Richard Harris Posted July 27, 2019 Share Posted July 27, 2019 I have been asked to design a model for free flight to be powered by a Mills 75. As the intended model will be experiment with possible modifications/ crashes along the way I am reluctant to install the Mills until fully sorted. Id hate to damage the Mills so to make life easier I am thinking of going electric for the experimental stage but don't really know the kind of power output the Mills has. Can anyone recommend a suitable like for like electric set up which would use the same diameter prop as the Mills please?

Doug Campbell Posted July 27, 2019 Share Posted July 27, 2019 An original Mills is more than up to the rough and tumble of a free flight model. The lightweight gives low inertia impacts that don't cause problems. A flexible nylon prop might be useful at first. Quote Link to comment Share on other sites More sharing options...
brokenenglish Posted July 27, 2019 Share Posted July 27, 2019 Respectfully, if you're unsure of yourself to that extent, you'd be better choosing one of Vic Smeeds designs... Typically a Tomboy. Quote Link to comment Share on other sites More sharing options...
Steve Hargreaves - Moderator Posted July 27, 2019 Share Posted July 27, 2019 There was some discussion around the power of a Mills in this thread Richard which might be useful **LINK** If it helps I have an electric powered Mini Tyro which is the sort of model a Mill 0.75 might have been used in & that flies very nicely on max 60W.....I did initially have about 100W in there & it really wasn't pleasant to fly...the torque of the electric motor made it want to roll every time I opened the throttle. Torque a theoretical concept where a Mills 0.75 is concerned however so I'd venture to suggest somewhere around the 50-60W mark would be about right....

Richard Harris Posted July 27, 2019 Author Share Posted July 27, 2019 Thanks for the info gents I will have a scout about for something around the 50-60w mark Brokenenglish, ironically the Mills is in a FF Tomboy at the moment. Rich Quote Link to comment Share on other sites More sharing options...
