View Full Version : Idle up=Crash
Been flying about once a week for a month or 2 inside my garage (Esky CP2) and had such a nice day with mild breeze so flew outside. Was great hovering 5-10 feet up, no tricks or anything, had just taken my BCX inside as there was about 1 knot breeze, so I decide what the heck I will try the idle up switch! Mistake #1, bird does piros, and lost orientation. Mistake #2 dumb thumb down collective (Thought switched idle OFF), Mistake #3---thought idle off, bird doing crazy chicken and throttle off, motor (3rd main) starts to smoke, I look at radio (OEM Esky) and IDLE UP STILL ON!!! Switched it off and chicken dance ended. Hope I did not smoke the 4:1(2nd one). No more idle up for awhile! :arggg:

The stock radio is to blame, it is very limited and sends the ESC into full throttle so quickly that the tail cannot catch up, hence unintended Piro. About the only time your going to turn the idle up on is when you have landed and can get the rotor to speed without the tail moving, or when you have the correct rotor speed and pitch as the idle up setting. With a good Transmitter you can adjust all of this to make idle-up a seamless transition. More importantly you can assign a switch on a good transmitter for throttle hold and shut the motor off in any mode with a simple flick. The motor probably smoked due to the extra strain of beating the rotors into the ground for a while, consider yourself lucky if nothing else puffed.
It has happened to me also, so don't feel bad.
Thanks for reply, that was exactly what happened. I will buy another $8 370 motor this weekend and if the 4 in 1 is still ok (my 2nd one) I will give the heli another life, if not will just wait for the 450 V2 that is delayed in customs. I cant wait for the 450 but I still like the honeybee as it is quite a challenge and it feels great to trim it out so it hovers by itself (nanoseconds)! Also thinking about the fact that a crash in the honeybee is a few $ and no idea about the trex $$$$. Just hope I dare to fly it after all the setup, DX7 etc.

Most people says its cheaper to crash a trex. I dont know but thats what they say.

In my experience the trex costs more time to repair than the cp, costs are very similar in parts. The T-Rex will be a big step up in performance.
