The idea of this event has caught my attention and I have been fooling with it on a casual basis for a bit. I had a chance to fly my plane at the Brodak meet. People at the Perky circle thought it was cool. It hits low 90's when it is 'on'. I think it would be a good addition to that affair. Also, I would like to include it in some of our own meets next year.
This brings me to the question. Why are solid lines required for this event instead of easier to use and less intimidating, for most people who might be willing to give it a try, .015 stranded lines? I'm hoping someone will be able to provide a solid reason to explain this rule. Thanks, C. T. Schaefer

There's no provision in the AMA rule book for stranded lines in a speed event. So there's the insurance to consider. I know it's not an AMA event but there's a section that explains what to do in that circumstance. Of course you know .016" solid wire is stronger than .015" stranded. You go up in size when using stranded wire (.018"?).

Solid steel lines are a Speed Category thing. Given the choice of solid or 7-strand of equal strength, the serious speed flyer would always go with the thinner solids.
So you define Fox 35 Speed as a non-Rule Book special event. Then you can use a similar Rule Book event as a safety standard. The closest Rule Book event is Slow Combat with stranded .018" x 59'-6" lines. In my opinion, you were pushing your luck with planes in the middle 90's with .015" stranded.

Is this a running half mile or a proto run?
-
Thanks for the replies. I get it. Goes for Perky too. The Fox Speed is a proto 14 laps.

i have a fox speed about 1/2 finished and would fly it next year if they have it at Brodaks

If you label the event with "Speed" in the name, I suspect AMA would look quite closely at not following the "Speed" rules. Yes, kind of silly in some cases, but those are the rules. (The Arizona guys call their Fox speed event something like "Sport Racing" or some-such in order to circumvent the AMA rules for a speed event.)
A similar complaint can be lodged about requiring wire sizes for nostalgia speed events based on the current records.

Then you have the aspect of people using their 20 year old Foxberg lines on a faster model.

When John Moll from the Lafayette Esquadrille came up with the rules he followed the speed rules which are very similar to how Perky is set up with solid lines.
The rules can be found here

I even entered a plane in the event and had never used solid lines before and had no problems. I am use to stranded lines so I asked and quickly learned how to deal with them without any problems. I normally fly CL scale models with throttle and stranded lines so this was a big change for me.
I would also encourage the Brodak contest to add Fox 35 Stunt speed to next years contest. This event has been added to contests in Ohio and the Treetown area near Chicago. In fact the Dayton CL club will have their event this coming weekend.
The best thing about this event is that ANY Fox 35 stunt powered model if allowed, it could be a ringmaster, twister or scratch built speed model like mine that hit 69 mph. Put .016 solids on a your ringmaster or similar model and you are in
The timing starts from a standing start for 14 laps

I would make a case that any event not in The Rule Book is a special event. Otherwise the Fox 35 Stunt would be subjected to the same lines and pull test as a piped OPS 40.

Amen to that

And if being used in stunt, they WOULD (properly) use the same lines if the models weighed the same!
Simple physics, Paul! n~

As with other speed and racing events, we start with today's performance and then go higher if a proven need materializes.
As of today, Nelson 36 fast combat planes are still going 130 MPH on .018" x 60' 7-strand lines. I don't believe that anything that passes for a Fox 35 Stunt will come anywhere near that.
