Tune Your Muti-rotor Part 2

by ycopter | March 9, 2014 | (20) Posted in Tips

This is Part 2 of "Tune Your Multi-rotor".  In this video I explain the benefits of using higher propeller speed and fast ESC firmware, plus an overview of the Ycopter Quadcopter design and an update on some of my recent projects.

Please leave your tips, questions and comments below, that way we can all learn more about producing professional quality aerial video on a DIY budget.

I love the idea of using the GoPro mount for the gimbal as well - swappability like that is very cool.

Yes the GoPro gimbal mount works well, really quick and convenient to change from fixed to stabilised camera.

Very well done. I'm still learning about this R/C stuff, and the info is fantastic. It's videos like this, others from the FliteTest family that I find very useful. Thanks to 'Y', David, and Josh & Josh for all your efforts at helping the hobby. : )

Zeigmont, thanks and comments like yours make all of the effort in sharing information worthwhile, I am sure it won't be long before you are able to help others.

Love the swapability and the standardized connectors! What sort of connectors are those? How many pins and what do you have assigned to the pins. Presumably 12V, ground, video, audio and some other stuff?

Hello and thanks, the connectors are known as Multiplex and have 6 pins. On the gimbal I have positive and negative from the main flight battery and two connections for adjusting pitch and roll. On the FPV module I have positive and negative from the flight battery and two wires connecting the GPS module which is at the back of the machine. Both modules are self contained with step up and step down adjustable power modules, the FPV module also has an OSD board. The FPV module is very compact which means all of the wiring is short and neat, this aids reliability and reduces the possibility of interference.

Great work! This was full of practical information. Presentation was awesome. I'll be watching it again and taking some notes. This kind of knowledge is usually hard earned. Thank you for sharing your experiences!

Thanks for a great video. Thoroughly enjoyed the content, your presentation and your footage. I'd be really interested in more information on your modular connectors and also your fabrication process. How do you mark and cut out your fibreglass sheeting. Your mini quad design looks very promising. Thanks again.

Thanks. See the comment above to "kenc3dan" for details of the connectors. I print out the CAD drawings at 1-1 scale, then I use thin self adhesive to secure the printed plan to the fiberglass sheet. I normally cut two sheets at a time, again by using the thin self-adhesive tape to fasten two layers of material together. I cut it with a "rod saw" held in a Scroll Saw and finish with round and flat files. I lightly centre punch each hole and then drill initially with a 1mm drill. I use a small pillar drill to ensure all holes are accurate.

Great video. I am a big fan of your quad designs. Could you give me some more details on your Mini Quad shown in the video? Does it use the same prop size and motors as the larger quad? If possible it would be nice to see some plans like you had for the larger quad - maybe a link? I have 4x the NTM 35s as on your larger quad but would like to utilise them on a smaller platform for easier transportability.
Thanks again for posting these videos and sharing your experiences, it really does help us novices out there.

Hello Thomas, thanks for your feedback. The mini quad uses NTM 2226 1100kv motors with APC 8 x 3.8 slow fly props with 4S 2200 mah lipo. It has a very high power to weight ratio! This design would probably work with the larger 3530 1100kv NTM motors even though the extra capacity (weight) of the larger motors would not be required. The mini quad is still a prototype, I will publish the design when I have finalised it.

Hello Ycopter.
I shire would like to build your mini copter, got all the stuff. Great tip in your other post about cutting PCB with a tile saw, that stuff is tough.

Wow, that's some pretty excellent engineering skills you have there! Are you an engineer by trade?

Thanks, I was trained as an engineer but now have nothing to do with engineering in my day job.

Nice work! Well done! I've been looking for a new multi rotor project and you mini quad design is eagerly anticipated!

Thank you!

Hi and thanks for the feedback. The mini quad is flying fantastically well, I'm really pleased with it, but it is a prototype and there are things I want to change before publishing the design. I am investigating having the frames CNC cut in black G10 material. I will post on FliteTest as and when they become available.

Hey Ycopter!
Thanks for the reply! I've been wondering about your mini quad and could not find a proven 350 size, which I would prefer over a 250 size. So if you follow the work of Black out the drunk (he he:)) and the Blackout 250, you could do that too. I built an batbone from G-10 and it took me a month and $20.00 of scroll saw blades. If you will sell the 350 frames I would shure like at least one. I would like to support your work as I'm sure others would too. I wish this site had a pm function.

Dave.

Hi Dave, yes all of the available mini quads are too small for me, the slightly larger size makes the resulting video much smoother but still great fun to fly. You are right cutting the G10 is not fun! It would be good to be able to PM you, you might be able to send a PM to my YouTube channel if you can work out how Google+ works!
