POST FLIGHT AUTOPSY.

For those who like post crash amusement - read on.

I had (note past tense) a smoking hot goblin. Kosmic 200, futaba servos and cgy750 gyro - xnova 4530 motor... It kicked ass and I was really starting to like it...

Upon doing some moderate to sometimes hard3d, i decided it was time to do a psycho - a high energy maneuver that does impress but man it puts a lot of stress on a heli.

I did not really go that fast into the maneuver flying from right of field to left. I pulled into a 3/4 piro while traveling at a moderate speed, then aggressively pushed out while continuing the piro.

It appears that the main blade broke and folded into the boom chopping it clean in half about 15 cm back from the tail box


Now here is where its gets a bit funny. The head of the helicopter was still flying and piroetting madly towards me and the spectators. I still had control and managed to auto the spinning head into the ground rather softly. All electronics survived thank heligods....

The end... BTW thanks Crash... and yes @simon I gotta come up and visit for sure.... what a day... Will keep you informed on the rebuild....

 

Damn.. @smakmeharder

So you need a new kit?

 

Luckily i have 2 new frames on hand, the head and tail appear to be fine and the gears are still intact. All servos are fine and the motor spools no problem. It looks as if I will need to change the 2 side frames, the boom and maybe a couple of unseen damaged parts here and there. Pity about the main blades however.... ...I think it will cost me around 300 ish seeing i have the frames.. Such is life @iggy!

 

what...... crash crashed

 

crash exploded....

 

My rule-of-thumb is that if you have broken your frames and boom, it's a re-kit. Harvest your electronics and any bits that are OK as spares, and get a new kit...you'll enjoy it more than putting 'humpty together again'

dam went home to early. what a sight that must of been, half a heli auto, something you dont wanna practice

 

It's was an epic explosion.. the worst part is the canopy...

 

Yep your right @Manyc... the canopy... :-( sigh... Oh well what can be done about that? Lucky i have a spare but unlucky I broke my angrybirds.... Jason wanted that canopy.... Looks like he has it now...

 

And he will be wearing it as a hat knowing him...

 

I must say that the explosion of the tail was impressive but the graceful semi controlled auto of the body was truly spectacular!

 

It was almost like watching a snowflake fall to the ground - like nothing else i have seen todate. Sigh.. thats helis for you! I had to laugh at @3dmicks comment - "that looked like my heli last week!" and it did....

 

It seems rather unlikely. At least exceptionally unusual.

I blame nylon bolts fixing boom, they are guilty. It is quite easy to overtighten them. This way they loose strenght and break. Did you have nylon bolts?

Actually I think Bert explanation that head has to be tight is wrong.

Almost all Goblin boomstrikes are related to boom moving upwards in flight or less often to broken ball links.

I can be wrong. False statements on forums are plentiful. Just another point of view.

 

Actually using servos after crash can cause more problems than using unbroken airframe parts, head or swash. Servo can work fine without load but go crazy under heavy load in flight. Been there done that.

On the other hand you are right. I totalled my Gaui X5 because aluminium servo mount broke in flight. Previous owner was crashing it a lot. Some alu parts can break occasionally if we crash often.

 

It Could be, cant @utrinque I cant rule anything out. I know this much, I believe any helicopter above 500 size can be broken if you fly it hard enough... you just have to learn the right tricks that break them.. I am getting there! lol...
