Thank again for the infos, we can get the Graupner props here too from OSE(26mm and up)

I was impressed by these small bronze props, the small 3 blades look more like for scale use than racing and the other might just be Octura! The two carb too are impressive,they kind of look like Tarno(except for the blue nut). Why don't you want to have the belt stay around the flywheel for running? Most IC boats from .21 to .90 run happily that way and you just need to tuck it away before lauching which is not a big deal
