The Goblin 500 took a major dirt nap Sunday morning! I had 3.5 great flights through it, and was on the 4th pack when it happened. Flying towards me about 100 feet out and 30 feet high, the Gobby took a sudden pitch down and also dropped fast. I tried up elevator and higher throttle to no avail. In just another second, it continued to pitch more and more nose down and might have been about 60 degrees nose down when it hit terra firma. Not a pretty sight. Tacoed the battery pack. Came home and did an assessment of the damage, and so far it is about $350. It would be higher than $400 but I already have a canopy replacement received as a Christmas gift from Tad and Becky. Surprisingly the boom and all tail parts seem undamaged. Pics to follow when I extract them from my cell phone and iPad later.

Taco supreme! |
Oh, Tad and I autopsied the remains and our guess is the swash plate ring failed, causing an unavoidable catastrophe. I researched HeliFreak last night and found many threads about the stock swash plate failing. Too bad I did not know about it before the crash! Oh well, let's move forward with a repair, and rise of the phoenix.

Ready for autopsy at home. Surprisingly no damage to boom and tail! |
|
Dirt in the motor. |
|
Busted swash ring |
|
Bent blade holder and spindle, maybe main shaft too. |
|
Lots of canopy damage elsewhere too. |
|
Both blades damaged enough to be unusable. |
|
Right main frame and battery holder cracked. LG and braces undamaged! |
I flew the Gaui X5 twice after the Gobby crash, and it was fine, so I ruled out (generally) the transmitter as being the cause of the Gobby demise. Also had 3 flights with the Sbach 342, all very crisp. Had actually another flight which ended in deadstick at the end of a long double spin. The engine died when I reversed the spin direction half way down. Made a safe landing on the sod grass just off the runway to be safe. Increased the idle by a few clicks for subsequent flights.
