Recently my Raptor 50V2 crashed because someone turned on his transmitter on @ the same channel. I`m now looking at building the heli back together but I`m not sure if I should replace the GY401/9253.
Both Gyro and Servo look like they work great, and haven`t had a real beating in the crash. Even the gears in the 9253 are A-ok.

So should I use this combo again, or do I risk Failure in the near future?

Any experience on using a GY401 after a crash is greatly appriciated..

Richard


ps. If any of you did have failure`s after a crash I would really like to know....I`m going to upgrade every possible item, so I hate to see it go in after a few flights.

Was the gyro mounted on the rear shelf? If so It's probably OK! I've put mine in a few times and the gyro's going strong. If your worried that much about it, send it in to Futaba to get looked at. They'll test it and evaluate then you can feel safe flying it again.
If it seems to be working fine on the ground chances are its OK!

I would love to send it in but I live in Holland and I got my 401 from heli-kraft... And there is no checkpoint for gyro`s in holland, except one guy that does that but he is like 80 and doesnt look very reliable (I don`t think he even know what a GY401 is....) He is the official Futaba rep. But I personally don`t trust him.

Yes the gyro was mounted on the rear, but I`m only trying to find out of there were more failures after crashes....

Hi,

recently i let the futaba repairshop ( in holland ) check my GY401 with servo, they replaced the sensor, its works fine now.

My local hobbystore ( antwerp helicentrum ) works with that shop, i send in the past diffrend recievers and servo's to them, they do there job fine. So you live in holland.... ??

If you want more information.... contact antwerp helicentrum, with a little surfing you can find there site on the net.

Kind regards

Chris

gy401 crash

I have crashed my C-30 five times and still have a good Gy401/9253.The servo is boom mounted, and the gyro seems fine as it came out unscathed. One crash fell 150 feet. I have worried about it but have flown three gallons of fuel and still seems fine.

I have seen many GY's go through multiple crashes (like 10 or more). Unless the case is cracked, or it acts up just use it. If you bought it from helikraft, US Futaba won't service it due to the old grey market stinko.

The general advise of sending stuff in for checkup is good advice. I send my stuff in every couple years, and any receiver involved in a crash however minor gets swapped out and sent in for checkup regardless. The gyros are tough as nails and use suface mounted devices with internal damping/protection.

Generally when I've seen gyros fail, they tend to go hard over to one side as soon as vibration starts when the heli spools up.

I have too many crashes on GY401/9253, not much check, just fix the bird and fly again!

Given the construction of the silicon sensor used in the 401, I'd have to say that after a crash it should either work or not work. The PCB in the 401 is also quite thick and well supported by the case, so if the case is not cracked then the PCB and sensor should survive.

One thing to watch out for after a crash is the gyro cables, especially if the frames brake up sending the gyro and the Rx in opposite directions, putting strain on the cables and possibly causing the strands of wire to break internally. I've had this happen to me after a crash and it's difficult to find (unless you X-ray the cables). Broken wires usually cause intermittent problems so it may not be immediately obvious. Best way to test on the bench is to pull, shake and twist the cables around and monitor the tail servo for any glitches.

I too crash often and check the Gyro to work... If it doen't it's broken, if it does then it has always works for me.

If I was really worried about it causing another crash, I would send it to get checked....

Good Luck
