A mate was flying an ex Dave Hollins hughes 500 turbine vario model and he felt something was just not right in the way it was responding to tail commands so he landed and as he landed and reduced the load the tail totally disengaged with something that sounds like yours suffered with.

He thinks its perhaps down to the drive shaft being a tad to short so allowing a fexible joint to move.

Apparently if you assemble it one way eg tailbox first then into model or the otherway around you can detect the movement the other way you can't.

Is you sprog like mine goes and straight to the wife and gives her all the gory details before you have even switched off the car.

After months of work, I finally got my fully-painted and finished NH-90 out for its first flight last weekend.

I was hovering it and about 5 mins in, the tail let go. I was very very lucky. My confidence level hadn't built up yet, so I was only about a foot off the ground when it happened. Just very minor damage to the retracts and a little paint scrape. Another foot or so higher, and being so heavy, it would have been pretty much toast.

I've using the claws at the mech output shaft and tail rotor. I thought one of those let go. Turns out, something I never would have expected, was the ball and screw came off of my tail servo horn. Could have sworn I had that tightened down pretty good....

Seneca, i trully am so sorry to see such a great inability for you to be capable of building anything beyone a century/funkey ARF ... If you come to IRCHA, i will let you take a REALLY close look atthe startup sequence of a turbine, ill give you a really good, close view of the exhaust pipe ...

After a quick glance through Seneca's most recent postings, I concluded it best to place him on my ignore list. My first use of the list!

He's got a link to it right in his sig. Rather curteous of him I'd say...

Damn SENECA did you poop your diapers again because you seem to be in a ****y mood, hay is that the turbine you own or just one that you taxi around. Remember that Wojtek has more money invested in Quote "toys" than you made last year!

And if you like i will also let you have a close look at my exhaust on my Hughes 500 during startup

My 2 cents.

If you take this wrong, sorry, but I'm just saying what I saw.

Sorry for the loss of the nice 230 but if your going to fly it like a pod n boom it's going to happen again. I understand the Turbines are running no where near the power thay have avaliable and I don't think the mechanics avaliable for them can take flying like I saw in the video very long.
Scale like flying might keep the failures down on the heli's as nice as your.

?

Why is it everytime we have someone post some good information on here that people can learn from and possibly SAVE their own machine from a catostrophic failure and crash (whether it has a turbine or how much it costs is besides the point) there is always some jackass that comes along and tries to ruin it by hijacking informitive threads? Seneca why don't you go back to the main forum and stir your usual crap? Woj.. and Alan thanks for your contributions here.. those of us who are interested do learn alot from your mishaps and successes with your models and it does inspire other modelers to pursue neat projects no matter what they cost or are powered with. Looking forward to seeing the NH-90 School Bus finished!

vetrider,

i do not agree with you on this at all .. all a scaler is is a shell of fiberglass and a few extra LBS around a pod/boom setup .. my 230 had a bolted on aluminum boom running all the way through the whole tail. The failure on the tail would have happened if this was a pod/boom or a scaler ... if built right, you can push a scaler any way you want .. in the case of my 230, there is a known problem with the blue couplers that failed on mine (well, not that well know, because it took talking to a few people to find out that these are failure prone, and fyi, one of the failures was on a pod/boom glo powered heli) when i rebuild the 230, i will modify the tail, and otherwise will fly it all the same, and when i feel comfortable, maybe some aerobatics will be in order .....
