Hello folks,
I just installed a different gyro on my blade sr. An ms-044 heading hold gyro.
Now i have excessive tail wag. It wag almost ninety degrees, actually more like a "kick", but repetitve like a wag.

This gyro worked flawlessly on my mini titan before.

I tried to play with the delay and limit by adjusting it to full and low, i've also played with the gain setting all the way down to two to three percent and it still kick. I've also tried to play with endpoint adjustment on the transmitter. Still no help. I haven't tried playing with the ittle pot on the esc yet. Do you think this will help?

I dont think i have any problem with vibration or douple side tape, as this problem doesn't appear to be a vibration problem.

I'm out of ideas, can you give me som pointers.

Thanks

Tam

I know about the belt tail mod. At $80 for the mod and it just make the heli more fragile, and more parts to fix in a crash.
I'll charge up the battery and play with the pot on the esc and see how it goes.
Also, i'm having a difficult time finding the manual for the e-flite 2in1 esc. Does this esc need to be calibrated, how does it learn the end points for different transmitter, can anything be programed on this thing?

just out of giggles i decided to tape back on my eflite gyro to try out and it stoped the wagging.
probably this ms gyro is very sensitive to vibration or just overly sensitive all together. i have also de-cased the ms-044 gyro and use shrink wrap on it to save some weight. perhaps this is what has added to the overall sensitivity of it.

it is much more flyable now, but the wag is still present. i want it gone. perhaps i will start to play with revolution mix and turn off heading hold all together.

my friend just crashed it not too long ago. this cold weather really make the plastic parts brittle. it literally exploded on impact with the earth.
i think i got pretty much all the parts to fix it up.
well, except for the blades. stock blades are too slow for me. got any sugestions?

oh, about the tail twitch. nope! my fifties and nineties hold a lot better than this.

yes, the ms-044 does require a power reset for the new setting to take effect. i'm aware of this. because the setting is being read only at boot time. this is a convinient feature actually, usually for any onboard electronics that uses a switch or mechanical pots to make adjustment. this is so incase the vibration should cause the mechanical pot or switch to fail durring flight, the setting will stay intact throughout the flight, and the failure devices will be observe on the next boot up.
however, the gain setting which when being controled by the transmitter, does not require the power to be cycled to take effect.
