So I got off work today ,and I had done some trading and my new 450 heli was sitting on the door So I had to take a look at it and the wife was not feeling good so I thought great we can stay home and watch movies and i can play with my new toy.I was not planning on doing much but I put the skids on and some new blades then I thought as we started watching the movie I would do some simple setup I NEVER mess with them in the living room but hey it's just a quick look at the servos right.... well I turn on the transmitter and plug in the esc put a lipo in and the esc starts beeping ...I thought it was going into setup mode as some do when you power up at full throttle and then thought the throttle must be reversed ... I rev. the throttle plug back in and it beeped then went full throttle straight up into the ceiling and stuck the flybar paddle into the drywall So now the wife is sitting there looking pissed at me the heli is broke and I have a hole in my ceiling brand new blades are trashed ....that's why I don't do this stuff in there ...shortest fly I never had

I would have loved to have been a fly on the wall well on the other side of the room anyway LOL to see the look on your face. Sucks about the Heli but thats a good one...

Almost the exact same thing happened to me about 4 years. I was building the heli on the edge of a bed in a hotel room. I managed to stop the rotor blades with my face. Fortunately, I didn't get hurt.

always unplug the motor from ESC when testing e-helis. If you need to program/check throttle, loosen the motor mount and slide it so pinion disengages from main gear. This way you can make "what almost happened" threads instead of "what did happen" ones

Another method to use while programming is to unplug one of the three wires leading to the motor from the ESC. It won't power up, and you can still hear the tones. Plus, you don't have to reset the gear backlash again.

Drywall is inexpensive to repair comparing to your heli. Look on the bright side, nobody was hurt and that's the main importance.

Damn Dood, that's sounds scary being hit in the face with rotor blades.
Glad to hear you weren't maimed by the rotorblades.

It freaked me out. Happened the same way, too. Flipped the servo reverse switch on the throttle channel. The esc shouldn't have armed, but it did.
The reason I didn't get hurt is because the rotor didn't have a chance to get to full speed.

How I set mine up is I have an old 4 cell nicad pack and plug it in one of the ports allowing me to use all controls no need to plug the main pack in.

I'm a fan of unplugging one of the motor wires too. I like to hear beeps. The only thing to be aware of is if the esc goes into setup mode then when you're playing with the servo travels, you may be messing up the ESC settings. Basically, if the beeping stops in the first 5 seconds you should be ok, if it keeps beeping, then stop.
Once I converted a .46 sized 3D plank to electric from an OS .40SF. As a nitro, I could turn the transmitter off sometimes and nothing would happen after a flight (other than run down my reciever battery). Well I had a cheapo ESC and as I walked into the pits I turned off the transmitter...The 42-60-500kv motor sent the 15X8 prop to 10,000 rpm with me holding the plane in one hand and trying to find the transmitter with the other. Another modeler came over promptly and helped me out and all was well. Scary though

High Voltage just works better

All I can say is I have setup many many heli's and this is the first time anything like this has happened. Also like I said I really was not going to do much just wanted to check out the servos and stuff I should have set the throttle hold but I was just messing around and not thinking ....funny thing is as I was naming the program in the 9z I named it "stunt450" as not to confuses it with the other ....guess it lived up to the name , or maybe it did not want to be the guinea pig heli
