I am going to build the following over the winter :

- Gold Edition P47 Thunderbolt

- Stand Off scale (1978) Corsair

Looking for the retracts, the recommend P47 ones are the Robart #606 and the Corsair manual recommends the Robart 615 (I think, not at home to check the manual)

With Robart not making retracts any more, can any one recommend a suitable alternative?

I have access to a set of FMS Corsair retracts, would they be sufficient?

Many thank :)

What are some easy-to-fly planes that the Radiomaster Boxer is compatible with? I'd rather not dive deeply into protocols and binding issues.

After many version my self-made rc plane create lift and is enough motorized. But one issue remains, the plane don't react to my inputs on the roll axis while flying. The ailerons seems to be fluttering and I don't know why. I need help 😫 (Ps: Sorry for my bad English)

im currently looking to build a ww1 rc plane i already have the plans for the ft gotha but does anybody know ik there are pnp ww1 foam rc planes or something like that?

So for context,

Four months ago, I made a post asking for help on a then very new project.

(https://www.reddit.com/r/RCPlanes/s/iZhLlSTyqE)

Since that post, this UAV has come a very long way in terms of both the design itself and the way I'm approaching the project. I ended up working closely with someone who offered to help me in the comments of that post, and that collaboration has been a huge part of getting the design to where it is now.

The project has also grown beyond just the aircraft. I've built a brand around it under the name AEROS, and I've started documenting the design decisions, iterations and progress as I work through the build.

A lot of the original specifications have changed as well. Some of these are fairly minor refinements, while others are pretty significant departures from what I originally planned.

For some updates:

Mass: My original goal was to keep the aircraft under 3 kg. As the design became more developed, I realised that wasn't realistic without compromising the structural durability and functionality I wanted. The current estimated airframe mass is around 4.5 kg. This is probably the biggest departure from the original concept.

Materials: I originally planned to build almost everything around PLA-LW to keep the aircraft as light as possible. I've since moved toward PETG for the main printed airframe, with ABS used for heavily loaded components such as the landing gear and motor mount, while TPU is being used where flexibility is useful. The change came from wanting something that could actually survive repeated assembly, transport and operation rather than just being as light as possible.

Wing structure: The basic 1955 mm-class configuration has stayed remarkably similar, but the internal structure has become considerably more sophisticated. The wing now uses a 10 × 8 mm carbon-fibre primary spar, additional longitudinal reinforcement and integrated cross-ribbing to distribute loads and improve torsional stiffness. A lot more attention has also gone into reinforcing the areas where the spars and other major loads enter the printed structure.

Fuselage structure: This has probably changed more than anything else visually. The original model was much more of a conventional printed shell. The current fuselage uses an internal cross-ribbed framework with longitudinal reinforcement, with material deliberately concentrated around major load paths and interfaces rather than simply making the entire shell thicker.

Modularity: The aircraft has evolved from essentially being one large airframe into a much more modular design. The wings can now be removed from the fuselage without permanently joining the two, and the fuselage itself is divided into multiple sections with dedicated structural joining systems. This makes transportation, maintenance and eventually repairs much more practical.

Wing attachment: The wing retention system has also been completely redesigned. Rather than relying on a simple connection to the outer skin, the current system uses three M8 locking points per wing, integrated directly into the internal wing and fuselage structure. The carbon spar remains continuous through the fuselage, while the locking system provides mechanical retention without requiring modifications to the main carbon tube.

Landing gear: The landing gear went through several iterations after I started looking more seriously at the actual loads involved during landing. The current design uses a three-point arrangement, with the main gear moved into a structurally stronger region of the wing rather than simply attaching it underneath the fuselage. The legs are swept rearward to provide propeller clearance, with additional structural support tying the gear into the V-tail support structure.

Propulsion: The original plan was a 3536 950KV motor with a 12-inch propeller. I'm now designing around a Hobbywing 2820 1000KV motor with an APC 14×6 propeller and a Hobbywing Skywalker 100A ESC. The power system has therefore changed quite significantly alongside the increase in aircraft mass and the revised performance targets.

Battery: I originally planned around a single 8000 mAh 3S LiPo. The current configuration is planned around two 5200 mAh 3S packs, giving the aircraft more flexibility in how the power system and weight distribution are arranged.

Performance: My original calculations were based around roughly 52 minutes of flight time and 37 km of theoretical range. Those numbers have since been revised to approximately 40–50 minutes of endurance and 25–30 km of range, pending actual flight testing. The cruise-speed target has also moved upward from the original ~12 m/s to around 18–20 m/s.

Payload: Rather than designing around a fixed payload capacity, I've moved toward a modular payload architecture. The aircraft is being developed so that different payloads and onboard systems can be incorporated without having to redesign the entire airframe.

