Sure. But basically, all the subjects are getting cut off.

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

Just had a thought, even with all the crashing I've done, I haven't bought any replacement props in over a year ~~

PK 450 not behaving itself

Hi
I';ve never been able to get this quad to go straight up.
I can hover it but always need a lot of stick input which doesn';t seem right. I';ve levelled it with 15 sec left rudder and also through mission planner but nothing seems to work.
It also seems very twitchy with the slightest stick input.
Any help gratefully received
Regards
Roy

Hi Roy whats a PK450 you got any pictures, do you use expo on your Tx  :popcorn:

Royston

Sorry Gaza
Peter King!!
Will check tx settings later and post.
DX7s file sent from Peter. Only upgraded firmware and not changed any settings.
Regards
Roy

Royston

Hi Gaza

Throttle/Aileron & Elevator set to 120%
Gear  40% & 100%
No expo on any.

Regards
Roy

Has it always been like this? I have "pk450" and it is do easy to control. I can hover a couple of inches off the ground in the house and throttle control is so predictable.
Might be an idea to contact PK and see if he has any ideas. I have always got very quick replies from him about my Wuad, it us generally me doing something stupid!

Cheers Allan
Yes its always been the same.
Are your settings the same??
I';ll try emailing Peter though.

Mine is exactly the same, no problems with it at all - not upgraded the firmware though; as I was happy with it why fix something that isn';t broken?
I think..........I think I am........therefore I am.............I think!

Yes, looks like my setting are the same on my Dx7s although the screen shows gear as 100% 40%
I used the file from Peter for my TX. My 450 came with 291.r6 firmware and I had an email from Peter last week with advice to upgrade to 291.r300 because people were reporting flight controllers disarming mid-flight on the old firmware. There are lots of threads on this on other forums ( fora?)
I upgraded the firmware and params, downloaded from links on Peters Youtube vids and it flies great.

I wonder if it might help to upgrade your firmware and params? Its easy to do, only takes a few minutes.

Allan

Forgot to say, my quad doesn';t take off till the throttle is in mid position, but always stays very level. When you open up Mission Planner, with quad connected, it shows the current flight mode which should default to "stabilise" ( shown above GPS status in the Flight Data tab. )

Royston

Bummer!!!
I have upgraded to fail safe firmware but I think there';s another one since.
Just had a reply from Peter who said try calibrating ECS'; but all 4 motors start up together so can';t see that being an issue.
Have emailed him again and see if any other suggestion??
