This is what a real German Stratus Crash looks like...

[freddyferris]

when you loose Tail control because of a F... lock out....

I'll tell you more as soon as I have more infos about hwat happened exactly... it will hopfully prevent you guys to do the same mistake...

Fred

[Mille aka Fredrik]

What happened?

I crashed mine Sunday :bomb:

This happened while I did some aileron tic-tocs. Somehow the wash-out hub had slipped of the washout pins and were totally locked. Not much I could do. That crash cost about $600 :(
Anyone else who have had this failure? The wash-out hub was the alum one.....

[kthane]

Yikes :arggg: That looks pretty ugly.

[WayneBrown]

I think it broke..
that sucks.

[EricLarson]

Hate to see that Fred. Did you have any control? The 149 is pretty bullet proof but you should get it checked out to see if that was the cause.

Another thing that I see as an issue is the power wire coming unplugged from the receiver. I extend the power wire and make sure there is no way it can come unplugged. I have also been installing Futaba plugs in place of aftermarket ones as I had some "glitching" I traced back to my power plug being loose.

Not saying that was the cause, but it is big possibility as it looks like you had no control to shut off the motor after the crash. If the RX works, it probably lost power somewhere. The tongue still looks attached.

I assume battery and regulator power are checking out ok.

Did you have the canopy on it? That is the 1st time I have seen the top of the frames broken.

Either way that sucks. I have seen and had some bad ones, that one is in the top 10.

[freddyferris]

Isn't my Heli.. thank God!
He flew without canopy..

As the pilot said on our german heli forum, it seemed to by a rx problem.. but doenst realy know for the moment...
As I said, if he finds out what caused the crash i'll writte it here...
This sure is one of the badest crash i've ever seen...

Fred

[EricLarson]

:) well that is good, bad for the other guy...

I saw Matt throw his RX battery out of the heat shrink during a revers pirouetting tail slide. Needless to say it pirouetted in to the ground at max piro speed and terminal velocity :shock: It was something to see...

I would highly suspect loss of power. A crystal or complete loss of RX is a possibility, though like I said the 149 PCM RX is really durable.

[freddyferris]

I'll let you updated...

BTW: Eric: did you get my mail about the event?

Fred

[Dr.Ben]

Out of curiosity, if you had a lock out (vs what Eric hypothesized), why was the engine still at WFO if the fail safe was set to go to idle? Clearly it ran away on impact based on what's left of the poor clutch bell.

Ben Minor

[freddyferris]

He told us he had no controle about throtle and tail..

Cant tellyou much as it wasnt me who did that mess :)

Fred

[WillJames]

OUCH!! Definitely not a pretty site. Sorry for your loss.

[DavidH]

why was the engine still at WFO if the fail safe was set to go to idle?

Ben,
Sadly and scarey there is a lot of pilots using PCM receivers that don't know how or just don't do it. They don't set up the fail safes so if signal is lost or RF interference that the model will not fly away.
When I am helping someone with there PCM radio and setup. I have made it a habit to look at there fail safe settings. Sometimes they will have the throttle set to go to idle on throttle channel. But then they will have a governor and have not addressed turning it off if something happens.
It is pretty scary how some of the fail safe settings are set. Lots of pilots try to set them up to save the model. They do realize that Fail safe is settings so that if there is a problem that the model will stop flying where it is currently located. We have been lucky I guess and a run away model has not hit someone.

David

[Dr.Ben]

Yeah,

You and I both do that. Having FS for throttle and GV-1 set for idle/OFF is a great diagnostic tool, as well, because it'll help tell you whether the crash was a lockout or some other kind of power failure. If throttle is set for hold-last-command, you may never know.

Ben

[Rada70]

how do you set the fail safe on 14mz with the gv1. thanks

[DavidH]

Rada,
I don't have a 14MZ. But you need to set the throttle channel to go to idle position. Then set the channel that controls the On/Off of the GV1 to turn the governor off in failsafe mode.

For throttle channel, pull the stick all the way to the bottom if this is where the engine is idling. Then push SET for failsafe that channel.

To turn the GV1 off, turn the switch on the transmitter that controls the GV1 Off/On to the Off position. Then push set on the fail safe for the channel that the On/Off lead is plugged into.

You can check if this is operating easily.
Turn on the transmitter, then the receiver.
Push the throttle stick wide open, now scroll thru the menu on the GV1 to the SWCD screen. It should say ON if you have the switch on the transmitter in the On position.

Now turn off the transmitter only. The throttle servo should move the throttle barrel to the idle position. The menu screen on the GV1 that is in the SWCD part of the menu should change from ON to Off.

If it does all this after the transmitter is turned off and the receiver is left on. Then everything is golden and the fail safes are set correctly.

"how do you set the fail safe on 14mz with the gv1. thanks"


HEy! My thred is usefull!!! :)

Fred

[Dr.Ben]

David's notes are fine for the 14MZ. There is no MZ special software per se with respect to the use of FS for throttle or GV-1 ON/OFF.

Just make double damn sure you confirm what the GV-1's status is when in FS by checking the SWCd screen on the GV-1 amp.

Ben Minor

[Rada70]

Thanks Dave.

I saw Matt throw his RX battery out of the heat shrink during a revers pirouetting tail slide. Needless to say it pirouetted in to the ground at max piro speed and terminal velocity It was something to see...
---------------

Eric, what do you mean out of the shrink wrap ? did the cells fly out of the shrink ? or did Matt heat shrink the pack to the tray ?

[SteveL]

Why would anybody set the governer up not to shut off at idle?
I know GV1 gives you the ability but that makes no sense. :dontknow

[DavidH]

Steve,
There is a good number of pilots using the GV1 that think all they need to do is set the throttle channel to go to idle only in failsafe. With the GV1 you also have to set the GV1 to failsafe to the Off position using the Aux channel that controls the on/off of it. Just setting the throttle channel to failsafe to idle will not turn off the GV1. Even if stick switch is activated on the GV1.

And if your referring to Eric's post above about Matt's crash. Failsafe's are not going to work when there is no power going to the receiver. <G>

David

[SteveL]

No I have a gv1 on a gasser so I know what you mean. Here is my question? With a GV 1 you still have the option to have the throttle position overide any switch or setting on the gyro. If you set it up like that and set you failsafe to idle the gov will shut off (ask me how I know). I cant believe anyone would set a gov up to where the throttle position was not the master control.

[G MAN]

If you use a CSM governor,it automaticlly goes to idle if you have the FS set for idle in the trans. Dont know about TJ though. IF you loose battery power it cant go into any failsafe position because nothing works anymore. DOUG
