Does anyone have a source for CF Tail Booms?

Also, if you do not care if your tail-booms are not tapered, ebay has vendors that sell nice booms that are about .6" in diameter and 34" long, weighing .5 oz. per foot.

Just got one last week from Kennedy Composites , roughly measures 1 1/4 to 9/16 x 36 . It's just about a drop in fit for a Grand Esprit .

If you are using a fishing rod for a tail boom you need to be sure that it is stiff enough to do the job. Excessive flexibility will result in a lack of control. If it flops at all it is not stiff enough. In my case it was terminal. Straight in from 30 feet up.

Fishing poles are meant to bend in a controlled way. Tail booms are not

Before you get too far, I have several cheapo fishing poles that don't 'bend in a controlled way'. Many of them easily support large loads without deflection, and most pole bases seem like they would make a great boom. I think you are talking about fishing rods, a totally different construction, and I would not recommend using most fishing rods as booms.

Poles have large diameter, thin-wall base sections; the tip sections are generally useless. Poles are usually very cheap too. Rods are smaller diameter, thicker walled, and have a very short base section; more like floppy golf-club shafts. For that matter, golf shafts are regularly recommended as booms, yet they bend more than pole base sections do.

[And yes, Mark is not the only one using the terms interchangeably. But there is a difference between poles and rods, and that makes a huge difference in the deflection.]

Strange. I used t make custom fishing poles and I never saw a supplier of blanks designate a difference in terms. Kind of like a soda and pop in different places in the US?

My point was that using a part made for the job at hand has it's advantages.

Dunno what kind of fishing stuff you made, but there's a maker near here who'd rather be shot than get caught calling a fly rod a pole. It's not a pop-vs-soda thing since pop and soda are the same; it's more like rifle-vs-gun, and you can ask any Marine if you don't understand. Rods aren't made to collapse while poles are made to telescope like old antennas. Huge difference.

It's true that using a part 'made for the job' is almost always better . . . and more expensive. The pole below is fiberglass and is very stiff, the base is way overkill for a 3M sailplane but the 2nd, 3rd, or even 4th section would be appropriate. The whole pole was under $15 at the local fishing store —even Walmart carries the 12 foot poles— and you get a range of diameter (and stiffness) choices.

Extra bonus from fishing stores: kevlar thread used for fly-tying in undyed-yellow and in black, also thread wrapping holders so the stuff doesn't flop all over the place. Double bonus on poles at the end of the season: you can often find poles with damaged tip or end sections and get the rest —the larger and usable lower sections— for chump-change to save the store the time of writing off the damage and shipping back to the manufacturer.

Nothing wrong with buying the very best if you can afford it, especially for competition. But for hobbyists who need to cut costs, fishing poles are a capable, cost-effective alternative.

Re Poles Rods

I have some of these poles here as well that jc patrick describes and would not hesitate to use them as a tail boom
They are very stiff, so for those hobbiest out there that are trying to save money, go for it.
