Can I connect this gyro in a receiver that will feed directly with a 6.6V LiFe 2s?

On this gyro the one I got has some sort of yellowish plastic covering the switches. Does anyone know if that should be removed of should I just move the switches thru the plastic? What is the default position of the two switches as it comes from HK? Thanks for any help!!

use them in all of my cars. smooth and nice, and you dont need to connect the 3rd channel (gyro Sens.) cause it is perfect on default settings. Gyro sens. Only needed for drift car.

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
