Hey Guys

here is video from onboard the Wii micro tri. I have the go pro at the CG in its case, upside down under the tri. No landing gear, so a hand launch and catch are required. The gains are a little too high, but its not bad! Remember, the arms are only 8" I suspect could eliminate the slight rocking with some quick adjustments. This tri will fit, fully assembled, in one of those "aluminum" cases that home depot, and harbor freight sell. may not even add LG.

Micro Tri on board (6 min 38 sec)

Great landing at the end! Is that on your foam mount or rubber tubes? Also, were your gains at 6?

Finished wiring the Arduino and figured out how I'm mounting the boards.

Looking really good, Tim..

I think I am going to try this next.. I flew mine some more today and busted it up again.. Going to build a new airframe.. I've got some settings wrong or the DT700's are not so good for tricopteren..

I'm not sure what my problem is, I'm starting to think I've got a bad gyro as I replaced my ESC and the left motor is still dieing on me at really bad moments..

Are you flying 2.4 or 72mhz?
Never mind... I watched your crash video and see that it's 2.4.

What are the little connectors in Post#15? Looking forward to seeing the test flight.

They're servo connector posts. (Male & Female)

almost all motor cut out are a bad connection somewhere. Sometimes its were the motor wires enter the motor, under the shrink wrap. Sometimes its a solder joint at a bullet connector. I would reheat all your joints and flow some more solder in. I had a joint that looked good, didn't pull apart when tugged, but was the cause of 4 crashes.

Hey Bob,

As an FYI... I checked my ESC grounds last night and they're all good. Measured tone from ESC battery ground to ESC servo plug ground.

Yeh, I'll give that another shot..

here are the close ups Tim. The last one shows the connection board for the new copter. Its just the pins from the arduino kit, and perfboard from Radio Shack. two rows are soldered together + & - and the last row gets the signals from yaw, and the speed controls. The little connection board really tidied things up.

Bob, That's a whole lot cleaner than my setup at the moment. Thanks for all the help on this one! Can't wait to get it in the air. (Unfortunately, it'll have to wait until Sunday or Monday as I'm traveling this weekend.)

Well, here is a video of me firing up the T-Wii. I learned a valuable lesson while wiring this up. Don't reverse your ground and +5 going to the servo... I smoked it in a heart beat. DUH!

Thats cool Tim

I just posted the sketch for the camera trigger on Alex's thread. It was not too difficult, but I did have the brackets in the wrong place for a while. I need to start really learning this. I can see a lot of other things to do with the rbbb's.

I put the sketch on the board that had the cooked processor. I bought a new one from Modern Device to replace it. I had cooked a couple pads off the board trying to desolder stuff, now it wll sit on the camera housing and be an interval timer.

Hey Bob,

Is this the line of code that adjusts motor idle speed at start up?

// *************************
// motor and servo functions
// *************************
#define MINCOMMAND 1000
#define MAXCOMMAND 1850

I'm back and figured the idle issue out...
It's in the first line of code.

(See pic)

Figured out the idle issue... (0 min 14 sec)

T-Wii Maiden... No trim adjustments & stock PID #'s

This thing is rock steady and will only get better as I fine tune the PID settings. The throttle control has to be the best feature. I was able to take it up 50+ feet and quickly come down with out any see-saw action. Amazing!

Thanks again Bob for all the help and thanks to Alexinparis for creating, testing, & sharing the code and GUI freely for all of us to enjoy.
