I just bought the 7075 Great assembly aluminum bulkheads for my brushless emaxx. Has anyone that have them have any problems with them? I searched the forums but all I could find were people linking them not really talking about them. The rear I couldnt get together. The pins were way too tight and wouldn't slide into place. I'm hoping it was just a bad bulkhead. That and a couple bolt points on the rear for the stabalizing bar wont thread into the holes. Just really wondering if anyone else has had this problem. Thanks for any info.
