Perky Specs

[Motorman]

What size flying wire?

Thanks,
MM

[C.T. Schaefer]

Walt, It's .014 solid. The perky rules are in the NASS site. Did you get the size yet?

[jfv]

Span is 18"

[Motorman]

How big is the tank?

[C.T. Schaefer]

3/4 oz. is good

Can you make these things profile planes?

Can you make these things profile planes?

     Ah, no. Then it wouldn't be a Perky. Check out the link below which has plans , rules and some history.  The event has been around for about ten years so there is a lot out there on the internet and old magazines that covered it. I'm sure the C/L speed SIG group would have similar info on there web site. Being a speed guy, I thought you would have looked there?

From your link:   The model has to be built to match the outline on the original plans including the wheel diameter and spinner, however the engine may be mounted inverted, upright or to the side.

So, making a profile isn't matching the outline? Don't know why it would be a problem, don't see any advantage to it.

Front view would not have the round, sort of fuselage.

    Making it a profile would not match the outline on the view of the plan from above. Basic draftsmanship and blue print reading. Mounting the engine side ways in a full fuselage is different than a profile plan form. Most participants use upright or inverted. I would have to look for photographs of anyone using a side winder mount. Engine mount/crutch gets pretty tricky, and it's a tricky little airplane to begin with.

It says "the outline" meaning one outline, doesn't say which one. Traditionally that has meant side view.

MM

The drawing was done using orthographic projection, meaning it takes at least three views to define the shape of the object.  You can split hairs all you want but nobody else seems to be having any real problems with this.

Stop being such a dork, Walt! You KNOW what the rules mean!

    Show me some kind of statement in a publication somewhere that states specifically on outlines being profile only and reference to tradition? An airplane plan is presented with three views, and that determines the shape of fuselage formers and ribs which are presented on the plan. The Perky plans show fuselage formers and wing ribs. Trying to infer anything else is just beyond silly. You spend more time trying to find ways around rules than you would if you just built something to the letter of the rule. Maybe you should try that, or do you just have problems with reading comprehension?

Ouch, you guys really know how to escalate and you put me right off of wanting to fly Perky and I had a Perky screen saver and everything. There's really only a handful of people that do this. You want to win your little arguments over all else, bravo.

Dave Edwards made a nice side mounted full fuselage Perky that showed some good speed but still needed some R&D to make a solid run.

 Wow.

 All they're trying to tell you is that it has to be a PERKY to qualify for the event. A PERKY has a full fuselage per the original design. It is this design only that qualifies for the PERKY event.
 When they say "profile" here all they are talking about is the outline of the full fuselage model when viewed from the side. Using the word "profile" in this context is very common (and proper) and in this case does not include or have anything to do with a profile model.
