not at all, I hope it gives people the inspiration to keep up the momentum of their builds. The competition was the annual South eastern BMFA scratch scale build. Fortunately for me DonCoe could not fly his wonderful Bleriot because of the wind. At the moment I have taken the engine out because of an oil leak from the rocker cover gasket, should have done it earlier so now the engine bay is covered in black gunk, heyho.
Keep gluing.

It's amazing how small little items can eat up so much of time. Have been slowly chipping away on the fuse and things are getting closed.
The fairings on the undercarriage legs are all done, will do some filling and sanding to fair in the wood pieces more cleanly. Made the control cables for elevators, all working nice, worked on the dash, since the chosen F/s has a wooden dash replicating it with ply. In hind sight the Mahogany veneer I had would have been much better in terms of aesthetics, but may be that would go in some other model. Working on closing the luggage compartment, but need to wait for covering to arrive. Initial plan was to use neutral solar tex and then paint it over.
But that is now changed. Have ordered some vintage red for the fuse and silver for the surfaces. That way hopefully it would take less amount of paint to fill the weave.
Will post some pictures ASAP :)

sounds like your getting to the more interesting bits. Yes I went through a huge amount of paint because I used natural solatex but that is because if I had used silver solatex I would have to try and match the colour on all the other bits like underneath and the engine cowl, rib tapes and wing inspection covers.

@ront2384,
Sir,
Lovely!
Far better than i could manage, after 50 years in this hobby.
Eagerly await flyingboxcar's Maiden...
(While i look through the older posts in this thread...)
Regards

Thanks Ron, that confirms my assumption that natural fabric would have taken more paint.
I would use vintage red on fuse and silver on all flying surfaces. The fuse has black as well and I am assuming that black paint should cover well over the red Solartex. I would also use silver paint to paint over the flying surfaces and rest of the fuse with red or black as appropriate so that there is a degree of fill on the weave and also grime proofing, plus the biggest advantage would be to seal all the edges.
As for tapes, inspection covers etc, I have procured these from MRM but all these are in Vintage Solartex which when painted may stand out, (pity MRM do not do other colours unless you send them the material) hence I have been toying with idea of ordering from pinkit who do the tapes and inspection covers in various colours.
Some tapes in red, and rest in silver plus the inspection patches in silver should do the job.

Did you use rings under the inspection patches? How did you cut them and what material?

Another bit done on the Tiggy. Hopefully that would keep my and readers of this thread interest alive.
The first bit of covering has gone on the airframe. Since the tail feather were complete, I covered them up with silver solartex. These are now sealed in poly bags and kept away from build area to avoid any damage. Awaiting some silver pinked edge and perimeter tapes, that would enable me to apply stitching and pinked tapes on the all  the ribs and then the perimeter tape all around.
Here are some pictures.
If you would notice the Fin even has torn Egyptian tape wrapped around the fin post  ;D

The undercarriage fairing etc were completed a bit earlier, here you can see the main leg has fairing covered with litho sheet and the remaining struts are faired with balsa and attached using Gorilla glue. The next task is to apply some clear lacquer to seal the wood and then some primer, give it all a good sand ready to receive paint

Also to keep my own interest alive worked some on the instrument panel, work is still in progress. Also added is a shot of full size panel for comparision

Since the piano hinge needed to be glued on to the luggage hatch door, I needed to cover it and then glue on the hinge. Added  few screws for security but only to realize the full size I am modelling does not show any, These would be later removed and the voids covered over with perimeter tape. Yes that is the shade of red that is going on the model

Here is a picture of the control cable runs for the elevator. The link rod is from 1/8 brass rod that was filed flat at ends, drilled and all sharp edges and burrs removed. Following the full size practice the cable is also scale (1/32, 7x7 strands steel and). Had also procured some thimbles thinking they might be fit for the purpose, but alas they were too big so omitted.
