I've read a couple of threads that talk about the engine idling forever as though this is a bad thing? Is this true?
My hyper.21 runs great, not to hot, pulls away good and has a good top speed with smoke trail at WOT. However, it will stay idling for a good few minutes, just enough to stop the clutch engaging, with a nice constant sound. I'm not sure how long it will do this 'cos I just do what I need to do then send it on its way, but it has idled before for a good 5 mins while I've tinkered.
It started to get a little hot then, but only because there was no airflow over the heatsink. Should I be worried?
