Multirotor, multicopter and quadcopter discussion - The Drone thread

The joys of having and using GPS and RTH.....

In other news, a lot of Inspires being bricked by latest firmware. Germany repair centre now have a dedicated building just for repairing Inspires.....eek

I'm at a Hampshire Chamber of Commerce event and there are two multi rotor stands (i.e. aerial photography and video) here, and they're getting loads of attention! Probably because they brought huuuge octo-copters with them, if that is a real name for them. I'm glad people are taking interest in them!

Week 6 of waiting for my motors to arrive :(

Looks good and durable, also looks pretty sealed so no dangers of it shorting out on wet grass etc.

Be interested to see your radio/video range with the video TX so close to your Rx. Also do you think you will have any issues with your ESC's possibly burning out being enclosed like that?

The vtx isn't really any closer than it was on the old ZMR250. I seem to be getting similar ranges to the old quad, the good thing is that it's not carbon fibre so it's relatively transparent to RF. I do need a slightly longer one though as I think the battery blocks the signal sometimes. The ESC's were between the bottom plates on the old ZMR, so if there was gonna be a problem, it would have manifested by now. That might change when HK finally get some UK stock of 4s batteries though!

Deffo looks like an interesting build, let us know how it flies? or post some videos, would it fly like your convensional racing 250? or are these things a little less racey?

First impressions are great. I had to drop the P quite a bit as I was getting quite bad oscillations and I still don't think it's quite dialled in yet. This might be partly as there isn't much room for any anti-vibration mounting in the frame. I'm going to look at this over the next few days as I'm on holidays this week :D

It's no slower than the ZMR and I have stacked it quite hard a couple of times today with no noticeable damage.

Just sorting a video now but my upload speed is woeful, so you might not get to see it tonight!
 
Outch flukster, hope its sorted soon

Ghandi deffo waitng for the video, i want to build something like a racer, I like the idea how of how the components are kept out the way , does escs get airflow? Do you think the frame is up to the job?

3s 1300mah 45c nanotechs, HQ5045 props, DYS BE1806 2300kv and KISS 18a ESC's.

Some airflow to ESC's, no less than the ZMR where they were buried in it's bowels.
 
P.S. I haven't quite got the hang of transcoding mobius footage for youtube yet, so the quality is a bit sucky, but you'll get the idea :)
 
Diatone Blade 150 frame turned up from China today. This thing is seriously tiny.
Going to transfer the 3100kv motors, ESC etc over from my Armatten Morphite 180. Need to cut the props down to 3" to make them work though.
With the same equipment and a bit of fiddling, it should come in under 200g with battery.
It will be running 3S so should have some punch but to be honest, the 3100kv motors are a bit heavy and slow for this frame. Really need to wait for the new 1104 3600kv motors to become available.

£1 coin for scale.
 
weyehy my replacement motors finally arrived!!

the motor cable is soldered to the control board. How do I un-solder something? i.e. is there anything in the house I can use to melt the solder, so I can at least test to see if the new motor fixes the issue

Edit- M2's soldering is very neat though!

As I will be immediately attaching more wires, should I simply stick the wire into the molten solder or do I have to remove the solder and use fresh stuff?

I ended up cutting the wires of the broken, soldered motor and binning the broken motor. I put the new motor in place, stripped back the old wiring and tied the new wiring to the old wiring (which is still soldered to the control board) and it works so at least I know I fixed the problem!

You could use the existing solder providing there is enough of it, just tin your new wire first.

I would buy a de-soldering pump for the future though, they're really cheap and worth having in this hobby.
 
I found a few 3D parts on ThingVerse which looked good. So was then looking for local 3D printers and came across 3DHubs which lets you send your files to 3D printers in your area. Anyway I thought it was pretty handy, only cost £8.70 and turns out the guy only lives 5 minutes away.

-15 degree mobius mount (will use Poron and stick it to the ZMR250)
-10 degree HS1177 FPV camera mount
- Rear bumper for LED strip
