no language barrier that I know of, lol. You are absolutely right, and when I noticed the incorrectness of my statement, it was too late, I could not edit or delete it. So you are right, for the tri to yaw left, rudder stick goes left, yaw motor tilts right, and the nose of the tri yaws left. Simple, eh, lol.
I did fly it but, man, I can't set it up anywhere near your stability. So I build a MultiWii board with MultiWii+ controller, Arduino mini and Bib's Super Simple Shield (all in RC groups),and it flies very stable and level. I spent over 30 hours hovering and changing the settings on the KK board, where al what I wanted was achieved with MultiWii and default settings. Weird or not, I like MultiWii more. I used the same platform with both boards.
Very nice and stable flying. I just finished mine using David's plans and it is not nearly as responsive as yours. What size props are you using? I put on the EP-1147 and just ordered EP-947 to see if smaller props make a difference. Also, my motors do not start at the same time. Should the ESC's throttle range be set individually or can they be done as a group after they are soldered together? I did mine as a group.
In the video I used 10"x3.8" APC propellers if I remember correctly. After some hard landings I did not have any spares, so I tried some 3-bladed 9x5 (GWS?) props from eBay
I was surprised to discover that the smaller, softer props made the copter even more stable! I think you should try 10x3.8, or possibly the 3-blade, but the props you ordered may also work better.
I don't remember how I calibrated the ESCs, think I did them separately. Don't think it matters..
Sorry, - I forgot the correct dimension on the 3-blade, looks like it's 9x6! Make a search for "Treblada tri i vinden" here on YouTube and have look at the tri flying in the wind.. I'll check the dimension when I get home...
Very good use of lights, nice visibility. Are you using the KK board 5.5e David recommends (Singapore one) or some else? Did you have trouble setting it up, or for you it was a straight up process?
@pajonate Yes - the KK Plus 5.5e.. No problem setting it up with existing firmware. Should have ordered Serial LCD for XX firmware, but I am happy with KK Tri v1.5..
@jhindoy Thx, I am starting the build myself, based on David's design, and I got the KK 5.5e board (mine is the one with LCD and XX firmware). I hope not to have issues with it, too, but time will tell, lol
@pajonate Good for you! You did what I should have done - you will have more programming options. I saw from your YouTube site that we are sharing the same interest in the Polaris and keychain cameras :-)
I finished my tricopter, and when I wanted to do the maiden, my yaw servo is moving from neutral position to the right by itself, which causes the whole platform to rotate clockwise. My platform has no supports on the arms, only one central support beneath the battery, so the rotation starts while I am having a little throttle, and after that it becomes so uncontrollable. Full rudder in the opposite direction is not reducing the rotation. I didn't even try to lift it up. Any advise?
@pajonate pajonate, You need to check two things - yaw input and gyro response on yaw. Moving yaw stick left should result in rear motor tilting right (cw). If not, reverse ch 4. Gyro response: Check by turning tri cw - rear motor should tilt right (cw). How to reverse servo and gyro: Please read the forum.. Hope this helps - good luck!
thanks for the response. I'll check into what you said. I know that my yaw servo direction movement is not wrong. Pushing the yaw stick right, move the servo to left, and the tail yaws right or CCW. So that is OK. I have to see the yaw gyro direction, with no props, to see what i'll be getting.
Thanks for the info. I ordered a set of LED's to mimic your tri. I've flown heli's for a few years and hopefully can get to flying the tri like you.

Sorry for late answer...
Maybe I am confused, but I still think my description is correct. Guess it doesn't matter any more as you probably already made it work :-).
(My description is based on copter rotation seen from above and servo/motor rotation seen from aft).
Take care :)

I liked the battery weight testing. Smooth.

Sorry, no I don't.. You may do like I did - use plywood, or order carbon fiber plates at HobbyKing?

I am making the same design from rcexplorer but i cant find the fiber glass plate, do you have any ideas where to get it?
