Default New RV Flap Actuator - New Product Intro



We are pleased to announce the introduction of our new RV Flap Actuator. We have been testing 3 prototypes in our RV-6 aircraft for the past 6 months with excellent results.

We consider our new actuator to be an upgraded version of the stock flap motor. It has the standard 5" stroke, but the motor stops when it gets to the end of the stroke. So if you've ever thought about installing flaps-up limit switches to stop the flap motor, this unit is for you. Additionally, it has an internal position sensor, so if you've been thinking about mounting an external position sensor to monitor flaps position, this unit is for you!

Flaps extension/retraction speed is about the same, as is the amperage draw of the motor.

If you're interested in learning more details, please visit our web site and download a copy of the Installation & Operating Instructions. We detail the steps that we took to convert our old flap motor to our new actuator in our RV-6. We've included several photos of the changeover.

We also think this unit solves any issues you may have had with "grease migration", a problem that has plagued many of the stock flap motors. Additionally, the safety-wire service bulletin that was issued for the stock flap motors is not required for this actuator, obviously because it doesn't keep running when it gets to the end of the stroke.

Please compare the price of our actuator with the stock flap motor, which just might be the best feature of our new product!

Let us know if you have any questions. Thanks!

well, I've needed to clean grease from my flap motor twice in 600 hrs. and probably due for my third cleaning soon. it seems I need to do it each 200 hrs. this may be an upgrade. is grease in the motor a problem with these?

Nice product Pat. Question; What's the temperature operation range and how slow it gets in very cold weather?

Hi Steve,

Well only time will tell for sure, but in our opinion there is no way for grease to get from the jack screw area to the motor as they are in separate compartments totally sealed off from each other. I'm only speculating here, but I think part of the problem with the old flap motors is that in many instances they continue to rotate after reaching the end of their stroke, which may be one of the causes of grease being forced into the motor. I, too, had to clean grease out of the brushes a few times!

Pardon my ignorance...so all RV's use the same 5" stroke for the flaps?

Vlad: Operational temperature: -25?C to 65?C (-13?F to 150?F)
Of course, we have no way of testing in the actual airplane in cold weather here in Florida. We would be delighted if you would purchase one of these and take it with you on your next adventure to the far north (and west) and let us know! We suspect that it would operate just fine! Good question!

The RV-6,7, 8 and 9 all use the same flap motor part number, ES-85615-157-1. (As indicated on "The List.")

The RV-10 uses a different part #, not sure about the -14.

Well this is cool. I installed I have to assume a similar unit in my -7. I have had good results with mine on a simple test bed. I opted for the dumb actuator with no pos sensing. I still have to turn a new end piece as the supplied one had a hole in it.



Hope this came up...
