Hi all, noob here looking for some help please.. i git a 450 DFC off ebay, but MRS unit was no good so fitted a K-bar mini..never done one before,,

yeah thats what i figured but i dont know how to fix this in VStabi . any ideas ?
i nothing relating to giro in settings, except mounting position..which is ( i guess) how it sets the giro ?

shouldn't smoke, I'm assuming your using 6v or less power supply

ummm.no...im using 3s batteries ..im confused ..its a Trex 450 Plus DFC Rc Helicopter BTF but i googled this servo and it says Rating voltage 4.8-6.0V..hmmm
Is this because im using a Kbar ?
does the GX3 mrs drop the voltage down ?
or does this copter have the wrong servos fitted ?
cheers

if your using via the esc bec voltage will 6.v or under. if your plugging 3s pack straight into kbar you have a problem

What BEC do you have fitted?
You're not wiring the electronics directly from the 3S battery... are you?

(never mind... I typed too slow)
