Just 103 Solo-X

////////SCROLL DOWN FOR AG CONTROLS AND FLIGHT INSTRUCTIONS\\\\\\

    The Solo is back, and better than ever!

The Just 103 Solo, an ultralight produced by Just Aircraft, was designed to fit the Part 103 requirements (Federal Aviation Regulation Part 103 for Ultralight Vehicles). The requirements for the Part 103 classification are:

must be used/operated by no more than one occupant
must weigh less than 254 lb.
must have a level flight top speed no greater than 63mph
must have a power-off stall speed no greater than 28mph

By complying with these restrictions, you are able to fly without any sort of pilot's license or medical certification, which makes it a great buy for the casual recreational flyer (you should definitely still take flying lessons first though).

The Just 103 Solo is a fantastic Part 103 plane; quick, sporty, light controls, extremely well balanced. It's more of a plane than you might expect to get from an ultralight aircraft. Perhaps one of the best ways of getting into affordable recreational aviation.

Well, the Just 103 Solo is back, as the 103 Solo-X, with new features, extras, and awesomeness!

The Just 103 Solo-X (experimental) is a prototype intended to be the second gen 103 Solo. Although the Solo-X uses the same Polini Thor 250 2-stroke engine, this 36 horsepower motor now produces greater thrust; through careful tuning and the addition of a 96” prop. This has improved the Solo-X's level-flight top speed from 63 mph to 79mph. This is a 25% increase over the original 103 Solo (this new top speed is also 16 mph faster than the Part 103 top speed restriction... but we won't tell if you won't).

The Solo-X has also been equipped with flaps and flaperons, further decreasing its stall speed and improving low speed handling. The Solo-X flies just as comfortably at 29 mph as it does 100 mph. The larger winglets decrease drag, increase lift, and lower fuel consumption, increasing the range. Another improvement is the plane's flight instrumentation; adding compass, altimeter, ADI, and airspeed indicator. The safety of this plane has been greatly increased by the installation of a four-point harness and a ballistic parachute. And just for fun, we added a smoke trail system!

The 103 Solo-X is scheduled to be available for purchase early next year. So if you're interested in affordable, simple, and seriously fun recreational flying, then contact us and pre-order your own Solo-X today!


Using the prop wash simulator, you can lift the tail section into the air before you've even started rolling!


The ballistic parachute will do an excellent job at preventing you from ending up in a terrible deadly fireball crash!

    Controls

All flight controls are standard.

 -Ag1- ignition, instruments

 -Ag2- prop wash simulator

 -Ag3- lights

 -Ag4- parking/hand brake

 -Ag5+[fire guns]- smoke trail system

 -Ag6- ballistic parachute

 -Ag8- tail wheel turning

 -VTOL- flaps

 -Trim- trim

I recommend deactivating the prop wash simulator (Ag2) after take off, as it reduces realism of flight characteristics during normal flight

    STOL Instructions

For best STOL take off:

 -1) activate Ag1 (engine), Ag2 (prop wash), and Ag4(hand brake).

 -2) extend flaps fully and throttle up to 100.

 -3) when engine/prop has revved up all the way, release Ag4 (hand brake).

 -4) when tail section lifts off, or at 20-21mph, pull up hard.

 -5)once airborne, retract flaps (they are very aggressive) and deactivate Ag2 (prop wash). 

For best STOL landing:

 -1) reduce power to 25-30%, move trim slider all the way up (pitch down).

 -2) slowly extend flaps as the plane slows and descends (on final approach).

 -3) plane should fly level with flaps fully extended at around 30 mph. 

 -4) activate Ag4 (hand brake) and reduce throttle to 0-5%, pitch up.

 -5) let plane slowly glide to the ground while pitching up, at touchdown kill throttle and apply normal brake.

    Features

 -custom airfoils and control surfaces

 -functional instruments (ADI, flight time counter, altimeter, compass, airspeed indicator, fuel gauge, tachometer)

 -true to life weight, size (length, wingspan), speed, handling (I think...I hope...), and horsepower

 -detailed cockpit and engine

 -functional controls

 -unique livery/lettering

 -smoke trail system

 -stable and well balanced (no autoroll, plane flies straight and level at 100% throttle, 78mph, without any trim adjustments)

    Credits

 -ADI (attitude direction indicator) built by @ChiChiWerx
 -Digital flight time counter built by @Tully
 -Smoke trail effect created by @MrSilverWolf
 -Thanks to @Chancey21 for feedback and advice
 -Thanks to @jamesPLANESii for feedback and advice

-And thanks to @tylerdeveneuxmusic for final testing. If you haven't seen his work, you might want to visit his profile page here and check out his awesome car builds.

Okay that's all, thanks to anyone who actually read this whole description lol. This build is technically an update of an old build, but I put more effort in than a regular update. I'm happy with how it turned out, I hope you like it too!

Happy Flying

    @Hyattorama would you like to check out what I’ve been working on lately? I haven’t built much in a while, and i’m kind of getting back into it.

    I was patient and took my time, instead of rushing to get it posted in 48 hours like I always do... so I am pretty proud of myself and proud of the outcome, yes, thank you :) also a personal best upvote-wise, which I know is just a number, and my vanity shouldn’t be important. But also it hopefully means that some people enjoyed playing with it, which I think is important, and does make me feel good. So short answer is yes, I feel plenty rewarded. Probably more than is warranted but I’ll take it! Lol

    There’s tiny jets attached to the elevators and rudder and then one jet engine turned backwards to counteract their net forward thrust. So then when stopped or at low speeds it acts like there’s prop wash. I couldn’t get it calibrated just right, so it causes the plane to be too maneuverable during normal flight, so I had to give it an on/off switch. @ACEPILOT109

    Prop wash? How did you do that? @Hyattorama

    Haha yeah that is a bit of a problem with high part counts... it flies pretty similar to the first one apart from the prop wash and flaps.

    Yeah I changed the descriptions on the other builds. So I guess it’s okay..

    @Hyattorama Idk up to u. I guess the rule of thumb is just give him credit for something that he built.

    Oh yeah haha totally!! It’s such a cool plane. I’ve learned a couple tricks since then and I always wanted to do a little something more with it haha. @ACEPILOT109

    @Hyattorama Nonononono. Timer was built by Tully like 3 years ago. I used it with his permission on something 2 or 3 years ago but i think i deleted.

    Ok. Well on the beacon light part, you can program the flash pattern. I can’t remember the name of the field you change atm, but the values for the flash pattern is written in seconds, like [1,1] would be a simple one second on, one second off. And [1,2,3,4,5,6] would be one second on, two seconds off, three seconds on, etc. And at the end of the string of values, the pattern starts over. So for each of the seven beacon lights in each of the seconds place, ten seconds place, minutes place, and ten minutes place in the counter, there’s a different program written specifically for the position of each beacon light in each place, it flashes out every second between 00:00 and 59:59. The timing of the programming in the game isn’t perfect, so the digits start to get out of sync after a minute or two, so first the seconds place goes wrong, then the ten seconds place goes wrong and so on and eventually it’s all just a garbled mess. But it’s still quite an impressive SP invention/design if you ask me :)
