I've been doing some research on wing mount options for the Granite. People on the forums say the Outcast 4s wing mount is a direct fit no mod needed. And then I read a post that the RPM outcast wing mount is stronger (https://www.amazon.com/dp/B01CQ2PCPC/?&tag=arrma-20). Does anyone know if the RPM one will fit the Granite? If it does then might as well get this one instead because it's also cheaper.
