There's a write up on this site or RC Groups, that I found. They used RTV silicone to help hold the pants on and make it kind of a soft mount. They claimed that they didn't have any issues. I'm going to try it on mine. If I remember correctly, they used the Robart struts. The only thing is the RTV is heavy so I would immagine that it should be used sparingly. I also can't attest to its bond holding when fuel seepage starts. I'm making mine electric so it's a non-issue for me.
Also- Download the instruction book for the STA-M from the GP web site. There are additional building tips and instructions that are not in the STA manual. I found this out by accident when I thought I was getting an STA-M instead of an STA. I would not have known otherwise. I thought the plans would be the same.
The STA-M manual calls for adding additional fiberglass and filler reinforcement around the mounting areas of the wheel pants.