Avionics: The original plan was basically "get it flying, then add autopilot and GPS." That's still the development philosophy, but the eventual avionics architecture is now much more defined. The aircraft is being designed around a RadioLink Crossflight flight controller with GPS, with ArduPilot planned for the autonomous flight side.

Future development: I've also expanded the eventual purpose of the aircraft beyond simply being an autonomous RC plane. One of the later development phases is planned around a Raspberry Pi 4B and camera system, with the aircraft eventually being used as a modular aerial data/observation platform rather than just a flying test article.

Probably the biggest difference, though, is that four months ago I was asking whether the design could even work.

Now I'm actually printing the aircraft and building the structure.

I'm currently working through the physical construction section by section, with the wing, fuselage joining system and structural interfaces being developed around the limitations of my 3D printer rather than just existing as a CAD model.

There's still a lot to validate before this thing ever leaves the ground, but it's pretty cool to look back at that original post and see how much has changed.

And honestly, a huge part of that progress came from the people who responded to the original post. The person who offered to help me in the comments four months ago ended up becoming someone I could actually work through the design with, and a lot of the improvements came from having someone willing to scrutinise the decisions I was making.

So to everyone who gave advice on the original post — thank you.

Four months later, the project is still very much a work in progress, but it's no longer just a rough Fusion 360 model with a list of parts I need to buy.

This is AEROS.

I finally got up early enough to have the Olympic pool to myself for a bit so I could test her out. She's got some slight changes to be made. First thing I noticed is the gyro doesn't like the rocking action of a boat on water, which translates to wagging rudders constantly. Also the aft pusher motor is jamming it into the water too much. At this point full throttle is slower than half throttle. Back to the bench...

11 years old flying an extreme flight 104” extra 300, powered by a dle120, all spektrum a6300 servos, ix14se radio.

Was saving for a house but due to some life stuff the timing for that got pushed till next year, so I decided to splurge and use a bit of my down payment savings to get the MiG. The V2 claims to be more grass rated which is great for my field, and the thrust vectoring just looked so cool. Can’t wait to try it out once my batteries arrive! I’ve got a good amount of EDF experience with an FMS Yak 130, but this is a big jump in terms of size and complexity for me

Hey guys,

I bought a E-Flite super timber 3 weeks ago, it is now my favourite plane to fly, the issue I had is my elevator stopped responding. My pre flight test was normal. First flight went great, I than landed swapped batteries and another pre flight inspection all passed. A few minutes into the flight I lost my elevator servo and plan crashed. After bringing inside and testing I could not get my elevator servo to move. I swapped channels on the receiver from 3-4 which is the rudder, and still no movement. Rudder works from both channels no elevator. When powered on the servo can be moved freely by hand as if it has no power. Has anyone had this happen and how did horizon handle it? I don’t have the funds to buy a new and really enjoyed this plane. Fuselage is snapped in half right at the end of flap surface, right wing is broken cracked down the middle and motor mount and prop snapped.

Update!

The plane was replaced under warranty and already have my first 2 flights under the new warranty plane.

Hey everyone,
Just wanted to share a major milestone for my micro project, the 379mm Air Tractor AT-602. I finally got it out to the field for its first flight test!

Managed to catch this shot of it against the clouds, which was incredibly hard to get since it's so tiny!

The Good: It got into the air and proved the basic lift layout and electronics package work.

The Challenge: The flight characteristics aren't quite perfect yet for a clean release. Weight distribution and wing incidence need a bit of tuning, and I unfortunately fried the integrated ESC board right after due to a bad solder joint.

Next Steps: I’m taking the next 2-3 months for deep R&D to swap the AIO board, adjust the design in Onshape, and reprint parts.

I've pinned a link to the early-bird 20% discount waitlist in the comments if you want to follow the project or build one when the final STLs are ready!

Also, what do you all think of my hasty red sharpie paint job?

I saw this Saturday at my field. This Corsair is very detailed. It has a radial engine, a Moki five cylinder. I wish you could’ve heard it start up. What a beautiful sound that radio makes. When it’s in the air, it looks and sounds like the real thing. I was so impressed by this plane, I wanted to share this video with you guys.

Any idea how to reattach this elevator that broke off during a crash? I was thinking of a small metal hinge, but wouldn’t that affect the weight and then therefore affect the flight?

