the instructions are a little misleading. I'm working on my assault Raptor and things are going good. I'm following the instructions to the letter, and that's when the instructions lead me astray on installing the sensor antenna #48 I believe. If you put it where it says, you will discover that it is where the intake close to the canopy. Do not follow instructions on this step like I did! I now have to cut the antenna out gingerly and install it in the right place, below the intake. other than that, I am loving the build. I hope this helps someone in the process of their build. Find good pics for reference. I have fired off an email to Moebius to let them know.
