I've just put a yellow K Bar on an Align Trex 450 Sport that I've had for some time. It's been using a ZYX v4, which flew pretty well, but now I'm moving most of my fleet over to the K Bar. The tail servo is a KST DS115MG micro servo, that is quite fast at 6 volts (which I'm using).
The yellow K Bar uses a digital 3 axis MEMS and a second MPU to emulate the older analog sensors, one of which is now end of life. So the gyro is a bit of an unknown, and this is the first time I've tried it on a 450.
The heli flew well on the default settings, but the tail wasn't as good as it used to be. Changing the gain just took it from wag to mushy, but it still felt odd, with strange kicks and the odd flutter, especially with puffs of wind.
The Accel setting had no effect from 55 to 75 and the P gain didn't help. I tried the I gain from 50 to 90, and that didn't help, but when I set it to 40 it was better. I then had to increase the precomp (currently 44, but I'll play with that some more).
William has offered to show some settings for his 450's that look to fly very well, especially with his excellent flying skills. I know he spends quite a bit of time getting his helis right and he has a lot of experience with the V Bar. This K Bar may however require different settings, due to the different sensor setup.
If anyone has a good working setup for a 450 then please share it here.
I've attached my current tail settings, but I'll play some more to see what's best.
