Keil compilation instructions for silverware:

Compiling a firmware with custom options is done using the software program Keil, on windows. This currently is the correct procedure for Bwhoop b03, E011 and also H8 mini with blue board. Use the right code for the board / quad please, they do not work correctly otherwise.

Software installation:

1) Install Keil MDK from http://www2.keil.com/mdk5

2) Install STM32F030 cpu support pack using the pack installer in Keil uVision. You may also skip this. Keil uVision will ask to install the pack when the project is open, if not installed. Choose "install", and wait for installation to complete (download). This will take some time.

Compilation process:

Assuming the installation process was performed correctly, we will now use Keil to compile a "binary", which is the file containing the firmware of the quadcopter.

1) download the project files from https://github.com/silver13/BoldClash-BWHOOP-B-03
Unzip to a folder of your choice.

2) open project file "/Silverware/silverware.uvprojx" or similar in the Keil uVision program. This can be done by double-clicking on the file for example.
Keil uVision may ask to install device support if not present, click "install", and wait for completion, which may take some time as it is downloaded.

3) Change the settings to your preference, generally using config.h and pid.c for acro pids.

3) compile the project and make sure there are zero errors reported in the lower part of the window. Use either the "build" toolbar icon, menu "project/build target" or "F7" hotkey. Keil will also save changes to files at his point.

4) Open the folder "/Silverware/Objects" ( name may change slightly) and find file "bwhoop.hex". This is the firmware file, to be flashed to the quadcopter using the "st-link utility" program.

Took a five year break from the hobby but I'm starting back up with a purchase of a Syma X5C-1 for now.

Charged up my old Walkera Ladybird and the Devo 10 TX and tried to fly. I'm horrible. Still having a hard time with that damn thing like I always have, the thing is so squirrely.

It's interesting to see the advances in the hobby in the last 5-6 years.

I'm hoping the X5C is a little easier to fly. Looking forward to seeing some of the camera footage as years ago no inexpensive quads even had cameras, now it seems you can't find one without!

Hello!
I am completely new to everything on this website and related to this website!
However, I have a question regarding quadcopters and payloads.

Is there a way (formula, equation, ratio) to demonstrate the relationship between the rotor blade length, RPM, and motor power?
I need to theoretically hover about 10 pounds 3 inches off of the ground using quadcopters, however, I know absolutely nothing about them nor how to set this up.

Any input is appreciated,

Thank you.

Servo cover making (2 min 7 sec)

Posted by BernardW | Yesterday @ 07:18 PM | 426 Views
I'd like to add a Raspberry Pi and some sort of servo etc. controller board to my RCM Trainer 60, and add autopilot software such as Paparazzi or OpenPilot, not to use commercially yet but to start getting some knowledge and experience of fixed wing UAV's. Eventually I would like to get into this commercially using my own designed and built aerial platforms, in a much larger size and carrying more instruments, for geological surveys for mining, aerial photog. for farming, forestry or anywhere you need to cover a longer range and get aerial photos or other data. I'm extremely interested in this and have many ideas.

If anyone has done this, as far as adding autopilot and other robotic control software etc. please let me know, I'd love to discuss this and get your advice, and I'll post everything I manage to get working. I know there are UAV areas on RCG so I will definitely check them out next.

Pretty much ready for maiden flight!

One of my motors needs to be replaced, but should still work for a couple sessions i hope.

Somewhat tricky build due to you need to use some specific parts to work with available space.

I decided i wanted this frame so i could easily mount my runcam2 hd cam. BUT when the runcam2 is mounted, it does not appear that im gonna be able to run 5inch props which i kind of a bummer... :/ Without a runcam2 on the back it will easily run 5inch props. I will be running Q4040 dalprops on my racerstar 2205 2300kv motors. they seemed to be nice on my 195 kim setup but i didnt use a runcam on that build...

I ended up getting new foxeer arrow ccd 2.5mm lens. It has voltage osd which is nice. I was gonna try a much cheaper cmos cam kinda like a fatshark cmos cam, but the connector was at the bottom and there is hardware right where the connector is which would be snapped off on a crash most likely... the foxeer connector is at the top.

The TBS Unify vtx i used has U.FL connector which is good bc less chance of vtx damage if/when antenna lead gets yanked (it will pop off instead of rip off). I used a 10mm lead with 90degree sma connector i believe. the flat backside of the TBS VTX i have allow it to fit in the mix pretty well. I also picked up a dipole antenna i can connect via UFL connector if i decide to lighten my load a bit.

I was gonn

working great! i really can't wait to upload flight footage!
only thing is that there is 18 km/h wind here
anyways, enjoy

One more Model Expo visited. Brought three planes to our club stand: 3D printed Spitfire, Extreme Flight 48" Yak 54 EXP and indoor Extra. I also flew dozen of demo flights with the Extra in the indoor flight arena.

I was very happy with our club stand, we had plenty of different kind of planes for display there. Also simulator was available for visitors / interested people to test. The fair itself is getting smaller and smaller. I guess it's just too expensive for hobby stores to attend, which is a real pity. Raku actually was also the only flying club dedicated mostly to aeroplanes attending.

More pics are available here for those interested...

Here is a pic of my Saito FA-72 Exhaust Manifold.
This manifold thread size is suppossedly 12x1mm. Threaded on both ends.

It looks a bit too short to work as a 'Pipe' like on a Saito FA-45 MKII
or Enya 46-4C.

I think a 2-inch extension would work, with tip rounded inwards a bit to aid pressurization.

I ordered a sailplane holder from Greece recently. It arrived this week and I am glad I got it. I am always nervous leaving my sailplane on the grass, loose dogs and small kids. The other day I watched a small kid jump over my sailplane because it was too much effort for him to go around it This will give me some peace of mind. It's well made and sealed with two coats of sanding sealer. The product is priced reasonably at $35 bucks. The problem is shipping from Greece to the USA was $38.

I purchased on this thread:

My first attempt at flying through things on FPV with a Rise Vusion. I only have about a half hour of total FPV time at this point, and am still trying not to fly the multirotor like it's an airplane. This is going to take some time and practice to separate that problem. I think I did fairly well though.
