    Has anyone tried cutting down the propellant grain in an 18 mm D24 reload to get performance closer to the c size motors? Making a new grain adapter spacer seems easy enough. I am just wondering if anyone has experimented with something like this?

    That would make it a research motor. I have C motors by AT and that is essentially what they are but I think they have a spacer.

    If you alter them, you have to TRA level 2 and fly them at a TRA research launch or fly them on you own. It would also nullify the warrantee on the motor so I would recommend against it.
