I'm expecting a new Transmitter and will put my present one up for sale.

Watch this space!

RCDIY:
Hello...
Here's an update on the 250mm quadcopter build.

A heads-up for people who didn't start with us on the thread but who are interested in more details, I planned a build based on an F1 FC with a 250mm frame for fast flights.
Over time, I've made changes.
1. 20a ESCs to replace the initial 30a to cut a little weight.
2. F3 Flight controller in place of F1. This will allow us expand the features of the copter later.
3. PPM receiver in place of PWM since F3 FC doesn't support PWM directly.
4. iNAV firmware instead of Betaflight to avail me GPS-based like RTH, ALTHLD and WP.

I eventually performed a test flight this afternoon and the craft flew impressively. It's easily the fastest thing I've built.

I will discuss iNAV firmware, the Omnibus F3 and their features later.

I couldn't take much pictures since I went to field alone

So, I'm doing upgrades on this build:

BlHeli ESC in place of SimonK
A new frame (260mm)
New FC (previous one damaged)
New GPS (previous one damaged)

I have achieved stability in 3D on this setup and will now aim for Waypoint missions.

Parts will be delivered by tomorrow. Will hopefully be having a test flight by Saturday

So, I ordered 2 sets of FC and ESCs. I intend using one set for remaking my previous 250 to include FPV parts.

The other set will go to my other thread where I will continue my quest for mission-capable quadcopter using iNAV.

Additional parts are:
Video Transmitter
Video receiver
LCD monitor
FPV camera

I will start work on it by tomorrow night and hopefully be flying on Saturday.

Batteries
Drones are mostly powered by lithium based batteries. (Lipo - lithium polymer, LiFe - lithium ion).
......
I will shed more light in the next post.

Lithium polymer batteries are commonly used in consumer electronics such as your smartphone, laptops, and tablets.

The two main possible alternatives to LiPo batteries are Nickel Metal Hydride (NiMH) and Nickel Cadmium (NiCd) batteries. LiPo (lithium polymer) batteries offer significant advantages over other types of batteries. The advantages that LiPo batteries offer over NiCd and NiMH batteries are:
-higher capacities which allows them to hold more power
-higher discharge rates allowing faster power transfer
-lighter and can be made in different shapes and sizes.

However, LiPo batteries also have some drawbacks. These include:

-shorter lifespan of about 300 to 400 cycles, as compared to NiMH and NiCd batteries
-more delicate and dangerous. For instance, if punctured and vents into the air, there is a possibility that this could result in a fire so extra care needs to be taken when charging, discharging, or storing LiPo batteries.

Batteries
Drones are mostly powered by lithium based batteries. (Lipo - lithium polymer, LiFe - lithium ion).
These batteries have a high power to weight ratio.

To achieve good flight time, it's imperative to choose battery type/capacity wisely.
A rule of thumb in quadcopters is to keep the weight as low as possible.
Lipos are the preferred choice for a number of reasons.

I will shed more light in the next post.

Start your journey into RC flight hobby one step at a time.
You can buy parts little by little and in few weeks/months, you'd be ready to put your craft together. Nothing beats the excitement of making a your drone get off the ground!

After damaging the GPS on my 500mm AP rig, I finally got a replacement.
I haven't flown the bird since it crashed (due to disorientation).

So I had a hover at the backyard with a 3300mah 3S battery. (No gimbal and camera)
I took about 3 minutes to acquire solid GPS lock. Quite impressive for a clone GPS module.
The battery lasted 12 minutes. I plan getting a 4S 4200mah battery later to try achieving 20 minutes like DJI drones.

The 9X is easily the most versatile and cheapest Transmitter for RC applications.
For as low as $70 you can get a radio that is upgradable and compatible with a variety of Receivers including advanced products from FrSky.
Features include 2 sticks, 3 pots, 7 switches and a 128×64 LCD screen. The 9X transmitter is also known as the Eurgle 9x, FlySky 9x, Imax 9x and Turnigy 9x is TGY9X.
The stock model with stock FW isn't much impressive but features could be enhanced through cheap and easy modifications.
1. FW upgrade
2. Module upgrade
3. Led screen installation

With these done, this sub $100 TX can compete with products that are well over $200.

Video tutorials on how to get these done are available on YouTube.

victorigwe:
open the cg, were u can install ur battery and switch.

If this is a brushless motor (I can only see two wires as opposed to three for normal brushless motors), where is the speed controller?!
How do you control throttle?

