BTW, I just tried the new DEV code on my MultiWiiCopter.com Scarab HexiiKopta with great results! No more need for the PPM SUM device with my Spektrum RX!

Thanks to AlexInParis and friends!

Of course this is a dev code, so you use at your own risk!

UPDATE: I just found out that the P value needed to be increased to 11 to fly well - very strange. Don't recommend the DEV code now..

Thanks John, yes I flew it with an old Warthox board with Wii gyro using the DEV code because I didn't want to modify the board for a HEX and use a PPM sum. So with that said the copter flies great but I think there's something very strange with the new DEV code. With the stock PIDs (p=4) the copter was really soft flight/gyros were not crisp like usual. The only way to get the copter to fly like my others on 1.7/1.8 was to increase the P to 11!

I'm going back to 1.8/1.7 code and will wait for my new Paris board to arrive in the mail. Then a real flight test will proceed.

Cheers,
Jason

Orientation help

I read in another thread that using orange or green blades are the best and easiest remedy to keep your orientation. So I painted the two front blades of my tricopter in orange and it worked really well. Very easy to spot and follow when you are flying. The paint added 1g per blade and I balanced them after the paint job.

Engine clips became loose

Today, after changing the battery, the tricopter started to twitch. When I came home I saw that one of the motor shaft clips became loose. I assume this was the reason for the twitching, since now I can push the prop down without too much pressure.

OK! The HexiiKopta is complete and flying great! The build went very smoothly and quickly. Even the first flight was perfect! The Hexii came out to about 3 lbs. (1360g) ready to fly with the GoPro and a servo-tilt camera mount. FPV gear will be installed shortly as I'm making the FPV gear modular for all my models. Anyways, below is a time-lapse video of the build and the first flight. Enjoy!

Check the other end there is probably a screw to attach the shaft to the bell of the motor.
If not... check if the shaft is all way down in the bell hole.

I used Rust-Oleuem Fluorescent and sprayed two layers. Nothing fancy, but the rotating props are highly visible afterwards.

Yes, there is a set screw which looks tight to me. Also the shaft is aligned with the bottom the same as the other motors, maybe slightly more. I will check once I get the clips back in and also use a little lock tight for the set screw.

2 blades, both front blades. The clearly mark the front "face" of the copter.

crazyj another fine video. What is the silver material youre using to balance the props? What do you think about the motor and legs visible in your video - are you going to move things around or change the position of the gopro?

Thank you sir!

I built the Scarab WRONG with the front legs in front of the booms, they should have been behind the booms instead. I have already fixed this by switching the left and right legs - perfect!

The camera is mounted under the center section on a servo operated tilt mount. I can control the angle of tilt on a slider switch and easily get the motor out of the video frame.

Here's a pic showing the correct leg placement:


And quick pics of my camera mount & FPV stuff mounted:
