Cable soldering and protection

[Cralis]

My heli came with the wires for the Lipo alarm connected. It was a neat job. The connection seems to be covered with a plastic sleeve that has shrunk on the cable to keep it tight and compact.

My last smash managed to pull a wire out of the connection. The sleeve is still on, but, is there a way to loosen the sleev, so that I can re-attach the wire?

Nope you will have to get some new heat shrink tubing and redo it,

[Cralis]

Thanks.
What size would I need, and also, what do you need to shrink it?

[marktigere1]

Get a piece large enough to slide over the joint easily but not too large as it will not shrink enough.

I use a hair dryer to shrink it.

A heat gun is too hot IMHO.

What size is the norm for Sevo cables and power cables (Lipo to ESC)?

[marktigere1]

Depends if you have to pass the heat shrink over any large components. The stuff comes as a tube which you feed over the wires.

For a servo plug I guess its about 15mm you need.

Power cables would be smaller.

Measure your wire/component width and go from there.

Also try als hobbies that do a pack of different sizes very cheap, always come in handy

I generally find that when jointing cables the heat shrink should reduce in size (width) by about 50% given a good blast of heat. eg 10mm & below.

And try ashtek, hes reliable http://ashtekelectronics.com/shop/heatshrink-c176.html

Maplin also sell a good selection of heatshrink

I've found Ashtek Electronics to be very good for heatshrink, connectors etc, Ash turns orders around quickly too.
