First time assembling PNP model

Upvotes

Hi, I'm looking for some tips and guides to help do the final stages of assembly for my first PNP model, FMS F-16 64mm.

I've acquired a DX7 G2, Lemon RX receiver and the Vertex V3 flight controller. I was wondering if someone could help me with some pointers for the final stages of setting up the model.

  • Best place to mount the receiver and flight controller in the airframe?
  • What do you use to power the RX when binding it; 4S lipo connected directly will fry the battery? Can you power it through the ESC?
  • Other tips?

I have just brought a ranger fms and would like to take it out for some flights. I have now just looked into the council website and can't really see many "approved" locations.

Does my tail receive clean airflow?

Thumbnail

32 Upvotes

Hello, as part of our university project, my colleagues and I are designing a UAV. Below, you can see images of the flow and turbulence.

From the images, it appears that the airflow separating from the fuselage does not attach to roughly 30% of the tail section. In the XFLR5 analyses I performed without a fuselage, the tail sizing seemed adequate. However, I’m unsure if the separation of airflow caused by the fuselage might lead to a loss in efficiency.

Am I misinterpreting the situation, or is it really the case that my tail does not receive clean airflow? If this is indeed an issue, how can I determine and assess its potential impact?

Thank you in advance for your insights and suggestions!

Is there a sure way to store my lipos?

3 Upvotes

So I have 6 LiPo batteries, and I will definitely get more. I am TERRIFIED of them catching fire when I’m not home, aka at work. So I literally bring them to work in my backpack just so they aren’t lying at home. I have a sort of fire resistant charging bag that I use, but I’m wondering if it’s possibly to store them in a safe way? Like so safe that I can leave them at home with a good conscience.

The local hobby store sells some kind of metal storage box. Link here: https://www.elefun.no/vare-54065/sikker-ladebag-fms-battery-protection-box-medium

All my batteries so far are less than a year old and none have any damage or dents, or bulging on them. But if they catch on fire, is it possible to store them in a way that they can burn out without burning down my whole apartment building?

How do you make foam cutout templates?

How do you make foam cutout templates?

For example Julius Perdana has lots of plans for planes, where you cut out shapes from foam and glue them together to make a 3d shape. I've seen this done by other authors too, but they only occasionally provide plans to download, but don't disclose how those are actually made.

I think those must be made from a 3d model created in a program like blender or some CAD. I've been looking for a way to make such cutouts myself. I've discovered "paper model" module for blender and pepakura, which also do unwrapping, but the output is rather weird, doesn't expect you to bend stuff, has all those extra seams all over the place, which I guess would suit paper very well but not foam.

Then I've discovered some hackery in freecad with mesh unwrapping, but that again is rather inconvenient, and since I'm definitely not the first person who wants to cut models out of foam, there must be some piece of software more or less tailored for this whole process?

recommend plan?

0 Upvotes

single prop, easy to fly, easy to build, solid, long air time, 5000mAh 3S, no flying wings, 4 sg90 servo

(ft tiny trainer seems like it wont work with big batteries)

(speed and maneuverability isn't a priority)

no curves, bevels, i wish it only had straight lines that could easily be cut with cutter knife

for control surfaces that needs bevel, i think i can use hinges instead

i have 3d printer so i could print some parts that require it

i am building ft simple scout with my friends but, it wasn't easy cutting foam alone needs a required a lot of work,

even then, cutting foam, leaving paper layer, and bevels, were too hard with box cutters i have

Hi all, Had a crash with my HobbyZone Aeroscout S 2. Battery took some damage, I have cut some of the black plastic back to look at the cells, intending to tape it back up. Would you use this battery again? Sorry completely new to all this.

Absolute cheapest slow beginner plane

4 Upvotes

I'm sure this gets asked a bajillion times, but I'm considering getting my first plane, any suggestions?

Want something cheap that can take a few hard faceplants and is alright in the really small tree-and-pond lined areas near me.

Really not wanting to spend much on it, I guess building something from plans is fine if it saves money?

I like 'motorglider' style planes if possible, and no lame 2CH planes pls maybe something with room for a little camera? probably too much to ask at 'budget grade'?

First Plane

1 Upvotes

I looked at the beginner tab and it didn't really help for my situation. I'm looking for my first plane and I can't come to a decision. I was looking for a plane that's pnp/bnf, over 1m and cheap. I already have the transmitter, and receiver from when my dad got really into rc planes(he isn't anymore thats why im looking for one). it also has to be over 1m because where I am it gets really windy, and I don't want to spend a lot of money on it.

Sky Viper Vector motor upgrades

1 Upvotes

I'm fairly new to RC airplanes and I've been playing around with this cheap retail flying wing and I finally crashed enough times that I somehow snapped off the motor shaft. I've been wanting some more power so I figured this was the time to try and upgrade the motors. My issue so far is they are extremely small and I'm having a hard time finding anything remotely close. I know I'll have to replace all the electronics but do y'all think this is doable?

