Vbar 700E maiden didnt go well

[Tim Procter]

Hi the elev is on the outer hole the previous owner told me it worked well in that config.

Jason, the ex owner is talking out of his rear.

All three cyclic arms must be the same config "ie" distance from the main shaft, The aileron arms are on the inner holes, your elevator A arm is on the outer hole.

All three must match mate.

PS: Posted your stuff off today.

Thank you Tim, Thinking about it the way it flew it was like a mismatch ie it would pitch up then level its self which would make sense as the vbar leveled its self.

It's hard to see in picture 6, but I think you've got the bell cranks in the inner hole, and the elevator arm in the outer hole.
Please check...

I use a little bit shorter servo arms and longer blade grips (assuming yours are Align), but it shouldn't be a total mess.
The DS610 are quite power hungry. 8 amps per servo should be sufficient check if this combination works for anybody else.

edit here's a picture from my own 700. The elevator arm uses the inner hole.

8 amps per servo may sound absurd, but the helitron regulator I use is designed for 50 amps peak for a reason...

Hey.

Yeah, I just spotted this myself looking at the pictures. This will cause a problem in that the elevator servo travel will need to be reduced to compensate for the ailron servos/bell cranks moving a shorter distance.

The FP 8amp reg should be more than enough, Duncan Osbourne use's them on his 700E's. These have a variable output from memory, what do you have it set to?

I've downloaded your Vbar settings file and am going to have a look at it. My model is next to me to rip mine off, which I think is working well and I'll post it with screen grabs of the various banks.

Hi Ian thanks I was told the heli had been used in the comp and not touched since !!! but thinking about it it cant work. You can read and save the settings into a vbar file and post that, It was showing approx 6v on the vbar screen.Thanks Jason

Hi Jason.

Hmmm, as you and others have said knowing that all 3 servo's need to move at the same speed & distance tells us that the elevator bell crank "A" arm position will effect how the swashplate moves. While it can be made dead level at mid-stick, at the extreme's or travel and during it's travel either side of centre, it will not move at the correct ratio to match the other 2 servos.

Anyway, it's easily sorted and a quick run through of the Vbar setup will have it all set nicely once again. I'd even go so far as to say wipe your model memory and start from a clean slate, like the Align FBL unit's this will probably make for a good setup once completed.

Attached is my settings file and screen grabs of the various banks, I forgot the log file but will go get it now.
The 5 volts shown on my screen grabs is misleading, but it's at this voltage as the ElyQ regulator sends 5 volts back to the receiver. My servos (DS610's) are running on 6 volts on this model.

Hi How do find the diffrent banks fly in real terms ? Do you use any expo etc in the radio or just the set up in the vbar Cheers Jason

Hi Jason.

Well each bank can be setup individually to one another, once turned on I found that each bank presented a new default set of parameters which can be tuned to how you like them and can then be assigned to a flight mode.
For me, as I am used to flying and switching between different flight modes depending on the type of flying I am doing at the time, upgrading to PRO allowed me to achieve the same setup as I would normally have done using dual rates/exponential switched automatically with my flight modes.

As can be seen in the screen grabs I run a softer Normal mode setup, gradually getting more agile as I switch up through Idle Up1 and and a little more rock & roll in Idle Up2. This is combined with increasing head speeds controlled by the ICE2.

I do use expo in my transmitter as well, with Aileron and Elevator set to 30% and rudder at 25%.
I've also not used the optimisers, just fitted the Vabr, set rough parameters, then using the cheap BT modules and my Android phone/tablet flown and tuned settings between flights without returning to the pits, except when I need to change battery.

I have watched the vid on bank switching and set the tail diifrently in the diffrent banks but never got chance to try it. Can you switch in flight without any glitches ?

Hi Jason.

Yes, you can mate. As an example I start off in normal mode, taking off into a hover to check the model feels ok, before switching into Idle Up1 mostly for the tamer 3D moves. I then switch into Idle Up2 for the aggressive tic-toc style manouvers for instance.
I've not had problems swhitching banks in flight, the only thing to double check is that you've set each bank up! As if you've missed one and switched into it you might have an interesting time controlling either a very numb or lively chopper ;-)

BTW, when I loaded your banks, it showed the default expo on swash and tail.
If you don't want it, set to 0. Do not use expo on Tx and V-bar at the same time, it's most likely not what you want.

You don't really need bank switching. The V-bar setup is pretty robust.
Get your heli sorted out first. Then enjoy flying for a while. Then worry about bank switching

Hi All sorted the A arm out and stuck 3 x differentsetting in the bank switching. All the bad habits have gone its completely differentto fly. I had to get the agility to about 110 to make it lively enough for me .The only difference in this 700E and my beast x one is the head dampers thisone has green ones, I may change them for the black ones as i am still no happywith the way it goes in and out of moves its very switch like and I just don'tfeel relaxed flying it. I need to have a mess with the setting again if thedampers don't smooth it out. The plank flyers at the club cannot believe I haveto take a laptop with me to adjust a model but impressed every one with flight analysis and the spectrum analyzer .

The Lime Green KBDD ones I had were quality. If you have the same, that wont be the problem.

Hey buddy.

Brilliant news, glad you're now sorted and flying.

I think the flight condition slider can effect how the model feels getting into and out of a manouver, as well as the flybar feel slider. I've not had to play with mine much as it just works great.

Pop a bluetooth module on the vbar and adjust settings with your Android mobile phone, that will confuse the plankers evenmore ;-)

Yes they are lime ish green really hard like two lumps of plastic. I may be used to the way the beast flies ?

[jasoncook]

Thanks Ian,Sacko, Once i got the rates up it would hold position throught fast on spot rolls and flips even with a strong wind. Tight funnels seemed a lot easier than with the beast,But big gentle moves felt twitchy ?? I think i need to go down on my own a just mess with the setting to find out how they effect the flying Cheers Jason
