Twister Storm 3D - Starts by itself!!

[DapperDan59]

Hi everyone, first post here... I had an incident that was pretty scary to say the least.
I have just bought the Twister Storm 3D, and was overlooking the control of the tail servo the other night in the lounge room of my house. I throtled up a little and down and then up and down checking the operation of the tail, then was ready to pack everyting away after I was looking at the tail servo not centering. (Another problem, or could be normal)

Anyway. the throtle was fullly off, and as I was about to disconnect the battery, then out of nowhere, the heli started to throttle up by itself... and I mean FULL to the board revs... well I had no control what so ever, I had to wait and almost clsoe my eyes waiting for the masive crash as it did, end up having 3 x 1/2" gouges into the wall from the carbon fiber blades, and a few things broken on the heli. Well I'm not happy about that as you can imagine.

I found out the next day after inspection of the TX and the heli, that the TX has a faulty ON switch.... so when the TX is off, the heli starts up FULL THROTLE..

My question here is, is there ANY way I can program the ESC to shut down when it looses signal from the TX. I find this set up most dangerous.


Thanks.

Hi and first welcome , but beware it's a little mad here so hopefully you come ready equiped with a sense of humor

Anyway I am sorry I don't have enough knowledge to help much with your problem but is it possible the throttle channel is reversed ?!

Here is a golder rule for electric flight :
Either
Remove or unmesh the motor pinion or

Remove the main blades !!!!

some may say unplug a wire to the motor from the esc (speed controller)

Use caution you must !, if that approach you use !!! controller damage you may !

Se told you it's nuts here ;-)

Whilst not familiar with your particular setup, it should be possible to setup a "failsafe" mode, so that in the event of lost signal, it does a certain action.

It might be that yours is set up to add throttle in case of a "brown-out" meaning that assuming it was flying, your heli would try to keep itself aloft as opposed to slamming into the ground. Either way, at least you now know what caused it (ie faulty power switch on Tx) and I'm sure that's now resolved.

Glad it wasn't any worse than a bit of household damage...doesn't bear thinking about if you had kids/family in the room.

3d storms have no on-off switch ! as std ! i know i have one
so with any electric heli safty the order of starting and finishing flight is and has always been radio on heli on - to power down heli off (unplug) radio off if this was not followed then its not a wonder you had an accident
a heavy learning curve but one im sure you wont do again

oh and welcom to the forum

Thanks for the welcome.... and yes it was done properly with the tx on and THEN heli on... this is not my first heli, so I klnow I had that right.

Definately the switch problem, which is now fixed, but I think it is still a worry that even when your carrying the heli to the place you want to fly from can start without warning, which it actually did the first time I powered it up after buying it.... I thought I might have bumped the stick, but I know now it was not the case.

That would be good if I could somehow find out how to set that up... I would rather the later than it starting by itself out of control in the wrong location... and I was luck know one else was in the room...

Ha, funny Rachel, thank you... but no I had the throttle working correctly, I have already had it flying with no problems, except for the pilot :0)

So I think it is something to do with the ESC maybe, I need to somehow program a failsafe mode into the whole mix. Any ideas?

Don't blame the Storm

It's not a Twister Storm Issue. I have one. You need to find out if it's the Tx, Rx or the Speed Controller. I know the advice is Tx on first and off last but this dates back to before fail safes and your radio should be programmed for loss of signal as this can happen and should result in zero throttle.
There was a problem with the DX6i a few years ago when it gave throttle output when the throttle was at zero. They were recalled and no problems since. Helis are dangerous and you need to assume that it can do anything anytime a battery is connected. But that's what makes it fun.

Well not blaming the heli is ok, but the problem was DEFINATELY the TX... I just need to know now how to program the TX or the ESC to pull throtle if loss of signal. I have fixed the TX now and the switch is good.

[trident3]

It's not the TX you program for failsafe, it's the receiver. No point in programming the TX because if it's failed, it's not sending a signal!

The receivers I use all have their failsafe programmed during binding. After initially setting up the hei (motor unplugged!), I re-bind with the blades at about -1 degree pitch and the throttle to zero. So if my transmitter fails, that's what the receiver will tell the blades and motor to do.

Does your ESC have soft-start? If so then make sure it's enabled, then if for some reason it does go to full power unexpectedly, you'll have a few seconds to get out of the way.

Fail Safe

Which TX/RX have you got? By the way you can blame the Twister Storm for most everything else. Servos, Gyro, Battery, Motor for instance. The Main blades are good though. The esc does have slow start which is disabled after about 10 seconds running as is standard.

I have the standard TX that come with the Twister... I also have the DX6i.

Thank you heaps Trident...... that makes a lot more sense of course... so how do I program the receiver do set it up that way?

Twister 3d is not a bad heli just needs some upgrades like hitec 65mg's 420 tail and all the alloy parts and it a good little flyer ;0)

I think the mgs are a bit over the top, I find the hbs survive well. I've got a gy420 as well and a ds520 on the tail although not sure that was necessary but it came with a gyro. The motor is ok once you figure out how to change the bearings and 5C charge Tipples are quite good. The canopy looks good, shame the instructions are wrong. Can't even mount the esc the right way round or connect it to the correct colour wires. Calling the gyro competition class sums it all up really.
