I built my STA about 4 years ago. I agree the Robart Struts are the way to go. I powered mine with an OS 91FS. It is a great flyer and is a big ***** cat in the air. I'm trying to find new wheel pants. I order a spare set two years ago and went to mount them and found out have I two right pants. Also, there is a thread somewhere in RCUNIVERSE and there is a guy who created the scale decals for it. His company is ModelGrafix out of Yisalia, CA. The decals help dress up the model.
