Sorry guys to be a pain need some advice. Saw a post which recommended these motors for the Severn so I got onto Action. Copy of what I sent:
Dear Kyje, My build is progressing and am at that stage where I need to place an order with you guys for the Speedline 1/12 Severn as per the first link dijkstra. I have got the main drive motors which are Giant Shark 50 55-400kv brushless outrunners. To drive these I would need 2 70a ESC..could you supply these? I am not very good at electronics and would have to be guided by you. What batteries would you recommend do these have to be lippo and if so what voltage? Would you also be able to supply all items shown in the link plus cabling etc. I would also need all the batteries as recommended by you. I would like to one stop shop for all items ..less of course the obvious such as lights etc. In terms of the sound system this is fine but I also need a system to record radio chatter? The speakers ideally instead of the single speaker would it be possible to supply 2 smaller units which I could fit better? Please advise listing with all items you can provide plus cabling batteries etc and price so that I can arrange payment. Thanks Regards Robin Smith From: Kyje [

Hi Robin,
The motors may be different but a good start would be to take a look at the following drawing:
http://www.action-electronics.co.uk/pdfs/Speedline%20Severn%20Ver2%20-%20Erik%20Dijkstra.pdf This is a good set up for the Severn.
The following drawing shows a set up for a 1/12 scale version but does not have all the features of the previous:
http://www.action-electronics.co.uk/pdfs/Severn%201~12%20-%20Peter%20Flew.pdf Have look at them both and see which would be more suitable, we can then work from there to adapt it to your model.
This is the reply that I got back; Hi,
All of the ACTion units are designed to be used with Brushed motors. The Speed controllers, mixers and distribution boards would not be able to provide enough current to run the brushless motors. The maximum current any of our Speed controllers could handle would be 30A and this is our High Power ESC.
You would really need to use LiPo batteries with Brushless motors as these are the only type that are really able to keep up with the sudden surges in current that brushless motors demand. Exactly which LiPo depends on the running voltage of your motors and their current drain, and also the amount of space you have available.
The sound system would work but but none of our units will record sound once in the boat. The P100 have .WAV files loaded onto it using the P100 Programming CD and USB Cable. The P100 is not really designed to run 2 speakers so I would stick with one.
