Ok, maybe i am too frustrated and just need to blow it off, maybe i got a lemon, who know? But i've tuned YS and.Webra engine on heli before. if you know webra, its one of the infamousliy hard to tune engine on heli. however, if you look closely on my post, i wasnt complaining about tune, i am not up that stage yet. I was merely trying to get the engine to idle without plug heater attached. i wasn't able to do just that before i did my WOT attempt. It did not response to tweaks. Dont you think something is wrong on my engine?
