Compared to this one: HobbyKing GA-250 MINI-MEMS Gyro What do you say ?

I have used both on my HK450GT helicopter. They both work great as long as you isolate them from vibrations very very good. So you can get any of them, go with what fits you best. I did not notice any big difference in performance in mine.

Does this gyro work on deltawings?
 shmuel 113 points
on delta wings each one of 2 aileron connect to a different servo. you can't connect one gyro on both 2 servos.but if you put 2 gyros each 1 on 1 servo it will work

Awesome little gyro. Just make sure sensor is exactly parallel to the main board and hot-glued in place. 4F5FF23E-9D66-4056-A6D7-B03DCC8FF32F

I have seen a few posts asking about the AVC AND NOR settings using the tx9 and have seen a few people complaining that they have no control in AVC mode (head holding). The settings have to be above 50. Set to these setting and i have found this gyro works very well and you can switch between head holding and rate mode with no problems using the switch. State ACT UPRATE AVC 068 DNRATE NOR 060 MODEL GY Make sure you have the other gyro settings on the gyro set up correctly too ,as the instructions.

can i connect this to the steering servo in a rc car
 shmuel 113 points
yes this way: the input of the gyro to the steering channel in the receiver.the output of gyro to the steering servo.the gain wire of gyro to 3rd channel and program this channel to 4o%-49% normal mode

The gyro is amazing. I used it in the road car model to manage and everything is in perfect order. I recommend this product for its sensitivity and price.

i figured for the price i couldnt resist trying one of these and i am not dissapointed this things works great just as good as my 401 futaba gyro you need to look at the mods section on this as i had to do that but the little time i spent doing the mod was more then made up for with the low price and great performance
