Serial crashing and personal responsibility
Disclaimer: Been flying since 07, built a few helicopters and am basically proficient in helicopter setup and flying. I rarely crash anymore.

So last month I bought a Trex 500 esp from a local swap meet for $250. Looked barely used, seemed like a good deal. Got it home, sorted some iffy stuff out on it, checked it out and ordered a couple of batteries.

Incident 1: Maiden flight the tail is acting violent on the ground. The right answer would have been to cease activities and troubleshoot the obvious tail issue. Instead I dropped gain and attempted liftoff. It got to about eye level, tail started twitching back and forth violently and then went into a piro. Hit throttle hold, landed, a servo stripped and the tailshaft got bent. Repaired, troubleshot until I found the Align 780 gyro was super sensitive to any vibes. Weeded out vibes to no avail so I put a 401 on and that solved it. Test hover in side yard, all is well.

Incident 2: Go back out to field the following weekend. Take off, it is flying well. A sound starts to eminate from the heli so I bring it in to land. The canopy suddenly gets spit off of the helicopter but I continue to come in to land. At this point it is about 20ish feet and I lose all cyclic and collective control. Hit throttle hold and watch it plop on the ground. Look the wreck over and the bolts that hold the washout arms on the washout base were gone. Not broken off, gone. That was probably the sound I was hearing. Cleary I did not do a good enough check of the bolts on the head though I thought I put wrench to everything. Ordered parts, repaired, test hover in side yard, all is good.

Incident 3: yesterday out at the field it was windy, too windy to fly an unproven unfamiliar helicopter but I did it anyway. Flew awesome, no issues. Landed, hit throttle hold and the wind got under the decaying rotor and tipped it over. The right answer would have been to land nose into the wind and get on negative pitch faster to plant it but I have never had a tipover before in all these years so lesson learned.

So while I was convinced this thing is cursed since it was owned by a dead guy (so I was told anyway) I really had to take a step back and think about what was happening. I have not crashed this much in a long time so what was happening? Bad decisions, every time. So if you are having a rash of crash, odds are high it is you and not mystic forces or bad luck or whatever.

Pshaw! Clearly you have angered the heli gods. Pay a tithe you must. Nigeria bank account you will send to heh heh

Thanks for the reminder about listening to those voices that tell you not to fly when something doesn't seem right.

Yep if it smells like fish, it's not a day to go flying. Glad your not injured.
