If you want true all out speed then stick with a single tuned pipe engine and do the research.
Yes you're absolutely right. Whenever 200 mph speed claims of Twin- powered speed planes (be it conventional or delta type airframe) show up here it's time for a big smile
For instance, if you look at the German Speed Cup contenders, nobody will ever use a twin-power setup. Even the inline tractor/pusher configuration is not worth a try in case of serious nitro powered speed attempts.
However, this thread rather focuses on "sport speed planes" I believe which is always an interesting topic.
