alan_k Posted September 20, 2009 Share Posted September 20, 2009 You're mad Pete yes, but I like the idea. Was it prompted by the twin prop electric motor How are you going to keep the two props rotating at the same speed throughout the rev range, or is that one of the questions one does't ask Good luck, Alan Quote Link to comment Share on other sites More sharing options...
learner_driver Posted September 20, 2009 Share Posted September 20, 2009 a truly fabulous Idea, interesting cage setup, similar to a pair of boobs probably which are always a welcome sight. Quote Link to comment Share on other sites More sharing options...
pete_b Posted September 20, 2009 Author Share Posted September 20, 2009 a truly fabulous Idea, interesting cage setup, similar to a pair of boobs probably which are always a welcome sight. Normal cage with the second prop being driven through the original drive that has been drilled out to allow a shaft to go through which will be driven by the second engine being put in the frame backwards Quote Link to comment Share on other sites More sharing options...
fanman Posted September 20, 2009 Share Posted September 20, 2009 Contra-rotating props has been done before with a single Top80. There is/was a youtube video. Guy ditched it in the end as it wasn't worth the complexity. 2 engines just makes it 4 times more complex. Quote Link to comment Share on other sites More sharing options...
