Sure. But basically, all the subjects are getting cut off.

Can you pm me a screen shot of what you mean

Gaza - can you make the subject line section in the forum topic list wider? It's cutting off the subject field really short.

Good for you!  ~~

Had another negative encounter, it's been a few years since the last one, just an uneducated ******, going on about drones being illegal yada yada yada.    :-/
Still that didn't spoil my flying time, had an absolute blast  ~~

D.B. you tightwad.. :cool:

DB that just means you have shed loads of props in the first place ;-)

Just had a thought, even with all the crashing I've done, I haven't bought any replacement props in over a year ~~

May the sun shine and winds be light for BFU#8. Son't forget lots of vids for those of us unable to attend.  :D

How does your Y6 compare...

How does your Y6 compare to a hex rotor V?
Stability and endurance?

Hi John,
Recently I converted my hex V to y6 because I wanted to reduce weight and make it easier to transport. I had only one concern.. efficiency but after the first flight test I had big smile on my face. LOL :D
In my particular set up there was 7-10% loss of efficiency
/test was without payload/
Total weight reduced was ~680gr.
Another thing which is not that relevant but it';s good to point out.. in order to make it foldable I had to move esc';s close to motors which helped with the cooling.

In terms of handling:
- easier coordination
- faster and stable descending
- yaw works better

Note that my set up is for calm weather and most of the tests where perform in such weather.

AUW - 4940gr
(Including 2x5000mah lipos and Canon 60D with 50mm 1.8 lens)


P.S.  forgot to mention that with the y6 there will be no such drama if motor Or two(upper ones) stop working in mid air. ;)

Thank you for your reply Evgeni.

I must say, that is a good looking aircraft you have there, the build looks superb.

Thanks for the information, it has encouraged me to continue the design I am working on. Your comments on handling seem to indicate some good advantages of flying a Y6 over a hex V. I was initially worried about the loss of efficiency too but have decided I should be able to accept it. I am guessing your aircraft is somewhat larger in the motor / prop / battery department as you are flying a much greater payload than I. I am hoping to fly a FPV rig and maybe a GoPro (if I can afford one) on a servo based gimbal. This is my first time with a hex and Naza FC, and only my third build, previous aircraft were quads with a KK2 FC. I am guessing at having something completed in the next few weeks and will post pictures then.

Thank you again,

Best regards,

John A.


John by chance do you have yaw issues when you converted to y6. I cant seem to iron mine out.

Hi Toledodave,

You are much further along than I am Sir, I have most of the parts for the build but am still at the CAD drawing stage at the moment. I wish I could help but I have not even flown a hex yet :embarrassed Having said that, as I understand it, yaw is achieved by varying the torque effect of the motors so I would think if all props are equal and all motors are equal and the aircraft is balanced, it may be worth checking the ESC calibration?

Best regards,
John A.


Hi John thanks for the reply.
    Yeah as i understand your right. I dis have them all one way on top and all opposite on bottom but had so much trouble with yaw i noticed in most recent sketch update it was recommended to reverse the rears directions top and bottom and yet i still dont have yaw control. Pitch and roll are great but yaw is crazy lol. I must be overlooking something. Gonna relevel again and see where im at. Wish you luck on your build.  If i can ever help dont hesitate to look me up.

Prototype Y6.
95% complete.
Achieved reasonable hover, requires tuning.
FPV system awaiting install.

Whey hey, and up she rises, maiden flight with no surprises.....

After spending some time working up the courage to make the Maiden, I finally took the aircraft into the garden. Powered her up and waited for the GPS lock....heart rate at about 120bpm. Armed the motors and checked all were running ok, tentatively throttled up....and she lifted....held very well in both altitude and position (<2mt on position) Switched to ATTI and cautiously manoeuvred around a little. She seems quite responsive. Back to GPS mode and a wonderfully stable hover. Switched to Failsafe, LED flashes yellow and shortly after, she began to climb, guess the failsafe is working but switched back to GPS by waggling the switch before she flew too high (after recent posts I am paranoid about having a fly-away) Back into a hover and out with the ';phone to grab the photo. LED starts blinking red, batts low so bring the throttle stick down a little and experience a very nice decent and landing. Throttle to 0% and the motors cut at 3 seconds...

All I can say is that it was a wonderful anticlimax :smiley: and that I am very happy with the aircraft. I will inspect the airframe tonight to make sure all is as it should be, and start the fitting of the FPV kit.

I would like to thank the forum members for the wealth of information that has been made available, and to everyone who helped and encouraged me over the last few weeks.  :beer2:
