I believe they will just be in the box for you to install. That was what James said in the install video. Alpha had said that they may be installed for you or not but I think they decided not to. I think I would rather put them in myself than a warehouse worker or someone else... Then you get the two old servos for spares too.

Originally posted by nuts-n-volts View PostI've said it before, and I'll stick to it. These crashes have everything to do with being way too nose heavy and most having the linkage in the outer hole on the servo (not enough torque). And with the elevator servos being less than up for that task. These servos are over extended if not set up correctly. That's exactly why Motion/Freewing just put out new upgraded servos to all who bought/buy this plane.
The reason I'm sure these crashes were caused mostly by being nose heavy are two things. First, the 3 battery bays are a bit confusing. If you read the instructions, Freewing recommends to put the forward battery on the hump, not in the forward bay. If you're not reading, it would be very easy to miss, and that big forward bay looks pretty inviting. Second, all the crash vids show pretty much the same thing. The pilot has control - roll is there, but pitch is sluggish in up with nary any down used. Too much roll ends up with a substantial dive that, as speeds builds, cannot be pulled out of. The servos with incorrect linkage are over-tested.
Use the new replacement servos just shipped with correct linkage hook-up and I'm sure you'll be fine. If you still feel that they are inadequate, replace them with even better servos, as some have already done. I will go this route as well and then move the new replacement servos to the flaps. Beefing up the elevator linkage is something I always do on these foam jets. They are pushing the loads on the equipment and we/they must recognize these issues.

Swapping genders is problematic since it would break compatibility with all previous attachments people would like to reuse
True, true, and true.
Another reason why we mount the male tabs on the wing on all our aircraft is because the male tab piece is a single narrow ~1mm blade with a shallow apron and is thereby much easier to install into the wing without compromising the foam. The female slot piece, by contrast, is significantly wider --the width of the pylon itself, as seen in your photo-- and would require much more foam removal if mounted on the wing side.Live Q&A every Tuesday and Friday at 9pm EST on my Twitch Livestream

What the heck!!?? And a great surprise ............................. I just got notice that my Mig is about to be shipped. I ordered from the second batch that is due early October. I guess there were some cancellations?
Alpha .................. It's OK, you don't have to phone me. My feelings won't be hurt. You have enough stuff on your plate, like dealing with those who get their feathers ruffled when they think you're not going to call them. I'm on top of this whole servo and servo hole situation, plus a couple other things that will get this plane in the air safer.

I can tell you based on the sample set at my field quite a few just toss a battery in with the thought that there is only one place to put it so the balance must be right.
Same people don't know how or to do a range check or to even set throws. And obviously there are those that think all pushrods go in the outer holes.
Originally posted by xviper View PostSo, if a person were to get confused about the battery trays and didn't really read the recommendations about using the one on the hump, resulting in a plane that was very nose heavy ..................... Don't they actually test the balance before going up? And knowing that it didn't balance correctly, why do these people still fly the plane? (I know, gotta ask them.)

Man, I've been so busy designing decals and replacement fins for the missiles, I completely forgot that I still needed to install the RX, program the CenterBurner, calibrate the ESCs, tidy up the wiring, and set the CG and throws. And I plan to maiden tomorrow morning. Working on all that now. With a pair of RoaringTop 6S 5800 35C packs in it, I have one in the back and one overhanging the front of the top shelf by 1.25" and am sitting right on the CG marks with gear down.Pat

I find it astonishing but accept that it does happen. These are the same people who after they crash, can only say, "I don't know what happened. Must be cellphone interference."

That would immediately cause the jet to enter a negative cobra.
(I mean, that's not what we're seeing in the videos, for sure).

For those wanting missile decals and 3D printed parts, I'm putting the finishing touches on everything this weekend. Unfortunately, I'm out of town all next week to attend an event in St. George, UT. When I get back, I'll post up details on pricing and ordering.
Here's a sneak peak at the decal set:
