I'm interested in pursuing this also. I've seen some projects, but so far all of them use draggy rotating (or even fixed) rotors for copter mode. What I have in mind is more like the V-22 Osprey, but with much more wing area for longer…"
"Many of us have tried that approach without any success. Please report back your results if by some miracle you get it to work :-) Reuben's circuit works and it is fairly easy to build, so I think that is what most people are doing. If you lack…"
"> I have read in a number of sources that the Ho IV suffered from stability issues due to an unforgiving C.O.G.
What I remember reading was that pilots complained about yaw stability or skidding in turns, something like that but my memory is a bit…"
"I second Andrew's comment. This is just Aerodynamics 101 stuff. A pure wing (Nurflugel) is more efficient by definition because the airframe is entirely devoted to generating lift. Fuselage and tail surfaces generate what aerodynamicists call…"
Great post and interesting angle on the Schulgleiter. I have always maintained that the best way to learn to fly is to start with gliders. That's how I started and it is the advice I have always given to new R/C pilots. Few of them…"
I designed, built and flew a scale model of the Ho IX/229 some years ago, and later participated in the making of the NatGeo documentary, "Hitler's Stealth Fighter". I had the opportunity to meet and talk to David Myhra at length, one of…"
"Installing the drivers is only half the problem. On my system, the drivers won't work (after installation) unless I boot with the driver signatures disabled!!! This is driving me crazy! I'm on a laptop which needs to be shutdown for transport, so…"
"I've built and tested Marco's circuit. It works. I'm giving up on the Sparkfun device until someone can post a wire diagram that has been tested and proven to work. Unfortunately I don't have a lot of time for experimentation. I'm going to…"
"Thanks. I'm still looking to prevent people from wasting time trying to get the Sparkfun device to work, since (like me) they might just look at the Wiki and assume (like me) that it will work in the way you would expect.
Craig? We're all busy,…"
"Replying to Craig Elder's post:
>>> I thought that supplying 5v to the servo rails via BEC (which is what I'm doing) would boost the current on the 3.3V Pixhawk output signal enough to make this
>No. The two are not related.…"
"The picture shows the same one I have. Is there another one? I thought that supplying 5v to the servo rails via BEC (which is what I'm doing) would boost the current on the 3.3V Pixhawk output signal enough to make this device (Sparkfun) put out a…"
"What a mess indeed. The wikis and forums are littered with false and misleading information on this topic. I wasted the better part of a weekend trying to get the Sparkfun voltage converter and/or a Turnigy relay switch to work. Even *with* good…"
