Key words-PERSONAL USE.
You are correct, they will not go after you if it's for you own use, but the post one was about someone SELLING a model and LM WILL go after you if you try to market a LM product.
The real money for LM is not in RC, but plastic models.
All the plastic model companies, Revell, Hasegawa, etc, caved in to LM and have agreements with LM. Look on any kit box of the F-16, P-38, etc and you will see "Offically licensed by Lockheed Martin".
