Friday, I busted my Raptor 50 up by going inverted 15' off the deck without engaging my idle-up... Couldn't recover in time, and didn't think to engage the switch while there was still time... Not too bad, damage-wise, TT carbons, spindle, skids. Amazingly, the main shaft and the boom survived... 'Fixed it this morning, and went to dial it in this after-noon. It was flying beautifully, so I went inverted for a while...

Well, roughly enough time later to suck the header tank dry, while doing a circuit, still inverted, the engine accelerates briefly, and dies! CRAP! Did I mention I had just changed the tubing inside my tanks? Evidently, it was just a HAIR too long in the main tank, and got stuck on the rear wall. I guess my heli WAS pretty vibration-free, that's like the only positive to this story. So I flipped it upright, botched up the auto because I went to full negative pitch, thinking I'm in normal mode (-3 degrees), but I was in idle-up, of course, (-10 degrees!) and used up a bunch of rpm and even more altitude figuring out what was going on. All the positive pitch in the world wasn't enough to prevent balling it up for the second time in as many days...

And I was doing so well not crashing it lately... There goes my streak. Dargon it!

I'm afraid I'm good in controlled practice, but when it's time to react NOW to an emergency, it shows I don't have a year in yet...

So, I've decided to ground the other two helis tomorrow, at least.

My heli spending has gone way down since I got a Honda 919 :-)

they rarely last forever
sorry to hear about your crash
looks like you were doing great
On your fuel pick up tube length keep them a little shorter
than you think in a high G maneuver they can stretch enough
to hang up

Doesn't your clunk have a feed-through slot? Most of the clunks that I have seen have at least one slot cut in the tip to prevent this kind of situation.

On my models, I always add a second slot. Makes an X shaped cut in the end of the clunk to prevent any possibility of the clunk getting blocked against a wall.

Sorry for your bad luck streak. All part of the game.

Quick comment and new acronym
Guys,

first off, thanks for the kind words. The clunk does have the slot, that wasn't the problem at all. The tubing inside the tank was slightly too long, and the clunk ended up getting STUCK at the half-way mark when inverted. Fuel went through it perfectly well, until the level came down to the point where AIR went though it perfectly well

This became painfully apparent when the post-crash examination showed the empty header tank, and removing the main tank from the frame and putting it upside-down got the clunk stuck again. It didn't do it every single time, but once in the air was enough.

Now if I stayed inverted for 15 seconds at a time only, I wouldn't have had a problem. Haha.

It's amazing how little it takes to bring down an otherwise perfectly flying heli, isn't it? In this case, an extra 1/8 inch of clunk tubing.

I've invented a new acronym after having 2 crashes in 24 hours:

Improper Management of Flight Under Complicated Kinematics or Equipment Distress (IMF_CKED)
