AndyB Posted May 22, 2020 Share Posted May 22, 2020 Most machines are made for a certain prop. You can go bigger but will be more likely to snag a line with the prop on aborted take-off. Quote Link to comment Share on other sites More sharing options...

You will need to modify your re-drive unless you get a variable pitch prop and a lager hoop would be wise I would love to see someone put a 160cm prop on an Atom 80 but I'm guessing you would only be able to reverse launch with such a large hoop and it would be an expensive experiment if you couldn't get it to make sense. If life was long enough and cash was no object, I'm pretty sure I would do it just for the science Quote Link to comment Share on other sites More sharing options...

Blackburn Mark Posted June 26, 2020 Share Posted June 26, 2020 It does surprise me that we don't get any tiny engines with 160cm props I guess the benefits just don't offset the pain in the ass such a large hoop would be Quote Link to comment Share on other sites More sharing options...
