There are two elevons which use two servos as far as I can see in the build video.Where does the third servo hook into?

Thanks.

Mine only have 2. The only thing I can see needing a third for is if you want to add a bomb drop..

Thanks ttabbal.
I will order some spare servos just in case of crashes.
So two servos for two elevons should be good to go.

All these parts are out of stock on Hoby King site.Will just have to wait for them to be in stock again.

Yeah, not sure why the video would have said 3 servos. It's always better to go by the pdf instructions provided on the website. They're always more up-to-date than the videos.

I did my first LEDs with the lights facing out, and it looks great, but honestly, it's a bit TOO bright. After flying for a couple of minutes, it starts messing with your eyes, and things get blurry or jumpy in your vision. It's weird. A couple other fliers have said the same thing.

From then on, I always install them with the lights facing into the foam. It's plenty bright to see at night, and the foam diffuses the light really well.

Lee prefers to install lights after the entire build. Personally, I think it's easier to put them in before laminating, and use my foam-melting soldering iron to melt a shallow slot for the lights. No slicing or patching laminate you've already ironed on. I've never had a problem with the iron melting the lights under the lam or anything, since you probably shouldn't let the iron sit in one place long enough to do that kind of damage anyway. I've done about 5 or 6 planes that way, and I put lights on everything I build, now.

I sometimes put a bomb drop in using the third servo but the elevons only need two servos.

There are many ways to do the lights. I am lazy and also have retrofitted several planes that were already built and covered with laminate with LED lights. I now have 8 night flying planes.

I like to cut a slot, on the bottom of the wing, through the laminate and about 1/4" deep in the foam and put the lights facing in into the slot and then put a strip of clear packing tape over the lights. The two big advantages are the lights are easy to repair if broken and if I ever retire the plane the lights are reusable.

We see some extreme light set ups. Go for it if you want to and send us some pictures.

This is a video of the Albatross with the lights facing into the wing. There are no lights on the top of the plane.

So what's the best streamer material to use for combat on the Assassin? How long, and do you attach one to each wing tip? I have that orange plastic stuff for construction but I can see that getting wrapped up in a prop.

Crepe paper works but I like the 1" plastic construction ribbon at Lowes. It pulls easy and doesn't tear so easy taking a better hit to tear it.

I will pull a single streamer more often than a double streamer and often have it 30 plus feet long.

Our club did quite a lot of testing - 2, 20' long Black paper streamers were our favorite.
It's VERY satisfying to see the cut portion drift slowly down after a cut and no clean-up is necessary because they dissolve after a good rain.

The downside is they require a strong motor to pull - the rewound 2812 works perfectly but a stock 2812 with 2, 20' paper streamers is a handful.

The plastic stuff is easier to pull, but it's harder to see drifting down after a cut and makes a mess on the ground that has to be cleaned up afterwards.

I think "good rains" might be a lot more common in your part of the country than Orem, Utah!

Yea, and at this time of year the rain is of the solid white type

By the way, we attach our streamers to the wing tips with clear packing tape. We use the same tape to add additional streamer material to the short streamer after a match.

Thanks guys, can't wait to try it. I've pulled a 100ft streamer from my PZ P-47 before, but no combat.

Think I'm going to set up a WidowMaker for FPV flying. Trying to get the best of both worlds - light enough to glide a ways and fly smooth for longer duration, relaxing flights which I love but also get that nice sweet speed that I got from my lower-quality PopWing, around 60 MPH.

Going to be running basically the same setup on my WidowMaker as my PopWing (not using anymore): 1360 kv 52g brushess outrunner, 30A ESC with heat sink, 7x5 prop, 11g metal geared servos, 1300 mAH 3S 20 or 30C packs, FPV cam/vTX/filter.

Might try a 7x6 prop though just because

Should be lots of fun!
