HelicopterHIROBOOther › Jeff G. - I had a boom strike!

rdalcantorrKey Veteran - Salt Lake City, UT - My Posts: All  Forum  Topic


After a year or more of great flights with my Sceadu 50, she finally let me down. The first flight today was great, with moments like this, captured by my brother:

The second flight started with a flip takeoff to inverted flight, downwind inverted turn, into an outside loop. At the bottom of the loop, heli inverted, the blades must have gone out of track because they suddenly slowed down BIG TIME and the blades hit the boom. The boom folded, heli turned to knife edge, and fell 20 feet like a brick. The engine kept running so by the time I got over there, the clutch was smoking BIG TIME. Cut the fuel and stopped the engine.

At first the damage didn't look bad - just a crash kit I thought and a clutch.

But then I noticed one of the balls on the swash plate broke off -

The main gear was ruined

The pitch slider is broken

the blade grips for the tail blades are broken
the belt is toast

and the verticle carbon fin is gone

The main blades were on tight, and everything was tight in the head. I have digital servos everywhere for better flying and to reduce the chance of problems like this.

I have been a HUGE Sceadu advocate on runryder and at the field. I think it is a great heli. But this strike was not my fault and is going to cost a lot.

Can you help me out a little Jeff?

Thanks,
Rick

Sorry to hear about your incident.

Are you sure the broken swashplate was an effect of the blades going out of track, or could it have been the cause?

I don't think there is any way the plastic would have failed from flight loads. That had to have been from the main blade grip getting jerked hard at impact....

I think you should have sent Jeff a personal e-mail with your appeal versus putting it in a public forum. Jeff is a standout guy and I think you have put him in an awkward situation to ask him for some help due to a tail boom strike.

I have a Raptor 50 and have had many tail boom strikes but I have never posted a message in public to Thunder Tiger asking for help in replacing parts. I am not even sure if Thunder Tiger would even respond but we all know Jeff would.

I don't think there is any "warranty" for tail boom strikes -- we all have gotten them...

Other than that, sorry for your loss and the Evo is a great machine.

Is it a EVO or regular Sceadu?

You are very..., eerrrr... wise WiseBob. I probably should not have posted this. But, I am not after a free kit or all the parts free. I just don't think Hirobo should make a profit off of this one (or Heliproz for that matter). If Jeff could supply the parts at cost Hirobo not only looses nothing, but comes out ahead by proving on a huge public forum how well it stands behind its product.

It may have been two years ago now (hard to keep track of time), but when my Fury crashed from a bad glitch because of the clutch bearing problem they were having, they not only fixed the entire clutch assembly, but they replaced about $100 of broken parts that resulted from that crash for free. So not only do they have a GREAT flying 90 size heli, but they have outstanding customer support. As a result, I will continue to buy their products and promote them.

Don't think Hirobo/Heliproz should make a profit on this one? How do you assume or come to the conclusion what and who is to blame? Very poor taste to post what you have in a public forum in my opinion. I have had boom strikes on different helis and in all cases the damage was such it was hard to determine the cause. How have you determined the cause? After a year of flight what maintenance have you done on the heli? How often have you changed head dampners,bearings,etc...

John,
We are sharing some information here and by my opinion there is nothing bad in posts like that that, many people teach themselves on the mistakes of other guys. So the posts like that are very useful, they are an experience for anyone of us!

Sceadu. Maintanance done about two weeks ago actually. Regreased the thrust bearings, changed the dampers, etc. It is one thing to have a boom strike because you landed while pulling back on the cyclic and drove the blades into your own boom. I do expect a heli advertised for 3D to be able to do an outside loop.
Oh yes, and I use a GV-1. I believe it is set for around 1900, but I can try to be more exact if necessary.

Sorry to hear about your crash.

Just out of curiosity, what do you believe caused the boom strike?

Did the blades go out of track or just slow down? You weren't very clear in your post?

