But surely if you unplug the battery first without turning off the transmitter, there is still a chance that the transmitter could malfunction or someone could accidently knock one of the controls.

If this was to happen when you were disconnecting the battery on the helicopter, the blades could start rotating before you had a chance to disconnect it.

I totally agree with bod.
Switching off the transmitter before going anywhere near the helicopter must be the sensible way to do it.

Your point number 2 even stated this.

There is far more chance of a radio glitch if the transmitter is still powered on.

And this was also copied from a website so does that mean it's true?

q Always turn the transmitter on first
q Plug the flight battery into the electronic speed control (ESC)
q Allow the ESC and gyro to arm and initialize properly
q Fly the model
q Land the model
q Unplug the flight battery from the ESC
q Always turn the transmitter off last.
every single set of manufacturers instructions say the above,this was pasted from a blade 400 3d.hope this helps.

If it was'nt true then why would they post it or have it in instruction manuals.

Well while it's true that it does state that they need to remove battery first (i just googled some other manuals), they all state something like this:

This aircraft is radio controlled, and as such is subject to possible radio interference
which may cause complete loss of control and subsequent uncontrolled crash.

Just to clear up a few matters.RC HELICOPTERS ARE NOT A TOY like anything if used incorrectly they will cause problems and sometimes injuries.
Before i got my 1st heli i went to a club to see other experienced people fly them and listened to their advice,when i had gained enough knowledge i bought my own and got the club to set it up for me and make sure it was safe.
It took me 5 weeks to learn how to hover it about 1" above the floor
and then i progressed an inch at a time with training gear attached and got to the stage where i could hover it stably about 5 ft in the air.
Even when i used 1/8 scale nitro trucks the golden rule was the same always turn transmitter on 1st then start engine and vice versa.
A lot of the replies on this forum have been helpful and appreciated but some have been just rude and what you expect to hear in a playground.

Thinking about it a bit more, it might be the case that when the transmitter is turned on and all of the controls are in the neutral position, a signal is still being sent to the receiver.
This signal could be there to ensure that the helicopter servos are kept in the null position and also so that the motor controller gets a strong "off/do not run" signal.

This would make sense as the transmitter signal which is telling the motor not to run would be far stronger than any possible interference sent by mobile phones, radios or other electrical items, so that they shouldn't have any ill effect.

In effect, turning the transmitter off before going near the powered helicopter may well make interference operation more likely.

If this is indeed the case, I stand corrected on my earlier post.

It took me 5 weeks to learn how to hover it about 1" above the floor and then i progressed an inch at a time with training gear attached and got to the stage where i could hover it stably about 5 ft in the air.

I'm a helicopter engineer, and as most of the places that I work are in remote locations, it's not unusual for engineers to sit in the front of the helis when there are test flights or radio checks required, and we often get to take control. (never allowed to take off or land though).

If RC helicopters are as twitchy as the real thing, I agree that learning to hover must be extremely difficult.

I think they are glorified toys. I have one, and I am aware there can be issues with others using the same RC frequency. OP did you know that? I'd be surprised if any 'club' you involved yourself with didn't explain this.

When i first went to the club someone had a transmitter with a telescopic aerial and they used a frequency checker and put a flag on the aerial so everyone knew his frequency.
All the other transmitters used 2.4ghz and were binded to there own helis,on my old 10 channel transmitter i had about 10 planes and 6 helicopters in the menu and these were all configured to it.

2.4ghz is the frequency of my O2 broadband router. Interference is possible perhaps?

At the heli club they all seem to have had smartphones and no mention was made to turn these off?i would expect that you could get a minor glitch on a servo from interference but the ESC (electronic speed controller)which controls the motor speed should be unaffected as they have inbuilt safety factors such as soft start etc.
