About this Plan

High wing cabin rubber powered duration model. 32in wingspan. Comet Kit no 3207. Padmonkey mailed in to say "the Comet Phantom Fury is not all formers complete. In the process of constructing this fine airplane I noticed no nose formers at all in the included print wood. I do not have an original kit however I can attempt to transpose the requisite formers and send them in for inclusion".

Update 03/07/2014: Replaced this plan with a copy that includes full printwood, thanks to pd1.

Quote: "Hi Steve, I saw that the printwood was incomplete for the Comet Phantom Fury. I scanned the printwood, all three sheets."

Update 04/07/2014: Replaced this plan with a clearer version, thanks to pd1.

Quote: "Hi Steve, There was some talk on a thread that the wings didn't line up correctly. I don't know if you want this but I redrew the wings and stabilizer and joined the wings for the Phantom Fury. Here's the new plan."

This was my Winter project last year after being given an ancient Comet kit. It was small enough to use the Upstairs Aircraft Assembly Area instead of the chilly basement. The fuselage wood was very heavy but also strong and it worked out well, tail feathers were another matter, plans warned against shrinking the covering but I didn't listen. When I shrunk the Doculam covering, the stab warped like a potato chip. I ended up building another with lighter but larger wood including diagonal braces, both lighter and stronger. I added another spar to the top of the wing for added stiffness, no problem with warps. The plans called for a removable tail section which I left out as too much trouble with no advantage. Comet expected you to build up a 6" prop from 1/8" printwood but I substituted a carved balsa version of 8" instead. My kit came with a 6" plastic prop but it was too small. The balsa landing gear design is weak, I had to brace it better to survive the first landings. While the model did fly well, my two loops of 1/8" rubber didn't provide enough power, plan is to add more rubber and maybe a larger prop for better performance. If I build another, I'll use 3/32" balsa instead of 1/16" and go with lighter wood, stronger and lighter.

I have built 2 of these models - one in the USA in 1988 when the kit was actually still for sale in Two Rivers Wisconsin, and another a few years later when I returned home to NZ with the plan in my luggage. I found this model to be a real floater and had many really good thermal flights with it. I was worried about the U/C and so on the first one I built it on a separate plate inset into the fuselage and rubber banded on. In practice it never moved so I built the second one as drawn. It always touched down like a feather so I had no issues. I did put diagonal bracing on the tailplane however. To prevent warps you need to ensure that the stresses on both sides of the tailplane are equal. This means both sides covering at the same tension and orientation, same water shrinking, same doping. Pin the tissue down flat, put your adhesive on the frame and offer it up to the tissue keeping the grain perfectly parallel to the lengthwise axis. Then remove it and do the same on the other side. Water shrink by spraying lightly with an airbrush and weight down at least 1/8 off the board to dry. Same process for a couple of thinned coats of non-shrink dope. You can also pin your tissue down and pre-shrink it to tame it a bit before putting it on the frame. Perfect joints also help avoid warps - filling crappy joints with glue is asking for trouble as the glue shrinks and pulls the structure. In both cases I carved an 8in prop though looking back a 9 or 10 would be even better. 4 strands of 1/8 braided was fine for calm weather flying.

Notes

* Credit field

The Credit field in the Outerzone database is designed to recognise and credit the hard work done in scanning and digitally cleaning these vintage and old timer model aircraft plans to get them into a usable format. Currently, it is also used to credit people simply for uploading the plan to a forum on the internet. Which is not quite the same thing. This will change soon. Probably.

Scaling

This model plan (like all plans on Outerzone) is supposedly scaled correctly and supposedly will print out nicely at the right size. But that doesn't always happen. If you are about to start building a model plane using this free plan, you are strongly advised to check the scaling very, very carefully before cutting any balsa wood.
