HI Alan. Thanks for the offer. It looks like you're based in San Diego, which is where the 3D Robotics team is. Would you like to come by and meet the team?

It's good to see Arducopter user group.

and I hope I can get a answer here for my quest, that was not responded on my previous discussions that was posted in technical support section.

pleae help!

For my Tilt Rotor Quad Project.

I am looking for ways to add I2c sensor board SEN-10321 to APM & Oilpan for my project. Oilpan already have Accelerometer and Gyros built into board, and my project need to mount them in seperate location (under the motor support in my project picture), since this board have same sensors  as Oilpan and also include same Magnetometer. I thought this was my best candidate for my project and also, I don't need seperate Magnetometer anymore.

Sen-10321 needs 3.3 volt, and Oilpans's I2c has 5v. Do I need logic level shifter and I2c splitter for this connection? and what and how do I need to change code to do this?

If I can use both sensors (SEN-10321 and Oilpan's built-in without disable them), and somehow address them in the code will be wonderful. If that is not possible I will just need to use remote sensor board.

I am not good at programming, so detailed instruction will be woderful.

Took my quad for its first test run today and......It Flies! . Thanks Chris and the arducopter team. Best graduating present ever!! Made my day, all the hard work finally paid off. Any room for a mechanical engineer at DIY Drones?

I have happily been flying my AC2 for a while now, and its currently in pieces, as I am converting it to a Hexa. hope all goes well, will probably post a review and some pics here soon...

Thank you for the invite to this group. I am still working on my first Quad Drone. I have built models and flown RC for years. I would like to share a link to John Searl and think many of you will find him fascinating. The video about him is amazing.

Many thanks for the invitation to this group.  Of course any member who is in the UK is enthusiastically invited to our South of England 'Drone Zone' event which is happening on the 12th June.  This is an informal get together of drone enthusiasts and we are encouraging anyone who has a drone to bring it along.  The good news is that the event is FREE!  Hope to see you!  Details are on the UK UAV fliers forum...


If you'd like to know more, please email

Cheers, Nigel

Hi all,

I have three quads of varying sizes and would really like to get them flying. However the weather here in North TX has not been very cooperative. The wind has been blowing from around 10 - 15 mph since the middle of last week. Gusts have reached 25 mph. Definitely not good flying weather and it is expected to continue for the rest of the week. However, I have learned quite a bit about what not to do concerning getting my quads in the air by learning from the experiences of members on this Forum.
