I would like to extend the wires on a Spectrum 60 amp SRX 200 esc switch. The switch is only attached to the esc and easily detached.The wires are very thin can I just split and extend a few inches or might there be dragons?

A picture would help.

Reading your questio again and I see that a Spektrum SRX200 is actually a receiver. Presumably you have a seperate 60A speed controller which has a switch, much like this one.


As you say, the wires to the switch are very thin - typically 26AWG. Cutting them to insert an additional piece is possible, but only if you trust your soldering ability. Wire to wire joints are a pain in the proverbial!
I would suggest it's easier to pull back the cover from the switch and solder another switch and leads in parallel with it. Leave the existing switch in the OFF position and use the new one instead.

Then perhaps a mechanical extension such as a length of 18SWG piano wire through the switch toggle to act as a pushrod? No dragons there!

Thanks perhaps something like that as below deck is such a cramped space I was tempted to lengthen the Batt feed so I could move it all to the next open space

Hi, For extending wires, a much easier way is to solder seal heat shrink. you strip the ends to be joined, insert in the heat shrink fitting and heat with a hot air gun (or similar) the heat shrink closes on the wire cover and the solder ring in the fitting melts to give a good joint.

example from e-bay **LINK**

Cheers Tom

Eyup, Tom - long time since, eh?

Those gizmos are truly cunning but a trifle expensive unless you're making lots of wire-to-wire joints of different sizes. Nonetheless I've saved the link for possible future use - many thanks and HNY.

Hi Dave, A HNY,2U2.

Don't build these days, No water. Jobsworth stopped local pond, fishing only, nature reserve.

Do follow MB, but only post if I think can be useful and non controversial.

Those 'gizmos' are available in smaller quantities typical 5 off white (26-24 SWG) £1.50 p+p inc.

same source.

EP sorry for hijacking your post HNY

We welcome well written contributions from Website members on almost any aspect of Model Boating with a particular emphasis on practical hints, tips, experience and builds.

In order to maintain a consistent standard and format, all suggestions should first be sent to me by Personal Message for approval in principle. Only a very limited amount of time is available for editing contributions into a suitable format for placing on the website so it is important that the material is well presented, lucid and free from obvious spelling errors. I think it goes without saying that contributions should be illustrated by appropriate photos. I shall be happy to give advice on this.

The Member Contribution area offers space for short informative mini articles which would not normally find a place in Model Boats magazine. It is an opportunity for Website Members to freely share their  expertise and experience but I am afraid that virtue is its own reward as there is no budget to offer more material recompense!

I look forward to receiving your suggestions.