Quite a confusing design

victorigwe:
Hi Some of you will be thinking how will I buy stuff to make rc plane, or u don't have any hobby shop in your area nor money , here follow this step's and u can make a free flight autonomous airplane that can fly with out any rx tx or esc nor servo etc , am victor Igwe.

Weldone, chief.
And how will you control it without TX and RX?

PrecisionFx:
There's a huge difference between assembling n manufacturing.

Can you please tell us some of these 'huge' difference?

Rainmaker69:
@RCDIY has been holding it down right here on NL. No doubt.

Thank you, bro.

And for those who keep asking questions about 'assemble or manufacture', how are things actually made? I'll challenge you to mention one manufacturers that doesn't have to assemble or couple at some point. Only devices that are classified as simple machines can be wholly manufactured (at least mostly)
There are hardly complex machine or devices that are produced end to end these days.

On the drone...
Well done, guys! Despite tons of videos and materials available online, this project is still a daunting (and expensive) undertaking. There isn't a description of its capabilities. I see a GPS puck and assume it has navigation features.

It would be nice to see upgrades to this basic design like Planned mission capabilities and 3D obstacle avoidance.
With Planned mission, these crafts can be adapted for small to medium agricultural purposes like Pest control (Crops dusting) and farm mapping

tundeport:
How can l be part of this student to know about it,i want to learn this project pls,can anyone help please.call me or whazup me 08039705566 thanks

Will contact you.

justi4jesu:

Though you've got nothing to say, I have a question after looking at your profile.
Can you ship lipo batteries to Nigeria from US?

brendan007:
This is really cool. I think quads are the way to go. My plane is still locked up(no flying area) and I'm sure completely rusty on the controls. The system I usually use for stimulation had packed up long ago. With a quad the first problem goes away and with time the second follows suit.

That's why planes didn't interest me so much. No real space to fly as you said. Quads? I can fly even inside my sitting room.
And they're fast, the mini ones, so fast. I still got a lot to learn. And when I get better, I'll buy FPV googles and stop flying only Line Of Sight.
The stadium will make a good flying area even for planes though. Where you at?

After damaging the GPS on my 500mm AP rig, I finally got a replacement.
I haven't flown the bird since it crashed (due to disorientation).
I also haven't been so keen on fly a 500 after experiencing the speed and agility of 220/250 quadcopters.

Well, I've fixed it up while waiting for parts for the 250mm.
I also got a 220mm frame. Will start the build in march when parts (including a new Transmitter) are expected to arrive.

If you're interested in RC crafts, the basic thing is to invest in a good Transmitter/receiver. Then get good batteries.
Once these are acquired, cost of having a plane or quad is greatly reduced.

Beginners start with basic TX/RX like the Flysky series but when you get a hang on flying and starts exploring more, there arises need for more sophisticated TX.

I started with TGY9X but after suffering a 'fly-away', (I eventually found the drone, broken to pieces) I saw the need for an upgrade.

Considering the high cost of a new, TX, I opted to upgrade my TGY9X.

I'll share the details in a bit

brendan007:
Trust me, I know how you feel. Happy waiting though.

Thanks, man.
Meanwhile, I'm gonna play around with my 500mm AP rig. I've had it under the sheet since a crash that damaged the GPS.
Ordered another GPS unit but it arrived faulty. Sent for yet another and now, it's okay.
Hoping to get a better battery later to increase flight time to 15 minutes +.

Pls what is the model of the controller are u using g for ur drones and can one controller controls several drones

I use Turnigy 9X with an CH 8. But the module has history of poor performance. Also, it lacks 'Failsafe' feature.
So, I upgrade to Frsky DJT module and compatible receivers. The module fits into the Turnigy 9X. Performance has greatly improved.

I also replaced stock firmware on the TX with ER9X custom firmware. This added more features to it.

And Yes, one TX can control many drones but not at one. I have just one TX but have 4 crafts now.

Flight controllers

Naza M Lite
KK 2.1 Mini
Naze32 F3 upgrade

Frames

X525 Aluminium frame
ZMR250 Glass fibre frame

brendan007:
Oh dear! Kids are a no no when I'm working. Just have to lock myself away until I'm through. Sorry for your loss.

Yeah, true!
I needed more light so I brought the board to the sitting room.
I've ordered another. The wait is killing me though.

brendan007:
The wait sometimes feels endless. I'm eagerly waiting.

You know how it is, bro.
Yesterday, I was soldering pin to the FC. It's quite a delicate piece of work. Then, my son jumped on my back!
The soldering iron moved over the board removing tiny resistors which are impossible to manually replace.

The board is ruined. ($28)
And I'll have to wait another 3 weeks to get a replacement
