Handling is said to feel the same. The weight savings is approximately a third, but the real selling point is likely the strength, resilience and corrosion resistance. I got one in the works. Couple months out. I'll report back.
The reason for the thickness is that Ti is less tiff than steel, hence need to make Ti parts thicker to achieve same stiffness. Also- Cadmium-plated steel hardware doesn't mix with Ti. The cadmium gets into the Ti and embrittles it. Apparently, the Ti parts come with the cadmium removed, or??
So I chased down the titanium 170 tail spring at the Airmen's show. It's currently available as an owner-produced part. The PMA process appears to be a ways down the road. There's one Ti tail spring currently in use on a cub, and another on a 170. Instead of the four or five springs in a factory stack or a L-19 stack, it uses three springs, Each spring is thicker, similar to Ti main gear.
Hahaha. Too true. BTW, if anyone's interested, I hope to check out the titanium offering at the Alaska Airmen's show. I'll post any updates here. This thread has been a great use of the group feature on this site.
If anyone needed another reason, it seems like the Aero Classics you have to run with the Scott are junk anymore. Chinese-made, and I can't get more than a season or two out of them before significant weather checking occurs. Jim- Thanks for the update on the titanium tail spring.
It looks like Flight Resource has signed on as a site sponsor. If so, I'd like to thank John and company for stepping up. I've been quite happy with their customer support, and with my MT on my 170.
Gathering some cobwebs here in this group! It wasn't much of a winter for ski-flying here in interior AK- maybe that has something to do with it. I managed to log 17 hrs on skis this year, but nothing exotic enough to post about. Now the ABWs are back on, and the skis are stored for next year.
p.p.s. Within the last couple years I heard a rumor of a titanium 170 tail spring in development by The Landing Gear Works. No idea if this is for real or BS- I see it's not currently listed on their web page.
p.s.- since you are looking at replacing the tail spring- you might want to look into the L-19 spring. I've had it recommended from several trusted sources. Maybe this is what you're up to already? And I assume you know about rounding the trailing edges of the leafs, to reduce the chance of stress...
Hi Jim, Mine's a '53 170B as you may recall. I also have the 180 gear and 29" ABWs on the mains. I have a L-19 leaf spring for my tailwheel, which is a bit stouter than stock. I added a BBW at the same time that I added the 29s, replacing a standard Scott 3200. That was about 40 hours ago at the...
I recently upgraded my early-model Iridium phone to an Iridium Extreme. That's the model that has integral GPS and an SOS button. When pressed, the SOS button can automatically dial one phone...
