because i just took the sensor without amplifiers the sensitivity is bad!

the bord had apparently an amplifiers just straight after the sensor mount in instrumentation amplifier (don t know the exact name in english!)

the sensor shows me very poor resolutions i ll probably need to buy a rc gyro and mesure the pulse between 1ms and 2ms and integrate it (maybe more acurate???)

i have to finished this project anyways so you ll see me later on i think!

thank's all for the moment! and again sorry for my english (not very proper)
Sure, you could amplify the output with a simple op-amp circuit, no problem there, a hundred different ways to get a better resolution.

Signal refresh- that's probably the one going to servos, every 20ms, the capability to read the sensor with a PIC is far greater, good enough for what you're thinking about. I'd roll with the project until it worked, I wouldn't get rid of it yet.
Your english is good enough for me, most of the time anyways
