Well I crashed my Raptor 50 today. My flying site is near a canal. Was flying circuits and for what ever reason the wind starter pushing me sideways and off course. I tried to bring it back tail in, but it just seem to not want to return. It almost seem like it lost the signal. The tail began to blow out and heli began to descend. I remembered some heli friends of mine that said if it is coming down hit throttle hold to reduce the amount of damaged. So I did. The miracle is that it was coming down near the canal and at one point I thought it went into the canal. I began my search and by a miracle, there it was half in the water and half out. Just few more inches and it would have been gone. Now that's is miracle. Gonna cost me about $100.00 to get it flying again. Could of been $800.00

That's cool that you managed to save it from the canal. Fix it and fly again!

Man, I miss the eighties.

Which half was in the water? Was the half that was in the water completely submerged?

The part with the electronics in it. The receiver for one was completely submerged. Just a few more inches and it would have been swept away by the current. At first when I went looking for it, I thought it had gone in the canal and was submerged. Then I saw one of the blades sicking out of the mud and weeds.

I torn it down and it looks like flybar, main blades, pitch servo arm and boom were the only damage. However I have decided to go ahead and upgrade the rotor head from the stock plastic head to metal and replace all ball links. The swash also looks a little worn so I am replacing it at the same time. I am also going to tear the engine down and check the bearings. I have had the heli for over 2 years and this is it's first crash. This crash could of been prevented it I would have just taken the time to learn nose in. When the wind started pushing it away from me and the nose came around I freaked out. It is time to work on nose in and flying in both directions so the next time this happens I won't freak.

This is just my opinion, but *I* would get a new receiver (and any other electronic equipment and servos that had been in the water. While you may be able to disassemble the electronics and let them dry out for a few days and have them work on the bench, would you really trust them in the air after they'd been submerged? I know it's an expensive proposition, but to me the peace of mind is worth it.

I have the 8fgh futaba radio that i got a few months ago and have been using a 7ch receiver with it. It came with and 8 channel receiver. I will be upgrading to it for sure now. None of the servos came in contact with water. They are easy enough to disassemble and clean out though. The lipo battery may have got wet also. I might better test it out to make sure it is ok, before using it again. Other them the battery and receiver are the only electronic devices that got wet. But I will be sure to verify everything thoroughly before leaving the ground. I do not want a repeat. Thanks

It flies again. Tore the engine down it was full of canal water. Both the header tank and main tank had canal water in them including the muffler. The engine bearings were not in good shape, so I replace them with new ones. Upgraded plastic rotor head to metal. Spindle was bent. Replace it. Replaced carbon blades. Replace pitch servo arm. And replace boom. Everything else was ok. Setup up on bench.

First test flight. Tracking dead on. Yawing to left, adjust tail control leakage in normal mode. Switch to heading hold. Just a little more trimming on aileron.

I believe it flies better then before the crash. The bearings in the engine must have been going for a while. The engine is much smoother and seems to have more power then before. The little burp I used to get between idle and mid stick is no longer there. The sun is shinning and the air temp is 77 degrees F and wind out of the northwest at about 10 mph. Perfect, time to fly!

Test flight #2. Hovering to verify settings. Nose goes straight up, tail straight into ground. What just happened. Can't believe it. Take machine to bench to tried a figure out what happened. It seems that when I put the new metal head on I forgot to properly tighten the phasing ring. He came loosing during flight and the rest is history. Boom, spindle, main blades, flybar, boom supports. That really sucks.
I am think after test flight I was going to check everything for tightness. My mistake won't happen again.

You should! Electronics are not damaged by water - in fact the last step of Mfg. is usually a water wash! Resultant corrosion can be a problem, but he got to it immediately, so a good rinse with distilled water or alcohol should remove any trace residue completely.

It wasn't the electronics that caused the crash. The phasing ring on the new metal head I upgraded to came loose. This is what caused the crash. It was my fault for not properly tighting the ring. There was no doubt when I was checking to see what happened. I could turn the ring easily. I could just kick my self for it. That was the last set of Thunder tiger carbons I had. And the heli was so smooth in the air after the rebuild. I still can't believe it. It was a dumb mistake on my part. It won't happen twice. It better not!!

I wouldn't get anything wet intentionally. Sounds to me like you had a very minor crash with a little bit of luck thrown in Get it fixed and get it in the air.

It's a complex, costly, glow powered anti-gravity machine!
