I have a few of the larger old baffled piston engines. Enya 60 IIIB (the latest one), Merco 61, Merco 49 (x2), Moki M5 and my son has an OS H80. All run beautifully. I've also got a modern ABC rear exhaust engine that uses a baffled piston but that's a specialised CL stunt engine. These older engines generally are much lighter than the latest Schneurle wiz bangs
