My Senior is powered by a Thunder Tiger GP42. I had to add considerable nose weight, I think 3 ounces. If I were to do it again, I'd put at least a ball bearing .46 on it, a OS .55 isn't out of the question. I used to get mine in a '98 Chevy Cavalier, it's back seat folded down. I looked it up and there is way to remove the back seat on the Charger. Check Youtube. If you put ailerons on it, definitely reduce the dihedral. Also, once you build a Senior Kadet, use every available training material available if you're a newbie. That includes simulators, books and an experienced modeler you can get to help you. The Kadet is good plane, but a lot of work goes into it. Use every available training method available.
