Not having benefit of a local club and lake, my refurbishment of the Sea Queen was based on the many useful articles on the MBM forum. So the electrics, as installed in my other thread, are still very much experimental. I have access to a natural lake which is largely surrounded by reeds and trees. So, unless my wife is doing her wild swimming, retrieval of a dead boat is complicated and I live in fear of a tripped fuse.
It occurred to me that a power back-up, by way of a fused bypass of the main 60amp fuse, would provide at least the possibility of getting the boat back on a reduced throttle. My radio box still had the throttle servo from I/C days and the Futaba T6L radio had spare channels; one of which was just a flick switch. For this idea to work the Rx has to have a BEC supply independent of the motor ESC (and before the fuse) or be battery powered. The existing BEC from the ESC has been interrupted by a short extension lead which has had the red wire disconnected. This allows the original system to be reinstated pondside if required, by just removing this lead.
A 30amp fused loop was introduced to bypass the main fuse and is operated via a micro-switch activated by the old servo. Just remains to be field (pond) tested.
My only concern with the new Futaba 2.4GHz system is the very short aerial. I have a hole in the cabin window to poke about 60mm out for reception but wondered how fussy these aerials are. Would it work inside the cabin? Any advice gratefully received.
