I'll chime in since I'm an electric guy who runs at my local track with the nitro guys. I'll admit it makes it much tougher when the electrics and nitros are running together. You really need to have your wits about you and keep your eyes open. What makes it tricky is that you don't hear them coming. But if you are doing your job as a marshal you should have a pretty good idea of where the cars are in relation to your area and which drivers are likely to stray off course. With that said I would rather marshal the e-cars than off road 1/5 scale - I have had the unpleasant experience of getting popped in the leg while marshaling a Baja 5b qualifier.
