David Ramsden Posted July 1, 2020 Share Posted July 1, 2020 This might sound silly (I'm new to this). I'm creating a normal motor/esc/bec/lipo set up in a glider. I've built interchangeable noses - one with a motor and one without. Question is, when I remove the motor and head off to the slope to enjoy some silent flight, will the esc and lipo be happy just powering the receiver via the bec lead? Thanks, David Quote Link to comment Share on other sites More sharing options...
Geoff S Posted July 1, 2020 Share Posted July 1, 2020 I've never done it but I can't see problem other than that you'll be carrying more weight than necessary. Geoff Quote Link to comment Share on other sites More sharing options...
trevor wood 2 Posted July 1, 2020 Share Posted July 1, 2020 I've got a couple of 2 metre gliders where the Rx and servos are powered by a 2s lipo fed through the BEC of an old brushed ESC. They've flown for 2 or 3 years without problem I can't see weight being an issue on your installation as you will have to instal some church roof to sort out your CG when the motor is removed.

Steve Colman Posted July 1, 2020 Share Posted July 1, 2020 I've done the same too with no problems. Quote Link to comment Share on other sites More sharing options...
Frank Skilbeck Posted July 1, 2020 Share Posted July 1, 2020 Make sure the wires to the motor can't short . Quote Link to comment Share on other sites More sharing options...
Anthony Scott 2 Posted July 1, 2020 Share Posted July 1, 2020 Why remove the motor? It is good insurance! Quote Link to comment Share on other sites More sharing options...
David Hall 9 Posted July 1, 2020 Share Posted July 1, 2020 As already suggested, provided the open leads can't short, it'll be OK. This is the way I bench test radio gear, all hooked up but without a motor. Quote Link to comment Share on other sites More sharing options...
Cuban8 Posted July 1, 2020 Share Posted July 1, 2020 How about keeping it simple? Disable the motor by disconnecting it via suitable connectors (will have to be done anyway, with a detachable nosecone) and then use a rubber band to hold a folding prop closed tight to the fuz, or if a fixed prop, just take it off and replace the spinner with a suitable spacer? This is usually sufficient to satisfy the requirements of most silent flight only sites, but I have heard that some will pedantically insist on a complete no power rule even if the installation is totally disabled.

David Ramsden Posted July 2, 2020 Author Share Posted July 2, 2020 Many thanks to Geoff, Trevor, Steve, Frank, Anthony, David, and Cuban8. The reason I made an alternative nose is that I don't want to risk damage to a £40 motor if I'm not using it. My local slopes are 'Tors' topped with massive lumps of granite. The change over is just two screws and the non-motor nose is weighted to match the weight of the motor. Good point about insulating the motor leads! I might not have thought of that. Cheers, David PS I tried to add an image to this post using 'Insert image from album' but it doesn't allow me to browse my folders. Shame.

PatMc Posted July 2, 2020 Share Posted July 2, 2020 David, I don't think that you have created an album. There should be "n photos" under the number of forum posts you've made if you had. Have a look at this thread that explains creating an album. Quote Link to comment Share on other sites More sharing options...