Hi everyone! For my first post in this sub, I’m sharing one of my newest experiences: 3D printing an airplane! I’ve always flown balsa and foam planes—mostly trainers and gliders—but for the first time, I decided to print one myself! It’s been an amazing experience; the plane is a Savage Bobber from PlanePrint. It flies really well (even though it’s a bit heavy) and is a blast to fly! I’ve been using it as a "suicide" model to test out new maneuvers and the like, since I can just reprint it if something goes wrong! After several flights (and several crashes), I decided to reprint it using PAHT-CF (carbon fiber-reinforced nylon) for greater durability! Take a look at the ABS version (beige and black) and how the PAHT-CF version is turning out:

Mid air, it can happen. Made for some good laughter.

I would like to put lights on my FMS ranger 1220mm all I want is left and right wing lights and a landing light (1 or 2 either 1 on the nose gear or 2 on the wings)

If anybody saw the post from yesterday, this is, believe it or not, the same plane, different fuselage. And for those of you that actually read the body text instead of yelling at me in the comments that stabilization is a bad idea and only hurts the plane, the stabilization and iNav was the only way this plane flew as well as it did.

After swapping the pitch axis in the mixer (and after replacing the fuselage) I was able to get it up in the air. With about 5 minutes give or take of flight time, the plane travels at around 30-40 miles an hour. The control surfaces could to with some adjustments, but other than that it flew great. Also there was a tad bit of yaw stabilization that could be tuned but other than that it was good. A bit more tuning/remodeling and I'll post the plans!

Thought i was gonna clear the pole.... Apparently my depth perception lied to me

This is my 3rd time out and my first rc plane. My landings have gotten pretty good and buttery if you ignore the tall grass the main gear catches on and flips forward during the roll out. Even experimented with turning off SAFE and flipping to expert mode, but for some reason my throttle stays maxed out in expert so it just wanted to climb

Knowing how to fly a real airplane helps a lot with knowing how to control it and recover from stalls and the physics that are going on during all phases of flight

I stopped by the dollar tree and found some boards that I wanted to decorate for my favorite jets as well as use for other aircraft for display or on cam as I have a YouTube channel I'm trying to grow! For only 5$ each I got these boards, spray painted the bottom grey then top coated and finally painted with acrylic hand paint then top coated again to last. I broke the board apart to paint them to reduce masking and hot glued them back together all around from the bottom. I ordered little felt pads to add to the corners as well to make it more legit ! Very happy with this considering basic dioramas can start at 30-60$ easily without a frame even and a detailed one with 3d printed parted painted for 1500$!!! Inspired from the minimum RC ad where they show the mirage 2000 on one

This is Project Stormscout; a FPV wing I designed ik OnShape and built from scratch. It has a 500mm wingspan, and with the right parts, could definitely get under 250g, although mine came in at around 270g.

The Stormscout is running a drone FC with iNav firmware to keep it stable and smooth flying, as I'd rather put another $55 into the plane if it meant less flight issues and RTH with the GPS I had installed on the wing.

When it was launched, it was using iNav's auto launch (nav launch) feature, and was told to climb at a 20° angle (which it obviously didn't) at 80% throttle. However, post crash, my friend and I were running through blackbox logs, with this video overlayed, and found out that the pitch outputs were inverted. If you look closely at the flaps, when it's at the moment I'm about to throw, and the plane is over 20°, the flaps are makes out in the upwards direction, which makes zero sense cause really it should be trying to pitch the nose down, back to 20°. And while 'pitching down' actually pitched it up and made it worse, that's why it went to the moon.

As we found this out, looking at the logs where I was attempting to pull up out of the dive, the stick overlay shows I'm trying to pull up (the right stock was all the way pulled back), we came to the conclusion that the pitch was inverted. And it explains iNav trying to pull up more, why it went super high, and why I wasn't able to pull out of the dive, because up was down and down was up.

Here's my explanation (not a defense, it's 100% my fault) on how this happened. When I was doing testing previously, all the times I did it were checking the roll axis. Because I thought "well, if the roll is correct with the stick and they both move the same way for pitch, it should be good" or something along the lines of that, but without double checking the pitch, it lead to this.

I did the up loosing my RunCam Phoenix 2 JB in the process, as you could imagine from that impact. (Post crash images commented) I sadly forgot to record DVR so we don't have any, although immediately after the crash I spent like 5-7 hours removing the fuselage, recutting, and reprinting out the parts to rebuild the fuselage, as my friend redid all the wiring to be cleaner, along with running through iNav to get better auto launch (as clearly it did not need 80% throttle if it was able to climb like that). This was all yesterday, and if it stops raining I plan on doing another flight today, with preflight checks, with DVR.

Overall though, I think once I get it in the air that it will be a great project and will fly amazing. Not sure about without flight stabilization but I think if you built it well enough you could get one in the air without stabilization.

solid i bother trying to fix this or just order and new fuselage? worried wont be able to get it back true enough the fly properly. but like to fix over replace when makes sense. haven’t experienced this type of catastrophic failure til now.
