Hi all

Here is a video captured by "shauntot" during this morning (Feb 20, 2007) funfly in Bishan, Singapore.

Nothing fanciful... just flying around from left to right and left again.

Direct download and play using FLV format player:

{Thanks shauntot for the video }

can you do the video in a user freindly format like Windows Media Player by chance???

I am sorry about the video. If I'm the one capture and convert, I will definitely convert to either WMV or XviD format. The video was capture and converted by "shauntot" himself.

EDIT: I might have chance to convert it to XviD if u want to...but where shall I post/upload it?

Best tihng you could do is convert and upload to youtube, it is fres then you can just link it. Just a thought.

I'm a technology guru and have no clue what format / encoding .flv is. Do you have a link for a player?

Player for the file.. Free download. I used it and it works great..

Nice video. That thing looks very stable.
Time for some 3D.. lmao j/k..

I'm new to this multi-blade head concept...how do they fly versus a flybar equipped model? I have read a lot about additional gyro on the cyclic as well weight in the front end to compensate for a balloning tendancy in forward flight. Is phasing a pain on a small electric heli? Does the following hold true:
More blades= more lift= lower motor rpm and more runtime?

How does flight time compare to a trex 450 set up for 3d?

I've never considered the scale aspect of heli's before, mainly because of the expense involved, but being able to test the waters in the form of a small electric is an excitng prospect. It would be an interesting addition to the fleet...

Hi all

Yes it is a macromedia flash video format. U can either download it and play from FLV format or u can view it in stream format.

If you prefer stream format, try this URL instead.

Flybarless heli tend to fly a bit different from normal heli. I learned from my 2,3,4,5,6 blades, the more blades u have, the more stable it goes... but also notice that the more blades u have, the easier it is affected by wind. Maybe due to it has larger lifting surface area that it can pick up the wind easily. Yes, flybarless without gyro do have the tendency to pitch up during forward flight. Using gyro on cyclic, it can make the above mentioned more stable.

For phasing, if u prefer linkage from swash to blades to be straight line, then u need to phase/offset it using your TX or some onboard device. If your linkages are in 90Degree phasing, you do not worry about the mixing.

Yes, more blades = more lift... provided your motor/esc/batteries can handle the load. More blades meaning u can run in lower RPM. If u using high KV motor but u run in low RPM, it is not very efficient. If u use lower KV, like > 1200kv but < 2000kv for 4S batteries, u can actually run in much longer flight time.

As for 3D, i prefer to fly in sport or scale flying. I gave up trying to fly 3D long long time ago. With that, I not sure how will it perform in 3D. I think if u really want to go 3D, u should not use 6 bladed instead. Maybe 3 or 4 is enough.

Sorry, I meant how does flight time compare to Trex set up for 3d. A trex 450 doing hard 3d with good set-up and batteries gets roughly 6 minutes; does the multiblade trex get good flight times doing "scale" style flying? My 450 is set-up for 3d, but with mild flying I can get 7 - 8 minutes.

Sweet
whenever I tried a multi head it was always very dificult to fly. Are you using a mixer?

First of all, thank you everyone for the good comment and interest.

adamsz06:
Well, I believe the flight time will definitely increase. In 3D, your motor RPM is high...very high. In these, using lower KV motor, you can actually achieve longer flight.

walpole flyboy:
The first few versions of my flybarless are all in mCCPM (TRex HDE/XL) configuration. I do not use any mixer at all. Being mCCPM, I can easily use gyro on the cyclic by simply connect between RX and servo.
Recently all my flybarless are converted to eCCPM 90 Degree. By going eCCPM 90Degree, I can have better servo power in the cyclics and collective (especially in flybarless) AND most importantly, I can use cyclic gyro as well. What I did was that I use 2 V-Tail mixer to create a simple eCCPM 90 Mixer. Thus in term of TX to RX point of view, it is just another mCCPM. Therefore, I can use gyro again.

spames:
All the multibladed head that I tried are all hand craft, home made. Swash plate wise, it is just another Align swash plate. I just drill a different hole and tap it.
For 2, 3 and 4 bladed TRex, u still can fly with 2 bladed tail. Goes anything more than that and if u are using normal TRex main blades, it is advisable to go more tail blades in order to achieve better tail authority.

Would be so kind to post some pictures of your head set up? you know some detailed pictures so we all can get a sence of what you have done. I been thinking I want to try my hand at making one if I can't buy it.
