You might look up Minnies yacht surplus, they have a ton of used bits and are very affordable! I think their website only has sails but believe me they have a lot more than that!
"There are several types of Autopilots for boats already in use including a couple that use stepper motors and a cog belt clamped to the spokes of the helm. These can be very cheap used/incomplete and already have a dependable means of disengagement.…"
"What would you like to do with it and where? I use an Axial Wraith (RTR version) and am pretty happy with it but it is kinda expensive if you're just looking for something to tinker with. Traxxas and Redcat both make inexpensive on and offroad…"
"Hmm yeah they probably would want some royalties on that.
I wonder if the uninterrupted airflow from a gimbaled setup might offset the weight? I think if you kept the rotational axies (sp?) centered between the two rotors it would require very…"
"Well I think you've pretty well summed it up Paul!
The million dollar question is: What do WE do?
Its apparent that the FAA is in no particular rush to get things done so I think your suggestion of a committee may be the best option. Obviously we…"
"Nice! What I meant by inverting the control planes was moving the pivot point to the leading (upper) edge. It looks like you have it setup for the trailing edge now and I would think that tend to put excessive load on the servo and encourage the…"
"Very cool man! How will this arrangement fit into the probe droid body? Are you thinking something along the lines of a ducted fan setup drawing through the vertical axis of the body? Also, I am wondering if it wouldnt be better to invert the…"
"What about a frequency already in use though? That way they wouldnt have to purchase anything and while it wouldnt alert us to their presence it would at least give them some warning. Keep in mind that while outfitting a single plane with a…"
"Surely there is a given set of frequencies for aircraft comms. Would it be so difficult to say that the lowest channel in the assigned frequency range would be for UAV transponders? Dont most comm radios installed in manned craft have the ability to…"
"@ Eric
I hadnt really thought about using our telemetry radios for this but that would seem like the easiest way to implement it. Perhaps some more knowledgeable person could write the code for this and we could just implement it ourselves?…"
"Forgive me if this is a noob question but is there nothing like AIS for aircraft? Its a simple system that could surely be downsized for use in UAV's and would certainly be easily employed in manned aircraft. AIS uses a relatively low power…"
