A scanned copy of the STC would be much appreciated.

Sorry for the delay. Here's the scanned document. Interestingly, I am apparently missing pages 3 and 4. These presumably cover the A and B models. I don't know why that is. This is what I have in my log books from when I purchased the plane and it starts with the 1967 models. Since mine is a 1969 T337D it is covered by whats in here. I also have the original Installation and Pilots Operating Handbook supplements for the Robertson STC.

Here's a link to the FAA STC registry page which has the full text as a pdf

We have a 70 E mode, before the robertson was added it was a 4400 lb max TO weight plane. After the the robertson was incorporated the max TO weight is now 4630.

I bought a T337E, I can confirm my gross weight with the R/STOL kit is 4700 lbs (up from 4630lbs.) Landing weight is unchanged at 4400 lbs.
