I bought the engine ready built bit looking pretty wrong and with basic moulding .http://www.flickr.co...0ck/7166175657/
But I always had the intention of stripping it and repainting / super-detailing etc so I wasn't worried
Good thing with it being a Jeavons model is you can do a lot of cutting / routing out without causing any loss in strength
Re- the lights,
I have red "marker" and white "headcode" lights in both ends (effectively 2 sets, wired 2 white to 2 red) so what the extra relay does is to sit connected to the reverse wire point (black wire) on the VTX main board, so when you select reverse from the hand controller, the black wire changes from 0v to 12v - this changes the relays on the VTX board to reverse the motors, but with the extra wire fed off it also activates that relay which alternates between the 2 sets of lights... if that makes sense ?
now with the DMR in the mix it is obviously more 'sensitive' than the manual switch and thus the 12v were all going to the relay which was in effect competing with it -- so it wasn't sending power to the VTX relays to change direction
It wasn't helped by the fact that the actual way the DMR was working (high and low volts on black wire) was opposite to how the guide said it did. plus the fact the chap from 4QD is, dare I say, "less than customer friendly" and not very helpful other than to assume I had wired it up wrong and blown it
all sorted now, i just need to introduce another transistor to interact with that relay to switch it without upsetting the DMR !!
The it will be on with fitting the smoke unit !
A vapouriser type which uses tap water and no heat at all - works amazingly well
Look up Foggy units from http://marksmodelbits.com/
Tell him Mike sent you.... :-)
I'm the first guy who's bought one of his units for model rail use.. but I suspect will not be the last once people see it in action
