Hi John,

It is a good engine. There were no switches involved since the ECU needs a signal from the RX in order to turn on and as long as the RX is off, so is the ECU. However, it is a good idea to unplug the battery for storage and charging etc.

I guess you don't have to use the start box but why won't you? You would still need the propane and air supply so you might just hook those up to your start box and not have to worry about lighting the glow plug manually etc. Also, the start box will tell the different stages the engine is on not to mention the fact that you need the start box to set the idle of the engine - I remember you needing to push the ignition button momentarily if the idle was above a set pressure.

Hope this helps.

Adil
