After much $$ consternation, I opted to go with the Grove cylinders. We've had this plane for ten years after buying it from an insurance company. The owner had flipped it over in a field and we did...

For what it's worth, I sent my mount to Kosala for overhaul and STC mod. It was right at a grand. No problem with the fit upon reinstalling.

Yes sir you are correct. I called Aviat and they sell the new Groves, direct replacement, no extra paperwork for $383.50 each. Substantially less than Grove.
Thank you for the help.

Here's a couple of pictures from the actual Kenmore STC.

Jim,
Thank you for the schematic. It really made the difference.
Here is the latest and its not good news for me. Talked with the very nice folks at Grove. They have direct replacement cylinders...

Thanks everyone. Will let ya'll know the outcome.

Good idea, thanks.

I know you guys consider anything Husky to be associated with the mark of the beast. But I was hoping for a little compassion on this one (and I own a PA-12).

The left brake is dragging on our...

Well I got to the bottom of this question. I'll be using the Gill-25 simply because I have a new one on the shelf.
I talked with a very nice and knowledgeable fellow at Gill named Tom who verified...

Hello Everyone,
The Gill G-25 battery in my Kenmore O-320 PA-12 was getting tired so I tested it and it needs replacing. Here's the question. Gills' website says their STC approved battery for...

Sir,
You are a wise man and your comments verified my reasoning. Thank you and the others for your generous input. Since I am my A&P mechanic I will take your advice. If you make it to Oshkosh next...

Good point and that is certainly true. However as long as you get accurate measurements for the ARMS you will be fine. You could actually measure it anywhere you wanted along the fuselage and get the...

Sounds like a good plan. The plane flies great. After adding the lightweight starter and oil cooler obviously I had to do a new W&B. That's when the numbers indicated I was out a little.

I agree with you on the lead shot issue. Operating from a paranoid/safety world view, I would not be comfortable with that option.
Is mounting a lead block on the tail wheel spring area...

It's total moment divided by total weight.

Gents,
I weighed my PA-12 to obtain the Empty weight C.G. last Saturday. I would like to share my numbers and of course have a couple of questions.

I purchased a new set of three AWS-2K scales...

I am currently tied up with hurricane Isaac issues.
I will weigh the airplane, take pictures icluding a level on the firewall and the horizontal tail travel (someone asked specifically for that),...

I found the screw in the upper door channel. But there is no floorboard below. Hence no "hole in the floor board".
So I'm going with the plumb bob 1.5" ahead of the main wheel axle center.
Getting...

I leveled it up today in anticipation of weighing it tomorrow at another location. I easily found the screw in the overhead door frame. But the floorboard does not extend that far back. Hence no...

John,
Thanks a lot. I really appreciate the information. I'm gonna weigh it Saturday and we'll see how it goes. Initially it appears to be somewhat tail heavy. I may be looking at moving the battery...

I read the T.C. information. After it is leveled what is the formula for computing the W&B?
Is it:

Tire weight X (1)=MMT
Tire weight X (1)=MMT
Tail wheel weight X (arm measured at center of...

Hello,
I'm gonna get my O-320 PA-12 weighed. It seems to compute as tail heavy. I've read the various posts. Most of them reference the PA-18. To ensure it is done properly:

Level Aircraft, empty...

Hello,
My PA-12 has the overhead X bracing and skylight. It also has the tab in in the rear baggage area for the rear passenger shoulder harness.
Currently both seats only have seat belts. I want...

Sounds good. Thanks.

Excellent resources, just printed them.
Thanks.