Maybe you had a swashplate ball let loose during the flight? There have been numerous post about swashplates splitting while putting in the metal balls. It doesn't seem likely that it broke on impact and the ball link stayed attached to the inner ring of the swashplate. The link would have gone way before the swashplate.

You should be able to still use the swashplate. Just use the unused hole.

From what you have posted, its not a clear cut case of product failure. I believe you should have contacted Jeff G off line. Its putting him on the spot when you don't even know what happened.

Sharing information is great and yes can be very helpful but to put someone on the spot is not. I would still like to know how he came about the conclusion that he shouldnt have to pay retail to rebuild his heli and that Hirobo should share the responsibility. If his reasoning is sound and logical and he has proof of defect than great. If his skills of investigation are that great I might hire him for my next post crash inspection and maybe save me some money too !!! I'm sure all of us could use his services at proving defective components caused a crash. If there is no definitive proof or history of defect to follow his claim than all I am reading is a pilot pissing and moaning about the cost to repair his ship! I agree with wisebob in that he should have contacted jeff privately and discussed a possible solution. Since the ship was maintained just 2 weeks ago isnt it possible that something was left loose or otherwise irregular? A bolt backed out? Bearing failed/worn out? Yes these are all possible and without proof of a defect than the responsibility is with the pilot.

cheers

Ditto.....

I see nothing there that would send me to Jeff Green with a Product warning.
IMO that is the only time you should be taking a crash to the manufacturer.
I had a questionable blade grip about a year ago. I sent Jeff a picture and my concerns. We talked and agreed it was ok to fly, but keep my eye on it.
Well many flights later it MIGHT have failed.
I talked to Jeff about it again out of CONCERN that a particular part had the potential of failing and for him to keep his eyes out for more of them.
He was KIND enough to send me some crash parts, but I didn't ask for them.

This post smacks of plain rudeness to me.

Pin down a cause THEN talk to Jeff in private about it. Post the results if the two of you come to the conclusion it was a weak or defective part.

My Sceadu has had the blades loose energy on me for VARIOUS reasons. NONE of which were the products fault usually they were engine tuning.
From what you describe to me it sounds like a failed Governer and no good backup curves, but that is just speculation based on your description.
Is the magnet still in the fan?

Rick,
if you cant afford to crash then dont fly!

Dont expect Hirobo to pick up the tab for something that isnt a Manufaturers defect....there's a ton of possibilities as to what could have happened. Poor maintiance, a bad head linkage that poped off causing the boom strike, Pilot error...ie poor collective management...etc......


Just cause the Heli states it will do 3d doesnt mean it wont boom strike...Heck anyone can boom strike any heli with poor collective magement. And just because you "Maintanance" the heli two weeks ago doesnt mean that in that time u havent ruined the dampners. I ruined a set of dampners on a raptor 2 flights after putting them in pulling a hard flip after my tail blew out doing backwards inverted.
my Fury crashed from a bad glitch because of the clutch bearing problem they were having, they not only fixed the entire clutch assembly, but they replaced about $100 of broken parts that resulted from that crash for free. So not only do they have a GREAT flying 90 size heli, but they have outstanding customer support. As a result, I will continue to buy their products and promote them.
I seriously find this hard to believe...How many MA pilots out there have had tail gear failures and reported them to MA...KNow what MA's response is...."tuff SH*@ u put it together wrong!" THats not customer service!!!! And to even compare the level of service that Jeff G and Hirobo provide to their customers and MA customer service is out of line! MA certianly didnt pick up the $400 tab after I put my Expert in due to a tail rotor hub failure...and thats a KNOWN manufaturer's defect!!
If Jeff could supply the parts at cost Hirobo not only looses nothing, but comes out ahead by proving on a huge public forum how well it stands behind its product.
Jeff or Hirobo have nothing to prove to the public....Everyone knows that they stand behind their product if anything they go WAY, WAY, above and beyond for every one of their customers. But to demand a discount from them is out of line and taking advantage of their generosity.

Do what the rest of us do...open your wallet and break out the Visa.
