I have many OMG I am a dumbazz moments , here is one:

Just finished building a trex450 and thought it would be a good idea to spool it up and do a test hover in my build room.....


The room is 14' square with stuff around 3 sides. So really only the door way and the middle of the room is the only open space.

As I start to spool up everything is looking good. At half throttle I give tail commands and make sure the tail is working right, so far so good. 3/4 throttle no hover Creep up to full throttle still not even light on the skids Its late and I have been up half the night finishing this bird, I slam the collective back down in frustration. The Rex jumps to life and heads straight up screaming to the ceiling Here's where I really get a Darwin award. I step forward and reach up to grab the heli by the skids. I miss it on the way up, although it has slowed considerably. Just before it hits the ceiling it comes back down and I grab it then. It all happened so fast I didn't even think about how it could have come out badly till after the fact. Thankfully no damage to the heli, house, or me!

simple error, pitch was reversed
Lesson learned: no more test flights in the house

I put the fun in dysFUNctional :)

My dumb arse moment could have been really bad but I got lucky.

I had just finished my first night shift for the week, took out my Logo 600 for a fly. The previous afternoon I had put the tail boom back on and in my rush to get to work I didn't check the direction the tail was spinning.

So on spool up the 600 starts piroing anti clockwise, bloody tail rotation was reversed. No problems there, hit throttle hold, put the heli on the bench and start to go about fixing it. Now this is where sh!t goes bad.

Firstly I put the TX down next to the tail, something I never do. Next I get my tools out of my bag and place them on the bench. Then all of a sudden teh heli starts spooling up. I start flicking switches on the TX hoping to stop the spool up, no good came of this.
So I get below the disc, grab the frame and hold the heli to the bench and pull the battery lead which I should have done as soon as the heli was put on the bench. I waited under the heli until the disc had stopped rotating and stood back in complete confusion as to why it spooled up. That is when I felt the sticky stuff running down my hand. Blood and sh!t loads of it were pouring out of my left thumb. As I was busy flicking switchs on the TX the tail blades were slicing and dicing my thumb. In the heat of the moment I didn't feel a thing. Five cuts later, two were to the bone and the tip of my thumb was only hanging on by a thread of skin. Both Radix 105 tail blades were destroyed as well.

It turns out in my post night shift delerium, I had turned the TX off without even realising I it. The other issue was that I had just recently put a new RX on the Logo but had forgotten to bind the fail safe to zero throttle. I had bound it at mid stick.

Luckily things turned out okay for this could have really f#@ked me up. Also if the heli had been on the ground it would have beat itself to death as I would not have been able to get near the battery connection to pull the plug.

Live and learn.

Man that sucks! I think I would have rathered the heli beat itself to death rather than filet my thumb.

even not doing anything would have been better than nothing...

It was the first time I've had a close call with my heli's in over 1600 flights. What dissapoints me the most is I work in the mining industry and saftey has been indoctrinated into me over the last 15 years. Part of my job is developing Safe Work Procedures and Job Saftey and Environmental Analysis. I can't go through life weather at work or home without seeing the dangers in everything we do.

This time I blew it big time and I must say it even one month later I still get the chills just thinking about the potential for serious injury.

And I broke the one rule I have always run with when I'm doing night shift, never fly the morning after my first shift of the week. Never again.

I went to run in my new Hyper 50. Went to the field, fired up the 600, all good, give it throttle, hmm it's shaking. Probably too rich or something. Continuing to give it throttle, more shaking.
More throttle, shaking disappears, but the head RPM doesn't rise and the rex just barely lifts. WTF did I do?

Well, that what happens when you have one main blade reversed!

Another time I autoed a bit far away. The field was uneven, and I tipped over after landing, at quite a low head speed. Engine seemed to cut off. No biggie, I'll just go there and straighten it up. So I, for some reason, switched off the t.hold. Two things became apparent at this point:

1. The engine was still running;
2. The TX was in IDLE 2

Destroyed the front gears of the torque tube. Lesson learned: After touching down and proceeding to do anything at all with the model, brush the TX to make sure it's in Normal and throttle is all the way down.

You live and learn.
