You can look into parallel charging, it comes with some pretty hefty caveats which you really should understand before attempting it but is safe if you follow the rules. HK has parallel boards for sale, though make sure your charger/PSU is up to scratch on the kind of current this will draw. Charging 4x1300mah batteries at 1c will be draw ~5.2A

My charger does 5A, but I think I would prefer to get 2 chargers and charge at 2 or 3C. Looking at parallel charging there does seem to be a lot to check. Needing the cells close in state means I might end up discharging a load individually before charging, which eats into the time saved.

Is there a setting on the KK board that stops the twitching when self level is enabled? It's fine when it's turned off but when on it seems to be skipping on one motor. The gyro sticks a lot too at a weird angle.

Edit, after looking at a vid i'm pretty sure it only does it when it's in a wind. Seems like it's over compensating.

The KK auto leveling can be tuned. Its what I need to do as like you with it turned off it's smooth but with it on it's jitter bug tastic.
 
@ d_brennan

Ok here are my settings

Steveis Firmware V1.18S1 Pro

Roll (aileron)
P Gain 65 P Limit 100
L Gain 30 L limit 20

Pitch (elevator)
P Gain 65 P Limit 100
L Gain 30 L limit 20

Yaw (Rudder)
P Gain 65 P Limit 20
L Gain 50 L Limit 10

Stick Scaling:
Roll 30 Pitch 30 Yaw 45 Throttle 90

Self Level
P Gain 75 P limit 20

Anything look obviously off? I will look into making some changes but if there's anything worth changing right away I will give it a go.
 
To be honest, general flying I find actually easier with the self level off. You find yourself just setting the angle of the quad and it holds it there and you zoom off, no holding directions :) Only flip the self level on if I lose track of the quad and want to make sure it's atleast level!
 
I think I will keep it on for take off, as my first attempt at taking off with leveling off met with a collision with the washing line :)
 
Should just go straight up if you don't touch the right stick and give it some throttle!
If you take off slowly it tends to get blown around by it's own turbulence on the ground. Better to just give it some beans :)

I'd just dial P down, say 10 points, give it a bit of a fly. If its better, knock 5 off and repeat, then 2 (pitch/roll are linked). Tbh, I've spent hours and hours messing about with kk pids and I'm never happy with it completely. Tune it out one day, the next day its a bit windy and its not stable :/ Naze32 is calling you :p

Will give that a go

I know I really want to get one but at the moment I have already spent twice as much as I'd hoped.

Is it really that much better? Also can you connect a battery alarm or a buzzer for a lost mode?
 
this is strange I had quite opposite experience with the KK, PIDs didn't seem to do much difference, stick scaling did. Otherwise it was fine auto level or otherwise.
 
Here's a video I did today, 2 short flights of around 7 minutes with 2 minutes chopped out....no not any crashes. Furthest I got going by google maps is about 900m till I got beeps from the TX, depending where abouts I was it would go beep around 750m. Video was clear all the way so I need to increase my TX/RX range somehow.

I got a Naze32 mini from abusemark for about £11 delivered just out of curiosity, didn't expect it to be great. All I did was (after soldering the pins of course) connect it up to baseflight, run the calibration and set a couple of modes using the CLI (motor start off, CPPM mode etc) and whacked it on. It flew great out of the box, the only change I made before it died was to increase the yaw rate... But I landed my FPV250 upside down and one of the sets of header pins got bent 30 degrees or so. When bending it back I pulled the pads off the PCB traces and she was no more :(

Good video, braver than me going over the water.

What vtx you using? That's really good going.

I'm using Fatshark 250mw with the Immersion spiro antennas and lucky to get 450m before I get major interference. I think this is might have something to do with my video antenna and the 15cm extension being on top of the radio RX, I need to test it over the weekend.
 
I'm using the 600mw ImmersionRC with spironets. I'm getting interference when I really put on the power, My VTX gets it's power from the battery using a filter that connects to the balance lead. It's sat right next to an ESC so I'm copper foiling everything.

Ah makes sense then, yeah I'm using a filter too with the power coming of the balance plug.

Got any photo's? Be interested to see the copper foiling.

Total of 13.2 amps at half throttle, but what is it at full throttle? Imagine you've got 10-12A escs on a 250 build so you're potentially pulling 40A+ based on that? I'd imagine a 35C battery would make things a little better if you are lacking punch?
Click to expand...

About 28-29 Amps at 100% but the motors are rarely near that. I've ordered some 35c nanotechs now and will see how that goes.

Next is 4s and 6030 props :)
 
Thinking about just biting the bullet and getting a naze but not sure whether to go for full or acro.

I won't be using RTH or GPS hold, is there any other reason to go for the full over the acro?

Also would I need the "breakout cable" or can I just use the same cables I used with the KK and RX?
