Electronic assisted paddleless head

Anyone flies here? I saw it once in the youtube. It is more scale.

If you're talking about the V-Bar setup by mikado logo, then I think you must be joking.
The price itself will put people off just by flying it. We're just talking about the price of the system, haven include the V-Bar rotor head....

Nevertheless, surely it would be nice to own and fly one.....

But there are always alternative solutions to this, do a search and I'm pretty sure someone here has already done it before.... Cheaply...

Calling Superhornet! Someone is looking for you and your flybarless Huey!

[Super-Hornet]

Ehh.. u also "Swashhead".... right?

For simple 2 bladed TRex/Raptor, yes it can be easily convert to 2 bladed flybarless. U can reuse back the original rotor head as well.

Remember that it is recommended to have 2 non heading hold gyro for the cyclics. The purpose of those gyros is to mimic the flybar+weight behavior.

Hi Superhornet, please provide the link to the youtube video of your Huey flying at Bishan (my company internet blocks youtube access). IMHO, that's the best flying model made from 1:18 scale fuse!

Ehh... I too do not have the YouTube link... But I believe u can find the URL/Link in this forum.

Do you feel the different as compared to flybar type in the normal scale flying? Also, do you think those cheap GWS gyro will work? Any reference article from the web? Would like to see you flying next time if possible Thks

[Super-Hornet]

First of all, remember that the V-Stabi by mikado is more like a pro type. What it does is that it also mimic the flybar characteristic as well. They even have extra (but optional) pressure sensor to sense the forward/side motion (depend on where the sensor is pointed to). This sensor help to reduce the behavior of pitching up in flybarless configuration.

Flybarless (2 bladed or multibladed) behave differently as compare to normal flybarred design. Flybarless with gyro will make the heli much more stable and predictable to fly...but no matter how, the flight characteristic still slightly different from flybarred heli.

I once let "koon" to try out my 6 bladed heli (with Counterclockwise rotation)... what he said is that it fly like a real heli.

Oh. I'm using GWS PG-03 gyro for all my TRexes..except tail (Ehh.. all my TRex are NON flybarred design )

I believe the Futaba G190 also can. Overseas, some uses telebee gyro. For bigger heli (people who is rich), some uses GY401 also. What u need is a non heading hold gyro will do. If u use GY240/GY401, then u have to turn off the AVCS

SH,

Since on the topic of flybar less. For two bladed flybarless rotor head, needs extra two gyros to assist the cyclic control. How about three blades and above, do they need the extra gyros?

[Super-Hornet]

The more blades u have, the more stable it goes.

2 Bladed without gyro, very difficult to fly. In TRex size or smaller, it is like impossible to fly forward. Hover still ok. In 3 Bladed, u start to able to fly without gyro but heli is slightly unpredictable. Some main hub design will tend to cause heli to pitch up during forward flight or fast forward flight.

In multibladed, with gyro will make the heli fly more like normal heli. More stable. In hover, it can be very stable.

The more blades u have, the heli tend to feel more sluggish. When in forward motion, if u want want to change direction, it sometime take times to response or u need to bank the stick more than normal. (I guess what "koon" initial surprise feeling when he tried my 6 bladed is because of that)

If u ask me, I would prefer minimum of 4. The more the merrier if u are into scale... Oh still prefer with gyro as well.

EDIT:
Ever wonder why U.S. Marine/Navy/Army/Air Force starting to replace all their 2 bladed heli to 4 bladed or more? (Huey from 2 bladed to 4, Jet Ranger from 2 to 4, Kiowa was initially a 2 bladed. Now 4. Cobra from 2 to 4)

Very cool video especially the twin rotors. Fly with a scale body
Regarding the gyros for "elevator" and roll axis, I can understand when the setup is in pure mech x/y 90 degree arrangment. How about CCPM 120 degree? Do you arrange the 2 gyros in 120 degree or how?
If GWS gyro is ~$80, so is about $80 per paddle elimination.
Now a bit regretted to sell away my 4strokes heli. Should have kept it and spend $160 for the flybarless new fun.

[Super-Hornet]

For mCCPM and eCCPM 90, it is very easy to use gyro. (For eCCPM 90, u can just use 2 sets of V-Tail Mixer).

For eCCPM 120 or 140, u definitely need an eCCPM mixer onboard. Due to the way the eCCPM's cyclic and collective move, u cannot just use V-Tail mixer or direct connect to gyro.

BTW, GWS PG-03 can get online from China website and it cost SGD6x.xx only. Too bad Rotor hobby INSIST Do not want to bring in any more PG-03...claiming that no one want PG-03 anymore because ppl go for GY240/GY401.

Hi Swashhead

Have to stop hobby as I had some eye problem lately. Still missing the fun ....
