RE: Looking for a Ripmax Alienator GP ..
Gistwj,
I have an Alienator GP NIB kit sitting in my shop. Had no idea people liked them so much. I had actually been thinking of selling mine!
I picked it up some time ago (at a bit more than $29!) to use it for my Magnum 15XL. I even purchased new mini BB servos for it, Somehow I've been busy building large gassers and little indoor electrics, so I never got around to it.
Sounds like it might be best with a bit more power than a ball bearing 15? What kind of .15 did you originally have in yours?
