now don't laugh fellows, but I am still flying my helibug with flybars. it flies great but lately have been thinking about making it into a flybarless machine. what exactly would I need to do and would a 7200bx flybarless unit work. I really don't want a unit that I have to hook up to a computer to set up. any info would help. thanks.

whats the shaft size on your heli 10 or 12mm?

i know nothing about helibug but you can make any FBL head to work as long it fits your shaft and blades you can even convert you current head to FBL

RJX makes FBL heads for 10 and 12mm main shaft

then get a controller Brian and Vbar needs a smartphone or a computer
Futaba and JR does not never played withs JR but Futaba cgy750 works very well and easy to program

not sure about the others brans

so get a head and controller

then setup the linkages so the servos have 100% throw with the controller and get 10 to 14degree of pitch 10-12 is a good starting point

this is just the basics

the negatives of FBL is its puts a lot more stress on your servos and battery so you will need some good servos

kinda hard to go wrong with any quality brand of FBL controller...

Use whatever brand FBL controller your TX is to get the most from it....upgrade your cyclic servos to get at least 121/0.10 second types and you will be fine...and upgrade you RX pack/BEC as FBL systems tend to consume more power.

lots of support here on most any brand.

and no laughing...I still have a Trex that has a flybar....it flies perfectly fine and no need to change it over....

my gassers on the other hand needed FBL...the flybar versions tracking and holding really sucked...a CGY750 and an Align FBL head fixed that right up.

showing a preference will only get you into trouble, 90% of everything is crap...

Skokoom makes great units the older versions don't like the vibes too much but newer ones are fine. I haven't tryed the newer ones like spirit or brain but I keep hearing good things about them. Vbar is another good brand and I plan to use that on my gasser. You can pick them up cheap on the used market just make sure that they have the PRO software. That enables you to set parameters. Oh and BTW you do want to set them up with computer. I know it sounds like a hustle but all the fine tweaking and parameter setting is done this way.

Torque, don't be intimidated by going flybarless or the ar7200bx- both are a great choice and you will wonder why you waited so long. I was in exactly the same spot as you only a short while ago and I finally took the plunge by converting one of my smaller nitro birds first. I started with the ar7200bx as I had heard good things about them and I have a JR DSM2 radio system. It is really quite simple to set up if you just follow the steps in the manual. There is no computer required- you simply use your transmitter sticks and follow the series of lights on the unit itself. It truly walks you through the setup. A few points of note- physically the controller must be mounted perpendicular to the mainshaft with the plugins facing either front or back to work properly. Also, you will need a dsmX satellite as a dsm2 satellite will not work. Again, once you do this you will want to start switching everything over so be prepared! I am currently In the process of converting my helibug Raptor (you didn't mention which helibug you had?) to Flybarless using the thundertiger e700 head parts, mainshaft, and the ar7200bx. It is coming along nicely and I can't wait to try her out. Good luck man, I hope you decide to try it out

did you ever consider using a multiblade head on your helicopter. It sure looks cool enough to warrant one....

Absolutely. Budget limitations have kept my 'scale' aspirations at a minimum for now though.

I have a trex 700 converted to the helibug gasser. it has the 610 servos. someone said I would need to get a shorter main shaft is this true. could I fly my non flybarless main blades.

so what I am getting so far, I would need a flybarless head, a 7200bx with a satellite rec. I currently am running a 3000 LiFe battery. I am guessing I could still use that?

You can use FB blades, they are lighter so the heli will be quicker than with FBL, but they will work. When you need to replace them is a good time to try a set of FBL.

AR7200 is not the best choice for a gasser, they are not very tolerant of vibes. Some others that would work better are Helicommand/Bavarian Demon, CGY750, or an Ikon.

3000 mah is plenty, expect to consume 300-400 mah per flight.

Depending on what you are using now, You may need different servo horns to get the proper resolution.

Torque, I can't speak to what you need mechanically to convert your trex as I have never owned one but yes, your electronic list is correct and your servos will be good. I use 2100life in all my machines and it works great. As a side note, prior to going flybarless my Raptor 50 consumed about 250 mah per flight. After going flybarless with the ar7200bx and making no other changes, it now consumes almost 500mah per flight.

going flybarless

update: I made the change to flybarless. I got a used AR7200bx. on my first outing I went over everything. on my fourth flight one of the servo disk screws came out, not good. you know the rest of the story. it did very little damage. I took it out again this pass sunday. 5 more flights on it. I definitely like the looks of flybarless better. it does fly different then with the flybars. not sure what the hype is all about fbl. not sure what I was expecting. anyway, I am now fbl. thanks for the help.

I like your critique- I felt basically the same way after my first conversion. Glad it worked out for you and welcome to the modern tech.

depending on your flight style you will notice that the heli is easier to fly with out making corrections especially after flying fbl for a while then going back to flybar machine. I switched to fbl 5yrs too late hahahahah

My experience with FBL is it is nice going without a fly bar ,,fine then you only realize how great it is when after awhile you go back to fly bar and really see where you came from. I flew my Min Air 1005 gasser yesterday for the first time in 2 years ,flybar ,mechanical mix and all. Stunning really the difference between this old gal and modern CCPM and flybar less.
Took me a few minutes to get used to it. After the 3rd flight I was used to it and comfortable with it. She does fly great and I will fly it more even though she is made from unobtainium. Before Min Air closed I bought a ton of parts and an extra 1005 airframe so I think I am good for awhile.

Setup is everything, All my heli's can fly far better than I can pilot them
