So we've been thinking about trying the new RV-10/-14 flap actuator in an RV-9 because the -9 wing and flaps are much the same as the -10/-14 and we thought it would match the flaps aerodynamic load better. This is our larger, more robust actuator that we had originally designed for the RV-10.
My friend Tom Savrda is building an RV-9A and wanted to try the larger actuator out. So we took a look at the -9 configuration and the larger actuator actually fits pretty well. The biggest change was moving the mounting bracket about 1 1/2 inches further back than the stock location to allow for the additional length of the new actuator. You can see from the pictures below the original stock location and the new location. The brackets could have been made with 0.063" angle but all we had lying around was the 1/8", but it worked well. We were quite pleased with the fit. The stroke length is the same as the Van's flap motors so nothing changes there. The actuators have built in limit switches which stop the motor at both extremes of the stroke. Also, they have an internal position sensor which can be fed directly into your PFD for flap position indication.
So we are now recommending the RV-10/-14 actuator for RV-9s for those interested in upgrading your flap motor.
