Just like the pics in heliaddicts post https://rc.runryder.com/rr/rrpw.htm?p=5660183&i=1

a local guy at my field managaged to boom strike in vegas this sat at the FF.

he was putting on a good show and was down low doing a pushout when BANG
he put a hole in the fuse and broke the belt or pulley , of course it started piroing but he`s good enough he got it down in one piece.

he took it over to show Burt K. and the distributors (i assume)

they had him put it undercover so one one could see it to be dealt with later.

needless to say when it came to big picture time this little goblin was not allowed in the photoshoot with the other 12 or 12 goblins on
display.

Now, go enjoy flying your goblin if you have one.

believe it or not, this is what any company or group would normally do. it is done to avoid speculation. they have to look at it closely and figure out pilot error, build error or manufactured flaw

The Goblin that experienced the boom stike in question, was mine. The only reason I put it away was because I took parts off of it to loan to another pilot. It would have looked really sad to see it out there with missing parts. The damage was very minimal and the main blades were still intact. Still love the heli ! It's back together and flying.

What, you guys don't trust Pro pilots and Heli manufacturers for showing and pushing their products?


Did Bert throw out those Voltz lipos when he was done flying too?

The issue on mine was with the (Goblin Manual Page 39) Part H0037-01 Boom interface. This metal bracket is riveted to the boom. The plate was not perfectly flat and level which once installed caused the boom to raise up near the tail shortening the distance between the blades and boom. A simple shim would have corrected the problem. All 12+ Goblins were checked at the show for the same issue. No other ones were found. The damage was very minimal . Small hole in the boom. Main blades were still intact. She's back together and flying.

Can any Goblin owners give what the distance from blade tip to the top of the boom is. I measured my buds kit at 160mm and it looks like a good distance. Thanks.

I was wrestling with this in the weekend. My mates goblin and mine side by side it looked like my tail boom had been on viagra, with a noticeable upwards pointing.

The clearance from boom to main blades was 110mm.

I too thought the mounting plate had been assembled poorly. Given it is a metal v shaped slot that slides into a mating shape, be hard to get it assembled wrong, right ? Well I took it apart and reassembled..... now I have 140mm for clearance. May have had the plastic bolt head caught somehow.

Yes.... 145mm is plenty of clearance. Anything below will need to be shimmed. When I had my boom strike it was measured at 120mm. I had flown it approx. 10 times prior (mellow break in period saving it for Las Vegas Show). At the show I had my friend(hard 3D pilot) pound the Goblin which caused the boom strike. He pushed it real hard (at my direction).

145mm clearance is what Bert was checking for on all the Goblins at the Las Vegas Show after my boom strike. (Wanted to say thanks to Bert for taking one of his booms off of his Goblin and giving it to me for replacement).

Question how can people get so many different measurements of distance. It should be bolt it to these holes and you are good to go, there should be NO questions as to the boom and where that end height lays, hopefully something they would revise as obviously some new to hobby simply are not going to do that and check period..

Its all in the mounting of the boom OICU. There is two plastic nuts that slide into this metal bracket fixed on the top of the boom and then there are two bolts on the side that go into channels in the frame, they probably should just go into holes technically. But I'm thinking that there are small variations in the hand made process of the tail booms and they are giving some 'wiggle room'. Basically you back the plastic nuts all the way out, put the boom in and then adjust its horizontal position using the setscrew/nut in the channel, then tighten down the plastic nuts. On this kit though, we didn't have to really do anything except slide it in and it was about 160mm right there.

Understood. It makes sense but they should have it as you say just line up from get go ensuring you can't have it wrong at any point. Oh well I'm sure given info they'll address it.
