Well my mad plan got rolling yesterday, fitting an ESU loksound micro in a Hornby Austerity.
I did a stall test on the loco a while back and it drew 0.43 amps when stalled so this is within the 0.5 max rating of the micro decoder.
I had the dimensions off the ESU website and found that by cutting away part of the balance weight the decoder will fit and still have a healthy amount of air around it to aid cooling. I decided to sacrifice a bit of weight as they are capable of pulling 20 odd wagons and I'm looking at no more than 10 on my layout, I'll do a comparison of a standard and my modified loco's drawbar pull when I finish the project.
I dismantled the loco yesterday and the decoder will be going in the front of the boiler while the speaker will be in the rear of the cab with the bunker as it's sealed sound box.
I'll take some pictures of it but the light in the workroom failed and I didn't have a spare tube.
Fingers crossed!
