HeliCommand Rigid with a 5 Bladed Lightning Heli Head on a Tby AIRWORKSBYERIC3,184 views
very intersting. I RC helis in my spare time. I've been working on something using a trex and some off the shelf gyros + sensors, using picotux mini linux computer for the 'brain'.
I've got itto auto hover and have been experimenting with basic collision avoidance logic.
I'm curious to know what your setup is.
oh, and have you seen the helicommand autopiolt sytem. Wish I would have known about it before I set out down this path. Woulda saved me some time. LOL

I wish some people would understand the complexity of these things. Kids see me flying my t-rex 450 and want to fly. You tell them no and they go off thinking "who cant fly those toys". It can make you mad after a while of people thinking you are a jerk for not letting them fly.

Thank you for the comment geekdisk. The wag was present because I noticed a crack at the last moment and had to switch rotor blades to a different type (whatever I had available) before this experiment, and had no time to re-tune yaw PID to compensate new airfoil. Increasing rotor RPM has its complications: will make the aircraft more aggressive (thus ruining other PID tunings), and reduce endurance. Mechanics are free; gently blow on the flybar, and it will move. Airframe is grounded properly.

I noticed a slight tail wag. I have 6 of this model helicopter and am also working with the IARC, Army Institute of Technology is an Indian university on their MAV project for the Angel-strike contest in Puerto Rico this year.
Increasing the rpm of the rotor has solved our tail wag issues. Also making sure the mechanical parts are working as freely as possible. Also BEWARE of static discharge! Test your frame to assure everything has a common ground.
