It was one of those days that really takes it out of you today... I flew a little and went home 🥵

I did get some replacement servos ordered for my PA Ultimate and batteries for my Baby Ape II. I've still been completely slammed at work and just flopping into my chair afterward until I fall asleep, so I haven't worked on any projects lately 😭

In a couple of weeks, it'll either slow down considerably or get WAY worse. Either way I'll tell you about what has been going on 😂

Edit: Saw some guys on FB talking about flying tomorrow. Maybe I'll take a couple of small birds out to goof around with. Maybe the big C130 too... 🤔

Edit 2: I lied about projects. I forgot I'm printing a new Nemesis right now 👍🏻

Edit 3: Also I want to throw my Qidi Xmax3 out the window 🫩

Yo! How's it doin'?
I've been up to something super weird lately... You know the conspiracies going around that the mighty f22 raptor was reverse-engineered alien tech?
Well... In this enterprise I have managed to reverse engineer some alien tech and make a hybrid alien-fighter of my own redesigning (just a few unearthly tweaks and modifications of the FT 22 to my liking).

Lo and behold... The alien-hybridised-alien-fighter-drone with key changes from ft22 being:
-sharper nose and smoothed down cockpit to be more fitting for alien A.I.
-made the wing more uniform like the yf23 or f35 but higher sweep
-higher sweep intake angles
-heavily modified elevons and fins because... Aliens!

All that's needed is to do a bit of repainting to make it look like the first pic (glowing alien runes, energy conduits running like veins, anti grav generators etc) ... More to come 😁👍

Experimenting with F-22s (I use a different base design) is one of my favorite things to do with RC 😎

Hello! I recently bought a tinywhoop, and for some reason the adjustments tab on betaflight won't save. Anybody know whats up? Thanks!

Have you tried changing settings through the CLI?

How about rolling back or forward to a different firmware?
I haven't messed with the CLI much, I'm not sure how it works. I also haven't tried different firmware versions. Do you know where I could find those?

It would depend on the specific FC you're using. It's likely that the manufacturer will have at least the latest (which it sounds like you've tried), but they may have older versions as well.

If not, you can try finding it in the firmware update page in Betaflight. You'll need to make sure all of the options you use are selected and everything is CORRECT before doing so though!!

Here's a link to Oscar Liang's site which is a great multirotor resource. This is CLI stuff. It looks intimidating but it's not so bad once you use it a little. Make a change, then see if it saved in your adjustments.

Thanks for all your help!

Have you tried canards, leading edge flaps?
Fixed canards yes, leading edge flaps not yet.

Canards give you an almost instant turn but dumps all of your energy. Fun in combat if you have a torquey motor with a lot of thrust 😁

The simplest and most effective mod (for the design I use) is counterbalancing the elevons. Less stress on the servo and WAY more control.

I'll eventually get to working canards.

ETA: RCSuperPowers did a ton of testing many years ago with lots of different foamy jet designs. His videos are still worth watching.

If you install a servo to control each canard and setup a second set of elevons (radio) hooked to run the canards, you now have 2 sets of ailerons and 2 sets of elevators to do your roll and pitch. On another plane, not only had that setup, but added 2 motors/props on back elevators (now you have differential thrust). The plane acted like it was on crack!!!! Destroyed itself due to very high stress.

I love it! That is the joy of building with foam board - let's try something wild. It only takes a day or so (ok, maybe longer) to build rather than months and no tears when it destroys itself.

If you cross a pair of pushrods to the canards from the elevon servos you can have elevon roll and pitch without the extra weight of two more servos, too 😉

Hello! Does anybody here have experience with ultralight design/building? I have been looking at building one for as cheap as possible. Hope your days great!
