About Me:
I'm an aerospace engineer. I work as a flight test engineer for the Navy.
Please tell us a bit about your UAV interest
Interested in reprogramming a autopilot module to fly a scale RC V-22 model that I'm building.

"Thanks. I will pull tags and use that."
"I assume there is no stable released version for this 3.3 Trad Heli. Should I compile the master or is there a tag i can checkout and compile for the latest beta. I'd appreciate any help."
"Just wanted to provide an update in case any one has started to look at this. I was able to figure out the issue. The parameter.pde and parameter.h files were not right. Once I got them straightened out everything worked. I even got the proper…"
I have incorporated code to make use of the airspeed sensor in the arducopter software. I based the code changes on this posthttps://groups.google.com/forum/#!topic/drones-discuss/wzwCs3Xk7y4and help from the Tiltrotor Team who had done it for…
"After doing a little digging in the code. I found the line of code AP_Motors_Heli::Init that disables being able to use channel 7 for Aux channel functions. If I'm not using any of the tail types for channel 7, do you think it would be acceptable…"
"Randy,
Thanks for the response. Here is a log from a flight I did earlier today. I had increased the ATC rate and Accel max parameters because i thought the rate and accel limiting was causing the lag. I was using the channel 6 option to vary…"

I'm in the process of tuning my 4 bladed, 10 lb helicopter. I have the rate_xxx_p gains high enough that the Heli responds nicely in stabilize mode but when trying to fly in acro mode, the aircraft response is very lagged to my inputs. Even with…
"Rob,
I've currently have Copter 3.2.1 loaded and I don't see the RATE_ROLL_LPF parameter. Now there is a RATE_RLL_FF paramter. What is this parameter? What does it actually do? I have conducted a few short hovers with trying to tune the…"

I want to offer a way to remove the instability of the helicopter to RATE_RLL_P. I believe that this is caused by the lead-lag of the blades coupling with the body dynamics which is a well known rotor instability for manned helicopters. Could…
"This design is used by full scale manufacturers to achieve high speed forward flight. This design, for full scale helicopter, is limited by the advancing rotor tip speed going supersonic and retreating blade stall. For RC aircraft I'll primarily be…"
"Rob,
I have just started using a Pixhawk for a unique helicopter project in which it has two forward facing tailrotors rather than a traditional tailrotor. Benefit is that you can use them for directional control and forward thrust. I'm slowly…"

"I saw your post on another discussion regarding channel pass through. I will try the idea of using the camera mount tilt to use a higher output channel. a slightly lagged response may be acceptable for this forward thrust controller. At least it…"
"I am using a pixhawk but would I be able to do it with an 8 channel futaba receiver with a PPM encoder connecting the receiver to the pixhawk. I thought that the RC pass through only maps the corresponding input channel. Thanks for the help!!"
I have designed and built a unique helicopter that uses two forward facing tail rotors to provide anti-torque and directional control as well as forward thrust. I have a servo to controlling directional axis and another servo controlling forward…
"Randy,
So I went back and compiled a hil version of copter 3.2 for Quad and Heli frames. I played with the quad frame in x-plane. I had to disable the prearm checks and the state info was coming across and I got the Pixhawk to arm. Of course the…"
