600efl pro advice please

[SaneAdam]

Hi all. Just wondering if anyone could offer any advice on the 600efl pro. I have to say I'm finding it a bit cumbersome in the air in general. Especially while doing flips. Im noticing that aileron is creeping into to the move somehow... or so it would appear anyway. Its not pilot error (cyclic wise anyway) as my flips and rolls with my 500 are very precise and smooth. As it goes over it looks like its developing a shudder and almost seems to bog down. Could this be down to collective management? Don't seem to have a problem when doing em with my 500 or 450. But they both have beasts while the 600 has the 3gx. It seems to twist slightly during flips. Rolls are ok. Could it be related to the elevator gain pots? Would it help to mess with the 3gx settings through the pc software? If so does anyone have any recommended settings? I have not done the 3gx updates yet either. I find all that stuff a bit of a minefield really and don't want to mess things up as appose to make things better. Would be interested to know if anyone else is experiencing similar issues. Its kinda ruining the enjoyment of this help at the moment for me. Could it also be related to the tail? Would the updated tail setup improve these issues? Im using 4400 lips and I'm wondering if the weight is also contributing to the cumbersome feel of the help. Would 3300's make it feel better?

I realise there are a lot of questions there. Thankyou in advance to anyone that takes the time to read and make sense of it all

Any help thoughts or advice are massively appreciated

Thanks people

Sorry.... my bloody predictive text changes heli to help much to my annoyance!!!!! Also changes lipo's to lips!!!!!!!!

Adam what headspeed are you using, I doubt your bogging the head although you may be losing tail authority if you've cranked the hs down from stock and 100%

[ChrisB]

As above what is your headspeed approx or failing that i assume its all stock,whats your throttle curve setting.

[SaneAdam]

To be honest I'm not sure what the head speed is. Not messed with that (I don't think) My tech friend does all my setups for me as i have adhd and bipolar so i struggle to be able to do a lot of the technical aspects without either being distracted by shiny things or getting very angry at not being able to understand things properly ... other than flying that is. I think the pitch is set up to +-10.... lol... i think What else would affect the head speed? Sorry for my lack of technical knowledge

Thanks for your patience. I realise it would help if i knew more about these things.

[SaneAdam]

throttle curve in idle up is 100,90,80,90,100

[Zeeflyboy]

Cumbersome does not describe this heli....

So, given that, we must assume it is a setup issue!

For interaction, my first port of call would be to check the 3GX - is it mounted absolutely strait? If it is off line then that will cause unwanted interaction.

For bogging, there is no way you should be bogging this head with flips. I assume you are running in fixed end points but you really need to as your friend how it is set up. If you know how, take a look at your throttle curves and tell us what you have set.

Edit - okay you posted curves... That should not be bogging (especially if pitch is only 10 degrees.... Bit low that btw, 12 is a good starting point. You are running this on 12S lipos correct? Might be a silly question but I did read about one guy trying to fly it on 6S...

[ChrisB]

It could be a 3gx setting issue but i am wondering why you would describe this heli as cumbersome as it should be pretty lively.

The only thing i can assume is you are running too low a headpseed for this model,i have had two of these now,the first one blew itself to pieces in the air but before that i found trying to run a headspeed anything under 2200rpm resulted in it feeling very loose in flight,i wouldnt go as far as saying the cyclic was bad(ran V bar though) but it felt boggy and most importantly the tail was very loose.

Running it above 2400rpm was a different story and it flew very well.

It would be helpful if we knew what speed you are running yours at as a starting point at least.

[SaneAdam]

Running 12 s yes. 2 4400's. Everything looks as it should with the mounting of the 3gx. He has built and set up all my other heli's and they are all flawless other than the 600. So i wouldn't think he has done anything wrong build and setup wise.

[SaneAdam]

Ok. so how do i find out what head speed it is running? Once again thanks for your help guys

[Zeeflyboy]

Do you have a smartphone?

[ChrisB]

To add to what Zeeflyboy said,agreed at those curves you should be spinning those blades fast enough so assuming you are running 12s i am a but stumped.

10 Degrees on this model is nothing,i dont think it would be possible to bog it if you tried every trick in the book.

[ChrisB]

Do you have a smartphone?

He might do but theres no point asking that?

[Zeeflyboy]

Just had a thought... Are you 10000000% certain that the batteries are wired up properly in series? If he had accidentally wired them up in parallel you'd only be getting one big 6S pack despite having two packs plugged in.

Chris - there are headspeed measuring apps for iPhone and android! They work pretty well actually, quite impressive.

I don't have a smart phone I'm afraid.... just an old nokia brick
