Bloody excellent as usual. Thanks Andrew. I turned to scratchbuilt planks because I got sick of buying parts for helis and my quad. I much prefer to collect the largely reusable electronics and then scratch an airframe from cheap junk, foam and wood. Being able to rebuild cheaply and confidently sure takes the fear from crazy flying and the sting from crashing. This looks like a winner.
G'day Andrew. Another good video. You made me dig out my old tri & blow the spiders off it. Still have to learn how to fly the thing properly though. I know you mentioned SimonK flashed ESCs, but to second your comments.. upgraded ESCs improve the control enormously. Really enormously! I'm sure you've got the background, but for other readers: Default / traditional calibration ESCs have usually been programmed to smooth out throttle transitions - allowing for a nice smooth ramp-up / down of your prop. Great for planes, but not so good for multi-rotors (I assume that gun 3D pilots would also want to use mutli rotor cal ESCs?). Most ESCs use one of 2 family of controller chips to run their firmware; either ATmega or SiLabs. Simon Kirby (SimonK) developed some revised frimware & tools for ATmega based ESCs, and OliW has done the same for SiLabs. Plenty of other have added to their work. If you want to flash your own ESCs a good place to start is docs.google.com/spreadsheet/ccc?key=0AhR02IDNb7_MdEhfVjk3MkRHVzhKdjU1YzdBQkZZRlE#gid=0 where you can work out what chip you have, & follow the links to various guides from there. Also OpenPilot have a good article on doing the SimonK thing wiki.openpilot.org/display/WIKI/How+to+Flash+SimonK+to+ESCs ... and OlliW has a good guide here www.olliw.eu/2012/owsilprog-tutorials/ A big thanks to Simon, Olli and everyone else involved for their great work! Cheers.
Lex Dysia Thanks. It's interesting, but at this stage I'm not finding a great difference between the Plush and Afro simonk ESCs. There is a difference but it's not night and day. Maybe the Plush ESCs are OK for multirotors or my motor choice and skill level is masking the difference. Onward and upward!
Andrew Newton Fair enough. I found with standard ESC cals the controls always felt a bit disconnected from the copter irrespective of P & I values. Height control in particular was very mushy. Slow flying in stable conditions wasn't too bad, but anything more than that was a bit of a challenge.
Hi Andrew Great build video Simple practical and clear - just whats needed thanks for the putting in the time to make it I will be putting you guidance to use very soon regards Hans
tudo bem com vç. legau seus videos poderia da ama ajuda com tricoptero , estou montando um tricoptero mas estou com problemas no motor de cauda , ja quimei seis esc fasendo teste, a final o esc começa normal depois altera a velocidade e esquenta muito termina quimando o tricoptero fica saculeijando pro lado e outro… alguem poderia me dar uma força. agradeço de coraçao
You may want to try mounting the board without the foam stand offs and see if there isn't some improvement in stability. The more rigidly those are mounted, the better along with very well balanced props. Excellent project.
Very good instructive video (as usual), your explanation of the frame being a skeleton to hold everything together is spot on. As previously suggested your anti vibe pads for the FC are too big, try 3m double sided tape. After watching I feel the need, the need to build another tricopter :-)

Scott Jenkin Thanks Scott. I love re-purposing materials
Fist class effort again Andrew, that's quite a neat setup and it worked very nicely, well done
loonypics Thanks, it works much better now with some balancing and tuning
G'day Andrew.

I opened up my Simple Copter frame that has laid undisturbed for a year thanks to you :-) I have too many projects ..............
Stephen Gloor Ha, mission accomplished.
was thinking about buying one already put together, but I really like the idea of building one more feels cool to have your own custom build tricopter
+notquitepinoy You're right. You learn a lot by designing and building your own, and can buy a carbon frame later.
I got frsky x9 transmitter how is the setting to tricopter like this thank
+michael colon Michael, you just setup a normal 4 channel plane model with a switch for self level mode. I can send you my eepe file.
It is so simple. Thank you for posting this video.
Love this. this is my next step and cant wait to build one! Keep it up Andrew
Excellent Phil. After this you might want to consider buying some components from RCExplorer. The arms, body plates and tilt mech are all very nice.
Can install8 drives on the .kk.
what was the final weight?, I'd imagine around 700 g or less
Sorry I dont recall the weight but that sound about right

Sorry Felipe, I dont know much about tricopters. Maybe you need a bigger esc or something wrong in the FC setup?
Motor himodel 2212-1000kv? Or 2212-1400kv?
I used SunnySky 2212 980 on my final version
what is the needed materials?
+Sam Tagalog Watch the video
Very well documented. Thx alot! :)

yellowbusguy Thanks I'll try that.
Vibration mounting the board will still help.

cynr100 Build Build Build! Thanks man.When I get a calm day I'll try with and without the foam pads, nothing but 20-30kn for the last 3 weeks!
Very clean and objective build... is that your first multirotor Newton?
vitor hugo almeida barros Thanks, this is my second. I used the components from my first multi rotor for this demo model.
thank you for this video it is very simple
so cool home materials building thanks buddy
Cheap and cheerful
very very goood perfect
Nice simple easy to understand as usual. However the programming is way out of my league I'm sure.
Trouttaranaki There is no programming really. Just making a few selections in the menu.
wow gradpa
มันบินเด้งไปเด้งมาหัวใจจะวาย
Yes, dangerous machine
