Comet R.O.G. and Phantom Flash — Indoor Model Aircraft

GET READY HAFFA MEMBERS!

comet ROG orangeThe COMET R.O.G. is a brand new event for
HAFFA’s Seasonal Indoor Flying Contest.

AND FOR SOME OF YOU NEW TO THE HOBBY,
the PHANTOM FLASH is a MUST BUILD for the 2018/19 SEASON!

Both planes are Vintage Designs from the 20s and 30’s.

Phantom Flash Full Kit from Retro RC

I personally recommend the full kit version that is available from RetroRC.com because of all the extras you get in this deal. According to the kits description, these items are included:

Esaki tissue (red, blue, yellow, orange, black or white) is supplied pre-printed with the skull & cross-bones, a 6″ prop and bearings, enough FAI Super Sport rubber to get flying and stainless steel wire for prop shaft, wheel axles and motor hook are all provided in the kit.

 Here is the link to the Kit on the Retro RC website:  Phantom Flash ROG – 16″ span

On the other Hand, there are no available kits available at this time for the Comet R.O.G. This model aircraft must be “Scratch” built. Not a big deal for experienced builders, but for those new to the hobby—Where does one begin?

To start out we are providing here a drawing of the model in PDF form of the model commonly referred to as the Comet ROG. The Comet Models Company in 1940, called it the ADVANCED R.O.G.

Click HERE or click on the drawing below to access the PDF.

Depending on your printers capabilities or your version of Adobe Acrobat you may or may not be able to print the drawing out at actual size. You need a version higher than 9 for Acrobat to offer a tiling option to print the file with a number of “tiles” you then piece together. One option is to have a FedEx or Kinko’s take a copy of the file placed on your thumb drive and print the file at actual size. They should know how to do this.

Once you have the original drawing you can plan on how to build your model. The author built the airplane per the drawing and decided to make available changes and tips he came up with that dealt with the shortcomings of the original 1940’s design. These are in the form of Supplimental Drawings that comprise the rest of this page.

Again these are in PDF format and are 8.5″x 11″ so no tiling is needed.

The first of these Supplemental pages deals with making a saddle for the wing mount in lieu of using the wires the drawing calls out.

This Drawing features a Wing Saddle to be used instead of the original Wing Mount Design that uses wires to grip the stick fuselage, and according to the author, Jeff Nisley, it doesn’t work so well.  Our HAFFA official rules now allow a Saddle to be used. Also included is a True size Landing Gear for the R.O.G. and a handy tip to accurately bend it. 

The next two PDF file links are to 4 more pages  of Additional Information and Tips that I believe will be helpful in building and flying  the R.OG.  I know it’s confusing, but the files I had ended up so large  I had to split it up this way to make it work. Bear with me…

Make sure when you go to print these pages, your printer settings are not set to “Actual Size and not to “Fit to Printable Area” or something to that effect.

Not doing so will make the measurements out of true scale. In my case using an HP printer, my setting was Page Scaling: None.

In the first drawing above, the wire drawing to the right should be exactly 9-1/2″.

Good Luck. —Jeff Nisley—
