I've been looking at the Revenge 21 Off. Nice price, should be solid coming from Novarossi. Skimming this thread, I'm seeing references to special bearings available only from Nova. Does this apply to the Revenge? Try as I might, I can't find a parts listing for it. I'd like to find connecting rod number and bearing size before I pull the trigger on it. Anything else I should know? Thank you for your input.
