Gaza - can you make the subject line section in the forum topic list wider? It's cutting off the subject field really short.

Had another negative encounter, it's been a few years since the last one, just an uneducated ******, going on about drones being illegal yada yada yada.    :-/
Still that didn't spoil my flying time, had an absolute blast  ~~

Chasing a slightly drunken quad

I had a fly with my flying buddy on Monday.  His KK2 quad seems to be extremely sensitive on the throttle, and made for some quite erratic looking flying.

However, it was often hilarious flying, and the most fun I';ve had in ages.  If ever you think a field is a bit boring to fly around, just get another person involved and it turns into loads of fun :)

 Ha, ha, love the near miss :cool: cool video.

Not really on topic but I have exactly the same issue with throttle control on my Multiwii based quad ... I';ve set up a curve on my TX so the halfway point on the gimbal is the hover point of the quad and between 25% and 75% only covers a very small range ie ... -100, -20,-10,0,100 but I still get that drunken flight look :)

I';ve just built a cheapo 450 clone on a kk2 which is extremely lightweight.  The FPV cam is a WDR600, and it flies on a single 2200 3s with 1047 props on 1000kv motors.  Aside from the fact it';s all a bit wonky because the cheapo motors are a bit rubbish, and are causing some wobble, it was also extremely sensitive to throttle, and would rocket off up into the sky when I';d barely touched the control.

I added expo to my throttle control which has bought it way more under control, and I can hold a very stable hover now.... but this is what you effectively did with your curve.  So another thing to potentially try are different prop sizes, I';ve got some 9" and 8" props on a slow boat from China just to give other things a go and see how they work out.

Have you calibrated your ESC';s? The old "button 1&4" trick?

Other than that, you can adjust throttle end points to soften things down a bit, I think on the KK2 and on your Tx too.

Growing old is mandatory...Growing up is optional

Yep ESCs calibrated.  I tend to think the sensitivity comes from the combo of light weight/high(ish) KV motors/props.  Expo works fine for me, I prefer to have the full range of the throttle in case I want to do an impression of a rocket :)

yeah works fine on the laptop.  Great vid, I need to get a flying buddy!

Hmmm ... I';m running multiwii on mine but my problem also seemed to be quite a lot of altitude variance even when the throttle wasn';t moving and I was just trying to hover.

I did some googling and came up with a few good hits ... basically vibration kills things ... I dropped the LPF from 98Hz to 42Hz and it is MUCH better at holding a hover with the throttle not moving.
Perversely it now has a lot more kick and I';m going to need to revisit my curve as the hover point has moved and the throttle is now hyper sensitive again.

looked like you some proper fpv quad fun!  What distance is that down to the tree, where you were turning back.?

Neil is doing good on the KK.

Not too far, 350m.  We stand on the line between the two fields so we can fly the full fields in front and below us (and have LOS around a dogleft left in the forward field).  Neil was on a Boscam 200mw, he was getting some drop outs at the end of the field when very low, the Immersion 600mw I was using had no issues though

Gav

Did you sell him the Boscam200mw you had off me LOL

He definately got further than 10m  :laugh:

I think we';re both committed to just going Immersion in the future, to get to that field involved backpacks, jumping over a steam and carrying gear.  You just don';t want to be dragging along a ground station and external VRX as well as everything else.
