Flap motor retrofit

I got what you are asking now. I don't know of a standalone "controller" as I have a Garmin system that includes that functionality.

Here are a few pics. Remove rivets that hold the old bracket, drill four new holes each side of tunnel, rivet in new bracket in new location, install motor. Of course, a bit of prepping and priming... Took about 3.5 hours on a not yet flying -10 that was already accessible. As previously mentioned, no big reason to change an already flying -10.

Flap Motor Retrofit instructions Corrections OP-65: RV-10

1) OP 64-01, Figure 2, an 8th rivet needs to be removed (plans indicates 7 rivets) - the one to the left of the shaded area is the 8th rivet that must be removed. The hole is used for riveting one of the holes on the new bracket.

2) OP 64-04 Figure 1, Two washers - NAS1149F0563P - are needed under the castle nut in order to remove the end play. Without a second washer, the castle nut bottoms out on the AN5-25 bolt before end play is removed.

3) OP 64-05 figure 1, The 6x NAS1149F0332P are the thin washers. They bottom out on the bracket/nutplate before they are tight. They need to be replaced with "standard" thicker washers (don't know the part number).

Greg/Scott -Hope you get this and pass on.
Cheers

Thanks for posting your installation photos and feedback on the documentation errors, I will push this information upstairs to Engineering. I expect that OP-64 and the kit plans pages will be revised sometime in the future.

As many of you suspect, most of the Engineering staff is currently busy with pre-OSH preparations.

I noticed that the potentiometer in new retrofit flap motor for position sensing calls for a 5v input. VP-X supplies 2.5v for this (pin J1-19) as far as I can tell. Has anyone completed installation with the VP-X with position sensing? Any problems?

I put a second NAS1149F0563P under the head of the bolt. I also added one NAS1149F0532P (thin washer) between the right bushing and the right bracket to take up most of the slack between the motor and the brackets.

My kit had a random mix of thick (0363P) and thin (0332P) washers. I went with all thin washers and they didn't bottom out. I wonder if you received the correct length bolts in your kit.

My third-hand kit came with the TCW Intelligent Flap Controller, which uses timing instead of flap position. I'd prefer something that uses flap position. Is this a job for an Arduino Nano? I'm not that guy - just asking.

What does the new flap switch look like with this retrofit kit from Van's? Prob gonna do this to my flying 10. I use just a momentary toggle right now with no limit switches in the system, just eyeballs.

I use moment switch and eyeballs.
Advantage is unlimited possible positions for flaps.
Disadvantage is unlimited possible positions for flaps ….

Same switch
