Guys i have just converted my Synergy to flybarless

This is a brand new machine

Im useing Vstabi version 3.10, its an old version (i had a spare Vstabi sitting around)

I will update it to 4.0 soon

Im wondering if anyone has done a conversion with Vstabi and if there was anything that they needed to change or set in particular to work with this machine being Nitro.
I have set the sensor to IC setting already

Thanks Dale

Always wondered what that setting was for on the sensor lol. I thought there were 2 different types of sensors.
Looking forward to playing with this next weekend!!

Synergy
Jared we can give it a beating next weekend if we get it dialed in quickly !

I have received a PM from a run ryder member who said he was talking to Tood Bennet last weekend and he had a good working program and some information relating to linkage lengths etc etc

So i have sent Todd a PM for any help.....

lets see if we can get a working program, saves us time !

Chat soon

You have to run the ball on the servo arms at 10mm not the standard 13-14mm. Otherwise the swash will bind with cyclic input. The servo supports will need to be raised so the balls can clear. At 10mm swash interaction at full +- collective will be high but there is nothing you can do about it. The good news is the vbar will correct for all swash interaction in the air.

What rotor head are you going to use?

Thanks for your reply

I am useing the std synergy head with SE grips and some extensions to space the ball centre to centre of 62mm just like my logo 600 Vbar

i have put a grub screw in the std washout and modified the Hyper washout arms.
all works well on the bench

although i did think the balls on teh arms might be too far out from the servo centre as on the Vstabi menu i have to bring the collective amount back to 60 and thats 12 deg either way !

I am still waiting on Todd bennet to get back to me on his thoughts

do you have any other info you may be able to relay ?

thanks in advance

Dale

Yes not only is the collective common too low but the vbar will over drive the swash on the bench and when flying. The machine will hover ok but if you try to fly it fast it will either get out of control or boom strike and explode! 10mm at the arms is a must on the N9 due to the bellcrank mechanical advantage.

Because of the increased loads on the servos make sure you are confident the servo arms are thick enough, the link ball and nut on the servo arms are secured with red loctite or use 3mm link balls and metal servo arms, and the rx battery and regulator can deliver a good about of current per flight. For example my 600N with futaba 9255s on cyclic used 550 to 600mah per flight with vbar 3.6.16. Your older vbar won't draw this much current but it's safer to run a good regulator and larger battery pack. Another reason to upgrade to vbar 4.0 on the newer sensor is the reduced current draw.
do you have any other info you may be able to relay?
I tried to get Matt's N9 vbar setup file last summer but by the time I asked he stopped flying the vbar. I would load either the Logo 600 or Trex 600N preset and change the swashplate basic setup and tail servo settings to match the N9.

As usual some settings like Collective and Cyclic Rate are set based on how you want the heli to fly. Start with the preset and adjust as you like but I would lower all the deadbands a lot.

100 paddle weight is good and will prevent the heli from pitching up in high speed flight.

I liked Extended mode as I preferred lower cyclic gain.

Run stiff dampening in the head, but not so much that the bearings are dragging when the spindle bolts are fully tight.

In the tx I ran 25% expo on cyclic and 50% on the tail, so it felt like my 611.

Thanks all I can think of for now.

Bart,

Where's your carbon frames? Nice wiring job, I wish I had the patience for that.

Those are the carbon frames. Note the radio tray and the extended portion at the lower canopy mounts.

Thanks dude.I shelved the Quick UK carbon frame kit for the Fueled by Hate carbon frame set.Gotta have the latest and greatest ya know

baddraptors very handy FBH build thread

I made a few changes with the bellcranks,linkages and sensor mounting.
I'll let you guys know how it turns out.

Looks like she balances nicely the way it's set up with the 4 cell out front.I may make some changes there when it's all said and done.

Are most of you guys running Li-Ion or Li-Po for a receiver battery?

I'm running all Arizonas with lith ion rigs.As it sits,the one in there is a 4 cell 5000.
I'd like to go to an Outrage lipo as long as it can balance all up with half tank.

Bart,

keep us informed of the FBL process. I am getting ready to go FBL since my engine is broken in. Your a step ahead of me now..

I think most of us are LiPos, at least I am..

Chuckie

great thanks

I have a set of the HD JR arms for my 8717,s.
Im running them on a 5000MAH lipo straight in, with a spectrum step down for the tail servo (BLS251)

I will go home and do a new setup with the balls at 10mm and space the servo support braces up a bit so they can clear the balls

I have my sensor mounted at the rear sensor mount ontop of Zeal ?

any other tips ?

Thanks Dale

Your setup will draw a lot of power. Definitely check the current draw by fully recharging and noting the capacity added back after one or two flights. I'm interested in hearing how your 8717s fly in the N9 with vbar. My N9 FBL conversion will use the same servos but at 6v regulated.
I have my sensor mounted at the rear sensor mount ontop of Zeal?
If you note the FBH frames and other N9 FBL conversions the gyro sensor mount has been moved up front, connected to the frames. I'm not saying the rear mount won't work but most feel it's not the best location. From my experience with vbar 3.6 the mounting location and type of tape used to mount the sensor require fine tuning. Engine vibration was the cause of the issues so a smooth running engine will help.

Zeal may be needed for v3 but probably not for 4.0. Here’s why, when I ran v3 in my 600n the tail drifted a bit. The sensor was mounted up front on the plastic mount above the two cyclic servos. I switched to using two pieces of futaba gyro tape and most of the drifting was resolved but not completely eliminated. My next step was to use a metal plate in between the tape like the 611. The metal plate would filter certain engine vibrations. Zeal was on my list to try but when I switched to vbar 4.0 all the tail drifting went away with the two pieces and no plate.

Zeal tape may be too soft. Vbar should work the best running the tightest gyro tape you can run without drifting.

Regards

Charles
