Hi
Got a raptor 90 with a C-Spec 91, has anyone setup a CarbSmart on one of these? Was planing on using a Hitech hs-81 servo, any ideas on servo and sensor placement, Thanks Charlie

I do not have a carb smart yet but per a review by RC-heli, you do not need a great servo, even a mini or micro servo can do the job. As far as the placement of the sensor they said to put it in relation to the combustion chamber because that is the hottest part of the engine. The combustion chamber (between bottom dead center and top dead center) is just below the head.
