Hi fieldmarshall So can you give us reference pictures on your site ( meaning the RPF ) or on here to determine what power cylinders were used on what blaster and why you offer so many variables ... I'm having a hard time tracking down information thru the RPF ... If you posted more information on replicas it would make it a lot more easier for us to determine what piece to buy for the build and help with the guess work for new prop enthusiast for future builds ... As always your topnotch in my book when it comes to true replica production Thanks, Darrell Sent from my SM-N960U using Tapatalk
