I am working on my 337 for the T3 tailwheel suspension on my M4 Maule. The FSDO is requesting a photo of the T3 installation on a Maule. Can anyone with the T3 installed on their Maule send me a photo of their installation. Thanks for the help.

I know of someone with an Acme Aero tailwheel, but not the T3...

If anyone is interested I've got a T3 Piper/SQ twin shock tailwheel suspension for sale, same as is shown on the airframes Alaska website only just about half price. It came off a Maule M-7.
I bought it used in a package deal with several other items. Figured I'd put it on later but couldn't get the Juneau or Anchorage FSDO's to give me a field approval without the whole engineering Sh%@-Show so its up for sale if anyone wants it. $500 +shipping and its yours.

My mechanic got the approval for mine and has done 3 or 4 more since.

Hi All,
I have a M7-235 C "Spring Gear" I was wondering how heavy the tail is, so I set the tail wheel on a bathroom scale the plane was pretty much empty, 15 gallons of gas and 10 lbs. in the baggage area. It weighed 225 lbs. Do I have a heavy tail or is that about normal?
Thanks
Gary

That’s a little hard to say, as they are usually weighed in the level flight attitude, which does change the weight distribution between main and tail wheels. Also, they are usually weighed empty. 15 gallons of gas and 10 lbs. baggage WILL add significantly to the tail weight, given the long arm. My M-6-235, completely empty, in the flight attitude, is 111 lbs. at the tailwheel.
Maybe someone else can slide a scale under their tail in the ground attitude and see what they get.

With 40 gals fuel, no occupants or baggage, my MX-7-180 weighs in at about 225 lbs at the tail wheel.

I just got an email from Alaska Gear Company about their T3 tail wheel. I didn't realize that they had one STC'd for Maules. I know that some Maule owners have them but I thought it was a field approval. Has anyone purchased the STC?

I'm happy with my ABI 3224A tail wheel and ABI tail spring but I can see where the T3 might be a good idea on really rough landing zones to reduce the stress on the tail wheel and airframe.
What do those who have flown a while with them think?

As far as I know, they will sell you a Maule one, but it isn't STC'd and is labeled experimental. At the link you posted, if you zoom in a bit on the label on the side it says experimental. The STC'd models are only PA18 and C170, but I think they are slowly working through the others. If you go to the PA18 and C170 items on their website, you will see a $250 add-on option to buy the STC.
I just installed mine this week. Had a DAR friend sign off on a field approval in December, he stipulated that I remove the sticker that said "experimental". Seems well made, that's about all I know at this point. Plan to put it through the paces this summer. It was actually right at the same weight of the steel springs I removed, so no W/B change.

Thanks Asa. It looks like there's no slack in the tail wheel steering chains that attach the steering arm to the springs with the T3. I have to keep some slack in my ABI 3224A to allow the tail wheel to move without resistance to about 30 degrees either way. There's no shimmy but I lose a little bit of steering authority on the ground. It looks like the T3 fixes that problem without shimmying.
