Quad - Copters / Visuo Drone
« Last post by t0m541 on Today at 17:14:32 »
I recently bought a Visuo XS809HW quadrotor from one of the popular Chinese websites.
Been having a play with it, it seems ok for what it is and the £28 with free postage I paid for it.
I'm now mulling over doing a little bit of fettling with it to see if it can be turned into something a little more trick.

From what I have discovered by looking under the plastic is that the motor/propellor drive is certainly it's weakest link...apart from the battery life.
The motor is a tiny thing that drives the prop through a gear system, which in turn is a spindle running in a bushing that I think, after a few minutes, gets warm and causes the spindle to bind and so slows that prop, which causes instability and drift no matter how much trim you give it. thought is to get rid of the gearing system and fit brushless motors, the housings are 25mm x 10mm so lots of space to fit them.
The other upgrade is to fit an 18650 battery holder into the battery bay as the original batteries are only 900mah and last around 5 mins.
This would give much better options on mah/flight time plus increase the coptor weight a bit and so aid stability in wind, even a slight breeze and it's all over the place at the moment.
What do folks reckon ? 
Batteries / Chargers / 18650 Li-Ion flight packs?
« Last post by Reman on Today at 16:32:09 »
Just thinking aloud here.
I need some new packs for my camera hex. At the minute I'm using 5000mAh 3s packs, But I left them both charged for a week and now they're puffed like beach balls. :(

Back when I was heavily into vaping I bought a rather large quantity of genuine Samsung 25R 18650 cells (At the time they were selling for around £6 each, But buying 50 got them down to under 3 quid each!!!). Friends have "Borrowed" some, I flogged a handful, And I've used a fair few myself, But I've still got a couple dozen of these that are unused.

These cells are good for 22A continuous and up to 35A burst current. Now, By my reckoning if I used 12 of them in a 3S4P configuration I'd get 10.8v, With an 88A continuous and 140A 10 second burst amperage. The idea in my head would be to use 3x 4 cell battery sleds that use spring plate contacts (Rather than coiled spring contacts that I doubt would take the power, Or keep the cell from shifting off the contact at the other end if there was any heavy vibration). It would be heavier than the 5000mAh packs I currently use (Around 600g with the holders and wiring vs 450g for the Li-Po's), But as these cells are 2500mAh's each, that extra 150g should get me double the mAh. The hex uses about 120A flat out and around 65 to 70 while hovering, So as long as I don't get too aggressive with the left stick for long periods I think I should be OK.

The main benefits I can see with this idea is that I could swap out any suspect cells quickly/easily without scrapping the whole "Pack", And I could use stuff I've mainly already got around here. I could also pop all the cells out to re-electroficate them in my collection of NiteCore chargers (So I wouldn't have to parallel charge any of them like I would have to in a soldered together 3S4P setup).

So, It all looks like an obviously kick ar5e idea to me, But as I'm currently feeling a bit drunk from all the flu meds I'm taking I'm now wondering what I've missed........ After all, If Li-Ion was the natural future for multirotor power, Wouldn't we already be using them?
