This is no different than "guns don't kill people, PEOPLE kill people." Someone has to take the tech and steer it towards some evil end. You can use a gun to get food, to defend yourself against evil does,…

A report on my images of local flooding. I haven't gotten an autopilot up and running yet, but am about to install auto-stabilization. Even with the footage I got, the local web news site was happy to get it. Video…See More

Hi, I got your message about the spar. I used two CF arrow shafts joined together for one ginormous spar. I get them USED for less than a dollar a piece from a local archery guy.

Ok, in the case of the guys "plane-pooling", is the pilot contributing his share by operating the craft? It clearly states "anything of value". I had considered trading farmers for foods they sell at the local farmers…

Ok, so how'd it go?? That has got to be the coolest sled I have ever seen, and might even work ok on water. I have a fanboat and ROV candidate, and am dying to know more about ground operations. Thanks, Tim

Doug, as always You da man!" That rig is nice! I wasn't saying two position switch is the way to go, just that it CAN be dealt with, I did. In all honesty, it really sucked to set it up that way, LOL! The dx7 is NICE, 2o model memory. Does…

Tim McMahan replied to Cong Do's discussion 'Help me to completed my scratchbuilt twinboom!!!'

Well, the Ardupilot selects different modes using the gear switch. SOME radiios have three positions, some have two. Generally, two is enough. Landing gear up and landing gear down. I did some custom mixing across channels 5 and 6 to get 3 positions…

Glad to hear about another Twin boom. I'm now workinig on a Version 2. Ii fly on on a JR 6channel rig, converted with a Coraona hack module so I can select 2.4 OR 72mhz. It flies great on either one. The thing to keep in mind is 1- How many…

Well, i made an EPP version of the Raven, but it was before any plans or 3-views were available. I had some definite issues, so I'll have to compare to see whats wrong with mine. Here's the video though.

Ive got one that Ill probably never use again. Had it for an eco 8 mechanical mixing heli. Bought it for 50, if you just want the brains, I could sell them for 25.

I assume you know they still sell them and that they have been reduced to $50+ http://www.store.revolectrix.com/Products/Co-Pilot-CPD4/Co-Pilot-CPD4_2
