My HCity order has shipped. I just made a new lower frame so that I can attach my Askman camera mount. I'll take pictures tonight after dinner.

Hey Bob - Yes I put the camera on it today and got some forward flight - still having issues with trimming - Near the end of my flight I had a crash that broke the tail boom - kinda nice to run to the table saw and make a new one - I am working on the video now - Thanks

Mike

If you order what I have listed, and follow the plans, your tricopter WILL fly just like mine does. Ask Mike, he'll tell ya'

Hi Bob D, thanks a lot for your helpful answers.

Ok the gyros are critical and they are the most expensive component. I have to take into consideration.

Another idea: for indoors flying would it be possible to design a bumper frame around the tricopter to prevent the props stiking people or stationary objects.

I don't know if they'll work. When you get them tell us. I wish I had a better answer. Out of all the gyros I tested the telebees are the best, gws pg-03 is second, and nothing else I had worked.

I had thought about a bumper too. If you extend the arms a couple inches past the prop arc, then use 1/8" carbon or fiberglass rod to join all the arms in a big circle. It should work, and not weight too much.

Bob- Thanks for taking the time to detail the build and help everybody. I had seen the multis in the past but always thought they were too "rinkydink" to be useful. Thanks for showing what is possible!

thank you Bob. Please, don't get me wrong here, the Y-UFO Flies very well in the Simulator, this was just an observation made.

signguy, I saw on one of the other threads that you angled the motors to counter the prop torque, do you still do that, and if so please elaborate.
Thanks for sharing your design, and all the help you are offering here.

No, I don't angle the motors any more. It was just an experiment that wasn't worth the effort. The rear motor is tilted to counter torque, thats all that is needed.

Thanks signguy, that's what I like, the KISS method. Always makes things easier.

First off - another huge thanks for the thread here!! Never really got involved w/helis but have read a lot of threads on the tri-copters before. They always sounded too difficult to set up; some requiring specially constructed boards/etc... This one looks to be the simplest I have found - as well as cheap to do!! Gotta add this one to my build que.

Just a few quick questions I gleemed out of reading through here... I could have sworn I read someplace in this thread about using a 'reversed' prop on one of the motors? Maybe it was in a different thread though. Regardless - does one of the motors need to turn opposite the others? That would make sense to me (I think)...

There was also something mentioned on the props running in different planes? Was that a design issue or should they actually be in different planes?

No need to run one prop the other way, it will limit your prop choices more than any gain in efficiency will be worth. The props running in the same plane, was me talking about a prop I had that was balanced, but still shook like it was out of balance. When viewed while running from the side, one blade was tracking higher than the other ( as if it had more pitch ) . It was probably bent slightly in a crash, and went unnoticed.

Get lots of extra props, and maybe an extra motor ( cheap enough )

Have fun