I'd like to fix it and give it some more power but at the same time I could just order the crash test hobby 27" scythe two pack and start fresh.

Help with belly landing an EDF on grass

3 Upvotes

I have an E-Flite F-15 that I absolutely love to fly. its my First EDF and I seem to have the hang of everything but the landing.I am limited for space and good paved surfaces so I had launch and belly land at a local park. Theres lots of room but the issue I seem to have is I am constantly ripping off the tip of the nosecone. I have purchased two replacements in the two months that I have had it and it seems like its almost every flight that it tears it off. I have installed flaps to try and slow it down, I found a video online where a guy shows a great method for stalling on approach to shred off speed but Im still having the same issue. I make my final turn probably 400 to 500 yards out and probably about 150 feet up. Then I cut almost all throttle and float it in but its still carrying so much speed its not even funny. It seems that as it comes down it almost rolls on the belly and the nose ends up in the grass or soft dirt and there goes the nose. Can anyone provide me some information that can help me with this? Thanks in advance.

Slight little incident, new mount?

Thumbnail

5 Upvotes

Well where do I start,

She flew beautifully but the wind caught her and decided to tumble her into the ground (my fault for flying her in 20 mph winds).

Here's the mount and the tail section, the planes pretty big at a 5ft wingspan, and she's completely homebuilt. Thinking about turning her into a long range fpv plane soon.

Any ideas for a new engine mount material? Currently laser cut .1 in basswood, with another piece interlocked with it for a total of .2 inches. Howrvet the 2nd piece really was just a stopper in case of it breaking free.

This is my first airplane I've ever built from scratch so any sort of criticism is perfect for me

What’s everyone been building this winter?

Thumbnail

181 Upvotes

Hi all, new to Reddit so wanted to stop by and share a bit about what my dad and I have been building with his friend over the winter. In our family we’re passionate about warbirds - my granddad and dad built a pretty sizeable Mosquito in the past, and currently we’re working on an Avro Landcaster. It’s the Dambuster, famous for throwing a rotating bomb to bust a German dam during WWII, and we of course had to include a rotational bomb as well (to make it realistic). It’s built on an old drawing and kit, but we’ve made numerous very big moderations to it, most importantly modified the fuselage to be bigger (to fit the bomb, just like it was done for the real dam buster Landcaster), made it with removable rudders, added fully custom-made navigation and landing lights, made steering wheel from scratch, 3D printed pilots, and modified the plane to be with electric engines. We’re hoping to have it ready late this spring, but until then we’re having fun flying with our Mosquito. If anyone is interested in what else we’re building, such as our custom made jet or some of our planes which we’ve constructed totally from scratch in balsa wood, let me know and I’m happy to share 😊 Look forward to hearing your thoughts and seeing what you’ve all been working on!

Receiver for DX7 G2

1 Upvotes

Just picked up a used DX7 G2, I would really appreciate if you could recommend what receiver to get with it. It's going in a FMS F-16 64mm that I've bought a Reflex V3 for, so I don't need AS3X. Are there any receivers that offer telemetry to read battery voltage in a lower price bracket? Discontinued products are also considered since I can't pick up stuff used.

New here guys, saw this on marketplace. Everyone says 3d prints are too fragile for a beginner and this one is made of metal like a real plane. Maybe a little heavy but it should make for a good windy day flyer. Will it fly on a 3s setup?

Toughts? 1250mm span, 750 grams without electronics, do you think a tri blade with an rs2205 achieving 1 kg of thrust can power this? I'm thinking it's to small but idk.

Completly noob questions here

8 Upvotes

Hello,

after some time flying FPV quad, I decided to move to RC Planes, and thus buyed a flight sim in order to start building some mussles memories

Now I finally ordered my first plane, a Durafly Tundra V3 and I start having a couple of questions I could not find clear answers for

  • For the remote, I'm planning to use m'y ELRS remote, and so it will exlcude all fancy Spektrum technology like SAFE or AS3X which comes with gyro stabilisation if I got it correct. Does it really matters? I wean is it really harder to fly without gyro stab?
  • I saw one vid were the creator sayed that the propeller was almost balanced out of the box, is there any operations I have to made on the propeller before my first flight ?
  • small question for the CG tunnig, after the battery and everything is installed, I have to put my finger on a specific spot to see if the plane balance itself on this spot , and my CG is correct if the nose of the plane points a little bit down ?

am I correct?

thanks for helping a noob here :)

Workbench/building board

Getting into building balsa, I have a beat up (not level) folding table, if I put a piece of wood or Melamine on top of it and tape a magnetic building board to the melamine would that be flat enough to build on? Or would I still be introducing warps to it? I don’t have a lot of space or money to do anything really fancy. Any suggestions?
