Flybarless Rotor Head Systems > T-rex 600N Flybarless V-bar

Just thought I would load up a few pictures of my flybarless attempt. After a lot of reading and searching went for the V-Bar system, looks great quality and has outstanding customer support along with input from Runryder Members its great.

My setup is as follows,

T-rex600N,
Kasama Head,
Vario Swashdriver (10mm),
Quick UK Swash,
Carbon pushrods,
V-Bar.
Lowered head by 15mm for improved CofG.
29mm from centre of hub to ball link on grip arm,
18mm spacing on Align Servo horns,
RotorTech 610mm Blades,
Webra 55P5, Modified OS Hyper Carb, CSM Carb Smart and Magic Pipe.

Yet to be test flown but mechanically setup for +-14 and electronically programmed through the V-Bar. Starting out with 70% DR and dial it in from there. Hoping to get plenty of air time this week so will report back.

Hola MJ
your machine looks great

You've got a very nice setup! I know that the webra makes tons of power with the magic pipe. A buddy of mine has this combo and the power is really amazing. A flying-vid would be

Hey Raz, pretty happy with the way its all turned out. Not a lot to it really when you get the basics right. Glad to help out mate just ask away. Hope to catch you up the field soon. I'm going to take it easy to get the feel right then start to wring it out. I admire your get up and go attitude and it seems to work for you :-) Don't forget about that drag race!! Jono's going flybarless, been specing up his Synergy Today, Dino oh you are cruel!!!

oh yeah , well once i`ve sorted the rex tail i`ll be up for it and when i got the rappy sorted we`ll have another one , maybe get jono and his tank to join in

one thing tho majic , the heli feels so different , so so so different , i flew the rex straight after on sunday and nearly killed it

so roll on summer and we`ll go for it , your system looks complex but i`ll have a good look when i get to the field if i may , will jono convert to your way or mine , ha de ha , well done mate , its gonna be a cracking year at the field

Only the best kit as always Majic! Can't wait for your feedback on how she flys (as I'm hot on your heels with the N9).

Raz, you ever considered joining the rest of us in the real world bud??? Dino eh. Dude let me know when you're up for a man's size heli and I'll get you the spec for mine! Nutter!

The V-Bar system seems to leave the CSM rubbish standing on paper. They seem to have used a novel approach and made it user friendly. Understand they also give some back-up if you need it.

Hope everyone has a happy year's flying!

Going to keep everyone updated and be open with my error's/fndings as others may find it helpful even at the expensive of maybe coming across as a fool :-)

First flight. Prior to going out I checked the collective compensation and as I thought it was reversed. I found it a little tricky to get the right way as the instructions say to reverse the sign, I assumed this to be the value however a reverse sign is not possible. I found that by reversing the Rc channel input and reverse the sense corrected for the compensation and the stick deflection remained correct. I did not however after check gyro sense and it was WRONG so first pickup had a wicked Yaw, no huge drama landed, and changed but could have been nasty.

Tail now sorted picked up and got in to PIO, Pilot induced oscillation on the elevator control, heart in mouth moment landed calmed down. Controls seem sluggish not very sensitive yet as more stick applied becomes way to sensitive. After a few attempts hovering lacking the precision I like became possible.

Off in to forwards flight and it showed its true colours, tracked lovely, fast turns with no surprises, couple of loops for good measure and system worked flawlessly. Back to hover becoming more stable, ran out the tank and that was it. Eventful at the beginning due to carelessness but non eventful at the end.

Bit windy to trim but programming will be altered to try and improve the hovering.

Tweaked the Paddle weight down to 60. Seems to keep up with the input now. Gusting 20kts so decided to call it a day whilst ahead :-)

Hi,

Just a thought... could you use longer linkage balls in the blade grips so you wouldn't have to move servo horn links in. Then the distance between bellcrank balls would be the same as distance between servo horn balls.

Hello MJ,

please do 3 things:

- use shorter linkages at the inner swash ring
- measure your distance between the 2 linkage balls at the blade grips at 0 collective

and then:

- post this value, the details and pics above and your setup as an .xml attachement at the vstabi forum www.vstabi.de (there is an english section) and we will se what we can do for you.

Tweaking the paddle weight down is not the right way in this case.

All the big bits are still attached. My setup was so wrong it was almost unflyable seemed like it had huge delay (Which it did) lol Not sure what happened as I thought I used the T-rex config file so will look in to that another time. Thanks to the guys at Mikado for reviewing my setup and taking time to help me out. Just need some more air time now.

You know Jono's view with that certain product, say no more.

CSM carb smart

How are the guys at CSM customer care these days

Great guns MJ - keep it up cos the rest of us can't

- hope to see you flying soon as the V-bar looks like it needs to be placed on the COOL WALL.

Raz yours flew / hovered with NO electric help so will be exciting to see the two sides of the coin up together.

Jono - your N9 as Flybarless Magnificent mate i shall bring my video camera along when all three are ready to fly together and get it uploaded here for all to see.

Yes I caught the flying bug too !

Well done MJ. Let us know how she flys with the new settings that the Mikado experts have set you up with!

Expect to have the first Synergy done within the next 2 weeks.

It would be good if Pheonix could create a flybarless heli as an update. Would like to know how they should feel. Will have to mail them and make the request.

Managed to test the new settings today. What a difference those settings have made. Flying in basic mode is just about the same as with the flybar setup. Hovering is locked in and tracks really well even with the windy flight conditions.

Next for the setup is to adjust the tail sysyem. Drifting in to wind so think the heading hold value is too low so going to review the PID settings next time out.

All in all V happy, even my dad noticed how stable it was, or it could have been I was just flying smoothly for a change :-)

Nice one JP, like the sound of those custom parts for the Synergy. Sure is going to be some nice kit up the field, keep it up guys.

Well done mj.
can't wait to see it .ive got to do a few more tweaks on the freya this sat and then i'll be happy

Hey Andy, how u doing? Heard the Freya is up and running so good news there. Let the tweaking commence. Got the T-rex pretty much dialed in with the basic mode, bit of tweaking in the extended. Couldn't help myself got the Air sensor module coming and just installed a YS instead so a bit of running in to do.

Can't come over this Sat but next week I hope should be ok.

Catch you soon,

MJ

Just been out with the heli again today. Very windy so wasn't expecting much but all I have to say is WOW!! This heli was never that great in the wind but with the V-Bar it tracks superb, doesn't become pitchy and flew like a rocket.

Put the nose in to wind and Aileron rolled on the spot for 5-6 rotations with minimal if any elevator it just stayed put (in 25mph winds), Flips were lightning fast and true and tic tocs were locked, no tail wagging or aileron turning.

I think over time with this system flying will be even more precise with a degree of stability.

The power difference is really noticeable as well, it climbs out and has as much punch as a 90 but with 50 costs and have yet to bog the rotor :-)

V happy with it all, and top marks to Mikado again for there support.

All I can say is buy with confidence, Its up to you to get the right mechanical setup but the programming side the V-stabi forum is the place for guidance.
