Okay guys, I'm stumped. And when I can't figure it out, something has to be wrong.
Lets just start off saying that I"m not happy at all. I put two helicopters in today, thankfully this one, is just a front tail gear.
Since I crashed the crap out of my SE V2, I decided to go ahead and get the 450 Pro V2 in the air since it had not been flown in a very long time. This helicopter has the AR7200BX on it with the latest firmware. And it flew fine the last time I flew it.
Here is what happened.
I took it outside to do another shake down flight while the mobius charged up, then I was going to shoot some video that I have been needing to shoot for, oh, about 4 years lmao. So I take it outside and I plug it in and let it do it's thing. Once the gyro was happy, I picked it up, checked ALL directions and everything was perfect.
I spooled it up after centering the tail blades (then returning to HH mode) and put it in the air. Pretty much, I was getting back to basics (did I ever leave?) and I was doing some side in hovering. But I was doing it as I have in the flight school. First, go to a 45º angle each way, then go full side in.
I did the 45º then I did the full left side in and was holding it over the pad, then I rotated around and was in a full right side hover. That is when, WITHOUT ANY STICK INPUT AT ALL, this thing, after a complete stop in right side hovering, goes right rudder to a perfect nose in orientation. I TOUCHED NOTHING! It's like the gyro just moved it there like I told it to do so. I'm talking a perfect 90º rotation to the right.
Fine, I held it there for about 5 seconds and rotated it around (to the right, if it matters) to a tail in to start all over again. Then, I landed but the tail was twitching and I decided to go ahead and hit throttle hold and land it in the grass.
I know, TT tail and grass. But I have the black gears, I checked them at this time and everything was PERFECT!
So I spooled it up again and thought, maybe the head speed is too low (I was only running 65% head speed, which is great for this helicopter). So I put it back in the air, and just in case something happened, I went up about 40' into the air and hit IU1. All hell broke loose when I did that. A complete, out of control piro that I could not stop with any kind of input.
At this time, I had no choice but to hit throttle hold and try to save as many parts as I could This time, I was in a little taller grass though (just mowed parts of the yard).
When it landed, I heard the sound that no one wants to hear, grinding gears. I thought the cones stripped, but NO. The .06 gear that meshes with the auto gear stripped!
So I have checked every single setting on this gyro and the transmitter. I have watched the monitor menu for quite a long time and the rudder never moves, so this is not a transmitter issue. I have checked the gain (again, programmed into the gyro as set in Tx) and I'm showing a G on the gyro, and that is about right seeing as I have +45% on the gyro gain, so that is working.
The only thing left is the tail servo, but nothing has changed. I have not crashed it, it has not gotten wet. In fact, this is the ONLY helicopter aside from the 130x RB that has ALWAYS been in a case.
It just makes no sense to me that this thing would just wig out on me like that without any reason. I'm starting to think I should just stop flying, and stick to how to videos... I seem to be good at videos, but I seem to suck big time on flying anything...
so what are your thoughts on this?
