Ok, my Caliber 5 looks like it is a good heli except for one thing...how are you supposed to see into the carb? Theres no way to see into it due to the front of the heli and I am not sure if I need to reverse the throttle switch. I have an OS Hyper 50 in it. Is WOT toward the front of the engine or towards the rear? Any help would be appreciated. Also, How do I do the after run on an engine I cant get to the carb on? Jeff
