I have a fiberglass one, 1in diameter, lenght to be checked.

Let me know if it would be suitable for your use.

Tom,
Wold Steel be an option? Just wondering if there would be benefit, obviously you could use some ballast in that big beast.

LEN

Len,
Yes, steel is an option and I have some 1" drill stock that I can cut a rod from. I'll see where I end up weight wise and then cut one....want to stay out of the 55# inspection process.

Stéphane,
That would be great.....pm me your phone number and a good time to call and we can talk about it.

Got it. I have Tony's Petrel kit and I think that sports a 1" dia. rod too. The ASK outer tube is metric, but essentially 1 9/16.

Steve,
Didn't see this post....... That is a big tube! What's the wall thickness?

Tom, You can use 7075 aluminum from McMaster and drill the ends out where you don't need as much strength. It has a much higher yield strength than fiberglass. Also will not break just bend if you have a hard landing. I can drill it out for you if needed. Looks like 57 bucks for a 3 foot bar. I have done this on many of my planes.

here is what is in Mcmaster.

Exceptionally strong but still lightweight, this aircraft alloy has better corrosion resistance than Alloy 2024 due to the addition of zinc. Originally developed for aircraft frames, it is also used for keys, gears, and other high-stress parts. Heat treatable. Nonmagnetic. Temperature range is -320° to +212° F.

Warning! Hardness and yield strength are not guaranteed and are intended only as a basis for comparison.
Rods—Unpolished (Mill) Finish

Hardness: 150 Brinell
Yield Strength: 66,000 psi
Temper: T651

Meet ASTM B211. Straightness tolerance is not rated. Length tolerance is ±1".
