Using an electric motor set up without the motor

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?

I've never done it but I can't see problem other than that you'll be carrying more weight than necessary.

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.

I've done the same too with no problems.

Make sure the wires to the motor can't short .

Why remove the motor? It is good insurance!

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.

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.

Many thanks to Geoff, Trevor, Steve, Frank, Anthony, David, and Cuban8.
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.

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.
