I've been looking for a way to mount a XLX2 on the center brace after reversing the motor mount and I'm too afraid to pull the trigger on any because I can't guarantee they'll fit. I've emailed a couple of the vendors but didn't get much info. I ordered an aluminum one off of eBay that had a dropdown plate for the ESC but it didn't work because of the new motor location and size. I also tried reversing it, but the servo/receiver box and motor mount in the way. I know the 1721 is a little smaller in diameter than the 2028, but I just want to be sure one will work before I spend $50-$100 on one. Does anyone know of a carbon fiber or aluminum brace that will work with this setup?
