one Girl's Rave ENV Build or "pink my Rave"

[ChrisB]

As far as i am aware the you as the pilot have authority over cyclic not the controller,the controller wont suddenly decide to throw full cyclic unless there is something wrong with it,vibes maybe or you asked for it.(well it shouldnt anyway)

Moving the cyclic a bit or a lot gives the controller an idea of the rotational rate you are asking for if you move it a bit and the model is on the ground it simply does not keep increasing the swash tilt until the model moves,try it and see on the bench.

im sorry i totally disagree with what you said i have been flying for 8 months (not very long i know) and converted most of my helis to flybarless and i can honestly say its not anywere near as bad as you have said yes they do move a tiny bit but dont fall over on the ground as yours did, flybarless is no way as scarey as you have made it out to be, personaly i think your accident was due to 1 of 2 things poorly setup controller~mechanics or faulty controller none of my flybarless helis have ever fallen over on the skids !
put it back on and try again you will like it

Hi I agree!!!
I have stressed this is my build blog and as such my oppinion right or wrong and I do want you input & help, no matter what your experience.

I have been over the crash several (million ) times in my head and It wasn't bumped down it had landed and been on the ground for several moments and was spooling down , the incident only occured as the collective was lowered below 1/2 stick .odd i know it didn't just slowly topple over it rolled so fast to be honest I don't even know if I reacted.

a couple of thoughts the total g has a feature to stop tip overs on spool up & down where buy the gyros dont work below 1/2 stick is there any way I could have had this reversed ????!!!!

secondly
why did the boom bobb up and down almost like the headspeed was too low but not quite as fast ?

I haven't given up just put it on hold due to wanting to fly not set up and money !!!

Hugs all X

[heliward0]

not using a dx8 are you???

My FB ENV seems to need a high headspeed otherwise it shakes a little, which goes as the headspeed increases.
The boom bobbing up and down could be related to the elevator bobble that I've seen people on Allmyrc and Helifreak complain about. Apparently this will be fixed in the next update.
What were your flight control gains at? If it felt soft then the gains could be too low and in a way that could have contributed to the tipping over on the ground.
I'm still going to go with the FBL conversion and give the TotalG a shot, I just hope it's not a steep and expensive learning curve

[rachel]

No its a JR DSX9 Its ok with rexy (my 700)

But thanks for a sugestion I only am sad because I don't have to money or the guts to carry on with flybarless at the moment.

I read a comment some where that said "Flybarless is almost as good as my flybared model" humm Isn't it supposed to be better ???

I haven't given up totally as my heli buddy is fitting it to his 500 so watch this space

at least I will be able to post some pic's of the nice flybared head.

Keep up with the ideas folks it all helps.

's X Rachel

the bobbing / wobbling normally happens when there is too much gain on the cyclic servos much the same as too my much gail on the tail causes wag but for cyclic! do you have any idea what the gain percentages were on the cyclic ? 1800 is not really a too lower HS to induce this .
really is sounding like your gains were too high (sensitive) if i up the gains on the 3g system the heli wobbles/shakes like a jelly when you input cyclic movements and do flips etc
i think people who have not used flybarless b4 are in the thinking that high gains= mega stability but its not the case it the oppisite it causes mega unstability and the model sufferes very nervous take offs and landings (as you had) and shaking/wobbling in flight (if it gets that far) from memory on my 700n 3g the total gain on the AIL/ELE is 35%-40% and its mega locked in must say as much as folk knock the align 3g system its mega easy to setup its more of a plug and play system over the totalG v-bar etc

With the TotalG, and other controllers I guess, the controller has command of the cyclic and it does nothing with collective inputs, it just passes them through. To me this makes sense because a flybar has / is effected by cyclic inputs but is not effected by collective inputs, and a FBL system is replicating what the flybar would do.

[ChrisB]

Good luck with the further testing with it,i think no matter how much positive feedback you get on a product online you still need to personally gain trust in that product when fitted to your model otherwise it ruins the joy of flying as you are worrying if something bads about to happen with it,at least i always do..

To add i flew a T Rex 700N the other day with the Total G,first time i have tried one and i think it flew really well,it appears to me to be a very good system and it felt great.

Hi the gain was 48% which is factory default .

I find it very sad that I cant carry on testing but hopefully I can borrow my friends 500 and we will continue.

I still stand by what I said "It's not plug & play"
I want to fly and improve my flying not chase setup issues , so for the moment its back to flybared for me.

But here is one to throw into the mix ,.... surley with my experience / abbilities I should have been able to take off hover & land without tipping over.
There must be a fault !!!! (remember a woman is Never wrong )

i too have seen/heard this comment too.??
but i fly a 600le with beastx and its one hell of a machine i must say!!!
and it really does fly better than the flybared model

Thanks for that so there IS hope

[Brian Gifford]

Sorry to hear about your problems with your maiden, Rachel. I understand your reluctance to risk another crash. I' ve recently gone fbl, and am delighted with the result (beastx) Perhaps you should try fbl on a cheaper helicopter? Good luck with the repairs, and the next flight.

[heliward0]

sell the total-g then you have the funds to buy a beastx and repair you heli !!

[Paulice]

Hey Rachel,
Sorry to hear of your problems, It is nerve racking a new heli and a new flybarless system all at the same time, I can't say about the total G but with v-bar, i've only once had a on ground tip, that was fully my fault, and i touched the blade tips on the ground, for a split second, I did nudge the cyclic stick when fully spooled up .

The up down nodding you mentioned could also to do with head speed, ? when i drop the Srimok down to 1050 rpm it wobbles but still sits hovering with very small corrections.

As for why yours tipped over, not sure, but you also have a ground resonance, it applies more to bigger scale heli's 2.5 mtr + that if they are sitting on the ground spooled up and have -pitch they can start to violently shake, and would if nothing done shake to bits, you might have on yours during spool-down and 0 pitch, a vibe that caused the sensors to react???

Well don't give up hope.
At least your canopy is still intact
